Description

Usage Guidelines

There are no default configurations for this command.

EXEC mode

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

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:
