          queue 0: traffic class best-effort, bound to bridge ATM3/1.10
            Queue length 0 bytes
            Forwarded packets 14, bytes 2238

To display information about all interfaces in a VPLS instance, including the VPLS virtual core interface (vplsB):

    host1#show bridge vplsB interface

          Admin Status: Up
          Snmp Link Status Trap: Disabled
          Max Learn: Unlimited
          Subscriber Policy: samplepolicy
          Statistics:
             In Octets:    3770
             In Frames:    27
             In Discards:  0
             In Errors:    0
             Out Octets:   3682
             Out Frames:   27
             Out Discards: 0
             Out Errors:   0
          Time since counters last reset: 01:07:08

          queue 0: traffic class best-effort, bound to bridge FastEthernet1/1.1
            Queue length 0 bytes
            Forwarded packets 27, bytes 3898
            Dropped committed packets 0, bytes 0
            Dropped conformed packets 0, bytes 0
            Dropped exceeded packets 0, bytes 0

        vpls vplsB
          Port Number: 2
          Operational Status: Down
          Admin Status: Up
          Snmp Link Status Trap: Disabled
          Max Learn: Unlimited
          Subscriber Policy: default Trunk
          Statistics:
             In Octets:    0
             In Frames:    0
             In Discards:  0
             In Errors:    0

             Out Errors:   0
          Time since counters last reset: 01:04:10

To display a summary of all interfaces configured for the specified VPLS instance:

    host1#show bridge vplsB interface brief
            Interface            Port       Status
    -------------------------   ------   ------------
    FastEthernet1/1.1           1        Up
    ATM10/1.1.1                 2        Up
    vpls vplsB                  3        Up
