\subsection{VTP}
|
||||
\rfig{vtp/implementing-vtp}{VTP}\cite{vtpchap4}
|
||||
\fig{vtp/implementing-vtp}{imp-vtp1}{VTP}
|
||||
|
||||
\subsubsection{VTP Modes}
|
||||
The tree modes a VTP \textit{enabled} device can operate are
|
||||
\begin{itemize}
|
||||
\item Transparent
|
||||
\item Server
|
||||
\item Client
|
||||
\end{itemize}
|
||||
Of course you can \textit{disable} VTP altogether.
|
||||
|
||||
Key things to be aware of \textit{before} enabling VTP in your environment is to make double sure of only having 1 VTP domain. \textbf{If} 2 or more VTP domains exists. Be triple sure to separate them! As to avoid having an VTP server DB overridden with data from another VTP domain.
|
||||
|
||||
The three VTP modes \textit{operates} as follow
|
||||
\begin{itemize}
|
||||
\item Transparent
|
||||
\begin{itemize}
|
||||
\item Creates, modifies and deletes \textit{local} vlans only
|
||||
\item Forwards advertisements
|
||||
\item Does \textit{not} synchronizes vlan configurations.
|
||||
\end{itemize}
|
||||
\item Server
|
||||
\begin{itemize}
|
||||
\item Creates, modifies and deletes vlans
|
||||
\item Sends and forwards advertisements
|
||||
\item Synchronizes vlan configurations
|
||||
\end{itemize}
|
||||
\begin{itemize}
|
||||
\item Cannot create, modify or delete vlans
|
||||
\item Send and forwards advertisements
|
||||
\item Synchronizes vlan configurations
|
||||
\end{itemize}
|
||||
\end{itemize}
|
||||
|
||||
\subsubsection{VTP Announcement}
|
||||
VTP operates with announcements sent out in intervals. Summarized it amounts to
|
||||
\begin{itemize}
|
||||
\item 1 \textit{summary} announcement per 5th minute from the server
|
||||
\item The summary announcement informs clients of the current revision
|
||||
\item An announcement is sent out \textit{on the spot} when a change has been made on the VTP server
|
||||
\end{itemize}
|
||||
|
||||
Do remember it is \textbf{only} the VTP server which has the vlan configuration stored \textbf{on disk}. All device clients and transparent nodes do only store the vlans delegated by VTP in memory.
|
||||
|
||||
\subsubsection{Common Issues}
|
||||
\begin{itemize}
|
||||
\item Different/Incompatible VTP versions
|
||||
\item Wrong password
|
||||
\item Incorrect mode name
|
||||
\item No server set (all devices configured in transparent/client/vtp disabled mode)
|
||||
\end{itemize}
|
||||
|
||||
\subsubsection{VTP Versions}
|
||||
\begin{itemize}
|
||||
\item Version 1
|
||||
\item Version 2
|
||||
\begin{itemize}
|
||||
\item Version-dependent transparent mode
|
||||
\item Consistencycheck
|
||||
\item Token ring support
|
||||
\item Unrecognized type-length-value support
|
||||
\end{itemize}
|
||||
\item Version 3 (not "yet" common)
|
||||
\begin{itemize}
|
||||
\item Extended VLAN support: Allow ranges are 1-1005,1018-2095. Not mentioned vlans ranges up to 4095 is still reserved.
|
||||
\item Domain name is not automatically learned.
|
||||
\item Better security.
|
||||
\item Better database propagation.
|
||||
\item MST now supported.
|
||||
\end{itemize}
|
||||
\end{itemize}
|
||||
|
||||
\subsubsection{VTP Pruning}
|
||||
The art of only allowing the vlan traffic to flow on \textit{necessary} links.
|
||||
|
||||
This means if there are no clients in a vlan on a device. Then no traffic for the inactive vlans is send down-/upstream on the link in question.
|
||||
\fig{vtp/vtp-pruning}{vtpruning1}{VTP Pruning}
|
||||
|
||||
\subsubsection{Security}
|
||||
It is \textbf{strongly} recommended to enable the security features supported in VTP.
|
||||
|
||||
\textbf{Password:} MD5 hashing, Case-sensitive, Length between 8 and 64 chars.

||||

||||
