Ethernet interface configuration
commands

broadcast-suppression

Syntax
broadcast-suppression { ratio | kbps max-kbps }
undo broadcast-suppression
View
Ethernet interface view, port group view
Default level
2: System level
Parameters
ratio: Sets the broadcast suppression threshold as a percentage of the maximum interface rate,
ranging from 1 to 100. The smaller the percentage, the less broadcast traffic is allowed to pass
through.
kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet
interface can forward per second.
•
For 100-Mbps ports, the max-kbps argument ranges from 1 to 100,000 kbps.
•
For 1000-Mbps ports, the max-kbps argument ranges from 1 to 1,000,000 kbps.
Description
Use broadcast-suppression to set the broadcast suppression threshold on one or multiple
Ethernet interfaces.
Use undo broadcast-suppression to restore the default.
By default, Ethernet interfaces do not suppress broadcast traffic.
If you execute this command in Ethernet interface view, the configuration takes effect only on the
interface. If you execute this command in port group view, the configuration takes effect on all ports
in the port group.
When you configure the suppression threshold in kbps, the actual suppression threshold might be
different from the configured one as follows:
•
If the configured value is smaller than 64, the value of 64 takes effect.
•
If the configured value is greater than 64 but not a multiple of 64, the multiple of 64 that is
greater than and closest to the configured value takes effect.
When broadcast traffic exceeds the broadcast suppression threshold, the system discards
broadcast packets until the broadcast traffic drops below the threshold.
NOTE:
• If you set different broadcast suppression thresholds in Ethernet interface view or port group
view multiple times, the one configured last takes effect.
• For a particular type of traffic, configure either storm suppression or storm control, but not both. If
both of them are configured, you may fail to achieve the expected storm control effect.
