1 Getting Started Dell EMC Networking OS10 Enterprise Edition is a network operating system supporting multiple architectures and environments. The networking world is moving from a monolithic stack to a pick-your-own-world. The OS10 solution is designed to allow disaggregation of the network functionality.
Download OS10 image and license OS10 Enterprise Edition may come factory-loaded and is available for download from the Dell Digital Locker (DDL). A factory-loaded OS10 image has a perpetual license installed. An OS10 image that you download has a 120-day trial license and requires a perpetual license to run beyond the trial period. See the Quick Start Guide shipped with your device and My Account FAQs for more information.
Once you download the OS10 Enterprise Edition image, unzip the .tar file. Some Windows unzip applications insert extra carriage returns (CR) or line feeds (LF) when they extract the contents of a .tar file, which may corrupt the downloaded OS10 binary image. Turn off this option if you use a Windows-based tool to untar an OS10 binary file. Once you unzip the OS10 Enterprise Edition and download the license, see Installation and Install license for complete installation and license information.
the switch from ONIE for any reason other than installation, select the ONIE: Rescue or ONIE: Update ONIE option from the ONIE boot menu. CAUTION: During an automatic or manual OS10 installation, if an error condition occurs that results in an unsuccessful installation, perform Uninstall OS first to clear the partitions if there is an existing OS on the device. If the problem persists, contact Dell EMC Technical Support.
4 Create a USB mount location on the system. $ mkdir /mnt/media 5 Identify the path to the USB drive. $ fdisk -l 6 Mount the USB media plugged in the USB port on the device. $ mount -t vfat usb-drive-path /mnt/media 7 Install the software from the USB, where /mnt/media specifies the path where the USB partition is mounted. $ onie-nos-install /mnt/media/image_file The ONIE auto-discovery process discovers the image file at the specified USB path, loads the software image, and reboots.
• http://hostip/filepath — Copy from a remote HTTP server • http://hostip — Send request to a remote HTTP server. • localfs://filepath — Install from a local file directory. • scp://userid:passwd@hostip/filepath — Copy from a remote SCP server. • sftp://userid:passwd@hostip/filepath — Copy from a remote SFTP server. • tftp://hostip/filepath — Copy from a remote TFTP server. • usb://filepath — Install from a file directory on a storage device connected to the USB storage port on the switch.
Remote access OS10 CLI 1 Open an SSH session using the IP address of the device. You can also use PuTTY or a similar tool to access the device remotely. ssh admin@ip-address password: admin 2 Enter admin for both the default user name and password to log into OS10. You are automatically placed in EXEC mode. OS10# Remote access Linux shell ssh linuxadmin@ip-address password: linuxadmin Configure Management IP address To remotely access OS10, assign an IP address to the management port.
• ipv6-address/prefix-length — Enter an IPv6 address in x:x:x:x::x format with the prefix length in /x format. The prefix range is /0 to /128. • forwarding-router-address — Enter the next-hop IPv4/IPv6 address of a forwarding router for network traffic from the Management port. • managementethernet — Configures the Management port as the interface for the route, and associates the route with the Management interface. Configure management route OS10(config)# management route 10.10.20.0/24 10.1.1.
6 Select how you want to download the software files, then click Download Now. Install the OS10 image on an ONIE-enabled switch with an installed OS10 license. See Install OS10 license for complete instructions. CLI Basics The OS10 command-line interface (CLI) is the software interface you use to access a device running the software — from the console or through a network connection. The CLI is an OS10-specific command shell that runs on top of a Linux-based operating system kernel.
• When a session terminates while in the transaction-based configuration mode, and you have not entered the commit command, the changes are maintained in the candidate configuration. You can start a new transaction-based configuration session and continue with the remaining configuration changes. • All sessions in the transaction-based configuration mode update the same candidate configuration.
From CONFIGURATION mode, you can also configure L2 and L3 protocols with a specific protocol-configuration mode, such as spanningtree protocol (STP) or border gateway protocol (BGP). Command help To view a list of valid commands for any CLI mode, enter ? or the help command. 1 Enter ? to view the commands available in EXEC mode.

2 Interfaces You can configure and monitor physical interfaces (Ethernet), port-channels, and virtual local area networks (VLANs) in Layer 2 (L2) or Layer 3 (L3) modes. Table 1.
A Trunk interface carries VLAN traffic that is tagged using 802.1q encapsulation. If an Access interface receives a packet with an 802.1q tag in the header that is different from the Access VLAN ID, it drops the packet. By default, a trunk interface carries only untagged traffic on the Access VLAN. You must manually configure other VLANs for tagged traffic. 1 2 Select one of the two available options: • Configure L2 trunking in INTERFACE mode and the tagged VLAN traffic that the port can transmit.
Figure 1. S4148U-ON port groups On a S4148U-ON, the activated FC interfaces depend on the currently configured port profile. For more information, see S4148U-ON port profiles. To enable a fibre channel interface: 1 Configure a unified port group in CONFIGURATION mode. Enter 1/1 for node/slot. The port-group range is 1–10. port-group node/slot/port-group 2 Activate the unified port group for FC operation in PORT-GROUP mode.
Address is 14:18:77:20:8d:fc, Current address is 14:18:77:20:8d:fc Pluggable media present, QSFP-PLUS type is QSFPPLUS_4X16_16GBASE_FC_SW Wavelength is 850 Receive power reading is 0.
Configure VLAN OS10(config)# interface vlan 10 OS10(conf-if-vl-10)# ip address 1.1.1.2/24 You cannot simultaneously use egress rate shaping and ingress rate policing on the same VLAN. User-configured default VLAN By default, VLAN1 serves as the default VLAN for switching untagged L2 traffic on OS10 ports in Trunk or Access mode. The default VLAN is used for untagged protocol traffic sent and received between switches, such as STPs.
Hardware is unknown. Interface index is 102863300 Internet address is 120.120.120.
Add port member When you add a port interface to a port-channel: • The port-channel configuration and administrative status are applied to member interfaces. • A port-channel operates in either L2 (default) or L3 mode. To place a port-channel in L2 mode, use the switchport mode command. To place a port-channel in L3 mode and remove L2 configuration before you configure an IP address, use the no switchport command. • All interfaces should have the same speed (recommended).
Configure minimum operationally up links OS10(config)# interface po 1 OS10(conf-if-po-1)# minimum-links 5 Assign IP address Assign an IP address to a port-channel and use port-channels in L3 routing protocols. • Configure an IP address and mask for the interface in INTERFACE mode. Use the secondary parameter to configure up to eight secondary IP addresses, if needed. ip address A.B.C.D/x [secondary] Assign port-channel IP address OS10(config)# interface port-channel 10 OS10(conf-if-po10)# ip address 1.1.
– ipv6-selection [destination-ip | source-ip | protocol | vlan-id | l4–destination-port | l4– source-port] — Uses the destination IPv6 address, source IPv6 address, protocol, VLAN ID, Layer 4 destination IPv6 address, or Layer 4 source IPv6 address in the hash calculation. – mac—selection [destination-mac | source-mac] [ethertype | vlan-id] — Uses the destination MAC address or source MAC address, and ethertype, or VLAN ID in the hash calculation.

