Port Channel Commands
A Link Aggregation Group (LAG) is a group of links that appear to a MAC client as if they were a
single link according to IEEE 802.3ad. In FTOS, a LAG is referred to as a Port Channel.
Table 24-12. Port Channel Limits
Because each port can be assigned to only one Port Channel, and each Port Channel must have at least
one port, some of those nominally available Port Channels might have no function because they could
have no members if there are not enough ports installed. In the S-Series, those ports could be provided
by stack members.
The commands in this section are specific to Port Channel interfaces:
• channel-member
• group
• interface port-channel
• minimum-links
• port-channel failover-group
• show config
• show interfaces port-channel
• show port-channel-flow
channel-member
c e s
Add an interface to the Port Channel, while in the INTERFACE PORTCHANNEL mode.
Syntax

To delete an interface from a Port Channel, use the no channel-member interface command.

Note: The FTOS implementation of LAG or Port Channel requires that you configure a LAG
on both switches manually. For information on FTOS Link Aggregation Control Protocol
(LACP) for dynamic LAGs, refer to Chapter 30, Link Aggregation Control Protocol (LACP).
For more information on configuring and using Port Channels, refer to the FTOS
Configuration Guide.
