Configuring a Dynamic Bridged Ethernet Interface

554
When bridged Ethernet packets are received over ATM circuits, the bridged Ethernet and
IP interfaces are dynamically constructed over the corresponding ATM 1483 interfaces
and use the configuration data received from the RADIUS server, a profile, or both.
Figure 55 on page 554 shows the protocol layers that represent the bridged Ethernet
interface columns, and the layers within the interface columns that are static and dynamic.

Columns
When you configure dynamic bridged Ethernet interfaces, you must assign a profile. You
may optionally assign a subscriber identification.
To configure dynamic bridged Ethernet interfaces:
Configure a physical interface.
1.
host1(config)#interface atm 5/0
Configure an ATM subinterface.
2.
host1(config-if)#interface atm 2/0.1
Configure a PVC by specifying the VCD, the VPI, the VCI, and the encapsulation type.
3.
If you want the router to autodetect the encapsulation type, use the aal5autoconfig
option.
host1(config-subif)#atm pvc 10 100 22 aal5snap
host1(config-subif)#atm pvc 10 100 22 aal5autoconfig
Do either of the following:
4.
Configure the subinterface to detect and accept the dynamic bridged Ethernet
encapsulation type with the default lockout time range, 1–300 seconds.
host1(config-subif)#auto-configure bridgedEthernet
Configure the subinterface to detect and accept the dynamic bridged Ethernet
encapsulation type with a nondefault lockout time range. For example, the
