Go all the way and do consider if Supervisor Redundancy is a necessary requirement, too.

|

|
||||
\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}
