Some SNMP utilities using SNMPv3 require that an snmpEnginID be provided for the target system. Messaging Gateway does not expose the SNMP Engine ID in the GUI when SNMPv3 is enabled so the system must be directly queried to get the snmpEngineID value.

Resolution
The OID for the snmpEngineID.0 value is 1.3.6.1.6.3.10.2.1.1.0
The snmpEngineID.0 value can be extracted from SMG by running the following command from any linux system with snmpget installed. Details for the user, hashAlgorithm, password, and hostname will depend on how SMG is configured in Administration > SNMP > Versions
snmpget -v3 -l authNoPriv -u [username] -a [hashAlgorithm] -A [password] -X [password] [hostname] 1.3.6.1.6.3.10.2.1.1.0
For example:
snmpget -v3 -l authNoPriv -u admin -a SHA -A password -X password smg 1.3.6.1.6.3.10.2.1.1.0 iso.3.6.1.6.3.10.2.1.1.0 = Hex-STRING: 80 00 1F 88 80 C7 65 DD 41 1C 3D DA 5E 00 00 00 00
