Displaying LDP Protocol Counters

LDP control protocol packet error counters are maintained per interface.
To view these counters, use the following command:
show mpls ldp interface {{vlan} vlan_name} {detail | counters}

These counters may be useful in determining LDP issues between peers.

Error counters that continually increment should be investigated.
