\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.
