I am not new to IT, but in the past, I've always had a Network Admin to handle this type of stuff. That being said I know just enough to be dangerous.
What I have is an old hodgepodge of different technologies that were all purchased before my time and thrown in together with a wish and a prayer. Now I'm trying to make sense of it all and make it better for our users and myself.
I'm not sure what information you will need to assist me but I'll provide as much as I am able, if I've missed something that would help in figuring this out let me know and I'll update the question.
We currently have:
9 UniFi Network UAP-AC-Pro Gen2
They have 2 working SSIDs both on the same business network, a Management SSID that is supposed to be on a separate network, and a Guest SSID that is supposed to be on yet another network. All 4 SSIDs are on the same network.
6 Extreme Networks WiNG Wireless AP8432
They all have 1 SSID, it is on the same network as the UniFi APs and should be as they are mirroring one of the 2 SSIDs that are working.
1 Extreme Networks Universal Wireless AP305C
This matches the other 6 from Extreme it was purchased more recently and was cheaper than the new version of the WiNG Wireless APs.
1 Aruba IAP-207
This has 3 SSIDs, and they all work. 1 business, 1 manager, and 1 guest are all separate networks controlled by the AP itself.
These are all connected to various switches throughout the plant.
There are:
- Cisco C2950
- Extreme X440G2
- Extreme 210
- HP ProCurve 1800 / 1820
- Plus a bunch of unmanaged 5-24 port switches mostly Linksys and D-Link
Networks: Just 1 business network. No subnets, no VLANs.
We are running out of IPs very quickly and I would like to alleviate the stress by creating a separate subnet or network or VLAN (or something) for different things like printers and cameras.
It seems like it should be simple enough, but I can't afford to break our network.
EDIT
Sorry I was not clear in the original question. I want to know how to create a subnet. I have used a subnet calculator that made it seem like I can create any number of subnets, but I don't know how to actually create them or where.
So my questions are:
- How and where do I create the subnet?
- How do I ensure that the subnets can communicate so that when I move printers to it we can still print?
- I have a Cisco 2950 and a Cisco 2950sx switch, they are both old and only 10/100, is that good enough to create the subnet? Or do I need something better, like a switch with 1g speed since that is what the rest of the network is using?
EDIT 2 Network Diagram
Hopefully, this helps. I am trying to show how much stuff is jumbled together. There are a bunch of different things connected to each switch, laptops, desktops, printers, AP, Cameras, unmanaged switches, some lab equipment too. I just put this together now because we don't have one otherwise.
Is this enough detail?
Current IP Address ranges:
- 10.0.0.1-99 set aside for static assignment(5 remaining)
- 10.0.0.100-254 DHCP address pool (10-40 remaining depending on personal devices on the network)
- 10.0.1.1-254: Lab Intranet not connected to the business network or internet. This isn't really a subnet because it's not connected to anything else, but I don't want to use this IP range in making a subnet so there isn't any confusion later.
I would like to add subnets:
- 10.0.2.1-254 for printers
- 10.0.3.1-254 for cameras
- 10.0.4.1-254 Guest Wi-Fi access
If you could explain how to set up the first one for the printers I can then go off of that to create the others.
EDIT 3 - Network Explanation
We have just one network. We have 4 types of AP from 3 different brands.
- The Extreme APs (both types) are only broadcasting one SSID. This SSID is used for Mobile Device Scanners that connect to our ERP system.
SSID: WMS
- The Aruba AP has 3 SSIDs, including the same one as the Extreme APs.
SSIDs: WMS, Management, Guest
The SSIDs WMS and Management are on the same network they are just different names, there isn't really a reason for this other than it was like that when I got here and I've not fixed it yet.
The SSID Guest uses Aruba's built-in client management system in the virtual controller to grant a separate IP range. It appears to be using 10.0.10.1-254 as its built-in range.
- Unifi APs, have 2 SSID (the guest SSID doesn't work because there's no VLAN for it to use so it's currently turned off till I get this figured out.) They are the same 2 as Aruba and are on the same network with the same IP range.
SSIDs: WMS, Management
The SSIDs WMS and Management again there isn't really a good reason for these to be separate since the only difference is the name of the SSID.
EDIT - Add Firewall
The firewall we have is a FortiGate 60F. This is managed by our parent company in another country.
