The pin assignments between the console and a DTE terminal server are as follows:

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>

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:
