Prevent Messages Destined for a Specific Multicast Group from Being Forwarded to the Wireless LAN
If there are devices on your Ethernet network that 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 the Configure button, the Filtering tab, and the Storm Threshold sub-tab 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.
