If you discover a device utilizing unauthorized access through your wireless network, you can block the MAC address to prevent future access. The following procedure uses an access control list on a wireless access point to block a specific MAC address.

Back up the running configuration

  1. Click My Dashboards >  Network Configuration > Configuration Management.
  2. Select one or more nodes.
  3. Click Download > Running.

Block a MAC address on a wireless access point

  1. Click My Dashboards >  Network Configuration > Jobs.
  2. Click Create New Job.
  3. Name the job, and select Execute Command Script on Devices from Job Type.
  4. Select the Schedule Type. If you are creating an Advanced schedule, use the five fields to create an appropriate cron expression.
  5. Add a comment if this job relates to a business rule, and click Next.
  6. Select the nodes to target with this job, and click Next.
  7. Select an email notification option, and click Next. If you click Email Results, the default Email Notification Settings and SMTP Server Settings Email Notification Settings and SMTP Server Settings are populated. These settings can be overridden in each job.
  8. Add the script to execute.
    • If you want to load a saved script, click Load Saved Script, and select a script.
    • If you want to load an existing script from disk, click Load Script from File, browse to the file, and click Open.
    • If you want to create a new script, enter your script in the text box. For example:

      ${EnterConfigMode}
      access-list 724 deny 000e.0ca1.a2b4 0000.0000.0000
      exit
      wr mem

      Where 724 is the name of the ACL, and 000E.0CA1.A2B4 is the MAC address to block. ${EnterConfigMode} is a variable that is equivalent to config terminal on Cisco devices.

  9. If you want to save a script, click Save Script, specify a location, and click Save.
  10. Select Filter Results that match a pattern if you want to see in the script output only those lines that match a specific regular expression pattern.
  11. Select Show Commands in Output to view what SolarWinds NCM sent to the targeted devices.
  12. Click Next.
  13. Review the settings for the job, and click Finish.
