ONFIGURATION

This section describes how to configure static and dynamic trunks.

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 13 trunks on the

switch, or up to 32 across the stack.

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 trunk. If

ports on another device are also configured as LACP, the switch and the

other device will negotiate a trunk link between them. If an LACP trunk

consists of more than eight ports, all other ports will be placed in standby

mode. Should one link in the trunk fail, one of the standby ports will

automatically be activated to replace it.
