5.2.6.10 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.
To define a forwarding database configuration:
1. Select the Configuration
2. Select Devices.
3. Select System Profile
4. Expand the Network
5. Define a Bridge Aging Time
The aging time defines the length of time an entry will remain in the bridge's forwarding table before it is 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.
