The configuration task examples in this chapter use the format for ERX-7xx models, ERX-14xx models, and the ERX-310 router to specify an Ethernet interface. (The format is described in Numbering Scheme .)
For example, the following command specifies a Fast Ethernet interface on port 0 of an I/O module in slot 4.
- host1(config)#interface fastEthernet 4/0
When you configure a Gigabit Ethernet interface or a 10-Gigabit Ethernet interface on E120 or E320 routers, you must include the adapter identifier as part of the interface specifier. For example, the following command specifies a Gigabit Ethernet interface on port 0 of the IOA installed in the upper adapter bay of slot 3.
- host1(config)#interface gigabitEthernet 3/0/0
