SNMP version 3 helps you to manage your network using SNMP protocol to facilitate the exchange of management information between network devices.
Using the Manager, you can add SNMPv3 users at the domain level and allow devices to make use of this configuration or add users at the device level.
SNMPv3 users created at a domain level are available to the devices and the child domains. Thus, changes done at the domain level are also reflected in the devices using this configuration and the child domains.
Child domains are restricted to only view and use the SNMPv3 users created at the parent domain level.
SNMPv3 in HA pair devices
If both the devices have SNMPv3 configured, before becoming the part of the HA pair, the failover (Stand by) device configuration is deleted and updated with the Primary device configuration. Any configuration changes done after HA pair creation is updated onto both the devices.

The SNMPv3 Users action enables you to do the following:
Adding SNMPv3 users at domain level: Add a NMS user with the authentication and private key.
Editing SNMPv3 users at domain level: Edit the authentication and private key.
Deleting SNMPv3 users from the domain: Delete user from NMS database.
Note
SNMPv3 users created in the NMS Users page under Global tab can be added to the SNMPv3 users created at the device level using the Assign Domain User button and then assigning the user.
