multicast-suppression

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