Hi guys,
yesterday I build a lab to play around with the DUR and UBT stuff in AOS-CX. So far everything was working as expected until this morning.
I did't changed the setup (and yes everything was saved properly) but the tunneling from a 6300 to an MM manged 7205 won't come up after the successfull authentication.
After some time I reconfigured the 7205 (tunnelled-node-server statement) and everything was working as expected until I rebooted the switch. After a switch reboot (reproducible) the tunnel after a successful user authentication won't come up again.
Rebooting the MD in a functional setup doesn't have any impact. The tunnel establishes after a successfull authentication.
Can anyone explain (technically) to me why this might happen? Bug? Work as designed?
Firmware:
MM and MD 8.6.0.6 (and tested with 8.5.0.4)
6300 11.05.0020 and 11.05.0001
Clearpass 6.9.3
As stated the only workaround I found is to change the "tunneled-node-server IP" on the MD and put the right IP back in.
Thanks for your help!
#6300
