INTRODUCTION
The Switch can bemanagedthroughthe switch’sserial port, Telnet, orthe Web-basedmanagementagent. The Command Line
Interface (CLI)can be usedtoconfigure andmanage the switch via the serial port orTelnet interfaces.
This manual provides a reference forall ofthe commands containedin the CLI. Configuration and management ofthe switch via
the Web-based management agent is discussedin the User’s Guide.
Accessing the Switch viathe Serial Port
The switch’s serial port’s default settings are as follows:
• 9600 baud
• noparity
• 8data bits
• 1stop bit
A computer runninga terminal emulation programcapable of emulatingaVT-100 terminal andaserial portconfigured as above
is thenconnectedtothe switch’s serial port via an RS-232 DB-9 cable.
Withthe serial port properlyconnectedtoa management computer, thefollowingscreenshould be visible. If this screen does not
appear, trypressing Ctrl+r torefreshthe console screen.
Figure 1-1. Initial CLI screen
There is no initial username orpassword.Just press the Enter keytwice todisplaythe CLI input cursor −local>.This is the
command line where all commands are input.
Setting the Switch s IP Address

DES-3350SR Layer3 Gigabit Switch
2
Each Switch must beassigned its ownIPAddress, which is used forcommunication with an SNMP networkmanager orother
TCP/IPapplication(for exampleBOOTP, TFTP).The switch’sdefault IPaddress is 10.90.90.90.Youcan change thedefault
Switch IP address tomeet the specification of yournetworking address scheme.
The switch is alsoassigned auniqueMAC address bythe factory.This MAC address cannotbe changed, andcanbe found on
the initial boot console screen –shown below.
Figure 1-2. Boot Screen
The switch’sMAC address can alsobe foundinthe Web management programonthe SwitchInformation(Basic Settings)
windowon the Configurationmenu.
The IPaddress forthe switch must beset before it can bemanagedwith the Web-based manager. Theswitch IP address can be
automaticallyset using BOOTP or DHCP protocols, in which case the actual address assignedtothe switch must be known.
The IP address maybe set using the CommandLine Interface (CLI)over the console serial port as follows:
1. Startingat thecommandlineprompt, enterthecommands configipifSystemipaddress
xxx.xxx.xxx.xxx/yyy.yyy.yyy.yyy.Where the x’srepresent the IP address tobe assignedtotheIPinterface named
System andthe y’s represent the corresponding subnet mask.
2. Alternatively,you can enter configipif Systemipaddress xxx.xxx.xxx.xxx/z.Where the x’srepresent the IPaddress to
be assigned tothe IPinterface named System and the zrepresents the corresponding number of subnets in CIDR
notation.
The IP interface named System on the switch canbe assigned an IP address andsubnet mask which can then be usedtoconnect a
management station tothe switch’s Telnet or Web-based management agent.

Figure 1-3. Assigning an IP Address
Inthe aboveexample, theswitch was assigned anIPaddress of 10.53.13.144/8withasubnet maskof 255.0.0.0. The system
message Success indicates that the command was executedsuccessfully.Theswitch can nowbe configuredandmanagedvia
Telnet andthe CLI or via the Web-basedmanagement agent using the above IP address to connect to the switch.

USING THE CONSOLE CLI
The DES-3350SR supports aconsole managementinterface that allowstheuser to connect to theswitch’smanagementagent via
aserial port and aterminal oracomputer runningaterminal emulationprogram.Theconsole can alsobeused over thenetwork
usingtheTCP/IPTelnet protocol. The console programcan be used toconfigurethe switchtouse anSNMP-basednetwork
management software over the network.
This chapter describes howto use the console interface to access the switch, change its settings, andmonitor its operation.
Note:Switch configuration settings aresaved to non-volatile RAM using
the save command. The current configuration willthen be retained in the
switch sNV-RAM, and reloaded when the switch is rebooted. Ifthe switch
isrebooted without using the savecommand, the lastconfiguration saved
to NV-RAM will be loaded.
Connecting to the Switch
The console interface is usedbyconnectingtheSwitch to aVT100-compatible terminal oracomputerrunninganordinary
terminal emulator program(e.g., the HyperTerminal program includedwith the Windowsoperating system)usinganRS-232C
serial cable. Yourterminal parameters will need to be set to:
• VT-100 compatible
• 9600baud
• 8 databits
• Noparity
• One stop bit
• Noflowcontrol
You can alsoaccess the samefunctions over a Telnet interface. Once you have set an IPaddress foryour Switch, you canuse a
Telnet program(in VT-100 compatible terminal mode) to access and control the Switch.All ofthe screensare identical, whether
accessed from the console port or from a Telnet interface.
After the switchreboots andyou have logged in, the console looks like this:

Commands are enteredat the command prompt, local> Thereare a numberofhelpful features included in the CLI.Enteringthe ?
command will displaya list of all ofthe top-level commands.
Figure 2-2. The ? Command
When youenter acommandwithout its required parameters, the CLIwill prompt youwith a Next possible completions:
message.

Figure 2-3. Example Command Parameter Help
Inthis case, the command config account was enteredwith the parameter <username>.TheCLI will thenprompt youto enter
the <username> withthemessage, Next possible completions:.Everycommand inthe CLIhas this feature, andcomplex
commands have several layers ofparameterprompting.
Inaddition, after typinganygivencommandplus one space, you can see all of thenext possible sub-commands, insequential
order, byrepeatedlypressing the Tab key.
To re-enter thepreviouscommand at thecommand prompt, press the up arrowcursor key.Theprevious commandwill appear at
the command prompt.
Figure 2-4. Using the Up Arrowto Re-enter a Command
Intheaboveexample, the command config account was enteredwithoutthe requiredparameter <username>,the CLIreturned
the Next possible completions:<username> prompt. The up arrowcursor control keywas pressedtore-enter the previous
command (config account)at thecommand prompt. Nowtheappropriate User name can beenteredandthe configaccount
command re-executed.

All commands in theCLIfunction inthis way.In addition, the syntax of the helpprompts are the same as presented inthis
manual −angle brackets <>indicate a numerical value orcharacter string, braces {}indicate optional parameters or achoice of
parameters, and brackets [ ] indicate required parameters.
Ifacommand is entered that is unrecognized bytheCLI, the top-level commands will be displayed under the Available
commands: prompt.
Figure 2-5. The Next Available Commands Prompt
The top-level commandsconsist ofcommandssuch as show or config.Most ofthese commands requireoneor moreparameters
to narrowthe top-level command. This is equivalent to show what? or config what? Where the what?is the next parameter.
Forexample, if you enterthe show command with noadditional parameters, the CLIwill then displayall of thepossible next
parameters.

Inthe above example, all ofthe possible next parameters for the show commandare displayed. At the nextcommandprompt, the
up arrowwas usedtore-enter the show command, followedbythe account parameter.The CLI thendisplaysthe user accounts

COMMAND SYNTAX
The followingsymbols are used to describe howcommandentries are madeandvalues andarguments are specified in this
manual. The online help contained inthe CLI andavailable through the console interface uses the same syntax.
Note:All commands are case-sensitive. Be sure to disable CapsLock or
anyother unwanted function that changes text case.

there are three possible outcomesof performing a systemreset.
See the following chapter, Basic Commandsfor more details
about the reset command.
