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.
Automatic installation You can automatically (zero-touch) install an OS10 image on a Dell ONIE-enabled device. Once the device successfully boots to ONIE: Install OS, auto-discovery obtains the hostname, domain name, Management interface IP address, as well as the IP address of the DNS name server(s) on your network from the DHCP server and DHCP options. The ONIE automatic-discovery process locates the stored software image, starts installation, then reboots the device with the new software image.
The ONIE auto-discovery process discovers the image file at the specified USB path, loads the software image, and reboots. Log into OS10 To log in to OS10 Enterprise Edition, power up the device and wait for the system to perform a power-on self test (POST). Enter admin for both the default user name and user password. For better security, change the default admin password during the first OS10 login. The system saves the new password for future logins.
Install license OS10# license install scp://user:userpwd@10.1.1.10/CFNNX42-NOSEnterprise-License.xml License installation success. Verify license installation OS10# show license status System Information -----------------------------------------Vendor Name : DELL Product Name : S4048-ON Hardware Version: A00 Platform Name : S4048-ON PPID : CN0M68YC2829855M0133 Service Tag : CFNNX42 License Details ---------------Software : OS10-Enterprise Version : 10.3.
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. 1 Configure the management interface from CONFIGURATION mode. interface mgmt node/slot/port 2 Configure an IPv4 or IPv6 address on the Management interface in INTERFACE mode. ip address A.B.C.D/mask ipv6 address A:B/prefix-length 3 Enable the Management interface in INTERFACE mode.
Configure user name and password To set up remote access to OS10, create a new user name and password after you configure the management port and default route. The user role is a mandatory entry. Enter the password in clear text. It is converted to SHA-512 format in the running configuration. A password must have at least nine alphanumeric and special characters, and at least five different characters from the password previously used for the same username. For backward compatibility with OS10 releases 10.
User accounts OS10 defines two categories of user accounts — use admin for both the username and password to log into the CLI, or use linuxadmin to log into the Linux shell. Key CLI features Consistent command names Commands that provide the same type of function have the same name, regardless of the portion of the system on which they are operating. For example, all show commands display software information and statistics, and all clear commands erase various types of system information.
CLI command hierarchy CLI commands are organized in a hierarchy. Commands that perform a similar function are grouped together under the same level of hierarchy. For example, all commands that display information about the system and the system software are grouped under the show system command, and all commands that display information about the routing table are grouped under the show route-map command.
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 VLANs in L2 or L3 modes. Table 1.
Figure 1. S4148U-ON unified port groups To enable Ethernet interfaces in a unified port group: 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 Ethernet operation in PORT-GROUP mode. mode Eth {100g-1x | 50g-2x | 40g-1x | 25g-4x | 10g-4x} • • • • • 10g-4x — Split a QSFP28 or QSFP+ port into four 10G interfaces. 25g-4x — Split a QSFP28 port into four 25G interfaces.
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. By default, a trunk port is not added to any tagged VLAN. You must create a VLAN before you can assign the interface to it.
Figure 2. 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.

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, VLAN 1 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 spanning-tree protocols.
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 Port Channel IP Address You can assign an IP address to a port channel and use port channels in L3 routing protocols. • Configure an IP address and mask on the interface in INTERFACE mode. ip address ip-address mask [secondary] • ip-address mask — Specify an IP address in dotted-decimal format (A.B.C.D) and the mask in slash format (/24).
• tcp-upd-selection [l4–destination-port | l4–source-port] — Uses the Layer 4 destination IP address, or Layer 4 source IP address in the hash calculation. • ip-selection [destination-ip | source-ip | protocol | vlan-id | l4–destination-port | l4– source-port] — Uses the destination IP address, source IP address, protocol, VLAN ID, Layer 4 destination IP address, or Layer 4 source IP address in the hash calculation.

In the port profile illustration, blue boxes indicate the supported ports and breakout interfaces.
S4148U-ON port profiles S4148U-ON port profiles determine the available front-panel unified and Ethernet ports and supported breakout interfaces. In the port profile illustration, blue boxes indicate the supported Ethernet port modes and breakout interfaces. Brown boxes indicate the supported Fibre Channel port modes and breakout interfaces. Blank spaces indicate ports and speeds that are not available. Unified port groups are numbered 1–10.
**Oversubscription: Configure oversubscription to support bursty storage traffic on a Fibre Channel interface. Oversubscription allows a port to operate faster, but may result in traffic loss. To support oversubscription, use the speed command in Interface configuration mode. This command is not supported on an Ethernet interface. In S4148U-ON port profiles: • SFP+ and QSFP28 port groups in 4x8GFC mode support 16GFC oversubscription on member interfaces.
Breakout auto-configuration You can globally enable front-panel Ethernet ports to automatically detect SFP pluggable media in a QSFP+ or QSFP28 port. The port autoconfigures breakout interfaces for media type and speed. For example, if you plug a 40G DAC cable with 4x10G far-side transceivers into a QSFP28 port, the port autoconfigures in 10g-4x Interface-breakout mode. enable auto-breakout RJ-45 ports and ports that are members of a port group do not support breakout auto-configuration.

An Ethernet link consumes power when a link is idle. EEE allows for Ethernet links to use the regular power mode only during data transmission. EEE is enabled on devices that support LOW POWER IDLE (LPI) mode. Such devices can save power by entering LPI mode during periods when no data is transmitted. In LPI mode, systems on both ends of the link saves power by shutting down certain services. EEE transitions into and out of LPI mode transparently to upper-layer protocols and applications.

Zoning allows you to increase network security by partitioning the devices connected to the vfabric into subsets. Partitioning restricts unnecessary interactions between the members of vfabric. See also Fibre Channel zoning. After configuring a vfabric ID, you can create a name, associate a VLAN to carry traffic to the vfabric, configure FCoE parameters, configure the default zone, and activate the zoneset. NOTE: Do not associate a VLAN that is already in use, as a vfabric VLAN.

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.

Link aggregation control protocol Group Ethernet interfaces to form a single link layer interface called a LAG or port-channel. 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.
path to reach a router external to the AS. EBGP routers exchange information with other EBGP routers and IBGP routers to maintain connectivity and accessibility. 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.
Established Keepalive messages exchange, and after a successful receipt, the router is in the Established state. Keepalive messages continue to send at regular periods. The keepalive timer establishes the state to verify connections. 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.
Multiprotocol BGP Multiprotocol BGP (MBGP) is an extension to BGP that supports multiple address families—IPv4 and IPv6. MBGP carries multiple sets of unicast and multicast routes depending on the address family. You can enable the MBGP feature on a per router, per template, and/or a per peer basis. The default is the IPv4 unicast routes.
• A path with no AS_PATH configured has a path length of 0 • AS_CONFED_SET is not included in the AS_PATH length • AS_CONFED_SEQUENCE has a path length of 1 no matter how many ASs are in the AS_CONFED_SEQUENCE 4 Prefer the path with the lowest ORIGIN type—IGP is lower than EGP and EGP is lower than INCOMPLETE. 5 Prefer the path with the lowest multiexit discriminator (MED) attribute: • This comparison is only done if the first neighboring AS is the same in the two paths.
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.
The question mark (?) indicates an origin code of INCOMPLETE, and the lower case letter (i) indicates an origin code of IGP. Origin configuration OS10# show ip bgp BGP local RIB : Routes to be Added , Replaced , Withdrawn BGP local router ID is 30.1.1.
If you configure the bgp bestpath as-path ignore command and the bestpath as-path multipath-relax command at the same time, an error message displays—only enable one command at a time. 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.
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.

! neighbor 32.1.1.2 remote-as 104 no shutdown ! address-family ipv4 unicast Confederations Another way to organize routers within an AS and reduce the mesh for IBGP peers is to configure BGP confederations. 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.

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.

When you disable fast-convergence, origination and arrival LSA parameters are set to 0 msec and 1000 msec, respectively. Setting the convergence parameter from 1 to 4 indicates the actual convergence level. Each convergence setting adjusts the LSA parameters to zero, but the convergence-level parameter changes the convergence speed. The higher the number, the faster the convergence. • Enable OSPFv2 fast-convergence and enter the convergence level in ROUTER-OSPF mode from 1 to 4.
5 Change the priority of the interface, which determines the DR for the OSPF broadcast network in INTERFACE mode, from 0 to 255. The default priority of the interface is 1. ip ospf priority number 6 Change the retransmission interval time, in seconds, between LSAs in INTERFACE mode, from 1 to 3600.

