  1. Go to Configure > Switch settings 
  2. Enable the Access management option.

The default setting is "Deny all." If you want to allow specific IP addresses to access the Nebula switch via Telnet, please click "+Add allow IP range" and enter the information.

Note: This not only restricts Telnet access to your Nebula switch but also limits other local access methods to the switches, including SSH, HTTP, HTTPS, and FTP.
