cdp enable

Prime Optical issues the following command when you disable CDP on a selected drop:

If a problem arises during the initial synchronization, you can resynchronize the Layer 2 topology by 
choosing Configuration > Resync L2 Topology in the Layer 2 Topology table (see 

).

This feature only restarts the L2 topology resynchronization state. It does not forcefully apply any 
configuration on the ML-series card to complete the synchronization of the L2 topology.

Alternative methods of resynchronization are:

Mark the NEs participating in the L2 topology as Out of Service, and then In Service.

Restart the NE service. 

Although effective, these methods cause a time lag that affects other functions, such as inventory 
collection and circuit discovery.
