Parameter
ratio
: Maximum ratio of received unknown unicast traffic to the total bandwidth on the
Ethernet port. The value ranges from 1 to 100 (in step of 1) and defaults to 100. The
smaller the ratio is, 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). The value ranges from 1 to 148,810.
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.
