3 Logging In Through Telnet

Introduction

The device supports Telnet. You can manage and maintain the switching engine remotely by Telnetting to the switching engine.

To log in to the switching engine through Telnet, the corresponding configuration is required on both the switching engine and the Telnet terminal.

You can also log in to the switching engine through SSH. SSH is a secure shell added to Telnet. Refer to the SSH Operation for related information.
