\subsection[VSS]{Virtual Switch Stacking}
Activating switch stacking means you get a single control plane for all
switches in a \gls{vss} stack. The stack master switch gets to have the active
control plane. With help of \gls{sso} \& \gls{nsf} data + switch fabric is kept
in sync between stack members. This way no communication is lost when failures
\textbf{do} happen at some point.

\newpage
\textbf{Benefits} with \gls{vss} technology is
\begin{enumerate}
\item Simplified topology,
\item use of \gls{mec} to provide loop-free topology,
\item with \gls{mec} \gls{fhrp} + \gls{stp} can be avoided.
