Profile Overrides - Forwarding Database

About this task

A Forwarding Database forwards or filters 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 override an access point profile's forwarding database configuration:

Procedure

Go to Configuration → Devices → Device Overrides.

The Device Overrides screen displays. This screen lists devices within the managed network.
Select an access point.

The selected access point's configuration menu 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.

In the Static Forwarding Table table, click +Add Row and define the following:


MAC Address	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).
VLAN ID	Define the target VLAN ID if the destination MAC is on a different network segment.
Interface Name	Provide the name of the interface used as the target destination interface for the target MAC address.
