Identifying switch ports and interfaces

Physical ports on the switch and their corresponding logical software interfaces are identified using the format:

member/slot/port

On the 6200 Switch Series

  • member: Member number of the switch in a Virtual Switching Framework (VSF) stack. Range: 1 to 8. The primary switch is always member 1. If the switch is not a member of a VSF stack, then member is 1.
  • slot: Always 1. This is not a modular switch, so there are no slots.
  • port: Physical number of a port on the switch.

For example, the logical interface 1/1/4 in software is associated with physical port 4 in slot 1 on member 1.

On the 6300 Switch Series

  • member: Member number of the switch in a Virtual Switching Framework (VSF) stack. Range: 1 to 10. The primary switch is always member 1. If the switch is not a member of a VSF stack, then member is 1.
  • slot: Always 1. This is not a modular switch, so there are no slots.
  • port: Physical number of a port on the switch.

For example, the logical interface 1/1/4 in software is associated with physical port 4 on member 1.

On the 6400 Switch Series

  • member: Always 1. VSF is not supported on this switch.
  • slot: Specifies physical location of a module in the switch chassis.
    • Management modules are on the front of the switch in slots 1/1 and 1/2.
    • Line modules are on the front of the switch starting in slot 1/3.
  • port: Physical number of a port on a line module.

For example, the logical interface 1/3/4 in software is associated with physical port 4 in slot 3 on member 1.

On the 83xx Switch Series

  • member: Always 1. VSF is not supported on this switch.
  • slot: Always 1. This is not a modular switch, so there are no slots.
  • port: Physical number of a port on the switch.

For example, the logical interface 1/1/4 in software is associated with physical port 4 on the switch.

If using breakout cables, the port designation changes to x:y, where x is the physical port and y is the lane when split to 4 x 10G or 4 x 25G. For example, the logical interface 1/1/4:2 in software is associated with lane 2 on physical port 4 in slot 1 on member 1.

On the 8400 Switch Series

  • member: Always 1. VSF is not supported on this switch.
  • slot: Specifies physical location of a module in the switch chassis.
    • Management modules are on the front of the switch in slots 1/5 and 1/6.
    • Line modules are on the front of the switch in slots 1/1 through 1/4, and 1/7 through 1/10.
  • port: Physical number of a port on a line module

For example, the logical interface 1/1/4 in software is associated with physical port 4 in slot 1 on member 1.
