# Monitoring the Policy Configuration of Layer 2 Services over MPLS

#### Purpose

Display status and configuration information about layer 2 services over MPLS (also known as Martini, or layer 2 transport) on the router or on specific interfaces. Displays only layer 2 circuits for the specified interface.

#### Action

To display information about layer 2 services over MPLS policy lists:

    host1#show mpls l2transport interface
    FastEthernet9/0.1
      routed to 222.9.1.3  on base LSP  tun mpls:lsp-de090100-24-37
      group-id 2 vc-id 900001 mtu 1500
      State UP
      In  Label 48 on stack
        0 pkts, 0 hcPkts, 0 octets
        0 hcOctets, 0 errors, 0 discardPkts

      Out Label 49 on  tun mpls:lsp-de090100-24-37
        0 pkts, 0 hcPkts, 0 octets
        0 hcOctets, 0 errors, 0 discardPkts
        queue 0: traffic class best-effort, bound to atm-vc ATM1/0.1
          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 mplsInputPolicy

            0 packets, 0 bytes

              committed: 0 packets, 0 bytes, action: transmit
              conformed: 0 packets, 0 bytes, action: transmit
              exceeded:  0 packets, 0 bytes, action drop
        MPLS policy output mplsOutputPolicy
          classifier-group claclWst75 entry 1
            0 packets, 0 bytes
            rate-limit-profile rlp
              committed: 0 packets, 0 bytes, action: transmit
              conformed: 0 packets, 0 bytes, action: transmit
              exceeded:  0 packets, 0 bytes, action: drop

#### Meaning

Table 40 lists the show mpls l2transport interface command output fields.

Table 40: show mpls l2transport interface Output Fields

Field Name | Field Description
--- | ---
Interface | Specifier and status of each interface
base-LSP/remote-addr | Identifies either the tunnel that is selected to forward the traffic or the address of the router at the other end
group-id | Group ID number for the interface
vc-id | VC ID number for the interface
mtu | Maximum transmission unit for the interface
state/in/out-label | Status of the Layer 2-over-MPLS connection or the incoming/outgoing VC label
Mpls Statistics |
pkts | Number of packets received or sent
hcPkts | Number of high-capacity (64-bit) packets received or sent
octets | Number of octets received or sent
hcOctets | Number of high-capacity (64-bit) octets received or sent
errors | Number of packets that are dropped for some reason at receipt or before being sent
discardPkts | Number of packets that are discarded due to lack of buffer space at receipt or before being sent
queue, traffic class, bound to | Queue and traffic class bound to the specified interface
Queue length | Number of bytes in queue
Forwarded packets, bytes | Total number of packets and bytes forwarded by this interface
Dropped committed packets, bytes | Total number of committed packets and bytes dropped by this interface
Dropped conformed packets, bytes | Total number of conformed packets and bytes dropped by this interface
Dropped exceeded packets, bytes | Total number of exceeded packets and bytes dropped by this interface
MPLS policy | Type (input, output) and name of policy
classifier-group | Name of a CLACL attached to the interface and number of entry
rate-limit-profile | Name of profile
Committed | Number of packets and bytes conforming to the committed access rate
Conformed | Number of packets and bytes that exceed the committed access rate but conform to the peak access rate
Exceeded | Number of packets and bytes exceeding the peak access rate
