Limit unknown multicast and 
unknown unicast traffic 
received on the current port 
multicast-suppression bps 
max-bps 
Optional 
The switch will suppress the 
unknown multicast and 
unknown unicast traffic 
simultaneously after the 
configuration. 
By default, the switch does not 
suppress unknown multicast 
and unknown unicast traffic. 
 
Enabling Flow Control on a Port 
Flow control is enabled on both the local and peer switches. If congestion occurs on the local switch: 
z  The local switch sends a message to notify the peer switch of stopping sending packets to itself or 
reducing the sending rate temporarily. 
z  The peer switch will stop sending packets to the local switch or reduce the sending rate temporarily 
when it receives the message; and vice versa. By this way, packet loss is avoided and the network 
service operates normally.

Duplicating the Configuration of a Port to Other Ports 
To make other ports have the same configuration as that of a specific port, you can duplicate the 
configuration of a port to specific ports.  
Specifically, the following types of port configuration can be duplicated from one port to other ports: 
VLAN configuration, protocol-based VLAN configuration, LACP configuration, QoS configuration, 
GARP configuration, STP configuration and initial port configuration. For the detailed copy content, 
please refer to the Command Manual.
