Prevent Messages Destined for a Specific Multicast Group from Being Forwarded to the Wireless LAN
If devices on your Ethernet network use multicast packets to communicate and these packets are not required by your
wireless clients, you can set up a Static MAC filter to preserve wireless bandwidth. For example, if routers on your
network use a specific multicast address (such as 01:00:5E:00:32:4B) to exchange information, you can set up a filter to
prevent these multicast packets from being forwarded to the wireless network:
Wired MAC Address: 01:00:5E:00:32:4B
Wired Mask: FF:FF:FF:FF:FF:FF
Wireless MAC Address: 00:00:00:00:00:00
Wireless Mask: 00:00:00:00:00:00
Result: The unit does not forward any packets that have a destination address of 01:00:5E:00:32:4B to the wireless
network.
Configure Storm Threshold Filtering
Click Configure > Filtering > Storm Threshold to use threshold limits to prevent broadcast/multicast overload.
Storm Threshold is an advanced Bridge setup option that you can use to protect the network against data overload by
specifying:
A maximum number of frames per second as received from a single network device (identified by its MAC address).
An absolute maximum number of messages per port.
The Storm Threshold parameters let you specify a set of thresholds for each port of the unit, identifying separate values
for the number of broadcast messages per second and multicast messages per second.
When the number of frames for a port or identified station exceeds the maximum value per second, the unit ignores all
subsequent messages issued by the particular network device, or ignores all messages of that type.
The following parameters are configurable:
Per Address Threshold: Enter the maximum allowed number of packets per second.
Ethernet Threshold: Enter the maximum allowed number of packets per second.
Wireless Threshold: Enter the maximum allowed number of packets per second.
Configure Broadcast Protocol Filtering
Click Configure > Filtering > Broadcast Protocol to deny specific IP broadcast, IPX broadcast, and multicast traffic.
