Port Trunking Overview Overview This chapter describes creating and modifying port trunk groups. This includes non-protocol trunks and LACP (802.3ad) trunks. Port Status and Configuration Features Feature viewing port trunks configuring a static trunk group configuring a dynamic LACP trunk group Default n/a none disabled Menu page 11-9 page 11-9 - CLI page 11-11 page 11-15 Web page 11-17 - page 11-15 - Port trunking allows you to assign up to eight 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 backbone devices as well as to connections in other network areas where traffic bottlenecks exist. A trunk group is a set of up to eight 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: The multiple physical links in a trunk behave as one logical link Switch 1: Ports c1 - c3, c5 - c7, and c9 - c10 configured as a port trunk group. port c1 port c2 port c3 port c4 port c5 port c6 port c7 port c8 port c9 port c10 ... port n port 1 port 2 port 3 port 4 port 5 port 6 port 7 port 8 port 9 port 10 port 11 port 12 ... port n Switch 2: Ports a1, a3 - a4, a6 - a8, a11, and a12 configured as a port trunk group Figure 11-1. Conceptual Example of Port Trunking With full-duplex operation in a eight-port trunk group, trunking enables the following bandwidth capabilities: 11-2
