Engine ID
An octet string identifying the engine ID that this entry should belong to. The string must contain an even
number (in hexadecimal format) with number of digits between 10 and 64, but all-zeros and all-'F's are
not allowed. The SNMPv3 architecture uses the User-based Security Model (USM) for message security
and the View-based Access Control Model (VACM) for access control. For the USM entry, the
usmUserEngineID and usmUserName are the entry's keys. In a simple agent, usmUserEngineID is
always that agent's own snmpEngineID value. The value can also take the value of the snmpEngineID of
a remote SNMP engine with which this user can communicate. In other words, if user engine ID equal
system engine ID then it is local user; otherwise it's remote user.
User Name
A string identifying the user name that this entry should belong to. The allowed string length is 1 to 32,
and the allowed content is ASCII characters from 33 to 126.
Security Level
Indicates the security model that this entry should belong to. Possible security models are:
NoAuth, NoPriv
: No authentication and no privacy.
Auth, NoPriv
: Authentication and no privacy.
Auth, Priv
: Authentication and privacy.
The value of security level cannot be modified if entry already exists. That means it must first be ensured
that the value is set correctly.
Authentication Protocol
Indicates the authentication protocol that this entry should belong to. Possible authentication protocols
are:
None
: No authentication protocol.
MD5
: An optional flag to indicate that this user uses MD5 authentication protocol.
SHA
: An optional flag to indicate that this user uses SHA authentication protocol.
The value of security level cannot be modified if entry already exists. That means must first ensure that
the value is set correctly.
