Ethernet interface may not be the one that actually takes effect. To display the actual multicast
suppression threshold value on an Ethernet interface, you can use the
display interface
command.
•
When the
pps
keyword is not specified, or the suppression granularity is set to 1, the value of the
pps
keyword must be no smaller than 1, and the multicast suppression threshold value is the one that
actually takes effect on the Ethernet interface.
Description
Use
multicast-suppression
to set the multicast suppression threshold on an Ethernet interface.
Use
undo multicast-suppression
to restore the default.
By default, Ethernet interfaces do not suppress multicast traffic.
When multicast traffic exceeds the threshold you configure, the system discards multicast packets until the
multicast traffic drops below the threshold.
Examples
# Set the multicast threshold to 20% on GigabitEthernet 1/0/1.

Parameters
ratio
: Sets the unknown unicast suppression threshold as a percentage of the transmission capability of
the 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. The
max-pps
argument ranges from 1 to 1,488,100 pps.
•
When the
pps
keyword is specified, and a suppression granularity larger than 1 is specified on the
device, the value of the
pps
keyword must be no smaller than and an integral multiple of the
granularity. The unknown unicast suppression threshold value configured through this keyword on
an Ethernet interface may not be the one that actually takes effect. To display the actual unknown
unicast suppression threshold value on an Ethernet interface, you can use the
display interface
command.

When the
pps
keyword is not specified, or the suppression granularity is set to 1, the value of the
pps
keyword must be no smaller than 1, and the unknown unicast suppression threshold value is the
one that actually takes effect on the Ethernet interface.
