Enabling Flow Control On A Port; Duplicating The Configuration Of A Port To Other Ports - 3Com 4500 Configuration Manual

To do...
Limit 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.
Follow these steps to enable flow control on a port:
To do...
Enter system view
Enter Ethernet port view
Enable flow control on the
Ethernet port

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, LACP configuration, QoS configuration, STP configuration and initial port
configuration. Refer to the command manual for the configurations that can be duplicated.
Follow these steps to duplicate the configuration of a port to specific ports:
To do...
Enter system view

configuration of a port to
specific ports
