21.1.3.2 Aggregation of Physical Port
To aggregate multiple physical ports into a logical channel, you can use static aggregation or LACP protocol
for negotiation.
In the case when the static aggregation is used, it is required that the link of the physical port should be up,
and the VLAN attribute of aggregation port and physical port should be identical, and then this port will be
aggregated to the logical channel, regardless of whether the current port accords with the conditions of port
aggregation and whether the port that connects with the physical port accords with the aggregation
conditions.
Prerequisites for ports to be aggregated:
 The link of the port must be up and the port should be negotiated to full-duplex mode.
 The speed of all physical ports should be same during aggregation process, that is, if there is one physical
port that has been aggregated successfully, then the speed of the second physical port must be the same
as the first configured one. Also the vlan attributes of all physical ports must be identical to the aggregated
port.
LACP packets are exchanged between ports in these modes:
 Active—Places a port into an active negotiating state, in which the port initiates negotiations with remote
ports by sending LACP packets.
 Passive—Places a port into a passive negotiating state, in which the port responds to LACP packets it
receives but does not initiate LACP negotiation. In this mode, the port channel group attaches the interface
to the bundle.
If both ports use Passive method, then the aggregation fails. This is because both sides will wait for the other
side to launch aggregation negotiation process.
VALN attributes: PVID, Trunk attribute, vlan-allowed range and vlan-untagged range.
Use the following command to perform aggregation on the physical ports:
Command Description
aggregator-groupagg-idmode { lacp |
static }
Configures aggregation option of the
physical port.
21.1.3.3 Selecting Load Balance Method After Port Aggregation
You can select the load share method to ensure that all ports can share the data traffic after the aggregation
of all physical ports. The switch can provides up to six load balance strategy:
 src-mac
It is to share the data traffic according to the source MAC address, that is, the message with same MAC
address attributes is to get through a physical port.
