Parameters
ratio : Maximum ratio of the unknown unicast traffic allowed on the port to the total transmission capacity
of the port. This argument ranges from 1 to 100 (in step of 1) and defaults to 100. The smaller the ratio,
the lesser unknown unicast traffic is allowed to be received.
max-pps : Maximum number of unknown unicast packets allowed to be received per second on the
Ethernet port (in pps). This argument ranges from 1 to 148,810 (for Ethernet ports) or 1 to 262,143 (for
GigabitEthernet ports).
Description
Use the unicast-suppression command to limit the unknown unicast traffic allowed to be received on
the current port.
Use the undo broadcast-suppression command to restore the default unknown unicast suppression
setting on the port.
When incoming unknown unicast traffic exceeds the unknown unicast traffic threshold you set, the
system drops the packets exceeding the threshold to reduce the unknown unicast traffic ratio to the
reasonable range, so as to keep normal network service.
By default, the switch does not suppress unknown unicast traffic.
Examples
# Allow unknown incoming unicast traffic on Ethernet 1/0/1 to occupy at most 20% of the transmission
capacity of the port, and suppress the unknown unicast traffic that exceeds the specified range.
