Configuring Dynamic Trunks
Ports configured for LACP can automatically negotiate a trunked link with
LACP-configured ports on another device.
Command Usage
• To avoid creating a loop in the network, be sure you enable LACP before
connecting the ports; also disconnect the ports before disabling LACP.
• If the target switch has also enabled LACP on the connected ports, and
port members at one or both ends of the link are set to actively initiate a
link, the trunk will be activated automatically.
• If the number of active ports (i.e., Work Ports) is less than the number of
assigned port, all the other ports will be placed in a standby mode.
Should one link in the trunk fail, one of the standby ports will
automatically be activated to replace it.
• All ports on both ends of an LACP trunk must be configured for full
duplex, either by forced mode or auto-negotiation.
• The Spanning Tree Protocol must be enabled for LACP to function
properly. (See “Configuring Global STP Settings” on page 3-34.)
