Port - H3C s3100 series Command Manual

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.
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.

Parameter
interface-list: Ethernet interface list, in the format of interface-type interface-number [ to interface-type
interface-number ] &<1-10>, where &<1-10> indicates that you can specify up to 10 port ranges.
Description
Use the port command to add Ethernet interface(s) to a specified port group.
Use the undo group-member command to remove specified Ethernet interface(s) from a port group.
By default, a port group is empty, that is, there is no Ethernet interface in it.
