Naming Convention for Interfaces (e.g. Cisco, Juniper)

Each interface has an interface name, which specifies the media type, the slot in which the interface is located and the 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.

eg Cisco: mediatype stack / slot / port like "ge-0/0/0" or " FastEthernet 0/0"

eg Juniper: mediatype stack / slot / port like "ge-0/0/0"

The convention is as follows (examples):

• mediatype 

  • xe - 10-Gigabit Ethernet interface

  • et - 25/40/100 Gigabit Ethernet interface

  • em - management interface

  • fc - Fiber Channel interface

  • ge - Gigabit Ethernet interface

  • sxe - 10 gigabit service interface

  • xle - 40-Gigabit Ethernet interface

  • fte - 40-Gigabit data plane uplink interface

  • me - management interface

  • em - management interface

• stack or module

  • On standalone switches, the stack number (or Flexible PIC Concentrator) is always 0 .

• slot / module / submodule

  • The number indicates the slot number of the line card that contains the physical interface.

• port

  • Interfaces use the following convention for port numbers: eg 1-48, sfp + 49 through 54
