AP's are trying to access mus.cisco.com

[nmoore1978]

I have multiple 1142 and 1252 access points on a 5508 controller.  I only allow Internet access to devices/users that have authenticated to Active Directory.  I'm seeing lots of traffic from my access points trying to access http://mus.cisco.com.  What is the purpose of this traffic?  I've tried searching for an answer, but I'm coming up empty.

I think this is related to anyconnect client.

Do your users in the network use anyconnect client to connect to either vpn or wireless network?
