Displayed items:

zInterface: Interface information

17 GigabitEthernet 0/1: Port number interface name

-Port number: Port number (1 to 33).

-Interface name: Interface name displayed following selection from GigabitEthernet 0/1-8, IO_Unit 0 0-7 1, TenGigabitEthernet 1/1-2, port-channel 1-7, and none.

If no port-channel port has been created or no TenGigabitEthernet is mounted, "none" is displayed for the interface name.

zPort status: Port status

-listening: Listening status Receiving BPDU frames

-learning: Learning status Preparing to transfer data traffic

-forwarding: Forwarding status Ready to transfer data traffic

-blocking: Blocking status Data traffic blocked

zPort path cost: Port path cost value

The port path cost value ranges from 0 to 65535.

xx(auto) indicates the path cost value, which is calculated automatically and depends on the link speed.

auto: The calculated master-port link speed minus 1 is set for the 10Mbps-100, 100Mbps-19, 1Gbpd-4, 10Gbpd-2, and port-channel ports.

zPort priority: Port priority

The port priority ranges from 0 to 255.
