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.
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 in a predictable order based on the port ID, instead of in the order in
which 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.
