SNMP Engine ID
The engine ID is designed to identify an SNMP engine uniquely. Every SNMP
entity contains a SNMP engine, a SNMP engine ID identifies a SNMP entity in a
management domain. So every SNMPV3 entity has a unique identifier named
SNMP Engine ID.
The SNMP Engine ID is an octet string of 5 to 32 bytes, which is defined in
RFC3411:
 The first four bytes indicate the private enterprise number of an enterprise
(assigned by IANA) in hex system.
 The fifth byte indicates how to identify the rest bytes.
