Interpreting varbinds in report packets

If an SNMP version 3 request packet is to be rejected by an SNMP agent, the agent sends a report
packet that contains one or more varbinds. The varbinds contain additional information, showing
the cause of failures. An SNMP manager application decodes the description from the varbind. The
following table presents a list of varbinds supported by the SNMP agent.

authNoPriv

Displays if the security model shows v3 and user
authentication is by user name and the MD5 or SHA
algorithm.

authPriv

Authentication uses MD5 or SHA. Encryption uses DES and
AES protocol.