profile-2 profile-3 profile-4 profile-5 profile-6 S4148-ON Series port profiles On the S4148-ON Series of switches, port profiles determine the available front-panel Ethernet ports and supported breakout interfaces on uplink ports. In the port profile illustration, blue boxes indicate the supported ports and breakout interfaces. Blank spaces indicate ports and speeds that are not available. • • • • • 10GE mode is an SFP+ 10GE port or a 4x10G breakout of a QSFP+ or QSFP28 port.
Fibre Channel port modes and breakout interfaces. Blank spaces indicate ports and speeds that are not available. Unified port groups are numbered 1 to 10. S4148U-ON unified port modes—SFP+ ports 1-24 and QSFP28 ports 25-26 and 29-30: • 10GE is an SFP+ port in Ethernet mode or a 4x10G breakout of a QSFP+ or QSFP28 port in Ethernet mode. • 25GE is a 4x25G breakout of a QSFP28 Ethernet port. • 40GE is a QSFP+ or QSFP28 Ethernet port that uses QSFP+ 40GE transceivers.
• QSFP28 ports in 4x16GFC mode support 32GFC oversubscription. Breakout interfaces: • To configure breakout interfaces on a unified port, use the mode {FC | Eth} command in Port-Group Configuration mode. The mode {FC | Eth} command configures a unified port to operate at line rate and guarantees no traffic loss. • To configure breakout interfaces on a QSFP+ Ethernet port, use the interface breakout command in global Configuration mode.

Auto-negotiation performs at power-up, on command from the LAN controller, on detection of a PHY error, or following Ethernet cable reconnection. During the link establishment process, both link partners indicate their EEE capabilities. If EEE is supported by both link partners for the negotiated PHY type, EEE functions independently in either direction. Changing the EEE configuration resets the interface because the device restarts Layer 1 auto-negotiation.

The F_Port and NPG modes are mutually exclusive. If you have already configured a vfabric in F_Port mode, while configuring vfabrics in NPG mode, disable the F_Port mode. The existing vfabric is removed when you disable F_Port mode and you need to configure new vfabrics in NPG mode. If you are moving from NPG mode to F_Port mode, then disable the NPG mode and create new vfabric in F_Port mode. Zoning allows you to increase network security by partitioning the devices connected to the vfabric into subsets.

4 Layer 2 802.1X Verifies device credentials prior to sending or receiving packets using the extensible authentication protocol (see 802.1X Commands). Link Aggregation Control Protocol (LACP) Exchanges information between two systems and automatically establishes a LAG between the systems (see LACP Commands). Link Layer Discovery Enables a LAN device to advertise its configuration and receive configuration information from adjacent LLDPProtocol (LLDP) enabled infrastructure devices (see LLDP Commands).
NOTE: OS10 supports only RADIUS as the back-end authentication server. The authentication process involves three devices: • Supplicant — The device attempting to access the network performs the role of supplicant. Regular traffic from this device does not reach the network until the port associated to the device is authorized. Prior to that, only the supplicant can exchange 802.1x messages (EAPOL frames) with the authenticator.
6 If the identity information the supplicant provides is valid, the authentication server sends an Access Accept frame in which network privileges are specified. The authenticator changes the port state to authorize and forwards an EAP Success frame. If the identity information is invalid, the server sends an Access Reject frame. If the port state remains unauthorized, the authenticator forwards an EAP Failure frame. EAP over RADIUS 802.
Enable 802.1X 1 Enable 802.1X globally in CONFIGURATION mode. dot1x system-auth-control 2 Enter an interface or a range of interfaces in INTERFACE mode. interface range 3 Enable 802.1X on the supplicant interface only in INTERFACE mode. dot1x port-control auto Configure and verify 802.
Identity retransmissions If the authenticator sends a Request Identity frame but the supplicant does not respond, the authenticator waits 30 seconds and then retransmits the frame. There are several reasons why the supplicant might fail to respond — the supplicant may have been booting when the request arrived, there may be a physical layer problem, and so on.
Failure quiet period If the supplicant fails the authentication process, the authenticator sends another Request Identity frame after 30 seconds by default. The quiet period is a transmit interval time after a failed authentication. The Request Identity Re-transmit interval is for an unresponsive supplicant. You can configure the interval for a maximum of 10 times for an unresponsive supplicant.
force-authorized (default) This is an authorized state. A device connected to this port does not use the authentication process but can communicate on the network. Placing the port in this state is same as disabling 802.1X on the port. forceauthorized is the default mode. force-unauthorized This is an unauthorized state. A device connected to a port does not use the authentication process but is not allowed to communicate on the network.

