When using the \texttt{'static'} method like in the example, the options \texttt{ipaddr} and
\texttt{netmask} are mandatory, while \texttt{gateway} and \texttt{dns} are optional.
+You can specify more than one DNS server, separated with spaces.
+
DHCP currently only accepts \texttt{ipaddr} (IP address to request from the server)
and \texttt{hostname} (client hostname identify as) - both are optional.
The CPU port defaults to tagged, all other ports to untagged.
On Broadcom hardware the CPU port is always 5. The other ports may vary with
different hardware.
+
+For instance, if you wish to have 3 vlans, like one 3-port switch, 1 port in a
+DMZ, and another one as your WAN interface, use the following configuration :
+
+\begin{Verbatim}
+config switch "eth0"
+ option vlan0 "1 2 3 5*"
+ option vlan1 "0 5"
+ option vlan2 "4 5"
+\end{Verbatim}
