What is port trunk?
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. The link does not have an inherent total bandwidth equal to the sum of its component physical links. Instead, traffic in a trunk is distributed across an individual link within the trunk in a deterministic method, so-called a hash algorithm. Traffic pattern on the network should be considered carefully. When a proper hash algorithm is used, traffic is randomly decided to be transmitted across either link within the trunk and load balancing will be seen.
