unicast-suppression { ratio | pps max-pps }

Ethernet interface view, port group view

ratio: Maximal ratio of unicast traffic to the total transmission capability of an 
Ethernet interface, in the range of 1 to 100. The smaller the ratio is, the less 
unicast traffic is allowed through the interface.

pps max-pps: Specifies the maximal number of unknown unicast packets passing 
through an Ethernet interface per second. The max-pps argument ranges from 1 
to 148,810, in pps, representing packets per second.

Use the unicast-suppression command to configure a unicast storm 
suppression ratio.

Use the undo unicast-suppression command to restore the default unicast 
suppression ratio.

By default, all unicast traffic is allowed to go through an Ethernet interface, that is, 
unicast traffic is not suppressed.

If you execute this command in Ethernet interface view, the configuration takes 
effect only on the current interface. If you execute this command in port group 
view, the configuration takes effect on all ports in the port group.

Note that when unicast traffic exceeds the maximum value configured, the system 
will discard the extra packets so that the unknown unicast traffic ratio can drop 
below the limit to ensure that the network functions properly.

n

# Allow unicast traffic equivalent to 20% of the total transmission capability of the 
interface to pass through Ethernet 1/0 and suppress the excessive unknown 
unicast packets.
