If you misconfigure PortChannels, you may receive a misconfiguration message. If you receive this
message, the PortChannel's physical links are disabled because an error has been detected.
A PortChannel error is detected if the following requirements are not met:
•
•
•
If all three conditions are not met, the faulty link is disabled.
Enter the show interface command for that interface to verify that the PortChannel is functioning as
required.

Creating a PortChannel

To create a PortChannel, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# interface port-channel 1
switch(config-if)#

Configuring the PortChannel Mode

By default, the CLI and the Device Manager create the PortChannel in ON mode in the NPIV core
switches and ACTIVE mode on the NPV switches. The Fabric Manager creates all PortChannels in
ACTIVE mode. We recommend that you create PortChannels in ACTIVE mode. An F PortChannel is
supported only on ACTIVE mode.
To configure ACTIVE mode, follow these steps:
Command
Step 1
switch# config t
switch(config)#
Step 2
switch(config)# interface port-channel 1
switch(config-if)#
Step 3
switch(config-if)# channel mode active
switch(config-if)# no channel mode active

Each switch on either side of a PortChannel must be connected to the same number of interfaces.
Each interface must be connected to a corresponding interface on the other side (see
an example of an invalid configuration).
Links in a PortChannel cannot be changed after the PortChannel is configured. If you change the
links after the PortChannel is configured, be sure to reconnect the links to interfaces within the
PortChannel and reenable the links.
