Removing Ports from an Dynamic LACP Trunk Group. To remove a
port from dynamic LACP trunk operation, you must turn off LACP on the port.
(On a port in an operating, dynamic LACP trunk, you cannot change between
LACP Active and LACP passive without first removing LACP operation from
the port.)
Unless STP is running on your network, removing a port from a trunk can
result in a loop. To help prevent a broadcast storm when you remove a port
from a trunk where STP is not in use, HP recommends that you first disable
the port or disconnect the link on that port.
Syntax: no interface <port-list> lacp
In this example, port C6 belongs to an operating, dynamic LACP trunk. To
remove port C6 from the dynamic trunk and return it to passive LACP, you
would do the following:
HPswitch>(config)# no interface c6 lacp
HPswitch>(config)# interface c6 lacp passive
Note that in the above example, if the port on the other end of the link is
configured for active LACP or static LACP, the trunked link will be re-
established almost immediately.
