A Forwarding Database forwards or filter
packets on behalf of the managing controller, service platform or access point. The
bridge reads the packet's destination MAC address and decides to either forward the
packet or drop (filter) it. If it's 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:
Procedure
Go to Configuration →
Devices.
The Device Configuration
screen displays. This screen lists wireless controllers, service
platforms and access points within the managed network.
Select a device from the list
displayed.
The selected device's
configuration screen displays.
Expand Profile Overrides
→ Network and select Forwarding
Database.
The Forwarding Database
configuration screen displays.

Define a Bridge Aging Time
from 0, 10-1,000,000 seconds.
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.
Use the +Add Row button
to create a new row within the Static Forwarding
Table.
Set or override a destination
MAC
Address.
The bridge reads the packet's
destination MAC address and decides to forward the packet or drop (filter) it.
If it's determined the destination MAC is on a different network, it forwards
the packet to the segment. If the destination MAC is on the same network
segment, the packet is dropped (filtered).
Define the target VLAN ID if the
destination MAC is on a different network segment.
Provide an Interface Name
used as the target destination interface for the target MAC address.
Click OK to save the
changes.
Click Reset to revert
to the last saved configuration.
