Physical and Layer 2 Interfaces 73
Software Release 2.6.1
C613-02021-00 REV D
Two of the encapsulations supported for synchronous ports (AR410 only)—
Frame Relay and Point-to-Point Protocol—are described in detail in the Point-
to-Point Protocol (PPP) and Frame Relay chapters in the AR400 Series Router
Software Reference.
The Basic Rate and Primary Rate ISDN interfaces (AR410 only) are described in
the Integrated Services Digital Network (ISDN) chapter in the AR400 Series Router
Software Reference.
Naming Interfaces
When you configure an interface, and configure routing over that interface,
you can refer to a physical interface by its simple name or its fully qualified
name.
The simple name for an interface is the interface type, followed by the interface
number. The interface type is an abbreviation of the full name of the interface
(see Table 7 on page 73). The fully qualified name for expansion option ports
includes the expansion bay and the number of the interface within the bay.
When you use commands with a physical interface as a parameter, you have
the option to use either the simple name or the fully qualified name of the
interface.
For examples of valid simple names and the equivalent fully qualified names
see the Interfaces chapter in the AR400 Series Router Software Reference.
To display a summary of all the interfaces on the router, enter the command:
