Which command is used to enable SSH on a Cisco device?

The command "ip ssh version 2" is used to enable SSH on a Cisco device and configure it to use SSH version 2, which is more secure than version 1. By specifying the version, you are ensuring that all SSH connections will comply with the security protocols of SSH version 2, which includes stronger encryption algorithms and improved security features.

This command is typically configured in global configuration mode, and it is essential for securing remote access to network devices. Enabling SSH allows for encrypted communications, making it much more secure than using protocols like Telnet, which sends data in plaintext.

Configuring SSH properly is integral for network administrators, as it helps protect sensitive information and provides a more secure method of managing network devices remotely.
