Limiting Traffic
The R2 has the capability to limit broadcast traffic. The AP 2000 can limit multicast traffic.
R2 Broadcast Rate Limit
The broadcast rate limit filter only applies to incoming traffic on the selected interface.
To limit broadcast traffic, enable or disable broadcast rate limiting at each interface. If
enabling, specify the maximum number of broadcast packets that the interface will forward
every 100 milliseconds (ms). For additional information, refer to Filters on page 2-26.
To access the broadcast rate limit filter using the AP Manager, click on the Filtering button
in the main window to access the Filtering Dialog Box, then click on the Rate Limiting tab.
To access the broadcast rate limit filter using the console port, choose Rate Limiting
Configuration from the main menu.
To access the broadcast rate limit filter using the R2 web interface, select Rate Limiting.
AP 2000 Multicast Rate Limit
The multicast rate limiting filter allows you to restrict the rate at which multicast traffic is
forwarded. By default, multicast traffic is limited to 100 Kb/sec. Disabling this parameter
could cause multicast traffic to use more network bandwidth. Should a broadcast storm
occur when this parameter is disabled, the multicast traffic could cause a serious
degradation of network performance.
When enabling the multicast rate limiting filter, you must specify the maximum number of
multicast packets that the AP 2000 will forward every second.
To access the multicast rate limiting filter using the AP Manager, click on the Filtering
button in the main window to access the Filtering Dialog Box, then click on the Rate
Limiting tab.
To access the multicast rate limiting filter using the console port, choose Module-Specific
Options from the RoamAbout AP Installation Menu. From the module-specific menu,
choose Set Wireless Configuration.
NOTE: Unicast packets with an unknown MAC destination address
are treated as broadcast packets.
