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.
