Object Description
Delete
Check to delete the entry. It will be deleted during the next save.
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: None authentication and none privacy.
Auth, NoPriv: Authentication and none privacy.
Auth, Priv: Authentication and privacy.
The value of security level cannot be modified if entry already exist. That means
must first ensure that the value is set correctly.
Authentication
Indicates the authentication protocol that this entry should belong to. Possible