Aggregating multiple links between physical interfaces creates a single logical LAG, which balances traffic across the member links within an aggregated Ethernet bundle and increases the uplink bandwidth. If one member link fails, the LAG continues to carry traffic over the remaining links.

LAN devices transmit LLDPDUs, which encapsulate TLVs, to neighboring LAN devices. LLDP is a one-way protocol and LAN devices (LLDP agents) transmit and/or receive advertisements but they cannot solicit and do not respond to advertisements. There are three mandatory TLVs followed by zero or more optional TLVs and the end of the LLDPDU TLV.
Organizationally-specific TLVs There are eight TLV types defined by the 802.1 and 802.3 working groups as a basic part of LLDP. Configure OS10 to advertise any or all of these TLVs. Optional TLVs 4 — Port description User-defined alphanumeric string that describes the port. 5 — System name User-defined alphanumeric string that identifies the system. 6 — System description Detailed description of all components of the system. 7 — System capabilities Determines the capabilities of the system.
Media endpoint discovery LLDP media endpoint discovery (LLDP-MED) provides additional organizationally-specific TLVs to allow endpoint devices and network connectivity devices to advertise their characteristics and configuration information. LLDP-MED endpoint devices are located at the IEEE 802 LAN network edge and participate in IP communication service using the LLDPMED framework, such as IP phones and conference bridges.

By default, each VLAN instance is assigned default bridge priority 32768. For example, all three instances have the same forwarding topology. Traffic load balancing is not achievable with this kind of priority assignment. You must assign each instance a different priority to achieve load balancing, as shown in Load Balancing with RPVST+. Load balance and root selection All VLANs use the same forwarding topology — R2 is elected as the root and all 10G Ethernet ports have the same cost.

Remote port monitoring on VLT In a network, devices configured with peer VLT nodes are considered as a single device. You can apply remote port monitoring (RPM) on the VLT devices in a network. In a failover case, the monitored traffic reaches the packet analyzer connected to the TOR through the VLT interconnect link. NOTE: • In VLT devices configured with RPM, when the VLT link is down, the monitored packets might drop for some time.

5 Layer 3 Border Gateway Protocol (BGP) Provides an external gateway protocol that transmits inter-domain routing information within and between autonomous systems (see BGP Commands). Equal Cost MultiPath (ECMP) Provides next-hop packet forwarding to a single destination over multiple best paths (see ECMP Commands). IPv4 Routing Provides forwarding of packets to a destination IP address, based on a routing table.
Classless interdomain routing BGPv4 supports classless interdomain routing (CIDR) with aggregate routes and AS paths. CIDR defines a network using a prefix consisting of an IP address and mask, resulting in efficient use of the IPv4 address space. Using aggregate routes reduces the size of routing tables. Path-vector routing BGP uses a path-vector protocol which maintains dynamically updated path information. Path information updates which return to the originating node are detected and discarded.
After the connection is established, the router sends and receives keepalive, update, and notification messages to and from its peer. Peer templates Peer templates allow BGP neighbors to inherit the same outbound policies. Instead of manually configuring each neighbor with the same policy, you can create a peer group with a shared policy that applies to individual peers. A peer template provides efficient update calculation with simplified configuration. Peer templates also aid in convergence speed.
BGP session supports multiple address family interface (AFI) and sub address family interface (SAFI) combinations, BGP uses OPEN message to convey this information to the peers. As a result, the IPv6 routing information is exchanged over the IPv4 peers and vice versa. BGP routers that support IPv6 can set up BGP sessions using IPv6 peers. If the existing BGP-v4 session is capable of exchanging ipv6 prefixes, the same is used to carry ipv4 as well as ipv6 prefixes.
6 Prefer external (EBGP) to internal (IBGP) paths or confederation EBGP paths, and prefer the path with the lowest IGP metric to the BGP next-hop. 7 The system deems the paths as equal and only performs the following steps if the criteria are not met: 8 • Configure the IBGP multipath or EBGP multipath using the maximum-path command. • The paths being compared were received from the same AS with the same number of AS in the AS Path but with different nexthops.
Multiexit discriminators If two autonomous systems connect in more than one place, use a multiexit discriminator (MED) to assign a preference to a preferred path. MED is one of the criteria used to determine best path—other criteria may also impact selection. One AS assigns the MED a value. Other AS uses that value to decide the preferred path. Assume that the MED is the only attribute applied and there are two connections between AS 100 and AS 200. Each connection is a BGP session.
AS path and next-hop The AS path is the AS list that all the prefixes listed in the update have passed through. The BGP speaker adds the local AS number when advertising to an EBGP neighbor. Any update that contains the AS path number 0 is valid. The next-hop is the IP address used to reach the advertising router: • For EBGP neighbors, the next-hop address is the IP address of the connection between neighbors. • For IBGP neighbors, the EBGP next-hop address is carried into the local AS.
More path support More path (Add-Path) reduces convergence times by advertising multiple paths to its peers for the same address prefix without replacing existing paths with new ones. By default, a BGP speaker advertises only the best path to its peers for a given address prefix. If the best path becomes unavailable, the BGP speaker withdraws its path from its local router information base (RIB) and recalculates a new best path. This situation requires both IGP and BGP convergence and is a lengthy process.
4-Byte AS numbers OS10 supports 4-byte AS number configurations by default. The 4-byte support is advertised as a new BGP capability - 4-BYTE-AS, in the OPEN message. A BGP speaker that advertises 4-Byte-AS capability to a peer, and receives the same from that peer must encode AS numbers as 4-octet entities in all messages. If the AS number of the peer is different, the 4-byte speaker brings up the neighbor session using a reserved 2-byte ASN,23456 called AS_TRANS.
The Local-AS does not prepend the updates with the AS number received from the EBGP peer if you use the no prepend command. If you do not select no prepend, the default, the Local-AS adds to the first AS segment in the AS-PATH. If you use an inbound route-map to prepend the AS-PATH to the update from the peer, the Local-AS adds first. If Router B has an inbound route-map applied on Router C to prepend 65001 65002 to the AS-PATH, these events take place on Router B: • • • Receive and validate the update.

