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 uninterested 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. Typically, 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.
Broadcast/
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.
Broadcast/
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.
