Hello experts,
I am facing an issue. We have 2 x c9800-40 in SSO and added into the DNA Center. They are also part of our SDA fabric, running many SSID's as fabric WLANs.
Since many days the c9800's are stuck in "partial collection failure" on the DNA Center, we first had an issue with netconf that is solved now, but I really don't get it. DNAC can access over SSH to the 9800s, when running a discovery on the DNA Center there is no problem, but the device still remains in "partial collection failure"...
We just added a new c9800-CL to the DNA Center to make N+1 redundancy with the SSO cluster, and we had no issues.
Did someone face a similar issue ?
c9800 are in the latest IOS version : 16.12.01s.
Thank you,
Alex
