Creating Bridge Interfaces

On an E-series device, you can create bridge interfaces over an ATM 1483 subinterface, an Fast Ethernet interface, or a Gigabit Ethernet interface. The procedure for creating bridge interfaces is basically the same regardless of what interface you create them on.

NOTE: Before creating a bridge interface using the NMC-RX application, you must create a bridge group using the CLI.

To create a bridge interface on an ATM 1483 subinterface:

1. In the Device-wide Explorer, select Bridged IP (RFC 1483), right-click, and select List All.
2. In the list area, select the Bridged IP (RFC 1483) subinterface you want, right-click, select Create, and click Bridge Interface.

The Create Bridge Interface dialog box appears.

3. Set the bridge interface parameters (Table 62).

 Table 62:   Bridge Interface Parameters  

 Field 
 Description

 Name

 Identifies the interface; generated automatically; cannot edit


 IfIndex

 Identifies the interface on the particular line interface; generated automatically; cannot edit


 Operational

 Current operational status of the interface; cannot edit


 Administrative

 Desired status of the interface: Up/Down; default: Up


 Bridge Group Name

 Click 
 to select a bridge group from the Associate Bridge Group dialog box. See Related Dialog Box.


 Subscriber-Trunk

 Enables subscriber-trunk mode; default: unselected


 Max Learned MAC Addresses

 Maximum number of learned MAC addresses; 0 indicates that there is no limit; range 0-64000; default 0



 

4. Click OK.

The bridge interface is created.

NOTE: Bridge interfaces appear in the Instance Explorer only when created on a Fast Ethernet or a Gigabit Ethernet interface. To list all bridge interfaces on a system, double-click Bridge Interface in the Device-wide Explorer.
