I've been tasked with drawing a layer 2 network map of our very small datacenter network.
There is one 1841 cisco router, two 3560 cisco catalyst switches and 4 solaris sunfire T-1000 boxes.
I have logged in to the cisco boxes and downloaded the running configuration files for all 3. I have also gotten the output of ifconfig -a for the 4 solaris boxes.
my question is: what reading/learning should I do now to put it all together? Any tips?
I was looking at tools such as lanmap2 but that is for linux, not SunOS and I don't know if I could recompile it successfully myself.
I understand intermediate networking, but I'm not a routing guy. I know a VLAN is a way to segregate groups of ports in different switches in their own subnetworks and I hear that a trunk is a connection between two routers that conveys VLAN information but that's the extent of my knowledge on those two topics.
Answer
This answer includes a simple LAN diagram that could serve as a template for your network; note that the colors (green / pink / orange) indicate different vlans.
Typically you want to include details like switch / router port numbers, vlan information, IP addressing / netmask, hostnames, and the port name of the interface on the server.
If you don't have a copy of Visio, you can use Inkscape to generate drawings. If you are adventurous, you can even build inkscape-compatible copies of Cisco's networking icons
