You can use the show bridge interface command to display information for a specified bridge interface or for all interfaces assigned to a bridge group.

show bridge interface

Use to display configuration, statistics, and status information for a specified bridge interface or for all interfaces assigned to a bridge group.
Field descriptions
- BridgeGroup—Name of the bridge group to which the interface belongs
- Port Number—Bridge group port number on which this interface resides
- Operational Status—Operational status of the physical interface: Up, Down, LowerLayerDown, NotPresent
- Admin Status—State of the physical interface: Up, Down
- Snmp Link Status Trap—Whether SNMP link status processing is enabled or disabled for the specified bridge interface
- Max Learn—Maximum number of dynamic MAC addresses that the bridge group interface can learn
- Subscriber Policy—Name of the subscriber policy currently in effect for the bridge group interface
- Statistics—Displays statistics information for the specified port
  - In Octets—Number of octets received on this interface
  - In Frames—Number of frames received on this interface
  - In Discards—Number of incoming packets discarded on this interface
  - In Errors—Number of incoming errors received on this interface
  - Out Octets—Number of octets transmitted on this interface
  - Out Frames—Number of frames transmitted on this interface
  - Out Discards—Number of outgoing packets discarded on this interface
  - Out Errors—Number of outgoing errors on this interface
- queue—Hardware packet queue associated with the specified traffic class and interface
  - Queue length—Length of the queue, in bytes
  - Forwarded packets, Bytes—Number of packets and bytes forwarded on this queue
  - Dropped committed packets, Bytes—Number of committed packets and bytes that were dropped
  - Dropped conformed packets, Bytes—Number of conformed packets and bytes that were dropped
  - Dropped exceeded packets, Bytes—Number of exceeded packets and bytes that were dropped
- Using the brief keyword displays the following fields:
  - Interface—Interface type and specifier associated with the port (for example, FastEthernet9/1.1)
  - Port—Bridge group port number on which this interface resides
  - Status—Operational status of the physical interface: Up, Down, LowerLayerDown, NotPresent

Example 1—Displays information about a specified interface

host1#show bridge interface fastEthernet 9/1.1
    fastEthernet9/1.1
      BridgeGroup: 1
      Port Number: 1
      Operational Status: Up
      Admin Status: Up
      Snmp Link Status Trap: Disabled
      Max Learn: Unlimited
      Subscriber Policy: atmfe1
      Statistics:
         In Octets:    0
         In Frames:    0
         In Discards:  0
         In Errors:    0
         Out Octets:   0
         Out Frames:   0
         Out Discards: 0
         Out Errors:   0
      queue 0: traffic class best-effort, bound to bridge     FastEthernet9/1.1 
        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

Example 2—Uses the brief keyword to display a summary of all bridge interfaces configured on the router

host1#show bridge westford01 interface brief
Interface            Port       Status
-----------------  --------   ------------
FastEthernet9/1.1     1           Up
FastEthernet9/1.2     2           Up
FastEthernet9/3.1     3           Up
ATM11/0.5             4           Up
ATM11/3.2             5           Up
ATM11/0.7             6           Up
