Day 3 of our network upgrade - VLANs

Today I just went through and planned out our IP scheme. Like I mentioned before each floor will be it's own VLAN network. Here is how they will be configured;

16th floor VLAN IP
IP scheme 10.100.16.x / 24
Gateway 10.100.16.1

15th floor VLAN IP
IP scheme 10.100.15.x / 24
Gateway 10.100.15.1

14th floor VLAN IP
IP scheme 10.100.14.x / 24
Gateway 10.100.14.1

4th floor VLAN IP
IP scheme 10.100.4.x / 24
Gateway 10.100.4.1

3rd floor VLAN IP
IP scheme 10.100.3.x / 24
Gateway 10.100.3.1

A lot to think about and thanks to EIGRP that takes care of most of it :D

I ran some test on printers and plotters as well (we do a ton of that here) just to be sure that the print servers in one VLAN can communicate with the printers/plotters on another VLAN. We all know it works but you don't want any surprised come cutover time. This is why we test and test and test some more.

On cutover day I have a lot of sensitive work to do. I need to change my netmask from /16 to /24 that means I need to get to all my servers and firewall objects and SAN devices. Those are critical. These are some of things an MIS has to worry about. Yes worry and stress to the point were you almost crap your pants. You ever get those feelings? LOL!
