Command Usage
This command is only active in the spanning tree root device. This com-
mand sets the maximum time (in seconds) a device can wait without receiv-
ing 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.