As with route reflectors, Dell EMC recommends BGP confederations only for IBGP peering involving many IBGP peering sessions per router. When you configure BGP confederations, you break the AS into smaller sub-ASs. To devices outside your network, the confederations appear as one AS.
Route dampening When EBGP routes become unavailable, they “flap” and the router issues both WITHDRAWN and UPDATE notices. A flap occurs when a route is withdrawn, readvertised after being withdrawn, or has an attribute change. The constant router reaction to the WITHDRAWN and UPDATE notices causes instability in the BGP process. To minimize this instability, configure penalties (a numeric value) for routes that flap.

Link-local addresses When an OS10 switch boots up, an IPv6 unicast link-local address is automatically assigned to an interface using stateless configuration. A link-local address allows IPv6 devices on a local link to communicate without requiring a globally unique address. IPv6 reserves the address block FE80::/10 for link-local unicast addressing. Global addresses To enable stateless autoconfiguration of an IPv6 global address and set the interface to Host mode, use the ipv6 address autoconfig command.
Stateless autoconfiguration of IPv6 addresses is performed using: Prefix advertisement Routers use router advertisement messages to advertise the network prefix. Hosts append their interface-identifier MAC address to generate a valid IPv6 address. Duplicate address detection An IPv6 host node checks whether that address is used anywhere on the network using this mechanism before configuring its IPv6 address.
3 • ipv6 nd ra-lifetime seconds — (Optional) Sets the lifetime of a default router in RA messages (0 to 9000 milliseconds; default 3 times the max-ra-interval setting). 0 indicates that this router is not used as a default router. • ipv6 nd reachable-time milliseconds — (Optional) Sets the advertised time for which the router sees that a neighbor is up after it receives neighbor reachability confirmation (0 to 3600000 milliseconds; default 0). 0 indicates that no reachable time is sent in RA messages.
To disable IPv6 on an interface when a duplicate link-local address is detected, use the ipv6 nd dad disable-ipv6-on-failure command. To re-enable IPv6 after you resolve a duplicate link-local address, enter no ipv6 enable, followed by ipv6 enable. • Disable or re-enable IPv6 duplicate address discovery in Interface mode. ipv6 nd dad {disable | enable} • Disable IPv6 on an interface if a duplicate link-local address is discovered in Interface mode.
Enable IPv6 unreachable destination messaging OS10(config)# interface ethernet 1/1/8 OS10(conf-if-eth1/1/8)# ipv6 unreachables IPv6 hop-by-hop options A hop-by-hop header extension in an IPv6 packet contains options that are processed by all IPv6 routers in the packet's path. By default, hop-by-hop header options in an IPv6 packet are not processed locally. To enable local processing of IPv6 hop-by-hop options on an interface, use the ipv6 hop-by-hop command.
clear ipv6 route Clears routes from the IPv6 routing table. Syntax Parameters clear ipv6 route {* | A::B/mask} • *— Clears all routes and refreshes the IPv6 routing table. Traffic flow for all the routes in the switch is affected. • A::B/mask — Removes the IPv6 route and refreshes the IPv6 routing table. Traffic flow in the switch is affected only for the specified route.
Command Mode Usage Information INTERFACE • This command sets an interface in Host mode to perform IPv6 stateless auto-configuration by discovering prefixes on local links, and adding an EUI-64 based interface identifier to generate each IPv6 address. The command disables IPv6 forwarding. Addresses are configured depending on the prefixes received in router advertisement messages.
ipv6 address eui-64 Configures a global IPv6 address on an interface by entering only the network prefix and length. Syntax ipv6 address ipv6-prefix/prefix-length eui-64 Parameters ipv6-prefix — Enter an IPv6 prefix in x:x::y/mask format. Defaults None Command Mode INTERFACE Usage Information Use this command to manually configure an IPv6 address in addition to the link-local address generated with stateless autoconfiguration. Specify only the network prefix and length.

