This configuration example shows you how to configure and enable a multilink trunk with LACP.
You must configure all aggregatable ports to use the same aggregator key so they can form an MLT.
The following illustration shows you an MLT created with LACP within a VLAN used to carry user traffic.
The following procedures show you how to configure both switches.
Configure the two devices to connect with MLT with LACP.
