LACP Setup
This page allows you to enable 802.3ad Link Aggregation Control Protocol (LACP)
for the selected port.
You can configure any number of ports on the switch to use LACP. If ports on
another device are also configured for LACP, the switch and the other device will
negotiate a trunk link between them. However, before making any physical
connections, consider the following points:
• To avoid creating a loop in the network, be sure you enable LACP before
connecting the ports, and also disconnect the ports before disabling LACP.
• If the target switch has also enabled LACP on the connected ports, the trunk will
be activated automatically.
• A trunk formed with another switch using LACP will automatically be assigned the
next available trunk ID.
• All ports on both ends of an LACP trunk must be configured for full duplex, either
by forced mode or auto-negotiation.
• The ports at both ends of a trunk must be configured in an identical manner,
including communication mode (i.e., speed, duplex mode and flow control), VLAN
assignments, and CoS settings.
