1.1.2 High Performance Switching Example
The Switch is ideal for connecting two geographically dispersed networks that
need high bandwidth. In the following example, a company uses the optional 10
Gigabit uplink modules to connect the headquarters to a branch office network.
Within the headquarters network, a company can use trunking to group several
physical ports into one logical higher-capacity link. Trunking can be used 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.
