Enabling Flow Control On A Port; Duplicating The Configuration Of A Port To Other Ports - 3Com 4210 9-Port Configuration Manual

Operation
Limit unknown multicast and
unknown unicast traffic
received on the current port

Enabling Flow Control on a Port

Flow control is enabled on both the local and peer switches. If congestion occurs on the local switch:
The local switch sends a message to notify the peer switch of stopping sending packets to itself or
reducing the sending rate temporarily.
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.

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.
