SNMPv3 Community String Access Control

You can control the access to the SNMPv3 community string information on models. You can decide whether you want to display or hide the SNMP v3 community string to specific users. This functionality, therefore, gives you the ability to restrict the display of this information, making it available only to those users who are supposed to view the information.
By default, the 
SNMPv3 Community String v3
 option is enabled. However, if any customization has been done on the options under the 
Privileges
 section on the lower version of
DX NetOps Spectrum
for the administrator and operator roles, then after upgrade to 10.4.1, the 
SNMPv3 Community String v3
 option is displayed as not selected. Furthermore, if no customization has been done, the
SNMPv3 Community String v3
option is displayed as enabled.
Follow these steps:
  1. Access the OneClick interface.
  2. Click the 
    Users
     tab in the 
    Navigation
     pane.
  3. Locate and select the required user.
  4. Click the 
    Access
     tab in the 
    Contents
     pane.
  5. Click 
    Add/Remove
     on the 
    Privileges
     tab.
  6. Expand 
    Model Management, View Attributes
     to view the options.

Consideration
If the 
SNMP Community String v3
 option is disabled (not selected) at the time of upgrading to 10.4.1, then after the upgrade, both 
SNMP Community String v3
 and 
SNMP Community String
 will be disabled. 
The following screenshot shows the required information. Note that both 
SNMP Community String v3
 and 
SNMP Community String 
are not selected:
