Usage Information
LACP on the VLT ports (on a VLT switch or access device), which are members of the virtual link trunk, is not
brought up until the VLT domain is recognized on the access device.
To ungroup the VLT and port-channel congurations, use the no lacp ungroup member independent command on
a VLT port channel, depending on whether the port channel is VLT or non-VLT.
