Global Configuration

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 STA 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
