switch(config)# interface port-channel 1
switch(config-if)#
Step 3
switch(config-if)# channel mode active
switch(config-if)# no channel mode active
Deleting PortChannels
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 (ACTIVE and ON) used, the ports at either end are gracefully brought down,
indicating that no frames are lost when the interface is going down (see the
section 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.

To delete a PortChannel, follow these steps:
Command
Step 1
switch# config t
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)#
Interface Addition to a PortChannel
You can add a physical interface (or a range of interfaces) to a nonexistent or an existing PortChannel
and the PortChannel is automatically created. If the PortChannel does not exist, it is created. 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.
After the members are added, regardless of the mode (ACTIVE and ON) used, the ports at either end are
gracefully brought down, indicating that no frames are lost when the interface is going down (see the
"Graceful Shut Down" section on page
Cisco MDS 9000 Family Configuration Guide

11-9).
If you use the default ON mode, to avoid inconsistent states across switches, and to maintain
consistency across switches, the ports shut down. You must explicitly enable those ports again.
If you use the ACTIVE mode, the PortChannel ports automatically recover from the deletion.
Purpose
Enters configuration mode.
Configures the specified PortChannel (1) using the
default ON mode.
Configures the ACTIVE mode.
Reverts to the default ON mode.
Purpose
Enters configuration mode.

associated interface mappings, and the
hardware associations for this PortChannel.
