CHAPTER 9
Trunking
This chapter shows you how to logically aggregate physical links to form one
logical, higher-bandwidth link.
9.1 Trunking Overview
Trunking is the grouping of physical ports into one logical higher-capacity link. You
may want to trunk ports if for example, it is cheaper to use multiple lower-speed
links than to under-utilize a high-speed, but more costly, single-port link.
However, the more ports you aggregate then the fewer available ports you have. A
trunk group is one logical link containing multiple ports.
9.1.1 Distribution Criteria
The Switch uses a traffic distribution algorithm to balance traffic between trunk
members. The Switch allows you to specify what criterion it should use to
calculate the most efficient distribution of traffic. The choices are Source MAC
Address (SA), Destination MAC Address (DA) or both (SA + DA). The best choice
of distribution criteria depends on your specific network environment.
