Accessing the CLI Interface and

Running Scripts Using SSH

In addition to the capability to access a device using a console connection or a Telnet session, you can also

use SSH for secure, protected communication with the device. You can open an SSH session and run

commands or script files. This method of connectivity is supported and provides a reliable, safe

communication mechanism.

Entering CLI commands Using an SSH

Connection

You can run CLI commands by entering any one of the following syntax to connect to a switch using the

preconfigured user credentials using SSH:

ssh username@hostname <CLI Command>

echo <CLI Command> | ssh admin@hostname

The SSH server transmits the terminal commands to the CLI shell and the results are displayed on the screen

non-interactively.
