Port Trunking
Port Status and ConfigurationFeature
s
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:
Figure 11-5. Conceptual Example of Port Trunking
With full-duplex operation in a four-port trunk group, trunking enables the
following bandwidth capabilities:
