Configuring a Dynamic Bridged Ethernet Interface

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.
host1(config)#interface atm 5/0
Configure an ATM subinterface.
host1(config-if)#interface atm 5/0.1
Configure a PVC by specifying the VCD, the VPI, the VCI, and the encapsulation type. For more information, see Creating a PVC on an ATM 1483 Subinterface.
host1(config-subif)#atm pvc 10 10 22 aal5snap
If you want the router to autodetect the encapsulation type, use the aal5autoconfig option.
host1(config-subif)#atm pvc 10 10 22 aal5autoconfig
Do either of the following:
- Configure the subinterface to detect and accept the dynamic bridged Ethernet encapsulation type with the default lockout time range, 1–300 seconds. For more information, see Configuring a Dynamic Interface over an ATM 1483 Subinterface.
  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 following command configures 3600 seconds (1 hour) as the minimum lockout time and 7200 seconds (2 hours) as the maximum lockout time.
  host1(config-subif)#auto-configure bridgedEthernet lockout-time 3600 7200
Assign a profile to match the encapsulation type of bridged Ethernet. For more information, see Dynamic Interface Configuration Using a Profile.
host1(config-subif)#profile bridgedEthernet foo
(Optional) Assign subscriber identification. For more information, see Configuring a Local Subscriber for a Dynamic IPoA or Bridged Ethernet Interface.
host1(config-subif)#subscriber bridgedEthernet user charlie domain myisp password lucy

(Optional) Verify your configuration.
