Spanning-Tree Commands

clear spanning-tree detected-protocols

The clear spanning-tree detected-protocols Privileged EXEC mode command restarts the protocol migration process (forces renegotiation with neighboring devices) on all interfaces or on a specified interface.

Syntax

clear spanning-tree detected-protocols [ethernet interface port-channel port- channel-number]

Parameters

•interface — A valid Ethernet port.

•port-channel-number— A valid port-channel number.

Default Configuration

This command has no default configuration.

Command Modes

Privileged EXEC mode

User Guidelines

This feature should be used only when working in RSTP or MSTP mode.

Example

The following example restarts the protocol migration process on Ethernet port 11.

Console# clear spanning-tree detected-protocols ethernet ext.11

spanning-tree mst priority

The spanning-tree mst priority Global Configuration mode command configures the device priority for the specified spanning-tree instance. To restore the default configuration, use the no form of this command.

Syntax
