Configuring Telnet Access on Cisco Router

When configuring Telnet access on a Cisco router, it’s crucial to enhance security through proper password and login settings. Follow these steps for a robust setup:

Access Line Configuration:
Enter the Virtual Terminal Line configuration mode, specifying the range of simultaneous connections allowed (0 to 4 in this example for Telnet access).

Router(config)#line vty 0 4

Setting Telnet Password:
Assign a password for Telnet access.

Router(config-line)#password passwd

Note: Replace “passwd” with your chosen password.

Enabling Login Prompt:
Enable login prompting for Telnet access.

Router(config-line)#login

Setting Privilege Mode Password:
To prompt for a password when entering Privilege EXEC mode, configure the enable password.

Router(config-line)#exec-timeout 4 0

Note: This configuration disconnects the session if there’s no activity within the specified time (4 minutes in this example). Adjust as needed.

Enable Password Configuration:
To activate Telnet, ensure the enable password is set.

Router(config)#enable password hossein

Note: Substitute “hossein” with your desired enable password.

By implementing these configurations, Telnet access to your Cisco router is fortified with password protection, login prompts, and an automatic session timeout. This contributes to a more secure network environment.
