\section{Network Nodes}
\begin{center}
Cisco proposes \textbf{StackWise for Access} and \textbf{\gls{vss} for Aggregation} Layer modules.
\end{center}
Go all the way and do consider if Supervisor Redundancy is a necessary requirement, too.
\fig{vss/vss}{vss}{2 common ways of doing cabling in switch stacking}
\subsection{StackWise}
\textit{Per the usual} a Cisco proprietary technology doing the following stuff \footnotesize{not necessarily} in the order specified:
\begin{itemize}
\item Stacking the switches as one logical unit
\item Stacking the switches as one logical unit\footnote{Up to 9 switches can be stacked together}
\item A switch can be added/removed from an operational stack without affecting performance
\item Configuration is shared by every stack member
\item Routing information is shared by every stack member
\item The stack is always managed as one single logical unit. All the normal day-to-day operations on the CLI/SNMP Agents/Integrated web server is made to the management \gls{ip}.
\item The switches run a modified protocol to communicate all things from the master switch to the slaves and vice-versa.
\item New switches are automatically brought up to speed with the operating software from the master node in the stack and will be ready to operate after plug-and-play operation is finished.
\item Channel bundling can be performed with member ports across the whole stack. Say 4 ports each in port TenGigE x/1 in member switch 0-3. Now its a 4x10G Channel.
\item We can avoid \glspl{stp} internally on the stack as a whole. \textit{Yes}. Fever Layer 2 loops and/or errors.
\end{itemize}
\textbf{\gls{cli}}
\begin{itemize}
\item View members of stack: \cliline{show switch}
\item View members status of stack ports: \cliline{show switch stack-ports}
\end{itemize}
