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 les. This method of

connectivity is supported with S4810, S4048–ON, S3048–ON, S4820T, and Z9000 switches 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 precongured 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.

Executing Local CLI Scripts Using an SSH Connection

You can execute CLI commands by entering a CLI script in one of the following ways:

ssh username@hostname <CLIscript.file>

cat < CLIscript.file > | ssh admin@hostname

The script is run and the actions contained in the script are performed.
