This tutorial will walk you through step by step on how to enable secure SNMPv3 on a Dell X1052 switch, although this will work on any of the X series switches. We'll show you exactly what to enable in the web interface as well as the equivalent command line terminal commands.

CLI Commands:

Enter these four lines:

• snmp-server engineID local 800002a203e4f00483ae0e
• snmp-server contact "Server Rack"
• snmp-server group ITswapshop v3 priv read Default
• snmp-server user ITswapshopUser ITswapshop v3 auth sha ITswapshop.com!!! priv ITswapshop.com123!

GUI Web Interface:

To begin, go to Network Administration > SNMP Monitoring. On the right, click Edit next to Global Parameters. Click the Gear icon on the right of the Edit Global Parameters window. Set the Local Engine ID Type to Default and set SNMP Notifcations, Traps, & Authentication Notifications to Enabled and then click OK. If you click back on the Gear icon, you'll notice the Local Engine ID field is now configured with the default Engine ID and the Local Engine ID Type is set to User-Defined:

On the SNMP Monitoring page, click the Edit button to the right of Access Control. Click Add on the Edit Access Control window. On the Add Access Control window, set the following options:

On the SNMP Monitoring page, click the Edit button to the right of User Security Model. Click Add on the Edit User Security Model window. Enter the following information:

That's it! You now have a secure SNMPv3 setup. If you would like to test it, you can verify everything is working properly the free Paessler SNMP Tester tool. Match the settings as seen below and set it to check the Uptime. If successful, you'll see the uptime returned to you in the results:
