Limiting Broadcast, Multicast, or Unknown-Unicast Rates
HP devices forward all traffic at wire speed. However, some third-party networking devices cannot handle high
forwarding rates for these types of packets. You can limit the number of broadcast, multicast, or unknown-unicast
packets an HP device forwards each second using the following methods.
The limits are individually configurable for broadcasts, multicasts, and unknown-unicasts.
NOTE: By default, IP Multicast (including IGMP) is disabled. You can enable it using the ip multicast passive |
active command. As long as IP Multicast is enabled (regardless of whether it is passive or active), no IP Multicast
packets (not even IGMP packets) are limited. See "Configuring IP Multicast Traffic Reduction" on page 12-1.
Limiting Broadcasts
To limit the number of broadcast packets an HP device can forward each second, use the following CLI method.
USING THE CLI
To globally limit the number of broadcast packets an HP 9304M, HP 9308M, or HP 9315M Routing Switch
forwards to 100,000 per second, enter the following command at the global CONFIG level of the CLI:
HP9300(config)# broadcast limit 100000
HP9300(config)# write memory
To limit the number of broadcast packets sent on port 1/3 to 80,000, enter the following commands:
HP9300(config)# int ethernet 1/3
HP9300(config-if-1/3)# broadcast limit 80000
HP9300(config-if-1/3)# write memory
USING THE WEB MANAGEMENT INTERFACE
You cannot perform this procedure using the Web management interface.
Limiting Multicasts
To limit the number of multicast packets an HP device can forward each second, use the following CLI method.
USING THE CLI
To globally limit the number of multicast packets an HP 9304M, HP 9308M, or HP 9315M Routing Switch forwards
to 120,000 per second, enter the following command at the global CONFIG level of the CLI:
HP9300(config)# multicast limit 120000
HP9300(config)# write memory
To limit the number of multicast packets sent on port 3/6 to 55,000, enter the following commands:
HP9300(config)# int ethernet 3/6
HP9300(config-if-3/6)# multicast limit 55000
HP9300(config-if-3/6)# write memory
USING THE WEB MANAGEMENT INTERFACE
You cannot perform this procedure using the Web management interface.
Limiting Unknown Unicasts
To limit the number unknown unicast packets an HP device can forward each second, use the following CLI
method.
