Dnac - Switch snmp auth failure on reboot

[Karl Wilson]

Hi Guys,

Has anyone experienced a switch always loosing the snmp comms on a reboot via the dnac? The settings are still present on the network switch but i have to run a re-discover to fix the communication. NCIM12006 is the error code. once i do the re-discover it fixes the problem until its upgraded/rebooted.

9300lm running 17.9.5

dnac 2.3.5.5

Hello Karl!

I had the same issue. The problem is in the switch itself and the version of the software. It's deleting the snmpv3 configuration...
