4.22 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 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. This switch may use
Port ID, Source MAC Address, Destination MAC Address, or a combination of Source MAC
Address and Destination MAC Address to be the selection for Trunk Hash Algorithm. Traffic
pattern on the network should be considered carefully before applying it. When a proper
hash algorithm is used, traffic is kind of randomly decided to be transmitted across either
link within the trunk and load balancing will be seen.
This managed switch supports two trunk group, each trunk consists of 2~4 ports. Trunk
hash algorithm can be selected according to 4 different methods.
