Trunking
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 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 a port to a trunk, click on the required trunk number, then click

Link Aggregation (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.
LACP Port Configuration
Port: Port number.
Enabled: Enables LACP on the associated port.
Key Value: Configures a port's LACP administration key. The port administrative key should be set to the
same value for ports belonging to the same link aggregation group (LAG). If this administrative key is not
set when an LAG is formed (i.e., it has the null value of 0), this key is automatically set to the same value
as the one used by the LAG.
