I would like to know which feature is different between Easy VSS and Traditional VSS.
I know "Easy VSS is a new way of implementing VSS by using a single command" but I cannot find more information about it.
Never done easy VSS, but one big difference is that in VSS the VLS link is layer-2, but with easy VSS, the VSL link appears to be layer-3.
Easy VSS is a simplified and automated way of configuring VSS for first time. Once a VSS is configured then it same as traditional VSS in functionality.
There is no concept of layer 2 or layer 3 VSL link. VSL is the internal portchannel link and you cannot configure as layer 2 or layer 3 portchannel.
Following is the link of Easy VSS steps.
