Add New Entry
Setting 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: 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.
