Issue/Introduction

Missing SNMPv3 trap settings send <Missing> for msgAuthenticationParameters and msgPrivacyParameters.

Resolution

From CAS 3.1.6.x and above, you can set these configurations via the command-line interface (CLI). If you have already configured SNMP v3 and SNMP alerts, follow these steps in CLI configuration mode:

1. Set the SNMP target with the following command:

   snmp target cas-target-v3-<ip> usm sec-level auth-priv

2. Configure the VACM group by entering the command:

   snmp vacm group cas-group-v3 access usm auth-priv notify-view cas-view

This will enable privacy level security for SNMP traps.

Important Notes:

1. Be cautious when making further modifications to SNMP settings via the UI, as this may override the changes made through the CLI.
2. If you wish to tidy up your configuration, you can remove the VACM group access with the following command:

   no snmp vacm group cas-group-v3 access usm no-auth-no-priv notify-view cas-view
