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.
Aggregation / Trunking Configuration
To assign a port to a trunk, click the required trunk number, then click Apply.
