The SNMP v3 protocol allows for encrypted communication. To take advantage of this, users need to have an Authentication Pass Phrase and Privacy Pass Phrase, which act as shared secrets between them and the PXE.
To configure users for SNMP v3 encrypted communication:
Choose User Management > Users. The Manage Users dialog appears.
Select the user by clicking it.
Click Edit or double-click the user. The Edit User 'XXX' dialog appears, where XXX is the user name.
To change the SNMPv3 access permissions, click the SNMPv3 tab and make necessary changes. For details, see Step 6 of Creating a User Profile.
Click OK. The user is now set up for encrypted SNMP v3 communication.
