HP ProCurve 6120G/XG Configuration Manual page 327

Syntax: broadcast-limit <0-99>
Enables or disables broadcast limiting for outbound
broadcasts on a selected port on the switch. The value selected
is the percentage of traffic allowed, for example, broadcast-limit
5 allows 5% of the maximum amount of traffic for that port. A
value of zero disables broadcast limiting for that port.
Note: You must switch to port context level before issuing the
broadcast-limit command.
Note: This feature is not appropriate for networks requiring
high levels of IPX or RIP broadcast traffic.
Syntax: show config
Displays the startup-config file. The broadcast limit setting
appears here if enabled and saved to the startup-config file.
Syntax: show running-config
Displays the running-config file. The broadcast limit setting
appears here if enabled. If the setting is not also saved to the
startup-config file, rebooting the switch returns broadcast
limit to the setting currently in the startup-config file.
For example, the following command enables broadcast limiting of 1 percent
of the traffic rate on the selected port on the switch:
ProCurve(int B1)# broadcast-limit 1
For a one Gbps port this results in a broadcast traffic rate of ten Mbps.