Areas allow you to further organize routers within the AS with one or more areas within the AS. Areas are valuable in that they allow subnetworks to hide within the AS—minimizing the size of the routing tables on all routers. An area within the AS may not see the details of another area’s topology. An area number or the router’s IP address identifies AS areas. Areas, networks, and neighbors The backbone of the network is Area 0, also called Area 0.0.0.0, the core of any AS.
Router types Router types are attributes of the OSPF process—multiple OSPF processes may run on the same router. A router connected to more than one area, receiving routing from a BGP process connected to another AS, acts as both an area border router and an autonomous system border router. Each router has a unique ID, written in decimal format—A.B.C.D. You do not have to associate the router ID with a valid IP address.
Designated and backup designated routers OSPF elects a designated router (DR) and a backup designated router (BDR). The DR is responsible for generating LSAs for the entire multiaccess network. Designated routers allow a reduction in network traffic and in the size of the topological database. Designated router Maintains a complete topology table of the network and sends updates to the other routers via multicast. All routers in an area form a slave/master relationship with the DR.
(OSPFv2), IntraArea Prefix LSA (OSPFv3) Type 11—Grace LSA Link-local opaque LSA for OSPFv3 only is sent during a graceful restart by an OSPFv3 router. (OSPFv3) The LSA header is common to LSA types. Its size is 20 bytes. One of the fields of the LSA header is the link-state ID. Each router link is defined as one of four types—type 1, 2, 3, or 4. The LSA includes a link ID field that identifies the object this link connects to, by the network number and mask.
Shortest path first throttling Use shortest path first (SPF) throttling to delay SPF calculations during periods of network instability. In an OSPF network, a topology change event triggers an SPF calculation that is performed after a start time. When the start timer finishes, a hold time can delay the next SPF calculation for an additional time.
SPF schedule delay 1345 msecs, Hold time between two SPFs 2324 msecs Min LSA origination 5000 msec, Min LSA arrival 1000 msec Min LSA hold time 0 msec, Max LSA wait time 0 msec Number of area in this router is 1, normal 1 stub 0 nssa Area (0.0.0.1) Number of interface in this area is 1 SPF algorithm executed 2 times OSPFv2 OSPFv2 supports IPv4 address families. OSPFv2 routers initially exchange hello messages to set up adjacencies with neighbor routers.

Policy-based routing Policy-based routing (PBR) provides a mechanism to redirect IPv4 and IPv6 data packets based on the policies defined to override the switch’s forwarding decisions based on the routing table. Policy-based route-maps A route-map is an ordered set of rules that control the redistribution of IP routes into a protocol domain. When you enable PBR on an interface, all IPv4 or IPv6 data packets received are processed based on the policies that you define in the route-maps.

Configuration VRRP specifies a master (active) router that owns the next hop IP and MAC address for end stations on a LAN. The master router is chosen from the virtual routers by an election process and forwards packets sent to the next hop IP address. If the master router fails, VRRP begins the election process to choose a new master router which continues routing traffic. VRRP packets are transmitted with the virtual router MAC address as the source MAC address.
Create virtual router VRRP uses the VRID to identify each virtual router configured. Before using VRRP, you must configure the interface with the primary IP address and enable it. • Create a virtual router for the interface with the VRRP identifier in INTERFACE mode (1 to 255). vrrp-group vrrp-id • Delete a VRRP group in INTERFACE mode.
Set backup switches to VRRPv3 OS10_backup_switch1(config)# vrrp version 3 OS10_backup_switch2(config)# vrrp version 3 Virtual IP addresses Virtual routers contain virtual IP addresses configured for that VRRP group (VRID). A VRRP group does not transmit VRRP packets until you assign the virtual IP address to the VRRP group. To activate a VRRP group on an interface, configure at least one virtual IP address for a VRRP group.

Usage Information To guarantee that a VRRP group becomes master, configure the VRRP group’s virtual address with same IP address as the interface’s primary IP address, and change the priority of the VRRP group to 255. If you set this command to 255 and the virtual-address is not equal to the interface’s primary IP address, the system displays an error message. The no version of this command resets the value to the default (100). Example OS10(conf-eth1/1/5-vrid-254)# priority 200 Supported Releases 10.
• priority cost value — (Optional) Enter a cost value to subtract from the priority value (1 to 254) Default 10 Command Mode INTERFACE-VRRP Usage Information If the interface is disabled, the cost value subtracts from the priority value and forces a new Master election. This election process is applicable when the priority value is lower than the priority value in the Backup virtual router. The no version of this command resets the value to the default.
enter or delete the virtual-address command. To guarantee that a VRRP group becomes Master, configure the VRRP group’s virtual address with the same IP address as the interface’s primary IP address and change the priority of the VRRP group to 255. You can ping the virtual addresses configured in all VRRP groups. The no version of this command deletes one or more virtual-addresses configured in the system. Example OS10(conf-eth1/1/5-vrid-254)# virtual address 10.1.1.15 Supported Releases 10.2.
Default Not configured Command Mode INTERFACE-VRRP Usage Information The VRRP group only becomes active and sends VRRP packets when you configure a virtual IP address. When you delete the virtual address, the VRRP group stops sending VRRP packets. The no version of this command removes the vrrp-ipv6–group configuration. Example OS10(conf-if-eth1/1/7)# vrrp-ipv6-group 250 Supported Releases 10.2.0E or later vrrp version Sets the VRRP protocol version for the IPv4 group.
6 UFT modes Unified Forwarding Table (UFT) gives the flexibility to configure the sizes of internal L2/L3 forwarding tables of a switch to match the needs of particular network environment. A switch in a Layer 2 network may require a larger MAC address table size, while a switch in a Layer 3 network may require a larger routing table size. OS10 supports several UFT modes for the forwarding tables. By default, OS10 selects a UFT mode which provides a reasonable size for all tables.
• Disable UFT mode in CONFIGURATION mode.
Parameters None Defaults None Command Mode EXEC Usage Information Use this command to view the current hardware forwarding table mode and the mode after the next boot. Example OS10# show hardware forwarding-table mode Current Settings Mode default-mode L2 MAC Entries : 163840 L3 Host Entries : 147456 L3 Route Entries : 16384 Supported Releases Next-boot Settings scaled-l3-hosts 98304 212992 98304 10.3.
7 System management Dynamic host configuration protocol Provides information to dynamically assign IP addresses and other configuration parameters to network hosts based on policies (see DHCP commands). Network time protocol Provides information about how to synchronize timekeeping between time servers and clients (see NTP commands). Security Provides information about role-based access control, RADIUS server, user roles, and user names (see Security eommands).
The table shows common options using DHCP packet formats.
DHCP automates network-parameter assignment to network devices. Even in small networks, DHCP is useful because it makes it easier to add new devices to the network. The DHCP access service minimizes the overhead required to add clients to the network by providing a centralized, server-based setup. This setup means you do not have to manually create and maintain IP address assignments for clients.
Address lease time Use the lease {days [hours] [minutes] | infinite} command to configure an address lease time (default 24 hours). OS10(config)# ip dhcp server OS10(conf-dhcp)# pool Dell OS10(conf-dhcp-Dell)# lease 36 Default gateway Ensure the IP address of the default router is on the same subnet as the client. 1 Enable DHCP server-assigned dynamic addresses on an interface in CONFIGURATION mode. ip dhcp server 2 Create an IP address pool and provide a name in DHCP mode.
NetBIOS WINS address resolution DHCP clients can be one of four types of NetBIOS nodes — broadcast, peer-to-peer, mixed, or hybrid. Dell EMC recommends using hybrid as the NetBIOS node type. 1 Enable DHCP server-assigned dynamic addresses on an interface in DHCP mode. ip dhcp server 2 Create an IP address pool and enter the pool name in DHCP mode. pool name 3 Enter the NetBIOS WINS name servers in order of preference that are available to DHCP clients in DHCP mode.

