4.1.4 Aggregation
Port trunk allows multiple links to be bundled together and act as a single physical link for
increased throughput. It provides load balancing and redundancy of links in a switched
internetwork. Actually, the link does not have an inherent total bandwidth equal to the sum of
its component physical links. Traffic in a trunk is distributed across an individual link within the
trunk in a deterministic method called a hash algorithm. The hash algorithm automatically
applies load balancing to the ports in the trunk. A port failure within the trunk group causes the
network traffic to be directed to the remaining ports. Load balancing is maintained whenever a
link in a trunk is lost or returned to service.
Aggregation / Trunking Configuration
To assign the ports to a trunk, click the required trunk number ports, then click Apply.
The below example shows that Ports 3 and 4 are the member ports of Trunk Group 1.
4.1.5 LACP
IEEE 802.3ad Link Aggregation Control Protocol (LACP) increases bandwidth by automatically
aggregating several physical links together as a logical trunk and providing load balancing and
fault tolerance for uplink connections. Once the port is configured as a Static Aggregation port,
the area will become gray. It means a port can only be a member of the Aggregation or LACP.
LACP Port Configuration
 Port: The port ID.
 Protocol Enabled: Enables LACP Protocol on the associated port.
 Key Value: Configures a port's LACP administration key. The port administrative key must
be set to the same value for ports that belong to the same link aggregation group (LAG). If
