Interface naming conventions

A port is named in the chassis-id/slot-number/port-index format.

• chassis-id—IRF member ID of the device. This argument defaults to 1. The IRF member ID always takes effect, whether or not the device has formed an IRF fabric with other devices. If the device is alone, the device is regarded a one-chassis IRF fabric.

• slot-number—Slot number of the front panel or expansion interface card.

  • The slot number of the front panel is fixed at 0 for all 5940 switches.

  • The slot numbers of expansion interface cards vary by device model. To identify the number of a slot, examine its slot number mark on the chassis.

• port-index—Index of the port on the device. Port index depends on the number of ports available on the device. To identify the index of a port, examine its port index mark on the chassis.

For example:

• On the single-chassis IRF fabric Sysname, Ten-GigabitEthernet 1/0/1 represents the first fixed port on the device. Set its link type to trunk, as follows:

  <Sysname> system-view
  [Sysname] interface ten-gigabitethernet 1/0/1
  [Sysname-Ten-GigabitEthernet1/0/1] port link-type trunk
  

• On the multi-chassis IRF fabric Master, Ten-GigabitEthernet 3/0/1 represents the first fixed port on member device 3. Set its link type to trunk, as follows:

  <Master> system-view
  [Master] interface ten-gigabitethernet 3/0/1
  [Master-Ten-GigabitEthernet3/0/1] port link-type trunk
