I am running Prime Infrastructure (188.8.131.52.132) along side Mobility Services Engine (184.108.40.206) which are reporting all clients as not moving for the past 5 days. Has anyone had this issue at all, if so is there a known bug? We have 10 x 5520 wireless LAN Controllers servicing 4179 Access Points (2600, 3700, 3800, 1800, 1700, 3500 series AP's) and over 10,000 clients, over quite a few geographical sites. This issue has only just raised its head, an as we are using Nervecentre using (7925, 7926, 8821) Wireless IP phones in place of our bleep system, it is becoming more critical to know where Wireless IP Phones are and have been. Any help would be very welcome.
