+\subsection{Channel Bundling (aka. EtherChannel, PortChannel)}
+Channel bundling is the "art" of using multiple physical links as one single logical link in when viewed from the perspective of the forwarding plane.
 
+Technologies:
+\begin{itemize}
+    \item \textbf{PAgP:} The Cisco-only thingy
+    \item \textbf{LACP:} The IEEE standard
+    \item \textbf{Static:} Just forced on
+\end{itemize}
+
+\fig{channelbundling/network-without-channelbundling}{noethernetchannel}%
+{No Channelbundling present}
+
+Channel bundling of switch ports in the network may or may not be the best idea, in regards to the networks growth rate in terms of min. required bandwidth.
+
+Channel bundling spreads out the in and egress flows based upon one of several methods configured on the switch:
+\begin{itemize}
+    \item Source to Destination MAC
+    \item Source to Destination IP
+\end{itemize}
+Keep in mind this will by no means archive true load balancing. Where all links are equally used based upon number of flows \textit{or} in terms of used bandwidth.
+
+\fig{channelbundling/network-with-channelbundling}{withethernetchannel}%
+{Channelbundling present}
+
+\subsubsection{Protocol Properties}
+
+\begin{itemize}
+    \item LACP
+    \begin{itemize}
+        \item Active: Enabled
+        \item Passive: Waits for LACP packets on the wire before enabled
+    \end{itemize}
+    \item PAgP
+    \begin{itemize}
+        \item Desirable: Enabled
+        \item Auto: Waits for PAgP packets on the wire before enabled
+    \end{itemize}
+\end{itemize}
+
+Some other \underline{required} settings to be (equal across all ports) aware of when configuring Channel bundling are
+\begin{enumerate}
+    \item Port speeds
+    \item Duplex mode
+    \item Configured vlan ranges
+\end{enumerate}

 \section{Spanning Tree}
 
-\subsection{STP}
+Spanning Tree exists for the \textbf{sole} reason to save "your" network and all the broadcast storms an network engineer having a bad day can by mistake create!
-\subsection{PVST}
-\subsection{RPVST+}
-\subsection{MTP}
 
+STP comes from the above desire where redundancy was wanted but no protocol existed before STP to help in this regard.

+\subsection{Port Roles}
+
+When a switch is enabled for Spanning Tree. One of the following roles will have been assumed by any port on the switch in question.
+
+\begin{itemize}
+	\item \textbf{Root port:} Only 1 port on any switch (non-counting the root bridge!). Is always the port with the lowest metric (aka. best path) to the root bridge.
+	\item \textbf{Designated port:} A designated port is the port on any segment closest to the root bridge and forwarding traffic.
+	\item \textbf{\textit{Non}-designated port:} Put in blocking mode and not currently forwarding traffic.
+	\item \textbf{Disabled port:} The port has been one-way-or-another shut down.
