Configure VLACP Flap Detect and Damping on a Port
About this task
Perform the following procedure to control link state changes on VLACP ports. By default, VLACP Flap Detect and Damping is disabled on all VLACP ports.
Important
Do not enable VLACP Flap Detect and Damping on Link Aggregation Control Protocol (LACP) enabled ports.
Before you begin
-
To configure VLACP Flap Detect and Damping on sub-ports, enable channelization. For more information about channelization, see Channelization.
-
As a best practice, to modify an existing VLACP Flap Detect and Damping configuration, first disable VLACP on the interface.
Procedure
Example
Configure VLACP Flap Detect and Damping on port 1/3:
