To update Radio settings:
1. Navigate to the 802.11 Advanced Settings tab page.
2. Configure the radio settings as required.
3. Click the Update button to apply the changes.
Note: If you are using the two-radio version of the 9160 G2 Wireless Gateway, keep in mind
that both Radio One and Radio Two are configured on this tab. The displayed settings
apply to either Radio One or Radio Two, depending on which radio you choose in the
Radio field (first field on tab). When you have configured settings for one of the
radios, click Update and then select and configure the other radio. Be sure to click
Update to apply the second set of configuration settings for the other radio.
Description
Enabling multicast and broadcast rate limiting can improve overall network performance by limiting the number
of packets transmitted across the network.
Some protocols use multicast and broadcast packets for traffic that the majority of nodes on a network are unin-
terested in. For example, ARP requests for other machines, DHCP or BOOTP messages. For some protocols,
if you set a rate limit control you limit the number of redundant packets transmitted across the network. Typi-
cally, any filtered traffic will be retransmitted at a later time and will not cause difficulties.
• To enable Multicast and Broadcast Rate Limiting, click Enabled.
• To disable Multicast and Broadcast Rate Limiting, click Disabled.
By default the Multicast/Broadcast Rate Limiting option is disabled. Until you enable Multicast/Broadcast Rate
Limiting, the following fields will be disabled.
Enter the rate limit you want to set for multicast and broadcast traffic. The limit should be greater than 1, but less
than 50 packets per second. Any traffic that falls below this rate limit will always conform and be transmitted to
the appropriate destination.
The default and maximum rate limit setting is 50 packets per second.
Setting a rate limit burst determines how much traffic bursts can be before all traffic exceeds the rate limit. This
burst limit allows intermittent bursts of traffic on a network above the set rate limit.
The default and maximum rate limit burst setting is 75 packets per second.