8 Access Control Lists OS10 uses two types of access policies — hardware-based ACLs and software-based route-maps. Use an ACL to filter traffic and drop or forward matching packets. To redistribute routes that match configured criteria, use a route-map. ACLs ACLs are a filter containing criterion to match; for example, examine IP, TCP, or UDP packets, and an action to take such as forwarding or dropping packets at the NPU. ACLs permit or deny traffic based on MAC and/or IP addresses.
NOTE: Hot-lock ACLs support ingress ACLs only. MAC ACLs MAC ACLs filter traffic on the Layer 2 (L2) header of a packet. This traffic filtering is based on: Source MAC packet address MAC address range—address mask in 3x4 dotted hexadecimal notation, and any to denote that the rule matches all source addresses. Destination MAC packet address MAC address range—address-mask in 3x4 dotted hexadecimal notation, and any to denote that the rule matches all destination addresses.
L3 ACL rules Use ACL commands for L3 packet filtering. TCP packets from host 10.1.1.1 with the TCP destination port equal to 24 are permitted, and all others are denied. TCP packets that are first fragments or non-fragmented from host 10.1.1.1 with the TCP destination port equal to 24 are permitted, and all TCP non-first fragments from host 10.1.1.1 are permitted. All other IP packets that are non-first fragments are denied.
User-provided sequence number • Enter IP ACCESS LIST mode by creating an IP ACL in CONFIGURATION mode. ip access-list access-list-name • Configure a drop or forward filter in IPV4-ACL mode.
Table 7. L2 and L3 targeted traffic L2 ACL / L3 ACL Targeted traffic Deny / Deny L3 ACL denies Deny / Permit L3 ACL permits Permit / Deny L3 ACL denies Permit / Permit L3 ACL permits Assign and apply ACL filters To filter an Ethernet interface, a port-channel interface, or a VLAN, assign an IP ACL filter to a physical interface. The IP ACL applies to all traffic entering a physical or port-channel interface.
• Apply the ACL as an inbound or outbound ACL on an interface in CONFIGURATION mode, and view the number of packets matching the ACL. show ip access-list {in | out} Ingress ACL filters To create an ingress ACL filter, use the ip access-group command in EXEC mode. To configure ingress, use the in keyword. Apply rules to the ACL with the ip access-list acl-name command. To view the access-list, use the show access-lists command.
ethernet1/1/29 seq 10 deny ip any any fragment count (100 packets) Clear access-list counters Clear IPv4, IPv6, or MAC access-list counters for a specific access-list or all lists. The counter counts the number of packets that match each permit or deny statement in an access-list. To get a more recent count of packets matching an access-list, clear the counters to start at zero. If you do not configure an access-list name, all IP access-list counters clear.
Route-maps Route-maps a series of commands that contain a matching criterion and action. They change the packets meeting the matching criterion. ACLs and prefix-lists can only drop or forward the packet or traffic while route-maps process routes for route redistribution. For example, use a route-map to filter only specific routes and to add a metric. • Route-maps also have an implicit deny.

9 Quality of service Quality of service (QoS) reserves network resources for highly critical application traffic with precedence over less critical application traffic. QoS enables to prioritize different types of traffic and ensures the required level of quality of service. You can control the following parameters of selected traffic flows: Delay, Bandwidth, Jitter, and Drop.
Configuring QoS is a three-step process: 1 2 Create class-maps to classify the traffic flows. The following are the different types of class-maps: • qos (default)—Classifies the ingress data traffic. • queuing —Classifies the egress queues. • control-plane—Classifies the control-plane traffic. • network-qos—Classifies the set of traffic-class IDs for ingress buffer configurations. • application —Classifies the application type traffic.
• Queuing policies must be applied in the output direction on physical interfaces or on system-qos mode. • Application type policy-map must be applied on system-qos mode. When a policy is applied on system, the policy is effective on all the ports in the system. However, interface level policy gets precedence over system level policy. Ingress traffic classification Ingress traffic can be either data traffic or control traffic.
2 Define the set of dot1p values mapped to traffic-class (qos-group) ID. OS10(config-tmap-dot1p-map)# qos-group 3 dot1p 0-4 OS10(config-tmap-dot1p-map)# qos-group 5 dot1p 5-7 3 Verify the map entries.

