OMMANDS FOR THERNET
unicast-suppression { ratio | pps max-pps }
undo unicast-suppression
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
suppression ratio.
Use the
undo unicast-suppression
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
Currently, these two commands are not supported.
# 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.
