Engine ID
An octet string identifying the engine ID that this entry should belong to. The
string must contain an even number between 10 and 64 hexadecimal digits, but
all-zeros and all-’F’s are not allowed. The SNMPv3 architecture uses User-based
Security Model (USM) for message security and View-based Access Control
Model (VACM) for access control. For the USM entry, the usmUserEngineID and
usmUserName are the entry 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 is the same as 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 only ASCII characters from 33 to 126 are allowed.
Security Level
Indicates the security model that this entry should belong to.
Possible security models include:
NoAuth, NoPriv: no authentication and none privacy
Auth, NoPriv: Authentication and no privacy
Auth, Priv: Authentication and privacy
The value of security level cannot be modified if the entry already exists, which
means the value must be set correctly at the time of entry creation.
Authentication
Protocol
Indicates the authentication protocol that this entry should belong to. Possible
authentication protocols include:
None: no authentication protocol
MD5: an optional flag to indicate that this user is using MD5 authentication
protocol
SHA: an optional flag to indicate that this user is using SHA authentication
protocol
The value of security level cannot be modified if the entry already exists, which
means the value must be set correctly at the time of entry creation.
Authentication
Password
A string identifying the authentication pass phrase. For MD5 authentication
protocol, the allowed string length is 8 to 32. For SHA authentication protocol,
the allowed string length is 8 to 40.
Only ASCII characters from 33 to 126 are allowed.
