Technical Tip: How to check Engine ID OID for WAF

The Engine ID is a unique identifier for each SNMP entity, and it helps to ensure that the communication is done with the correct device.  Without unique Engine IDs, there could be potential for security breaches or miscommunication.

This feature was introduced in SNMPv3 only. The length can range from 10-64 characters which can correspond to 5-32 bytes.

The first 4 bytes are vendor-specific, in this case, Fortinet (8000304404).

• Engine OID is basically the combination of the prefix (8000304404) followed by the hex of the serial number of the device.
• Engine OID can be found under snmpv3 trap packets.

To receive the traps, a trap receiver must have Engine ID configured, else the traps will be dropped.
