Description: SNMP Engine ID.
What is snmpEngineID?
snmpEngineID is a read-write string (up to 64 characters) holding the unique SNMPv3 engine identifier for the Unity PDU, which SNMPv3 uses to compute per-device authentication and privacy keys. Because the engine ID is part of the key-derivation process, an NMS must know this value to properly key its localized SNMPv3 credentials for that specific PDU. For example, when scripting a bulk deployment of SNMPv3 credentials, an admin might read snmpEngineID from each PDU to correctly derive per-device keys rather than reusing one static ID across units.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.30932.1.1.2.73 snmpwalk -v2c -c public <target> CPI-UNITY-MIB::snmpEngineID
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.30932.1.1.2.73.1 snmpget -v2c -c public <target> CPI-UNITY-MIB::snmpEngineID.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.30932.1.1.2.73.1 s <value>
