Interface Naming

Each interface has an interface name, which specifies the media type, the slot the FPC is located in, the location on the FPC that the PIC is installed in, and the PIC 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 show interfaces command.

The interface name is represented by a physical part, a channel part, and a logical part in the following format:

physical<:channel>.logical 

The channel part of the name is optional for all interfaces except Channelized T3, E1, OC-12, and STM-1 interfaces.

The following sections provide interface naming configuration guidelines:

• Physical Part of an Interface Name
• Logical Part of an Interface Name
• Separators in an Interface Name
• Channel Part of an Interface Name
