Enable Broad-
cast/Multicast
Rate Limiting
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.
Broad-
cast/Multicast
Rate Limit
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.
Broad-
cast/Multicast
Rate Limit
Burst
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.
