Usage Guidelines Use this command to create a channel group that includes the interface that you are working on and to
add or remove specific interfaces from the channel group. Use this command to move a port from one
channel group to another. You enter the channel group that you want the port to move to; the switch
automatically removes the specified port from its present channel group and adds it to the specified
channel group.
After you enable LACP globally, by using the
by configuring the channel mode as either active or passive. A EtherChannel in the on channel mode is
a pure EtherChannel and can aggregate a maximum of eight ports. The EtherChannel does not run LACP.
You cannot change the mode for an existing EtherChannel or any of its interfaces if that EtherChannel
is not running LACP; the channel mode remains as on. The system returns an error message if you
attempt to change the mode.
Use the no form of this command to remove the physical interface from the EtherChannel. When you
delete the last physical interface from a EtherChannel, the EtherChannel remains. To delete the
EtherChannel completely, use the no form of the interface port-channel command.
The compatibility check includes the following operational attributes:

Use the show port-channel compatibility-parameters command to see the full list of compatibility
checks that Cisco NX-OS uses.
You can only add interfaces configured with the channel mode set to on for static EtherChannels, that
is, without a configured aggregation protocol. You can only add interfaces configured with the channel
mode as active or passive to EtherChannels that are running LACP.
You can configure these attributes on an individual member port. If you configure a member port with
an incompatible attribute, Cisco NX-OS suspends that port in the EtherChannel.
When the interface joins a EtherChannel, some of its individual parameters are overridden with the
values on the EtherChannel, as follows:
•
•
•
•
•
Interface parameters, such as the following, remain unaffected when the interface joins or leaves a
EtherChannel:
•
•
