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.
SNMP v3 configuration examples
The examples below shows how to configure SNMP v3.
