This command sets the maximum time (in seconds) a device can wait
without receiving a configuration message before attempting to
reconverge. 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.
