Configuring Bridge Group Interfaces

To configure a bridge group interface:

1. From Global Configuration mode, select the ATM, Fast Ethernet, Gigabit Ethernet, or 10-Gigabit Ethernet interface or subinterface that you want to assign to the bridge group.
2. Assign the interface or subinterface to an existing bridge group to create the bridge interface.
3. (Optional) Configure the bridge group interface as a trunk (server) interface.
4. (Optional) Enable SNMP link status processing for the bridge group interface.
5. (Optional) Set the maximum number of dynamic MAC addresses that the bridge group interface can learn.

For detailed sample configurations that include bridge interfaces, see Configuration Examples.

bridge-group

• Use to assign a bridge interface to an existing bridge group.
• To create a subscriber (client) bridge group interface, which is the default, you must supply the alphanumeric name of the bridge group (specified in the bridge command) to which you want to assign the interface.
• Optionally, you can also choose one of the following keywords:
  • subscriber-trunk—Creates a trunk (server) bridge group interface
  • snmp-trap link-status—Enables SNMP link status processing for the specified interface in the specified bridge group; SNMP link status processing is disabled by default
  • learn addressCount—Sets the maximum number of MAC addresses that the bridge group interface can learn, where addressCount is an integer in the range 0–64000. A value of 0 indicates that an individual bridge group interface can learn an unlimited number of MAC addresses, up to the maximum number that the router supports.
• Example 1—Creates a subscriber (client) bridge group interface for a bridge group named westford02 with SNMP link status processing enabled

  host1(config-subif)#bridge-group westford02 snmp-trap link-status

• Example 2—Sets the maximum number of learned MAC addresses on the westford02 bridge interface to 1000

  host1(config-subif)#bridge-group westford02 learn 1000

• Example 3—Creates a trunk (server) interface for a bridge group named westford03

  host1(config-subif)#bridge-group westford03 subscriber-trunk

• Use the no version to remove the interface from the bridge group and to restore the default value for the keyword you specified.
• See bridge-group.

interface atm

• Use to select an ATM interface or subinterface type.
• Example

  host1(config)#interface atm 3/2.1

• Use the no version to remove the interface or subinterface.
• See interface atm.

interface fastEthernet

• Use to select a Fast Ethernet interface.
• Example

  host1(config)#interface fastEthernet 1/0.2

• Use the no version to remove the interface or subinterface. You must issue the no version from the highest level down; you cannot remove an interface or a subinterface if the one above it still exists.
• See interface fastEthernet.

interface gigabitEthernet

interface tenGigabitEthernet

• Use to select a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface.
• Examples

  host1(config)#interface gigabitEthernet 1/0

  host1(config)#interface gigabitEthernet 4/0/1

  host1(config)#interface tenGigabitEthernet 4/0/1

• Use the no version to remove the interface or subinterface. You must issue the no version from the highest level down; you cannot remove an interface or subinterface if the one above it still exists.
• See interface gigabitEthernet.
• See interface tenGigabitEthernet.
