For a GigabitEthernet port, the
max-bps
argument is in the range 64 to 1,000,000.
Description
Use the
multicast-suppression
command to limit unknown multicast and unknown
unicast traffic allowed to be received on the current port.
Use the
undo
multicast-suppression
command to restore the default unknown
multicast and unknown unicast traffic suppression setting on the current port.
After the configuration, the switch will suppress the unknown multicast and unknown
unicast traffic simultaneously.
When the sum of incoming unknown multicast traffic and unknown unicast traffic on the
port exceeds the traffic threshold you set, the system drops the packets exceeding the
threshold to reduce the unknown multicast and unknown unicast traffic ratio to the
reasonable range, so as to keep normal network service..
By default, the switch does not suppress unknown multicast and unknown unicast
traffic.
Note:
With line rate (LR) applied on one port in the inbound direction or the Traffic Policing
enabled, multicast suppression cannot be enabled on any port of the device, and vice
versa. Refer to the QoS part for information about LR and Traffic Policing.
Example
# Set the maximum number of unknown multicast and unknown unicast traffic that can
be received per second by Ethernet 1/0/2 to 128Kbps.
