Description
Check to delete the entry. It will be deleted during the next save.
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 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
the system engine ID then it is a local user; otherwise it's remote a user .
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.
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 is
paramount to ensure that the value is set correctly.
Indicates that 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 it is
paramount to ensure that the value is set correctly.
