Parameters
group-id: Specifies the smart link group ID in the range of 1 to 48.
Usage guidelines
Before configuring the collaboration between a port and the CC function of CFD, make sure that the port
is already a member port of a smart link group.
The control VLAN of the smart link group to which the port belongs must match the detection VLAN of the
CC function of CFD.
Examples
# Configure the collaboration between GigabitEthernet 3/0/1, the primary port of smart link group 1,
and the CC function of CFD to detect the link status.

preemption delay
Use preemption delay to set the preemption delay. When role preemption is enabled, and after the
preemption delay is set, the primary port waits for a specific period before taking over in order to
collaborate with the switchover of upstream devices.
Use undo preemption delay to restore the default.
