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.
