Enter the number of seconds (between 4 and 30) that the bridge will wait for the primary port to pass a frame before switching the secondary port into the forwarding state, so that the secondary port can route data when the primary port fails to do so.
Max. Age Time (6–40)
The bridge maintains a routing database, containing unique source addresses of frames that the bridge receives from each network to which it is connected. The database relates a station’s source address to a port on the bridge, and the bridge uses the database to choose which port it will use to transmit frames with a destination address matching the entry in the database.
The bridge compares each new frame’s source address to entries within its internal routing database. If the bridge does not find a new frame’s source address in the routing database, it adds the new frame’s source address to the database.
The Max. Age Time field sets the amount of time in seconds that the bridge stores any source address. When the bridge stores a frame’s source address, the address remains in the routing database for the length of time specified in Max. Age Time. If the bridge receives a new frame, and finds the frame’s source address in the database, the bridge automatically resets the Max. Age Time, restarting the count. If the aging timer for an entry in the database expires before the bridge receives another frame with the same source address, the bridge removes the source address from its internal routing database. This prevents the database from storing information about inactive network stations.
