Physical Part of an Interface Name

The M-series and T-series routing platforms use one convention, while the J-series routing platform uses another.

• M-series and T-series interface names—On the M-series and T-series platforms, when you display information about an interface, you specify the interface type, the slot in which the Flexible PIC Concentrator (FPC) is installed, the slot on the FPC in which the Physical Interface Card (PIC) is located, and the configured port number.

  In the physical part of the interface name, a hyphen (-) separates the media type from the FPC number, and a slash (/) separates the FPC, PIC, and port numbers:

  type-fpc/pic/port

Note: Exceptions to the type-fpc/pic/port physical description include the aggregated Ethernet and aggregated SONET/SDH interfaces, which use the syntax aenumber and asnumber, respectively.

• J-series interface names—On the J-series routing platform, when you display information about an interface, you specify the interface type, the slot in which the Physical Interface Module (PIM) is installed, 0, and the configured port number.

  In the physical part of the interface name, a hyphen (-) separates the media type from the PIM number, and a slash (/) separates the PIM, 0, and port numbers:

  type-pim/0/port

Note: An exception to the type-pim/0/port physical description is the Integrated Services Digital Network (ISDN) dialer interface, which uses the syntax dlnumber.
