Command Usage

This command sets the maximum time (in seconds) a device can wait without receiving a configuration message before attempting to reconfigure. All device ports (except for designated ports) should receive configuration messages at regular intervals. Any port that ages out STP information (provided in the last configuration message) becomes the designated port for the attached LAN. If it is a root port, a new root port is selected from among the device ports attached to the network.

Example

Console(config)#spanning-tree max-age 40

Console(config)#

spanning-tree priority

Use this command to configure the Spanning Tree priority globally for this switch. Use the no form to restore the default.
