Figure 11: The Enable SNMPv3 option has been selected and the New SNMPv3 Credential section is complete.
The New User Name field can be any name you choose.
The New Authentication Passphrase field can be any word or phrase that is at least 9 alphanumeric characters.
The New Privacy Passphrase field can be any word or phrase that is at least 9 alphanumeric characters.
CAUTION:
These instructions are for the initial configuration of SNMPv3. Once you finish this configuration, your devices will require these
credentials whenever anyone attempts to access settings over the network. Be sure to remember these credentials and provide
them only to authorized users. If these credentials are forgotten, the only way to restore communication between HP Web
Jetadmin and the print devices is to restore them to factory default settings.
Web Jetadmin retains the SNMPv3 credentials for each device, and it will not prompt for them as long as the settings remain the
same. You can clear the Web Jetadmin Device Cache to cause Web Jetadmin to require the credentials again. Web Jetadmin stores
the SNMPv3 credentials in an encrypted form.
Scroll down to the SNMPv1 Settings section, and select SNMPv1 disabled (Figure 12).
Figure 12: The SNMP Version 3 Only setting.
This setting limits all SNMP configuration communication to only SNMPv 3. Once applied your devices will not allow SNMPv1
SET and SNMPv2 GET.
Choose Apply at the bottom of the SNMP Version Access Control configuration to apply the settings to the selected devices. If
your configuration is not successful, you can click the Details button for more information on why the configuration failed.
