CLI Guide

Link MTU and IP MTU considerations for Port Channels are:
● All members must have the same link MTU value and the same IP MTU value.
● The Port Channel link MTU and IP MTU must be less than or equal to the link MTU and IP MTU values
configured on the channel members. For example, if the members have a link MTU of 2100 and an IP
MTU 2000, the Port Channel’s MTU values cannot be higher than 2100 for link MTU or 2000 bytes for
IP MTU.
When an interface is removed from a Port Channel with the no channel-member command, the
interface reverts to its configuration prior to joining the Port Channel.
An interface can belong to only one Port Channel.
