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.
Follow these steps to enable flow control on a port:
To do... Use the command... Remarks
Enter system view

By default, flow control is not
enabled on the 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, protocol-based VLAN configuration, LACP configuration, QoS configuration,
GARP 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:

copy configuration source { interface-type
interface-number | aggregation-group
source-agg-id } destination { interface-list
[ aggregation-group destination-agg-id ] |
aggregation-group destination-agg-id }
Required
z If you specify a source aggregation group ID, the system will use the port with the smallest port
number in the aggregation group as the source.
z If you specify a destination aggregation group ID, the configuration of the source port will be copied
to all ports in the aggregation group and all ports in the group will have the same configuration as
that of the source port.
