Port-channel interfaces

Port-channels are not congured by default. Link aggregation (LA) 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. A port-channel must contain interfaces of the same interface type and

speed. OS10 supports a maximum of 128 port-channels, with up to thirty-two ports per channel.

To congure a port-channel, use the same conguration commands as the Ethernet port interfaces. Port-channels are transparent to

network congurations and manage 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 40G interface by aggregating four 10G Ethernet interfaces together. If one of the four interfaces fails, trac redistributes across the

three remaining interfaces.

Static

Port-channels are statically congured.

Dynamic Port-channels are dynamically congured using Link Aggregation Control Protocol (LACP).

Member ports of a LAG are added and programmed into the hardware based on the port ID, instead of the order the ports come up. Load

balancing yields predictable results across resets and reloads.

Create port-channel

You can create up to 128 port-channels, with up to 16 port members per group. Congure a port-channel similarly to a physical interface —

you can enable or congure protocols, or assign access control lists (ACLs) to a port channel. After you enable the port-channel, you can

place it in L2 or L3 mode.

To place the port-channel in L2 mode or congure an IP address to place the port-channel in L3 mode, use the switchport command.

1 Create a port-channel in CONFIGURATION mode.

interface port-channel id-number

2 Ensure that the port-channel is active in PORT-CHANNEL mode.
