1. About D-LINK OS Software
About D-LINK OS Software
The two primary purposes of the D-Link OS are as follows:
•To support the attached hardware in switching frames according to the Layer 2, 3, or 4
information contained in the frames.
•To provide network administrators with a complete device management portfolio.
Product Concept
The evolution of fast Ethernet and Gigabit Ethernet switching from high-end backbone applications to
desktop switching applications is ongoing. At the same time, the cost of this technology continues to fall,
even as its performance and feature sets continue to be enhanced. Relatedly, there is an increasing
demand for devices that can switch Layers 2, 3, and 4, and D-LINK OS software offers a highly adaptable
solution for these constantly increasing demands.
For each networking device on which the D-LINK OS software base runs, the exact functionality provided
by the device will vary according to the platform used and the requirements of the D-LINK OS software.
The D-LINK OS software comes equipped with a comprehensive set of management functions that can
be used to manage both the D-LINK OS software itself and the network. More specifically, the D-LINK OS
software can be managed via either of the following methods:
•Command-Line Interface (CLI)
•Simple Network Management Protocol (SNMP)
Both of these D-LINK OS management options allow the user to control, configure, and otherwise
manage the software locally or using in-band or out-of-band mechanisms. The management is standards-
based, with a private MIB and specific configuration parameters allowing for control of functions not
completely specified in the MlBs.

2. Using the Command-Line
The command-line interface (CLI) constitutes a text-based means by which to monitor and manage the
system. The CLI can be accessed by the use of a direct serial connection or through the used of a remote
logical connection via telnet or SSH.
Command Syntax
A command consists of one or more words. A given command may or may not be followed by one or
more parameters, as parameters may be required or optional depending on the command being used.
For example, the commands network and clear vlan do not require parameters, whereas other
commands, such as network parms, require that a value is included after the command. Such
parameter values must be typed in a specific order, with any optional parameters following any required
parameters. The following example illustrates the command syntax for the network parms command:
network parms ipaddr netmask [gateway]
•The term network parms is the name of the command itself.
•The terms ipaddr and netmask are parameters and are examples of required values that must
be entered after the command itself are entered.
•The term [gateway] is an optional parameter, meaning that it is not required that a value be
entered in place of the parameter.
Each command is listed by the command name in the CLI Command Reference, which also provides a
brief description of each command.
The command keywords and the associated required and optional parameters are shown under Format.
The command mode used must be in to access the command is indicated under Mode.
The default value for a configurable setting on the device, if any, is indicated by Default.
Furthermore, the information that a given command shows is described by the show command.
Command Conventions
For a given command, the parameters used may include mandatory values, optional values, or keyword
choices. Such parameters follow a prescribed order. Table 1explains the conventions used in this guide
to distinguish between value types.
Table 1: Parameter Conventions
Symbol Example Description
[] Brackets
[value]
Denotes an optional parameter.
Italic font in a parameter value or [value] Denotes a variable value. You must
substitute the italicized text and brackets
with an appropriate value, such as a name
or number.
{} Braces
{choice1 | choice2}
Indicates a parameter selection option.
| Vertical bars
choice1 | choice2
Separates mutually exclusive choices.
[{}] Braces within brackets
[{choicel | choice2}]
Denotes a choice within an optional

Symbol Example Description
element.
Common Parameter Values
The values for parameters might be names (strings) or numbers. Enclose the name value in double
quotes in order to use spaces as part of a name parameter. For example, using the expression “System
Name with Spaces” requires the system to accept the spaces, while the use of empty strings (“”) is not
valid for user-defined strings. Table 2 explains common parameter values and value formatting.
Table 2: Parameter Descriptions
Parameter Description
ipaddr This parameter constitutes a valid lP address. The IP address can be entered
in the following formats:
a (32 bits)
a.b (8.24 bits)
a.b.c (8.8.16 bits)
a.b.c.d (8.8.8.8)
Besides these formats, the CLI also accepts decimal, hexadecimal, and octal
formats in the following input formats (where nconsists of any valid
hexadecimal, octal, or decimal number):
0xn (CLI assumes hexadecimal format.)
0x (CLI assumes octal format with leading zeros.)
n (CLI assumes decimal format.)
Interface or
slot/port
Used to indicate a valid slot and port number separated by a forward slash.
For example, 0/1 denotes slot number 0 and port number 1.
Logical Interface Indicates a logical slot and port number. This applies in the case of a port-
channel (LAG). The logical slot/port can be used to configure the port-channel.
Character strings Double quotation marks are used to identify character strings, e.g., “System
Name with Spaces”. An empty string (“”) will not be considered valid.
Slot/Port Naming Convention
In referencing physical entities such as cards and ports, the D-LINK OS software uses a slot/port naming
convention. This convention is also used by the software to identify certain logical entities, such as Port-
Channel interfaces.
There are two uses for the slot number. With respect to physical ports, it indicates the card containing the
ports. With respect to logical and CPU ports, it also indicates the type of interface or port.
Table 3: Types of Slot Numbers
Slot Type Description
Physical slot numbers Physical slot numbers start with zero, and are assinged up to the maximum
number of physical slots.