DSCP values TC id Color 52-55 6 Y 56-59 7 G 60-62 7 Y 63 7 R User–defined DCSP trust map You can override the default mapping by creating a user defined DSCP trust map. All the unspecified DSCP entries are mapped to the default traffic class ID 0. Configure user–defined DSCP trust map 1 Create a DSCP trust map.
3 Define trust type to be enabled. OS10(config-pmap-c-qos)# trust dot1p 4 Attach the policy-map to interface or system-qos level to make the trusting effective. • Interface level OS10(conf-if-eth1/1/1)# service-policy input type qos trust • System-qos level OS10(config-sys-qos)# service-policy input type qos trust ACL based classification Classify the ingress traffic by matching the packet fields using ACL entries.
• Pre-defined IP access-list OS10(config-cmap-qos)# match ip access-group name ip-acl-1 • Pre-defined MAC access-list OS10(config-cmap-qos)# match mac access-group name mac-acl-1 3 Create a qos type policy-map to refer the classes. OS10(config)# policy-map cos-policy 4 Refer the class-maps in the policy-map and define the required action for the flows.
CoPP applies policy actions on all control-plane traffic. The control-plane class map does not use any match criteria. To enforce rate-limiting or rate policing on control-plane traffic, create policy maps. You can use the control-plane command to attach the CoPP service policies directly to the control-plane. The default rate limits apply to 12 CPU queues and the protocols mapped to each CPU queue. The control packet type to CPU ports control queue assignment is fixed.
3 Create an input policy-map to assign the QoS policy to the desired service queues in CONFIGURATION mode. policy-map type control-plane policy-map-name 4 Associate a policy-map with a class-map in POLICY-MAP mode. class class-name 5 Configure marking for a specific queue number in POLICY-MAP-CLASS-MAP mode (0 to 11). set qos-group queue-number 6 Configure rate policing on incoming traffic in POLICY-MAP-CLASS-MAP mode.

Peak rate is the maximum rate for traffic arriving or leaving an interface under normal traffic conditions. Peak burst size indicates the maximum size of unused peak bandwidth that is aggregated. This aggregated bandwidth enables brief durations of burst traffic that exceeds the peak rate.
OS10(config-pmap-c-qos)# set qos-group 3 OS10(config-pmap-c-qos)# set color yellow Modify packet fields You can modify the value of CoS or DSCP fields. 1 Create a QoS type class-map to match a traffic flow OS10(config)# class-map cmap-dscp-3 OS10(config-cmap-qos)# match ip dscp 3 2 Modify the policy-map to update the DSCP field.
5 Configure a queuing class in POLICY-MAP mode. class class-name 6 Assign a bandwidth percent (1 to 100) to nonpriority queues in POLICY-MAP-CLASS-MAP mode.
2 Enter the output service-policy in SYSTEM-QOS mode or INTERFACE mode.
The buffer usage accounting happens for ingress packets on ingress pools and egress packets on egress pool. You can configure ingress packets buffer accounting per priority-group and egress packet buffer accounting per queue level. Configure ingress buffer Default settings In the default settings for ingress buffers, all traffic classes are mapped to the default priority group and the buffers are reserved per default priority group ID 7.

Default Not configured Command Mode CONFIGURATION Usage Information The no version of this command removes the WRED profile.
10 Virtual link trunking Virtual link trunking (VLT) is a Layer 2 (L2) aggregate protocol between end devices (servers) connected to different network devices. VLT reduces the role of spanning tree protocols (STPs) by allowing link aggregation group (LAG) terminations on two separate distribution or core switches and supporting a loop-free topology.
VLT physical ports 802.1p, 802.1q, LLDP, flow control, port monitoring, and jumbo frames are supported on VLT physical ports. System management protocols All system management protocols are supported on VLT ports — SNMP, RMON, AAA, ACL, DNS, FTP, SSH, syslog, NTP, RADIUS, SCP, and LLDP. L3 VLAN connectivity Enable L3 VLAN connectivity (VLANs assigned with an IP address) on VLT peers by configuring a VLAN interface for the same VLAN on both devices.
• Configure the same VLT domain ID on peer devices. If a VLT domain ID mismatch occurs on VLT peers, the VLTi does not activate. • In a VLT domain, VLT peers support connections to network devices that connect to only one peer. VLT interconnect A VLTi is the link that synchronizes states between VLT peers. OS10 automatically adds VLTi ports to VLANs spanned across VLT peers. VLTi ports are not supported as members of VLANs configured on only one peer.
RSTP configuration RSTP mode is supported on VLT ports. Before you configure VLT on peer switches, configure RSTP in the network. RSTP prevents loops during the VLT startup phase. • Enable RSTP on each peer node in CONFIGURATION mode.
RPVST+ configuration RPVST+ mode is supported on VLT ports. Before you configure VLT on peer switches, configure RPVST+ in the network. You can use RPVST+ for initial loop prevention during the VLT startup phase. Configure RPVST+ on both the VLT peers. This creates an RPVST+ instance for every VLAN configured in the system. The RPVST+ instances in the primary VLT peer control the VLT LAGs on both the primary and secondary peers. • Enable RPVST+ on each peer node in CONFIGURATION mode.

