1.1.23 multicast-suppression

Syntax
multicast-suppression { ratio | pps max-pps }
undo multicast-suppression
View
Ethernet port view
Parameter
ratio: Maximum ratio of received multicast 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 less multicast traffic is allowed to be received.
max-pps: Maximum number of multicast packets allowed to be received per second on
the Ethernet port (in pps). The value ranges from 1 to 148,810.
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.
Example
# Allow the incoming multicast traffic on the Ethernet1/0/1 port to occupy at most 20%
of the bandwidth on the port.
