Logging in through SSH

SSH offers a secure method to remote login. By providing encryption and strong authentication, it

protects devices against attacks such as IP spoofing and plain text password interception. For more

information, see Security Configuration Guide.

You can use an SSH client to log in to the device for remote management, or use the device as an SSH

client to log in to an SSH server.

By default, SSH login is disabled on the device. To log in to the device through SSH, you must log in to

the device through any other method and configure SSH login on the device first.