11 Converged data center services OS10 supports converged data center services, including IEEE 802.1 data center bridging (DCB) extensions to classic Ethernet. DCB provides I/O consolidation in a data center network. Each network device carries multiple traffic classes while ensuring lossless delivery of storage traffic with best-effort for LAN traffic and latency-sensitive scheduling of service traffic. • 802.1Qbb — Priority flow control • 802.1Qaz — Enhanced transmission selection • 802.
PFC configuration notes • PFC is supported for 802.1p priority traffic (dot1p 0 to 7). FCoE traffic traditionally uses dot1p priority 3 — iSCSI storage traffic uses dot1p priority 4. • Configure PFC for ingress traffic by using network-qos class and policy maps (see Quality of Service). The queues used for PFCenabled traffic are treated as lossless queues. Configure the same network-qos policy map on all PFC-enabled ports.
trust dot1p exit 2 Apply the qos trust policy to ingress traffic in SYSTEM-QOS or INTERFACE mode. service-policy input type qos trust-policy—map-name Configure a non-default dot1p-priority-to-traffic class mapping 1 Configure a trust map of dot1p traffic classes in CONFIGURATION mode. A trust map does not modify ingress dot1p values in output flows. Assign a qos-group to trusted dot1p values in TRUST mode using 1-to-1 mappings. Dot1p priorities are 0-7.
Configure PFC Priority flow control (PFC) provides a pause mechanism based on the 802.1p priorities in ingress traffic. PFC prevents frame loss due to network congestion. Configure PFC lossless buffers, and enable pause frames for dot1p traffic on a per-interface basis. Repeat the PFC configuration on each PFC-enabled interface. PFC is disabled by default. Decide if you want to use the default dot1p-priority-to-traffic class mapping and the default traffic-class-to-queue mapping.

pause Configures the ingress buffer and pause frame settings used for PFC traffic classes. Syntax Parameters Defaults pause [buffer-size kilobytes pause-threshold kilobytes resume-threshold kilobytes] • buffer-size kilobytes — Enter the reserved (guaranteed) ingress-buffer size in kilobytes for PFC dot1p traffic (0 to 7787). • pause-threshold kilobytes — Enter the threshold used to send pause frames in kilobytes to a transmitting device (0 to 7787).
Default Not configured Command Mode POLICY-CLASS NETWORK-QOS Usage Information When you enter PFC-enabled dot1p priorities with pfc-cos, the dot1p values must be the same as the match qos-group (traffic class) numbers in the network-qos class map used to define the PFC traffic class (see Configure PFC Example). A qos-group number is used only internally to classify ingress traffic classes.
and link-layer flow control (LLFC) at the same time on an interface. The no version of this command disables PFC on an interface. When you disable PFC, remove the PFC network-qos policy-class map applied to the interface. Example OS10(conf-if-eth1/1/1)# priority-flow-control mode on Supported Releases 10.3.0E or later queue-limit Sets the static and dynamic thresholds used to limit the shared-buffer size of PFC traffic-class queues.

Assign different amounts of bandwidth to traffic classes (Ethernet, FCoE, or iSCSI) that require different bandwidth, latency, and best-effort treatment during network congestion. ETS divides traffic into different priority groups using their 802.
• • • An ETS-enabled interface operates with dynamic weighted round robin (DWRR) or strict priority scheduling. OS10 control traffic is sent to control queues, which have a strict priority that is higher than data traffic queues. ETS-allocated bandwidth is not supported on a strict priority queue. A strict priority queue receives bandwidth only from DCBX TLVs. The CEE/IEEE2.5 versions of ETS TLVs are supported. ETS configurations are received in a TLV from a peer.

DCBX configuration notes • • • • • • • • • To exchange link-level configurations in a converged network, DCBX is a prerequisite for using DCB features, such as PFC and ETS. DCBX is also deployed in topologies that support lossless operation for FCoE or iSCSI traffic. In these scenarios, all network devices must be DCBX-enabled so that DCBX is enabled end-to-end. DCBX uses LLDP to advertise and automatically negotiate the administrative state and PFC/ETS configuration with directly connected DCB peers.

Supported Releases 10.3.0E or later Internet small computer system interface iSCSI is a TCP/IP-based protocol for establishing and managing connections between servers and storage devices in a data center network. After you enable iSCSI, iSCSI optimization automatically detects Dell EqualLogic storage arrays directly attached to switch ports. To support storage arrays where auto-detection is not supported, manually configure iSCSI optimization using the iscsi profilestorage name command.
In an iSCSI session, a switch connects CNA servers (iSCSI initiators) to a storage array (iSCSI targets) in a storage area network (SAN) or TCP/IP network. iSCSI optimization running on the switch uses dot1p priority-queue assignments to ensure that iSCSI traffic receives priority treatment. iSCSI configuration notes • • • • When you enable iSCSI optimization, the switch auto-detects and auto-configures for Dell EqualLogic storage arrays directly connected to an interface.
If you do not configure an iscsi priority-bits dot1p value and you configure a set cos value in Step 6, the set cos value is sent in iSCSI application TLVs. If you configure neither the iscsi priority-bits nor the set cos value, the default dot1p 4 is advertised. iscsi priority-bits dot1p-bitmap 10 Enable iSCSI auto-detection and auto-configuration on the switch in CONFIGURATION mode.

• The default class-trust class map honors dot1p priorities in ingress flows and applies a 1-to-1 dot1p-to-qos-group and a 1-to-1 qosgroup-to-queue mapping. In OS10, qos-group represents a traffic class used only for internal processing. 1. DCBX configuration (global) Configure DCBX globally on a switch to enable the exchange of DCBX TLV messages with PFC, ETS, and iSCSI configurations. OS10# configure terminal OS10(config)# dcbx enable 2.
A trust dot1p-map assigns dot1p 0, 1, 2, and 3 traffic to qos-group 0, and dot1p 4, 5, 6, and 7 traffic to qos-group 1. A qos-map traffic-class map assigns the traffic class in qos-group 0 to queue 0, and qos-group 1 traffic to queue 1. A queuing policy map assigns 30% of interface bandwidth to queue 0, and 70% of bandwidth to queue 1. The pclass policy map applies trust to all dot1p ingress traffic. Trust does not modify ingress dot1p values in output flows.
