Trunk Setup

This chapter shows you how to logically aggregate physical links to form one logical, higher-bandwidth link.

13.1Introduction to Trunking

Trunking (link aggregation) is the grouping of physical ports into one logical higher-capacity link. You may want to trunk ports 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.

However, the more ports you aggregate then the fewer available ports you have. You may configure up to four trunk groups in the ES-3024. A trunk group is one logical link containing multiple ports.

Ports should be physically linked in consecutive order without gaps when forming trunk groups. For example ports 9, 10, 11 and 12 in switch 1 should connect to ports 1, 2, 3 and 4 in switch 2 to form one trunk group; ports 9, 10, 11 and 12 in switch 1 connected to ports 1, 3, 2, 4 in switch 2 would form two trunk groups, not one.

	Table 13-1 Trunk Groups
TRUNK GROUP		BEGINNING-TO-END PORT RANGE
T1		1 to 8
T2		9 to 16
T3		17 to 24
T4		25 and 26 (the uplink ports)

See also the Switch Setup chapter for information on dynamic link aggregation using the Link Aggregation Control Protocol (LACP). The ES-3024 adheres to the 802.3ad standard for static and dynamic (LACP) port trunking.
