You can configure SNMPv3 in the Unified Access Gateway Admin UI. SNMPv3 has enhanced security features such as authentication and privacy. Unified Access Gateway continues to support SNMPv1 and SNMPv2c, which are the default versions. You can also configure SNMPv3 through PowerShell deployment by adding certain SNMPv3-related settings in the INI file.

If you have deployed Unified Access Gateway through PowerShell, enabled SNMP, but not configured SNMPv3 settings, then by default SNMPv1 and SNMPV2c versions are used.

You can also configure SNMPv3 settings using PowerShell. For more information about these parameters, see Using PowerShell to Deploy the Unified Access Gateway Appliance.
