    Interface Types and Specifiers

    Many commands take the variables interfaceType and interfaceSpecifier. Some commands support all types of interfaces, whereas other commands support only certain types of interfaces. Similarly, some commands support all interface specifier formats for a particular interface type, whereas other commands support only certain interface specifier formats.

    Table 1 lists the interface specifiers for each type of interface on ERX7xx models, ERX14xx models, and the Juniper Networks ERX310 Broadband Services Router.

    Note: On ERX7xx models, ERX14xx models, and the ERX310 router, you can use the atm slot/port/vpi/vci interface specifier format as an alternative to the atm slot/port.subinterface format with the specific show interface and show subinterface commands to monitor all ATM 1483 subinterfaces (except NBMA interfaces) as well as the upper-layer interfaces configured over an ATM 1483 subinterface. You cannot, however, use the atm slot/port/vpi/vci format to create or modify an ATM 1483 subinterface.

    Table 2 lists the interface specifiers for each type of interface on the Juniper Networks E120 and E320 Broadband Services Routers.

    Note: On the E120 router and the E320 router you can use the atm slot/adapter/port/vpi/vci interface specifier format as an alternative to the atm slot/adapter/port.subinterface format with the specific show interface and show subinterface commands to monitor all ATM 1483 subinterfaces (except NBMA interfaces) as well as the upper-layer interfaces configured over an ATM 1483 subinterface. You cannot, however, use the atm slot/adapter/port/vpi/vci format to create or modify an ATM 1483 subinterface.
