Platform Considerations

You can configure POS interfaces 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 a POS interface. 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 a POS interface on slot 0, port 1 of an ERX7xx model, ERX14xx model, or ERX310 router.

host1(config)#interface pos 0/1

For E120 and E320 routers, use the slot/adapter/port 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 a POS interface on slot 5, adapter 0, port 0 of an E320 router.

host1(config)#interface pos 5/0/0
