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.
