Hi Herman,
Thank you for the detailed response. I had been going over the ClearPass guide instead of the Instant user guide. As the instant user guide states the current version doesnt support shared locations, it sounds like it may be coming in a later version. This will be an excellent feature once the IAPs are compatible with it, I'll have to wait until then.
I had thought that when instant is integrated with CPPM, location based enforcement was possible as it states that in the Instant user guide. I might have just not understood the wording correctly.
Creating a separate L2 VLAN for it would work, but isn't currently possible. I won't be able to create a VLAN for this purpose as we have hit the maximum amount of VLANs our infrastructure can support until we make some large changes (planned throughout the coming year). I'm still waiting to deploy a few more IAP clusters but this problem is preventing that as well.
I'll either have to see how many users in that building require access to the printer, if that doesn't pass the shared users limit. Alternativley I can open it up to its cluster if my requirement isn't possible until a later unreleased version.
