I have a crazy problem going on and I cannot seem to figure this out. I have 2 HP controllers MSM760’s Teamed and about 194 HP msm410 access points. I currently have 3 VSCs (guest, BYOD, Managed). Yesterday one of the controllers supposedly locked up according to the new guy and he restarted both controllers because they are teamed and that’s what we have done in the past. After they restarted one of our campuses show red X’s on the access points. I can ping the AP’s so they are there but not showing up on the controller. Under controlled access points we have groups set up and each group represents a campus and when I select the group in question (Fry Campus) The first tab is discovered AP’s none of the Aps show up. When I select the configured Aps tab they all Say not detected and have red X’s by them. I CAN ping these Access Points. Now I was over at that campus and decided to plug one of the AP’s into a different port with a different VLAN and to my surprise it showed up on the controller and synchronized like nothing was wrong. Now that to me seems like a VLAN issue but I’ve been through the configs on the campus switches and I took my laptop over and plugged into the port where the AP was at before and I got internet access so I am completely lost. It seems now that the quick fix would be to create a new VLAN for the Access Points and go on but I would rather solve this issue. Any help ideas or simply a shove in the right direction would be greatly appreciated. I can post screen shots if needed.
