Congure 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.
Loopback interfaces
A loopback interface is a virtual interface in which the software emulates an interface. Because a loopback interface is not associated to
physical hardware entities, the loopback interface status is not aected by hardware status changes.
Packets routed to a loopback interface are processed locally to the OS10 device. Because this interface is not a physical interface, you can
congure routing protocols on this interface to provide protocol stability. You can place loopback interfaces in default L3 mode.
• Enter the loopback interface number in CONFIGURATION mode (0 to 16383).

Port-channel interfaces
Port-channels are not congured by default. Link aggregation is a method of grouping multiple physical interfaces into a single logical
interface — a link aggregation group (LAG) or port -channel. A port-channel aggregates the bandwidth of member links, provides
redundancy, and load balances trac. If a member port fails, the OS10 device redirects trac to the remaining ports.
A physical interface can belong to only one port-channel at a time, and a port-channel must contain interfaces of the same interface type
and speed. OS10 supports up to 128 port-channels, with up to 16 10G or 40G ports per channel.
To congure a port-channel, use the same conguration commands as for Ethernet port interfaces. Port-channels are transparent to
network congurations and managed as a single interface. For example, congure one IP address for the group, and use the IP address for
all routed trac on the port-channel.
By conguring port channels, you can create larger capacity interfaces by aggregating a group of lower speed links. For example, you can
build a 50G interface by aggregating ve 10G Ethernet interfaces together — if one of the ve interfaces fails, trac is redistributed across
the four remaining interfaces.
