Trunk Setup 13-1
Chapter 13
Trunk
Setup
This chapter shows you how to logically aggregate physical links to form one logical, higher-bandwidth
link.
13.1 Introduction 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.
