SNMP- SNMPv3 Users Configuration
Configures SNMPv3 user table. The entry index keys are Engine ID and User Name.
Figure 9-3: SNMPv3 User Configuration
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-Fs are not allowed. The SNMPv3 architecture uses the User-based secondsurity 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 agents 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 its 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.
secondsurity 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.
Authentication Protocol
- Indicates the authentication protocol that this entry should belong to.
Possible authentication protocols are:
•
None:
No authentication protocol.
•
An optional flag to indicate that this user uses MD5 authentication protocol.
•
An optional flag to indicate that this user uses SHA authentication protocol. The
value of the security level cannot be modified if an entry already exists. That means must first
ensure that the value is set correctly.
Authentication Password
- A string identifying the authentication password 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. The allowed content is ASCII characters from 33 to 126.
Privacy Protocol
- Indicates the privacy protocol that this entry should belong to. Possible privacy
protocols are:
•
None:
No privacy protocol
.
•
An optional flag to indicate that this user uses DES authentication protocol
.
•
An optional flag to indicate that this user uses AES authentication protocol.
