Configuring a Broadcast Limit on the Switch

3400cl/6400cl Switches: Broadcast-Limit on these switches is config­
■
ured as a percentage on a per-port basis.
■ 5300xl Switches: Broadcast-Limit on these switches is configured glo­
bally (on all ports) as a fixed limit.
Broadcast-Limit on the 3400cl/6400cl Switches.
Syntax: interface < port-list > broadcast-limit < 0 - 99 > (3400cl/6400cl Switches)
Configures the theoretical maximum bandwidth percentage
that the specified switch ports use to limit broadcasts and
multicasts. The switch drops any broadcast or multicast
traffic exceeding that limit. Zero (0) disables the feature.
Note: This feature is not appropriate for networks requiring
high levels of IPX or RIP broadcast traffic.
For example, to configure a broadcast limit of 70% on ports 1-12:
HPswitch(config)# interface 1-12 broadcast-limit 70
To later disable broadcast limiting on ports 11 and 12:
HPswitch(config)# interface 11-12 broadcast-limit 0
Broadcast-Limit on the 5300xl Switches.
Syntax: [no] broadcast-limit
Enables or disables broadcast limiting for outbound
broadcasts on all ports on the switch. When enabled, this
command limits outbound broadcast packets to 1,000 per
second on each port, regardless of packet size.
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 broad cast
limit to the setting currently in the startup-config file.
