5.2.1.7 set spantree maxage
Use this command to set the bridge maximum aging time. This is the maximum time (in seconds)
a device can wait without receiving a configuration message (bridge “hello”) 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.
