5.3.20 SNMP Users
Configure SNMPv3 user table on this page. The entry index keys are
Engine ID
and
User Name
.
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
: 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.
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 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:
