Reassign an interface to a new port channel
An interface can be a member of only one port channel. If the interface is a member of a port channel, you
must remove it from the first port channel and then add it to the second port channel.
Each time you add or remove a channel member from a port channel, FTOS recalculates the hash
algorithm for the port channel.
To reassign an interface to a new port channel, use these commands in the following sequence in the
INTERFACE mode of a port channel:
Figure 20-16 displays an example of moving the GigabitEthernet 1/8 interface from port channel 4 to port
channel 3.
