Chapter 38 Configuring Port Aggregation
38.1 Overview
Link aggregation, also called trunking, is an optional feature available on the Ethernet switch and is used with
Layer 2 Bridging. Link aggregation allows logical merge of multiple ports in a single link. Because the full
bandwidth of each physical link is available, inefficient routing of traffic does not waste bandwidth. As a result,
the entire cluster is utilized more efficiently. Link aggregation offers higher aggregate bandwidth to traffic-heavy
servers and reroute capability in case of a single port or cable failure.
Supported Features:
Static aggregation control is supported
Bind a physical port to a logical port, regardless whether they can actually bind to a logical
port.
Aggregation control of LACP dynamic negotiation is supported
Only a physical port that passes the LACP protocol negotiation can bind to a logical port.
Other ports won’t bind to the logical port.
Aggregation control of LACP dynamic negotiation is supported
When a physical port is configured to bind to a logical port, the physical port with LACP
negotiation can be bound to a logical port. Other ports cannot be bound to the logical port.
Flow balance of port aggregation is supported.
After port aggregation, the data flow of the aggregation port will be distributed to each
aggregated physical port.

38.3 Port Aggregation Configuration Task
38.3.1 Configuring Logical Channel Used to Aggregation
You should establish a logical port before binding all the physical ports together. The logical port is used to
control the channel formed by these binding physical ports.
Use the following command to configure the logical channel:
Command Description
interface port-aggregator id
Configures aggregated logical channel.
38.3.2 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
