Interface Naming Overview

Each interface has an interface name, which specifies the media type, the slot in
which the FPC or DPC is located, the location on the FPC where the PIC is installed,
and the PIC or DPC port. The interface name uniquely identifies an individual network
connector in the system. You use the interface name when configuring interfaces
and when enabling various functions and properties, such as routing protocols, on
individual interfaces. The system uses the interface name when displaying information
about the interface, for example, in the
The interface name is represented by a physical part, a channel part, and a logical
part in the following format:
The channel part of the name is optional for all interfaces except channelized DS3,
E1, OC12, and STM1 interfaces.
The following sections provide interface naming configuration guidelines:
