Introduction to CLI
This chapter introduces line commands and gives a summary of commands available.
25.1 Command Line Interface Overview
In addition to the web configurator, you can use line commands to configure the switch. It is recommended that
you use the web configurator for everyday management of the switch and that you use line commands for
advanced switch diagnosis and troubleshooting. If you have problems with your switch, customer support may
request that you issue some of these commands to assist them in troubleshooting.
You can use the “config save” command to save 802.1Q, STP, Cluster and IP configuration
changes to non-volatile memory (Flash). These changes are effective after you restart the
switch.
However you cannot use “config save” for all other line command configurations. These are
saved in volatile memory (DRAM), so are not effective after you restart the switch.
25.1.1 Accessing the Command Line Interface
There are two ways to access the command line interface on the ES-2024:
• Telnet to the switch
• Connect a computer to the console port and use terminal emulation software configured to the following
parameters:
VT100 terminal emulation 9600 bps
No parity, 8 data bits, 1 stop bit No flow control
25.1.2 Command Conventions
The system uses a one-level command structure. You must type the full command every time, as follows.
