Using an HA pair of 5508s

Having the same issue.

Using an HA pair of 5508s running 7.6.110 and CPI 1.4 update 1.

I have an active TAC case and they are not making any progress on determining the issue.  :/

This issue is now resolved.

This issue is now resolved.  In my case, my CPI was on a subnet other than the management subent that the WLC pair is on.  I also have a dynamic interface configured on the WLC that is using the same subnet as the CPI server.

I found this obscure post that showed similar symptoms:

It suggested that SNMP was not working because CPI is using the same subnet as the dynamic interface.  I can neither confirm nor deny this is the case.  However, I changed CPI's IP address to the same subnet as the WLC management interface, and the WLC registered fine.

The only other detail I can think is relevant is that there is no firewall, etc between the subnets.  Pings worked fine.  A machine on the CPI subnet could access the WLC GUI/CLI.  The two subnets were just L3 switched via our core switch and SVI interfaces.

Hope this works for you too.
