Password: required, neighbor, in use

The Password field might display any of the following for the status of the password:

Required or not required—Indicates whether password configuration is required.

Neighbor, none, option #, or fallback—Indicates the password source when the password was 
configured.

In use (current) or stale (previous)—Indicates the current LDP session password usage status.

Look at the output of the command to verify your configuration.

show mpls ldp neighbor detail

Use this command to verify that the password information for a neighbor is as you configured. For 
example:

Router# show mpls ldp neighbor detail

show mpls ldp neighbor password [pending | current]

Use this command to verify that LDP sessions are using the password configuration that you expect, 
either the same as or different from that in the current configuration. The pending keyword displays 
information for LDP sessions whose password is different from that in the current configuration. The 
current keyword displays information for LDP sessions whose password is the same as that in the 
current configuration.