Interface OSPFv3 Parameters Interface parameter values must be consistent across all interfaces to avoid routing errors. For example, set the same time interval for the hello packets on all routers in the OSPF network to prevent misconfiguration of OSPF neighbors. 1 Enter the interface to change the OSPFv3 parameters in CONFIGURATION mode. interface interface-name 2 Change the cost associated with OSPFv3 traffic on the interface in INTERFACE mode (1 to 65535, default depends on the interface speed).
OSPFv3 IPsec authentication and encryption Unlike OSPFv2, OSPFv3 does not have authentication fields in its protocol header to provide security. To provide authentication and confidentiality, OSPFv3 uses IP Security (IPsec) — a collection of security protocols for authenticating and encrypting data packets. OS10 OSPFv3 supports IPsec using the IPv6 authentication header (AH) or IPv6 encapsulating security payload (ESP).

timers spf (OSPFv3) Enables shortest path first (SPF) throttling to delay an SPF calculation when a topology change occurs. Syntax Parameters Default timers spf [start-time [hold-time [max-wait]]] • start-time — Sets the initial SPF delay in milliseconds (1 to 600000; default 1000). • hold-time — Sets the additional hold time between two SPF calculations in milliseconds (1 to 600000; default 10000).
a tracked object changes state. You can also optionally specify a time delay before changes in a tracked object's state are reported to a client application. VRRP can subscribe to a track object which tracks the interface line protocol state. It can use the tracked object status to determine the priority of the VRRP router in a VRRP group. If a tracked state, or interface goes down, VRRP updates the priority based on what you configure the new priority to be for the tracked state.
When the link-level status goes down, the tracked resource status is also considered Down. If the link-level status goes up, the tracked resource status is also considered Up. For logical interfaces (port-channels or VLANs), the link-protocol status is considered to be Up if any physical interface under the logical interface is Up.

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.

Example OS10(conf-eth1/1/6-vrid-250)# advertise-interval 120 centisecs 100 Supported Releases 10.2.0E or later authentication-type Enables authentication of VRRP data exchanges. Syntax Parameters authentication-type simple-text password [auth-text] • simple-text password — Enter a simple text password. • auth-text — (Optional) Enter a character string up to eight characters long as a password.
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.
Configure UFT modes Available UFT modes include L2 MAC table, L3 host table, or L3 route table sizes. • Select a mode to initialize the maximum table size in CONFIGURATION mode. hardware forwarding-table mode [scaled-l2 | scaled-l3-routes | scaled-l3-hosts] • Disable UFT mode in CONFIGURATION mode.

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.
Ingress and egress hot-lock ACLs allow you to append or delete new rules into an existing ACL without disrupting traffic flow. Existing entries in the CAM shuffle to accommodate the new entries. Hot-lock ACLs are enabled by default and support ACLs on all platforms. NOTE: Hot-lock ACLs support ingress ACLs only. MAC ACLs MAC ACLs filter traffic on the Layer 2 (L2) header of a packet.
Permit all packets on interface OS10(config)# ip access-list ABC OS10(conf-ipv4-acl)# permit ip any 10.1.1.1/32 OS10(conf-ipv4-acl)# deny ip any 10.1.1.1/32 fragments 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.
Assign sequence number to filter IP ACLs filter on source and destination IP addresses, IP host addresses, TCP addresses, TCP host addresses, UDP addresses, and UDP host addresses. Traffic passes through the filter by filter sequence. Configure the IP ACL by first entering IP ACCESS-LIST mode and then assigning a sequence number to the filter. User-provided sequence number • Enter IP ACCESS LIST mode by creating an IP ACL in CONFIGURATION mode.
• Egress L2 ACL Table 5. 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.
View route-map configuration OS10(conf-router-bgp-neighbor-af)# do show route-map route-map test1, deny, sequence 10 Match clauses: ip address prefix-list p1 Set clauses: route-map test2, permit, sequence 10 Match clauses: ip address prefix-list p1 Set clauses: route-map test3, deny, sequence 10 Match clauses: ip address prefix-list p2 Set clauses: route-map test4, permit, sequence 10 Match clauses: ip address prefix-list p2 Set clauses: Match routes Configure match criterion for a route-map.

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 type(default)—Classifies the ingress data traffic. • queuing type—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 type—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 You can classify the ingress traffic based on data traffic or on 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. OS10# show qos maps type trust-map-dot1p dot1p-trust-map DOT1P Priority to Traffic-Class Map : dot1p-trust-map Traffic-Class DOT1P Priority ------------------------------- 4 3 0-4 5 5-7 Apply the map on a specific interface or on system-qos (global) level.
DSCP values TC id Color 60-62 7 Y 63 7 R User–defined DCSP trust map You can override the default mapping by creating 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.
• 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. You can classify the traffic flows based on QoS specific fields or generic fields, using IP or MAC ACLs. Create class-map template to match the fields.
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.
By default CoPP traffic towards the CPU is classified into different queues as shown in the following table. The protocols are listed in the order of low to high priority.
• cir committed-rate—Enter a committed rate value in pps (0 to 4000000). • pir peak rate — Enter a peak-rate value in pps (0 to 40000000).

Shaping traffic You can configure to shape the rate of egress traffic. When you enable rate shaping, the system buffers all traffic exceeding the specified rate till buffer memory is exhausted. The rate shaping mechanism uses all buffers reserved for an interface or queue and then shared buffer memory, till it reaches the configured threshold. Configure traffic shaping 1 Enter the policy-map type as queuing and configure a policy-map name in CONFIGURATION mode.

Storm control Traffic storms created by packet flooding or other reasons may degrade the performance of the network. The storm control feature allows you to control unknown unicast, multicast, and broadcast traffic on Layer 2 and Layer 3 physical interfaces. OS10 device monitors the current level of traffic rate at fixed intervals, compares the traffic rate with configured levels, and drops excess traffic. By default, storm control is disabled on all interfaces.

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.
• In a VLT domain, the peer network devices must run the same OS10 software version. • 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.
RSTP configuration Only 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.
1 Configure a VLT domain and enter VLT-DOMAIN mode. Configure the same VLT domain ID on each peer, from 1 to 255. vlt-domain domain-id 2 Repeat the steps on the VLT peer to create the VLT domain.

VLT unicast routing is supported for IPv4 and IPv6. To enable VLT unicast routing, both VLT peers must be in L3 mode.
Configure VRRP active-active mode — peer 1 OS10(conf-if-vl-10)# vrrp mode active-active Configure VRRP active-active mode — peer 2 OS10(conf-if-vl-10)# vrrp mode active-active View VRRP configuration OS10# show running-configuration interface vlan 10 ! interface vlan10 no shutdown no vrrp mode active-active OS10# Migrate VMs across data centers OS10 does not support proxy gateway. Instead of proxy gateway, you can use VRRP in access VLAN to migrate virtual machines across data centers.
When a virtual machine running in Server Rack 1 migrates to Server Rack 2, L3 packets for that VM are routed through the default gateway. The following examples show sample configurations of the core routers.

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.
1 Create a network-qos class map to classify PFC traffic classes in CONFIGURATION mode (0 to 7). Specify the traffic classes using the match qos-group command.

DCBX uses LLDP to mediate the automatic negotiation and exchange of device settings, such as PFC and ETS. DCBX uses LLDP TLVs to perform DCB parameter exchange: • PFC configuration and application priority configuration • ETS configuration and ETS recommendation This sample DCBX topology shows two 40GbE ports on a switch that are configured as DCBX auto-upstream ports and used as uplinks to top-of-rack (ToR) switches. The top-of-rack (ToR) switches are part of a fibre channel storage network.
Configure DCBX DCBX allows data center devices to advertise and exchange configuration settings with directly connected peers using LLDP. LLDP is enabled by default. To ensure the consistent and efficient operation of a converged data center network, DCBX detects peer misconfiguration. DCBX is disabled at a global level and enabled at an interface level by default. For DCBX to be operational, DCBX must be enabled at both the global and interface levels.

Links are monitored in 15-second intervals for three consecutive instances. Any deviation within that time sends syslog and an alarm event generates. When the deviation clears, another syslog sends and a clear alarm event generates. Link-bundle utilization is calculated as the total bandwidth of all links divided by the total bytes-per-second of all links. If you enable monitoring, the utilization calculation performs when the utilization of the link-bundle (not a link within a bundle) exceeds 60%.
