5. Type a short description for Bridge 2 in the Description text box.
6. Aging time is the number of seconds a MAC-address will be held in the forwarding database after receiving
a packet from this MAC address. The entries in the forwarding database are periodically timed out to
ensure they won't stay around forever. If desired, type a value (in seconds) for the forwarding table aging
time in the Aging Time box. The default value for this setting 300 seconds (5 minutes).
7. The Model 6081RC periodically checks the forwarding database for timed-out entries which are then
deleted. The Garbage Collection Interval is the time (in seconds) that between each checks of the forward-
ing database.
8. Spanning tree is a link management protocol that provides path redundancy while preventing undesirable
loops in the network. For a Layer 2 Ethernet or Token Ring network to function properly, only one active
path must exist between two stations. Spanning-tree operation is transparent to end stations, which cannot
detect whether they are connected to a single LAN segment or a switched LAN of multiple segments.
