xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual
1
INTRODUCTION
The Switch can be managed through the Switch’s serial port, Telnet, or the Web-based management agent. The Command Line
Interface (CLI) can be used to configure and manage the Switch via the serial port or Telnet interfaces.
This manual provides a reference for all of the commands contained in the CLI. Configuration and management of the Switch via the
Web-based management agent is discussed in the Manual.
Accessing the Switch via the Serial Port
The Switch’s serial port’s default settings are as follows:
•115200 baud
•no parity
•8 data bits
•1 stop bit
A computer running a terminal emulation program capable of emulating a VT-100 terminal and a serial port configured as above is
then connected to the Switch’s serial port via an RS-232 DB-9 cable.
With the serial port properly connected to a management computer, the following screen should be visible. If this screen does not
appear, try pressing Ctrl+r o refresh the console screen.
Figure 1-1. Initial CLI screen
There is no initial username or password. Just press the Enter key twice to display the CLI input cursor −DGS-3627:5#.This is the
command line where all commands are input.
Setting the Switch’s IP Address
Each Switch must be assigned its own IP Address, which is used for communication with an SNMP network manager or other
TCP/IP application (for example BOOTP, TFTP). The Switch’s default IP address is 10.90.90.90. You can change the default Switch
IP address to meet the specification of your networking address scheme.
The Switch is also assigned a unique MAC address by the factory. This MAC address cannot be changed, and can be found on the
initial boot console screen – shown below.
1

xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual
Figure 1-2. Boot screen
The Switch’s MAC address can also be found in the Web management program on the Switch Information (Basic Settings) window
on the Configuration menu.
The IP address for the Switch must be set before it can be managed with the Web-based manager. The Switch IP address can be
automatically set using BOOTP or DHCP protocols, in which case the actual address assigned to the Switch must be known.
The IP address may be set using the Command Line Interface (CLI) over the console serial port as follows:
1. Starting at the command line prompt, enter the commands config ipif System ipaddress xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy.
Where the x’s represent the IP address to be assigned to the IP interface named System and the y’s represent the
corresponding subnet mask.
2. Alternatively, you can enter config ipif System ipaddress xxx.xxx.xxx.xxx/z. Where the x’s represent the IP address to be
assigned to the IP interface named System and the zrepresents the corresponding number of subnets in CIDR notation.
The IP interface named System on the Switch can be assigned an IP address and subnet mask which can then be used to connect a
management station to the Switch’s Telnet or Web-based management agent.
Figure 1-3. Assigning an IP Address
In the above example, the Switch was assigned an IP address of 10.24.22.200 with a subnet mask of 255.0.0.0. The system message
Success indicates that the command was executed successfully. The Switch can now be configured and managed via Telnet, SNMP
MIB browser and the CLI or via the Web-based management agent using the above IP address to connect to the Switch.

USING THE CONSOLE CLI
The Switch supports a console management interface that allows the user to connect to the Switch’s management agent via a serial
port and a terminal or a computer running a terminal emulation program. The console can also be used over the network using the
TCP/IP Telnet protocol. The console program can be used to configure the Switch to use SNMP-based network management software
over the network.
This chapter describes how to use the console interface to access the Switch, change its settings, and monitor its operation.
Note: Switch configuration settings are saved to non-volatile RAM using the save command. The current
configuration will then be retained in the Switch’s NV-RAM, and reloaded when the Switch is rebooted. If
the Switch is rebooted without using the save command, the last configuration saved to NV-RAM will be
loaded.
Connecting to the Switch
The console interface is used by connecting the Switch to a VT100-compatible terminal or a computer running an ordinary terminal
emulator program (e.g., the HyperTerminal program included with the Windows operating system) using an RS-232C serial cable.
Your terminal parameters will need to be set to:
•VT-100 compatible
•115200 baud
•8 data bits
•No parity
•One stop bit
•No flow control
Users can also access the same functions over a Telnet interface. Once an IP address has been set for the Switch, users can use a
Telnet program (in VT-100 compatible terminal mode) to access and control the Switch. All of the screens are identical, whether
accessed from the console port or from a Telnet interface.
After the Switch reboots and you have logged in, the console looks like this:
Figure 2- 1. Initial Console Screen after logging in
Commands are entered at the command prompt, DGS-3627:5#.

xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual
There are a number of helpful features included in the CLI. Entering the ?command will display a list of all of the top-level
commands.
Figure 2- 2. The ? Command
When users enter a command without its required parameters, the CLI will prompt a Next possible completions: message.
Figure 2- 3. Example Command Parameter Help
In this case, the command config account was entered with the parameter <username>. The CLI will then prompt to enter the
<username> with the message, Next possible completions:. Every command in the CLI has this feature, and complex commands
have several layers of parameter prompting.
In addition, after typing any given command plus one space, all of the next possible sub-commands can be seen, in sequential order,
by repeatedly pressing the Tab key.
To re-enter the previous command at the command prompt, press the up arrow cursor key. The previous command will appear at the
command prompt.
4

xStack DGS-3600 Series Layer 3 Gigabit Ethernet Managed Switch CLI Manual
Figure 2- 4. Using the Up Arrow to Re-enter a Command
In the above example, the command config account was entered without the required parameter <username>, the CLI returned the
Next possible completions: <username> prompt. The up arrow cursor control key was pressed to re-enter the previous command
(config account) at the command prompt. Now the appropriate username can be entered and the config account command re-
executed.
All commands in the CLI function in this way. In addition, the syntax of the help prompts are the same as presented in this manual −
angle brackets < > indicate a numerical value or character string, braces { } indicate optional parameters or a choice of parameters,
and brackets [ ] indicate required parameters.
If a command is entered that is unrecognized by the CLI, the top-level commands will be displayed under the Available commands:
prompt.
Figure 2- 5. Available Commands
The top-level commands consist of commands such as show or config. Most of these commands require one or more parameters to
narrow the top-level command. This is equivalent to show what? or config what? Where the what? is the next parameter.
For example, if you enter the create command with no additional parameters, the CLI will then display all of the possible next
parameters.

COMMAND SYNTAX
The following symbols are used to describe how command entries are made and values and arguments are specified in this manual.
The online help contained in the CLI and available through the console interface uses the same syntax.
Note: All commands are case-sensitive. Be sure to disable Caps Lock or
any other unwanted function that changes text case.
<angle brackets>
Purpose Encloses a variable or value that must be specified.
Syntax create ipif <ipif_name 12> <network_address> (<ip_addr/netmask>)
<vlan_name 32> {secondary | state [enable | disable]}
Description In the above syntax example, users must supply an IP interface name in the
<ipif_name> space, a VLAN name in the <vlan_name 32> space, and the
network address, including the netmask, in the <network_address>
(<ip_addr/netmask>) space. Do not type the angle brackets.
Example
Command create ipif Engineering 10.24.22.5/255.0.0.0 Design
[square brackets]
Purpose Encloses a required value or set of required arguments. One value or argument
can be specified.
Syntax create account [admin | operator | user] <username 15>
In the above syntax example, users must specify the admin, operator, or user
level account to be created. Do not type the square brackets.
Description
Example
Command create account admin ctsnow
