Console and vty Settings

Console and vty Settings

Console and vty (Virtual Teletype) settings are used to manage the remote access to network devices. Console ports are used for the local management of network devices, while vty lines are used for remote management.

The console port is typically used for initial configuration and troubleshooting of the device, and it is usually accessed via a console cable that connects the device to a computer or terminal. The vty lines are used for remote access to the device via Telnet or SSH.

To configure console and vty settings, you can use the following commands in Cisco IOS:

line con 0: This command is used to configure console settings. You can use it to set the console speed, enable password protection, configure logging, and more.

line vty 0 15: This command is used to configure vty settings. You can use it to set the vty password, enable Telnet or SSH access, configure timeouts, and more.

By default, Cisco devices have five vty lines, numbered 0 to 4. You can configure each vty line separately or use the all keyword to apply the configuration to all vty lines.

For example, to configure the console speed to 9600 baud and set a vty password, you could use the following commands:

line con 0

  speed 9600

  login

line vty 0 4

  password mypassword

  login

These commands set the console speed to 9600 baud and require a login to access the console port. They also set a password for vty access and require a login for all vty lines.
