KVM over IP User Manual
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 31, 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.
Authentication Protocol:
Indicates the authentication protocol that this entry should belong to. Possible
authentication protocols are:
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 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 39. For SHA
authentication protocol, the allowed string length is 8 to 39. The allowed
content is ASCII characters from 33 to 126.
