Command Usage
â—† The ports on both ends of an LACP trunk must be configured for full duplex,
either by forced mode or auto-negotiation.
â—† A trunk formed with another switch using LACP will automatically be assigned
the next available port-channel ID.
â—† If the target switch has also enabled LACP on the connected ports, the trunk
will be activated automatically.
â—† 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.
