Ethernet Interface Platform Considerations

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

This section describes the line modules and I/O modules that support Ethernet interfaces.

For detailed information about the modules that support Fast Ethernet and Gigabit Ethernet interfaces on the ERX14xx models, ERX7xx models, and the ERX310 router:

For detailed information about the modules that support Gigabit Ethernet and 10-Gigabit Ethernet interfaces on the E120 and E320 Broadband Services routers:

Numbering Scheme

When configuring or managing an interface, you must know the numbering scheme for identifying an interface. The numbering scheme depends on the type of E Series router that you have.

ERX7xx Models, ERX14xx Models, and the ERX310 Router

Use the slot/port [.subinterface] format to identify Ethernet interfaces and subinterfaces.

For information about installing line modules and I/O modules in ERX routers, see the Installing Modules chapter in the ERX Hardware Guide.

E120 and E320 Routers

Use the slot/adapter/port [.subinterface] format to identify Ethernet interfaces and subinterfaces.

For information about installing line modules and IOAs in the E120 and E320 routers, see the Installing Modules chapter in the E120 and E320 Hardware Guide.

Interface Specifier

The configuration task examples in this chapter use the format for ERX7xx models, ERX14xx models, and the ERX310 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

For more information about interface types and specifiers on E Series models, see Interface Types and Specifiers in JunosE Command Reference Guide.
