Hi,
I have a job that runs every day in NCM to update the inventory.
After upgrading my Cisco devices to use SNMP version 3 I noticed this error message in my device logs:
%SNMP-3-AUTHFAIL: Authentication failure for SNMP req from host 10.w.x.y
Because of the times of these errors I quickly identified that the daily inventory job was the cause and by further trial and error I have identified that the 'IP Addresses' tick box under the Inventory settings tab was the specific cause.
I am assuming that the MIB objects being interrogated (as a result of the "IP Addresses" tick box) are out of the scope of the MIB tree allowed by my SNMP v3 setup.
I have allowed read only access to a view which includes the 'Internet' MIB object:
snmp-server view V3Read internet included
I seem to have 2 choices to stop the error messages. 1. Untick the box, or 2. add a MIB object to my view.
If I do 1. I'm not sure if the inventory will lose some functionality.
If I do 2. how do I identify what MIB name I should use which maps to the "IP Adresses" tick box?
Many thanks,
Andy.
