Creating Trunk Groups
You can create multiple links between devices that work as one virtual, aggregate
link. A port trunk offers a dramatic increase in bandwidth for network segments
where bottlenecks exist, as well as providing a fault-tolerant link between two
devices. You can create up to six trunks at a time.
The switch supports both static trunking and dynamic Link Aggregation Control
Protocol (LACP). Static trunks have to be manually configured at both ends of the
link, and the switches must comply with the Cisco EtherChannel standard. On the
other hand, LACP configured ports can automatically negotiate a trunked link with
LACP-configured ports on another device. You can configure any number of ports
on the switch as LACP, as long as they are not already configured as part of a static
