Monitoring MPLS Layer 2 Interfaces for Layer 2 Services over MPLS
Purpose
Display status and configuration information about MPLS layer 2 major, minor, and shim interfaces. Both the show mpls interface shim command and the show mpls l2transport interface command provide the same output. The shim keyword displays all shim interfaces. The brief keyword displays only limited interface information.
Action
To display information about MPLS layer 2 interfaces:
host1#show mpls interface shim
MPLS shim interface FastEthernet2/0
Remote PE address is 10.9.1.3
Virtual circuit ID is 1
Group ID is 0 by default
Control word is not preferred by default
Don't send sequence numbers by default
Relay format is ethernet by default
Administrative state is enabled
Operational state is down (shim interface does not have a next-hop)
Operational MTU is 1500
Received:
0 packets
0 bytes
1 error
0 discards
Sent:
0 packets
0 bytes
0 errors
0 discards
received mtu 0
queue 0: traffic class best-effort, bound to ethernet FastEthernet2/0
Queue length 0 bytes
Forwarded packets 0, bytes 0
Dropped committed packets 0, bytes 0
Dropped conformed packets 0, bytes 0
Dropped exceeded packets 0, bytes 0
MPLS policy input shimRl
classifier-group *
0 packets, 0 bytes

committed: 0 packets, 0 bytes
conformed: 0 packets, 0 bytes
