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
Console(config)#
