Configuring SNMPv3 Users

The SNMPv3 Users table lets you configure up to 10 SNMPv3 users for authentication and privacy.

● If you delete a user that is associated with a trap destination (see Configuring SNMP Trap Destinations with IP Addresses), the trap destination becomes disabled and the trap user reverts to default (i.e., SNMPv2).
● If you configure an SNMPv3 user(s), the device ignores all SNMP requests (Get and Set operations) from SNMPv2 users (sends the authenticationFailure trap).
● If you want to use the same SNMPv3 Users table configuration for another device, before uploading this device's configuration file (.ini) to the other device, you must edit the file so that the passwords ('Authentication Key' and 'Privacy Key' parameters) are in plain text.

The following procedure describes how to configure SNMPv3 users through the Web interface. You can also configure it through ini file [SNMPUsers] or CLI (configure system > snmp settings > v3-users).

➢ To configure an SNMPv3 user:
1. Open the SNMPv3 Users table (Setup menu > Administration tab > SNMP folder > SNMP V3 Users).
2. Click New; the following dialog box appears:

3. Configure the SNMPV3 user according to the table below.
4. Click Apply.

[SNMPUsers_AccessGroup]

Assigns an Access Group (configured in the SNMP Access Groups table - see Configuring SNMP Access Groups) to the SNMPv3 user.

By default, no value is defined.

Note: This parameter is applicable only when in advanced SNMP mode (see Enabling the SNMP View-based Access Control Model).
