Deploy ISE onto Proxmox
I'm starting to dive into the world of ISE because I may potentially have a project involving deploy DNAC and ISE soon. To get better at this I wanted to actually use it and try it out. I don't have an ESXI license (Thanks Broadcom!) The first step you want to do is head over to https://software.cisco.com/download/home. I work at a Cisco partner so I am able to download images from them. I am not 100% sure if this is required but I am pretty sure it is. Next thing you want to do is search for Identity Services Engine and download version 3.4. This will probably take awhile.
Once you have installed this onto your computer you have to upload the .iso image to Proxmox. For some reason, Proxmox doesn't like when you try to do this through there interface with things over 5GB so I recommend using something like FileZilla. Point the FileZilla client to the IP of your Proxmox host and use the corresponding info.
Copy the ISE .iso file over. Once you are done go back to the Proxmox web interface. Now go to your Proxmox data center and click "Create a VM"
For general, just set the name of the host. Next is OS, all you need to do is choose the iso file you uploaded. After OS is system, don't change anything there. Under disk for disk size is where it can get a little complicated. Depending on what you do, you may need more. I used 400GB to my local-lvm storage. For CPU, since this is a small appliance I am assigned 2 socks and 8 cores and setting the type to host. For memory, I set it to 32 GB and lastly network I didn't change anything since I have everything running in the same subnet. After this confirm and boot your VM.
This next step takes awhile, for me it took about 20 minutes and you know it's ready when you see this screen:
For login, use the word setup
Configure all of these settings to your liking, once you enter the password again ISE will start to boot up. Once this is all complete go to the static IP you set and login! All good to go. This whole process takes awhile it took me about 2 hours and you get a 90 day evaluation license. To renew this just reinstall ISE, if you want to save what you have setup you will need to create a backup before doing this. I may make a post on that in the future.
