About PortChannel Deletion

When you delete the PortChannel, the corresponding channel membership is also deleted. All interfaces
in the deleted PortChannel convert to individual physical links. After the PortChannel is removed,
regardless of the mode used (ACTIVE and ON), the ports at either end are gracefully brought down,
indicating that no frames are lost when the interface is going down (see the
on page
If you delete the PortChannel for one port, then the individual ports within the deleted PortChannel
retain the compatibility parameter settings (speed, mode, port VSAN, allowed VSAN, and port security).
You can explicitly change those settings as required.

Deleting PortChannels

To delete a PortChannel, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# no interface port-channel 1
port-channel 1 deleted and all its members
disabled
please do the same operation on the switch at the
other end of the port-channel
switch(config)#
Interfaces in a PortChannel
You can add or remove a physical interface (or a range of interfaces) to an existing PortChannel. The
compatible parameters on the configuration are mapped to the PortChannel. Adding an interface to a
PortChannel increases the channel size and bandwidth of the PortChannel. Removing an interface from
a PortChannel decreases the channel size and bandwidth of the PortChannel.
This section describes interface configuration for a PortChannel and includes the following topics:

If you use the default ON mode to avoid inconsistent states across switches and to maintain
consistency across switches, then the ports shut down. You must explicitly enable those ports again.
If you use the ACTIVE mode, then the PortChannel ports automatically recover from the deletion.
