Wireless station events vs NAC guest portal

[James_A]

Does anyone remember something about a problem with wireless station events being sent to NetSight (where they show up in end-system events) affecting the guest portal? I thought I remembered reading something about this as being the possible cause of a problem where guests get an error from NAC instead of the registration page, but I can't find anything in my searches.

We've seen very sporadic errors pop up, instead of the registration page, for years and have never been able to figure out the cause. The issue always appears to resolve itself quickly and we can almost never reproduce it. I don't recall ever seeing a post about what you're referring to, but now you have me curious.
