Platform Considerations

You can configure bridged Ethernet on the following E Series Broadband Services Routers:

Interface Specifiers

The configuration task examples in this chapter use the slot/port[.subinterface ] format to specify the ATM physical interface on which you want to configure bridged Ethernet. However, the interface specifier format that you use depends on the router that you are using.

For ERX7xx models, ERX14xx models, and ERX310 router, use the slot/port[.subinterface ] format. For example, the following command specifies ATM 1483 subinterface 10 on slot 0, port 1 of an ERX7xx model, ERX14xx model, or ERX310 router.

host1(config)#interface atm 0/1.10

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
