SNMPv3 is the only version that supports authentication.


ACL related problems would deny traffic.  You would not see an AUTHFAIL if the ACL was a problem.

the community strings are valid.

You cannot configure SNMP authentication on SNMPv2 and below

Only option to support authentication failures is to update to SNMP v3
