Reference port: Select a port as the reference port from the ports that are in up state and with the

same class-two configurations as the corresponding aggregate interface. The selection is
performed in the following order: full duplex/high speed, full duplex/low speed, half duplex/high

speed, and half duplex/low speed, with full duplex/high speed being the most preferred. If two

ports with the same duplex mode/speed pair are present, the one with the lower port number wins.

Port attribute configuration includes the configuration of the port rate, duplex mode, and link state.

For more information about class-two configurations, see H3C WX3000E Series Wireless Switches
Switching Engine
Configuration Guide.

To guarantee a successful static aggregation, make sure that the ports at the two ends of each link
to be aggregated are consistent in Selected/Unselected state. To guarantee a successful dynamic
aggregation, make sure that the peer ports of the ports aggregated at one end are also aggregated.

The two ends can automatically negotiate the Selected state of the ports.

These types of ports cannot be assigned to Layer 2 aggregate groups: MAC address
authentication-enabled ports, port security-enabled ports, packet filtering-enabled ports, Ethernet

frame filtering-enabled ports, IP source guard-enabled ports, and 802.1X-enabled ports.

H3C does not recommend you to assign the reflector port of a port mirroring group to an
aggregation group. For more information about reflector ports, see the chapter "

Port mirroring

configuration

."

Removing a Layer 2 aggregate interface also removes the corresponding aggregation group.
Meanwhile, the member ports of the aggregation group, if any, leave the aggregation group.

When a load-sharing aggregation group becomes a non-load-sharing aggregation group because
of insufficient load sharing resources, one of the following problems may have occurred: The

number of Selected ports of the actor is inconsistent with that of the partner, which may result in

incorrect traffic forwarding; the peer port of a Selected port is an Unselected port, which may result
anomalies in upper-layer protocol and traffic forwarding. You should fully consider the situation

when making configuration.
