Cisco Prime Infrastructure is a damned nightmare of browser bugs (some features work in IE8, some in IE9, and some only in Firefox). And I am not sure if what I am experiencing is a browser bug - or a real bug - or something that I was able to do before and can't any more? I would love for someone to either explain why this is happening to me, or reproduce the bug!
I'm running Prime 2.1.1. I am doing this ...
Configure > Controller Template Launchpad
System > Dynamic Interface
Select a command > Add interface (GO)
Enter all the properties - roll to the bottom of the page, and click Apply to Controllers
I have four controllers. And normally I would add an interface for each controller. But I can only create two out of the four. It doesn't matter which two I choose. When I click Add under Manage Interfaces for the third controller, I cannot click the Done button to apply it (see screenshot, attached). I have found that if I change the VLAN to something else, it will let me save it. But ... why? I went back and reviewed all of my existing interface templates and I am not doing anything different. Although, they were all created a long while ago using WCS 7.x.
Any help, guidance, or confirmation of insanity would be appreciated.
