5.3.5.9 Forwarding Database
Profile Network Configuration
A Forwarding Database is used by a bridge to forward or filter packets. The bridge reads the packet's destination MAC
address and decides to either forward the packet or drop (filter) it. If it is determined the destination MAC is on a
different network segment, it forwards the packet to the segment. If the destination MAC is on the same network
segment, the packet is dropped (filtered). As nodes transmit packets through the bridge, the bridge updates its
forwarding database with known MAC addresses and their locations on the network. This information is then used
to decide to filter or forward the packet.

The aging time defines the length of time an entry will remain in the bridge's forwarding table before being
deleted due to lack of activity. If an entry replenishments a destination, generating continuous traffic, this timeout
value will never be invoked. However, if the destination becomes idle, the timeout value represents the length of
time that must be exceeded before an entry is deleted from the forwarding table. The default setting is 300
seconds.
