Parameter descriptions
:
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 equals 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
1-31 characters, and the allowed content is ASCII characters 33 - 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.