5000 Series Layer 2/3 Managed Data Center Switch CLI Reference Guide
10
Slot Type Description
Logical slot numbers Logical slots numbers are given immediately after physical slot numbers and
identify port-channel (LAG) or router interfaces. The values for logical slot
numbers are dependent upon the type of logical interface and can differ from
platform to platform.
CPU slot numbers The CPU slot numbers are given immediately after the logical slot numbers.
For a given slot, the port refers to the specific physical port or logical interface being managed on the slot.
Table 4: Types of Ports
Port Type Description
Physical Ports Starting from zero, the physical ports for each slot are numbered in sequence.
Logical Interfaces Port-channel or Link Aggregation Group (LAG) interfaces consist of logical
interfaces that are used for bridging functions only.
VLAN routing interfaces consist of logical interfaces that are used for routing
functions only.
Loopback interfaces consist of logical interfaces that are constantly up.
Tunnel interfaces consist of logical point-to-point links in which encapsulated
packets are carried.
CPU ports CPU ports consist of ports that are handled by the driver and are physical
entities that are located in physical slots.
Note: In the CLI itself, the slot/port format is not used for loopback interfaces. Use the loopback ID
instead to specify a loopback interface.
Using the No Form of a Command
The no keyword is used to form the negative form of an existing command and is not a new or distinct
command itself. A no form exists for almost every configuration command. in general, the no form of a
command is used to reverse the action of the command or to reset a given value back to its default. For
example, the no shutdown configuration command is used to reverse the shutdown of an interface.
Alternatively, a given command can be used without the no keyword to reenable a previously disabled
feature or to enable a feature that is disabled by default. The no form is only available for the
configuration commands.

Executing Show Commands
Any mode (Global Config, VLAN Config, etc.) can be used to issue all show commands. These
commands are used to obtain information about the system and its feature-specific configuration, status,
and statistics.
CLI Output Filtering
In many cases, CLI show commands will cause a considerable amount of content to be displayed to the
user. Such large amounts of content can be confusing and cumbersome to parse through to locate the
desired information. However, by using the CLI Output Filtering feature, the user can, when executing CLI
show display commands, optionally specify arguments in order to filter the CLI output so that only the
desired information is displayed. The displayed information will thus be simplified, making it easier for the
user to find the desired information.
The primary functions of the CLI Output Filtering feature are as follows:
•Pagination Control
oFor all show CLI commands, supports the enabling/disabling of paginated output. When
disabled, the requested output is displayed in its entirety. When enabled, the requested
output is displayed in a page-by-page manner such that the display does not scroll
beyond the end of the screen until the user presses a key to continue. The options --
More-- or (q)uit are displayed at the end of each page.
oIf pagination is enabled, pressing the return key will advance the display by a single line,
pressing q or Q will cause the pagination to stop, and pressing any other key will advance
the display by a whole page. No other configuring of these keys is possible.
Note: Although pagination is already supported by some D-LINK OS show commands, its
implementation is unique per command rather than being generic to all commands.
•Output Filtering
o“Grep”-like control used to modify the displayed output to show only the user-desired
content.
Filter the displayed output to include only those lines containing a specified string
match.
Filter the displayed output to omit only those lines containing a specified string
match.
Filter the displayed output to include only those lines including and following a
specified string match.
Filter the displayed output to include only a specified section of the content (e.g.,
“interface 0/1”) using a configurable end-of-section delimiter.
String matching should be case insensitive.
When enable, pagination also applies to filtered output.
Example
The following provides some examples of the extensions made to the CLI show.
show running-show config ?
<cr> Press enter to execute the command.
| Output filter options.
<scriptname> Script file name for writing active configuration.
all Show all the running configuration on the switch.
interface Display the running config for specified interface on
the switch.

3. D-LINK OS Modules
The D-LINK OS software is composed of flexible modules that can be utilized in a variety of combinations
in order to support advanced Layer 2/3/4 products. The installed modules determine the commands and
command modes available on your switch. Additionally, please note that the output fields for some show
commands might change depending upon the modules included in the D-LINK OS software.
The following modules are included in the D-LINK OS software suite:
•Switching (Layer 2)
•Data Center
•Routing (Layer 3)
•IPv6 Routing (Layer 3)
•Multicast
•BGP-4
•Quality of Service
•Management (CLI and SNMP)
Command Modes
Commands are grouped by the CLI into modes according to the command function, with specific D-LINK
OS software commands being supported by each of the command modes. As such, the commands for a
given mode are not available until the user switches to that particular mode, with the exception of the
commands for the User EXEC mode. The User EXEC mode commands can also be executed in the
Privileged EXEC mode.
To help the user identify the current mode, the command prompt changes for each different command
