For E120 and E320 routers, use the slot / adapter / port [. subinterface ] format, which includes
an identifier for the bay in which the I/O adapter (IOA) resides. In the software, adapter
0 identifies the right IOA bay (E120 router) and the upper IOA bay (E320 router); adapter
1 identifies the left IOA bay (E120 router) and the lower IOA bay (E320 router). For
example, the following command specifies ATM 1483 subinterface 20 on slot 5, adapter
0, port 0 of an E320 router.
host1(config)# interface atm 5/0/0.20

Configuring Bridged Ethernet
This section shows how to configure IP with PPPoE terminated at the E Series router.
With each step, an illustration shows how the router is building the interface columns.
Configuring IP with PPPoE Terminated at the Router
This section shows how to create IP with PPPoE interfaces that terminate the connection
and route the data received on the PVC, as shown in the example in Figure 43 on page 444.
To create a terminated PVC:
1.
Create an ATM 1483 subinterface and associated PVC.
host1(config)# interface atm 9/1.1 point-to-point
host1(config-subif)# atm pvc 1 0 32 aal5snap 0 0 0
2.
Encapsulate the ATM 1483 subinterface with bridged Ethernet. The use of the
encapsulation keyword implies that the bridged Ethernet interface is the only
interface stacked directly above the ATM 1483 subinterface. As a result, the bridged
Ethernet interface cannot have a peer interface stacked above the same lower-layer
interface.
host1(config-subif)# encapsulation bridge1483
3.
Create a PPPoE major interface over the bridged Ethernet interface. This command
does not use the
encapsulation keyword.
host1(config-subif)# pppoe
