Network Port Interface Names on an EX8200 Virtual Chassis

Network interfaces in Junos OS are specified as follows:

type-fpc / pic / port

This topic discusses network-port naming conventions for the network-facing interfaces on EX8200 member switches in an EX8200 Virtual Chassis. For information on interface naming conventions for Virtual Chassis Ports (VCPs) in an EX8200 Virtual Chassis, see Virtual Chassis Port (VCP) Interface Names in an EX8200 Virtual Chassis.

An EX8200 Virtual Chassis network interface name uses these conventions:

  • type—EX8200 member switch interfaces use the following media types:

    • ge—Gigabit Ethernet interface

    • xe—10–Gigabit Ethernet interface

  • fpc—Flexible PIC Concentrator. In an EX8200 Virtual Chassis, the FPC number indicates the slot number of the line card within the Virtual Chassis. The FPC number on member 0 is always 0 through 15. The FPC number on member 1 is always 16 through 31.

    The EX8200 Virtual Chassis reserves 16 FPC slot numbers for each member switch, regardless of whether the member switch is an EX8208 or an EX8216 switch. For EX8208 switches, therefore, FPC numbers 8 through 15 and 24 through 31 are not used.

  • pic— PIC (Physical Interface Card) number in interface names. On EX8200 member switches in an EX8200 Virtual Chassis, the PIC number is always 0.

  • port—Port number. On EX8200 switches, the network ports are numbered from left to right on each line card. On line cards that have two rows of ports, the ports on the top row start with 0 followed by the remaining even-numbered ports, and the ports on the bottom row start with 1 followed by the remaining odd-numbered ports.
