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 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 preconfigured user
credentials using SSH:
ssh username@hostname <CLI Command>
or
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>
or
cat < CLIscript.file > | ssh admin@hostname
The script is run and the actions contained in the script are performed.
