all monitored servers critical alert with message: authentication failure

Hi,

Thanks for your post!

When an SNMP agent receives a request that does not contain a valid community name or the host that is sending the message is not on the list of acceptable hosts, the agent can send an authentication trap message to one or more trap destinations (management systems). The trap message indicates that the SNMP request failed authentication. This is a default setting which can be turned off on the managed node or the VM's.

To know more about this trap and the steps to fix it, please refer OME FAQ item #10.2 (Misc section) located below:

Hope this helps!

thanks shivendra,

I will try this out.

regards,

Sean

Hi Shivendra,

if I checked the Send authentication trap box, but I do have the accepted community name configured to my OME, and accept SNMP packets from the OME hosts, will I still get authentication failure alerts from OME 2.2 ? if so , what is the reason for this alert ? thanks

Hi Sean,

If SNMP community name configuration is made correct in OME for target systems, the authentication failure alerts should not arise. Also note that the community name is case-sensitive, please make sure this is not the case with your setup.
