Unicast-Suppression - HP 3600 v2 Series Command Reference Manual

unicast-suppression

Syntax
unicast-suppression { ratio | pps max-pps | kbps max-kbps }
undo unicast-suppression
View
Layer 2 Ethernet interface view, port group view
Default level
2: System level
Parameters
ratio: Sets the unknown unicast suppression threshold as a percentage of the maximum interface rate,
ranging from 1 to 100. The smaller the percentage, the less unknown unicast traffic is allowed to pass
through.
pps max-pps: Specifies the maximum number of unknown unicast packets that the Ethernet interface can
forward per second.
For FE ports, the max-pps argument ranges from 1 to 1,488,100 pps.
•
• For GE ports, the max-pps argument ranges from 1 to 14,881,000 pps.
kbps max-kbps: Specifies the maximum number of kilobits of unknown unicast traffic that the Ethernet
interface can forward per second.
• For FE ports, the max-kbps argument ranges from 1 to 1,000,000 kbps.
For GE ports, the max-kbps argument ranges from 1 to 10,000,000 kbps.

Description
Use unicast-suppression to set the unknown unicast suppression threshold on one or multiple Ethernet
interfaces.
Use undo unicast-suppression to restore the default.
By default, Ethernet interfaces do not suppress unknown unicast traffic.
If you execute this command in Ethernet interface view, the configuration will take effect only on the
interface. If you execute this command in port group view, the configuration will take effect on all ports
in the port group.
When you configure the unknown unicast suppression threshold in kbps, if the input value is less than 64,
the value that takes effect is 64; if the input value is greater than 64 but is not a multiple of 64, the value
that takes effect is a multiple of 64 greater than and nearest to the input value.
When unknown unicast traffic exceeds the threshold you configure, the system discards unknown unicast
packets until the unknown unicast traffic drops below the threshold.
NOTE:
If you set different unknown unicast 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.
