Port Status and Configuration Features
Port trunking allows you to assign up to four physical links to one logical link
(trunk) that functions as a single, higher-speed link providing dramatically
increased bandwidth. This capability applies to connections between back-
bone devices as well as to connections in other network areas where traffic
bottlenecks exist. A trunk group is a set of up to four ports configured as
members of the same port trunk. Note that the ports in a trunk group do not
have to be consecutive. For example:
