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 hello-time 5
Console(config)#
Console(config)#spanning-tree max-age 40
Console(config)#
