Chapter 3: Software Description
3.2.4 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 inter-network. 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 that
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.
3.2.4.1 Aggregation / Trunking Configuration
To assign a port to a trunk, click the required trunk number, and then click
“Apply.”

3.2.5 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.
3.2.5.1 LACP Port Configuration
• Port: The port number.
• Enabled: Enables LACP on the associated port.
