Engine ID
An engine ID is used to uniquely identify an SNMP engine. Because each SNMP entity includes only one SNMP engine, one
SNMP engine uniquely identifies an SNMP entity in a management domain. Therefore, the SNMPv3 agent as an entity must
has a unique engine ID, that is, SnmpEngineID.
An engine ID is an octet string that consists of 5 to 32 bytes. RFC3411 defines the format of an engine ID:
The first four bytes indicate the private enterprise ID (allocated by IANA) of a vendor, which is expressed in
hexadecimal.
The fifth byte indicates remaining bytes:
0: Reserved.
1: The later four bytes indicate an IPv4 address.
2: The later 16 bytes indicate an IPv6 address.
3: The later six bytes indicate a MAC address.
4: Text consisting of 27 bytes, which is defined by the vendor.
5: Hexadecimal value consisting of 27 bytes, which is defined by the vendor.
6-127: Reserved.
128-255: Formats specified by the vendor.
