Unicast-Suppression - HP A5830 Series Command Reference Manual

[Sysname-GigabitEthernet1/0/1] speed auto 10 1000

unicast-suppression

Description
Use the unicast-suppression command to set the unknown unicast suppression threshold on one or
multiple Ethernet interfaces.
Use the undo unicast-suppression command to restore the default.
By default, Ethernet interfaces do not suppress unknown unicast traffic.
If you execute this command in Ethernet interface view, the configurations take effect only on the interface.
If you execute this command in port group view, the configurations take effect on all ports in the port
group.
When unknown unicast traffic exceeds the threshold you configure, the system discards unknown unicast
packets until the unknown unicast traffic drops below the threshold.
If you set different unknown unicast suppression thresholds in Ethernet interface view or port group view
multiple times, the one configured last takes effect.
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 transmission capability of an
Ethernet interface, 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 GE ports, the max-pps parameter ranges from 1 to 1,488,100 pps.
For 10-GE ports, the max-pps parameter 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 GE ports, the max-kbps parameter ranges from 1 to 1,000,000 kbps.
For 10-GE ports, the max-kbps parameter ranges from 1 to 10,000,000 kbps.
Examples
# Set the unknown unicast threshold to 20% on GigabitEthernet 1/0/1.
