Have just deployed a bunch of 20 IAP225 that is using Clearpass for the authentication. The customer is reporting that connectivity is lost on Windows devices, with the yellow exclamation, and connection to exchange server lost. This happens about 2 minutes after connecting and will last about a min or so, but it keeps happening every 3-5 mins.
I don't have direct access to troubleshoot, but here are a couple of things on how it is configured.
- vlan is static with gateway being the core switch.
- 80 MHz channels enabled (not sure what band users connected on though)
- client-match enabled
- 802.11r enabled
- RFC3576 enabled on auth-server profile with accounting mode as 'authentication'.
I will be troubleshooting this with the customer further and looking at access tracker on Clearpass as well. Normally I would put this sort of thing down to their own network, but this is my first IAP225 with Clearpass so I'm keeping an open mind.
I'm thinking to disable client-match to see how it looks then as well.
Has anyone else had issues such as this or any suggestions?
Thanks
