Multicast-Suppression - H3C S3100 Series Command Manual

An RJ-45 interface can operate in MDI or MDI-X mode.
To connect two RJ-45 interfaces operating in the same MDI mode, use a crossover cable; to
connect two RJ-45 interfaces operating in different MDI modes, use a straight-through cable.
Description
Use the mdi command to set the MDI mode for a port.
Use the undo mdi command to restore the default setting.
By default, a port operates in auto-sensing MDI mode.
Example
# Set the MDI mode of Ethernet 1/0/1 to MDI.

multicast-suppression

Syntax
multicast-suppression bps max-bps
undo multicast-suppression
View
Ethernet port view
Parameter
max-bps: Maximum number of kilobits of unknown multicast and unicast bits that can be received per
second on an Ethernet port (in step of 64).
For a 100-Mbps Ethernet port, the max-bps argument is in the range 64 to 99,968.
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.
