Introduction

The following information provides examples of logging in to the device through Telnet.

Prerequisites

The configuration examples were created and verified in a lab environment, and all the devices were started with the factory default configuration. When you are working on a live network, make sure you understand the potential impact of every command on your network.

The following information is provided based on the assumption that you have basic knowledge of device login.

Software versions used

These configuration examples were created and verified on R6749P14 of the H3C MSR3610-X1 router. The configuration examples apply to the H3C Comware 7 MSR router series. Operations might vary slightly by product model and software version.

Example: Logging in to a device through Telnet (CLI)

Network configuration

As shown in Figure 1, use a host with IP address 192.168.0.2/24 to log in to the device through Telnet.

Figure 1 Network diagram

 

Restrictions and guidelines

·     Make sure the host and the device can communicate with each other. Enable Telnet service port number 23.

·     Enable the Telnet client feature on the host.

·     By default, the Telnet server is disabled on the device. You must log in to the device through the console port and enable the Telnet server.
