Command

Modes

EXEC mode

Description

Use this command to display the state of the spanning tree for all named port-channels or 10 Gbps 
Ethernet interfaces. 

Usage

Guidelines

The following describes the port roles, states and types:

•

Port roles—root port, designated port, alternate port and backup port.

•

Port states—discarding, learning, and forwarding.

•

Port types—edge port (PortFast), point-to-point, and shared port.

Examples

To display information on a 10 Gbps Ethernet interface:

switch#show spanning-tree interface tengigabitethernet 0/0
