Specifies that when you enable LACP, this command
enables LACP only if an LACP device is detected.
The interface is in a passive negotiation state, in which
the port responds to LACP packets that it receives
but does not initiate LACP negotiation.

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.
Use the force keyword to force the addition of the interface into the specified channel group.
After you enable LACP globally, by using the feature lacp command, you enable LACP on each channel by
configuring the channel mode as either active or passive. An 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 an EtherChannel, the EtherChannel remains. To delete the EtherChannel
completely, use the no form of the interface port-channel command.
