The ports on both ends of an LACP trunk must be configured for full

duplex, either by forced mode or auto-negotiation.

A trunk formed with another switch using LACP will automatically be

assigned the next available port-channel ID.

If the target switch has also enabled LACP on the connected ports, the

trunk will be activated automatically.

If more than eight ports attached to the same target switch have LACP

enabled, the additional ports will be placed in standby mode, and will

only be enabled if one of the active links fails.

The following shows LACP enabled on ports 10-12. Because LACP has also

been enabled on the ports at the other end of the links, the
