Generally it is better to use Cisco switches as the interface is familier, works better than the web-driven rivals, they are more reliable and familiarity is worth money, unlike any other switch or router (with the exception of Juniper). | Generally it is better to use Cisco switches as the interface is familier, works better than the web-driven rivals, they are more reliable and familiarity is worth money, unlike any other switch or router (with the exception of Juniper). | ||
=== Goals === | |||
Broadly, create the VLAN, add and IP address to VLANs where needed, and move ports into the vlan. | |||
== Fix idle timeout == | |||
Looking at <i>sh line vty 0</i> around other details I can see the idle timeout is only ten minutes. I like to change it to thirty minutes to give me more thinking time and to make the notes on this page without it logging me out. | |||
<nowiki>switch>sh line vty 0 | |||

This is how I change it to thirty minutes | |||

Now the timeout is thirty minutes. | |||

== Create VLANs == | |||
Looking at the vlan setup doesn't require enable but changing it does. | |||

At this point everything is in VLAN1, which is the default configuration. However our goal here is to put ports into a relevant VLAN and turn off VLAN1. First we need to create some VLANs. Go into enable mode and conf t. | |||
