I've noticed that as of Secure Client (AnyConnect) 5.x I get an error at the ASA CLI and ASDM when I try to change the Linux web-deployed AnyConnect client version. I have no issues with Windows or macOS AnyConnect clients. I've confirmed on ASA5585-...

After upgrading our 9800 WLC to 17.9.2, Prime has started indicating that the Coral connection is down. It was fine in 17.6.x. Prime is 3.10.2 with all of the latest patches. As far as I have been able to determine the actual telemetry stream is fine...

I've noticed that Prime doesn't seem to know when an AP connected to a 9800 WLC disconnects and reconnects. If the AP stays offline for a long time (Several hours) Prime eventually discovers this, and generates an alarm. As if there is a background j...

Howdy, I wanted to share an interesting issue with 2802 APs. I completed an upgrade to 8.3.140.0 and found that many of our 2802s did not return to operation. After a bit of tinkering and bouncing ports I found that the ones that were down were all...

Well that's strange, 3.10.4 fixed my issue. I'm also fully patched and not seeing a problem. Since they changed the syntax of the command they're using to "VRF aware", is there any chance you are using VRF on the 9800?

Another solution is to enable DHCP required. I'm unsure of why it makes a difference, but that's the one I went with. Seems to do the trick. I'm surprised that there aren't more complaints of this issue.

3.10.4 was released last week. I confirmed that it fixes the issue. They changed to the new VRF aware syntax: show telemetry internal protocol cntp-tcp manager PrimeInfrastructure_IP 20830 source-vrf 0 WLC_MGMT_IP
