1. Introduction
This manual’s command descriptions are based on the software release 1.30. The commands listed
here are the subset of commands that are supported by the DGS-1510 Series SmartPro switch.
Audience
This reference manual is intended for network administrators and other IT networking professionals
responsible for managing the switch by using the Web User Interface (Web UI). The Web UI is the
secondary management interface to the DGS-1510 Series switch, which will be generally be referred
to simply as “the Switch” within this manual. This manual is written in a way that assumes that you
already have the experience and knowledge of Ethernet and modern networking principles for Local
Area Networks.
Other Documentation
The documents below are a further source of information in regards to configuring and
troubleshooting the switch. All the documents are available either from the CD, bundled with this
switch, or from the D-Link website. Other documents related to this switch are:

Conventions
Notes, Notices, and Cautions
Below are examples of the three types of indicators used in this manual. When administering your
switch using the information in this document, you should pay special attention to these indicators.
Each example below provides an explanatory remark regarding each type of indicator.

Web User Interface (Web UI)
Management Options
The Switch provides multiple access platforms that can be used to configure, manage and monitor
networking features available on the Switch. Currently there are three management platforms
available and they are described below.
The Command Line Interface (CLI) through the RJ45 Console port or remote Telnet
The Switch can be managed, out-of-band, by using the console port on the front panel of the Switch.
Alternatively, the Switch can also be managed, in-band, by using a Telnet connection to any of the
LAN ports on the Switch. The command line interface provides complete access to all switch
management features.
SNMP-based Management
The Switch can be managed with an SNMP-compatible console program. The Switch supports SNMP
version 1.0, version 2.0 and version 3.0. The SNMP agent decodes the incoming SNMP messages
and responds to requests with MIB objects stored in the database. The SNMP agent updates the MIB
objects to generate statistics and counters.
Web-based Management Interface
After successfully installing the Switch, the user can configure the Switch, monitor the LED panel, and
display statistics graphically using a Web browser, such as Microsoft® Internet Explorer, Mozilla
Firefox, Safari, or Google Chrome.
Connecting using the Web User Interface
Most software functions of the DGS-1510 Series switches can be managed, configured and monitored
via the embedded web-based (HTML) interface. Manage the Switch from remote stations anywhere
on the network through a standard web browser. The web browser acts as a universal access tool
and can communicate directly with the Switch using the HTTP or HTTPS protocol.
Logging onto the Web Manager
To access the Web User Interface, simply open a standard web browser on the management PC and
enter the Switch’s default IP address into the address bar of the browser and press the Enter key.

Flow Control
Select to either turn flow control On or Off here. Ports configured for
full-duplex use 802.3x flow control, half-duplex ports use backpressure flow control, and Auto ports use an automatic selection of
the two.
Duplex
Select the duplex mode used here. Options to choose from are
Auto, Half, and Full.
Speed
Select the port speed option here. This option will manually force
the connected on the selected port to only connect at the speed
specified here. Options to choose from are Auto, 10M, 100M,
1000M, 1000M Master, 1000M Slave, and 10G. The Switch allows
users to configure two types of gigabit connections; 1000M Master
and 1000M Slave which refer to connections running a 1000BASE-
T cable for connection between the Switch port and another device
capable of a gigabit connection. The master setting (1000M Master)
will allow the port to advertise capabilities related to duplex, speed
and physical layer type. The master setting will also determine the
master and slave relationship between the two connected physical
layers. This relationship is necessary for establishing the timing
control between the two physical layers. The timing control is set on
a master physical layer by a local source. The slave setting (1000M
Slave) uses loop timing, where the timing comes from a data stream
received from the master. If one connection is set for 1000M
Master, the other side of the connection must be set for 1000M
Slave. Any other configuration will result in a link down status for
both ports.
Capability Advertised
When the Speed is set to Auto, these capabilities are advertised
during auto-negotiation.

PoE (DGS-1510-28P and DGS-1510-28XMP Only)
The DGS-1510-28P and DGS-1510-28XMP switches support Power over Ethernet (PoE) as defined
by the IEEE 802.3af and 802.3at. All ports can support PoE up to 30W. Ports 1-24 can supply about
48 VDC power to Powered Devices (PDs) over Category 5 or Category 3 UTP Ethernet cables. The
Switch follows the standard PSE (Power Sourcing Equipment) pin-out Alternative A, whereby power is
sent out over pins 1, 2, 3 and 6. The Switches work with all D-Link 802.3af capable devices.
The Switch includes the following PoE features:
Auto-discovery recognizes the connection of a PD (Powered Device) and automatically sends
power to it.
The Auto-disable feature occurs under two conditions: firstly, if the total power consumption
exceeds the system power limit; and secondly, if the per port power consumption exceeds the
per port power limit.
Active circuit protection automatically disables the port if there is a short. Other ports will remain
active.

SNMP
Simple Network Management Protocol (SNMP) is an OSI Layer 7 (Application Layer) designed
specifically for managing and monitoring network devices. SNMP enables network management
stations to read and modify the settings of gateways, routers, switches, and other network devices.
Use SNMP to configure system features for proper operation, monitor performance and detect
potential problems in the Switch, switch group or network.
Managed devices that support SNMP include software (referred to as an agent), which runs locally on
the device. A defined set of variables (managed objects) is maintained by the SNMP agent and used
to manage the device. These objects are defined in a Management Information Base (MIB), which
provides a standard presentation of the information controlled by the on-board SNMP agent. SNMP
defines both the format of the MIB specifications and the protocol used to access this information over
the network.
The Switch supports the SNMP versions 1, 2c, and 3. The three versions of SNMP vary in the level of
security provided between the management station and the network device.
In SNMP v.1 and v.2, user authentication is accomplished using ‘community strings’, which function
like passwords. The remote user SNMP application and the Switch SNMP must use the same
community string. SNMP packets from any station that has not been authenticated are ignored
(dropped).
The default community strings for the Switch used for SNMP v.1 and v.2 management access are:
public – Allows authorized management stations to retrieve MIB objects.
private – Allows authorized management stations to retrieve and modify MIB objects.
SNMPv3 uses a more sophisticated authentication process that is separated into two parts. The first
part is to maintain a list of users and their attributes that are allowed to act as SNMP managers. The
second part describes what each user on that list can do as an SNMP manager.
The Switch allows groups of users to be listed and configured with a shared set of privileges. The
SNMP version may also be set for a listed group of SNMP managers. Thus, you may create a group
of SNMP managers that are allowed to view read-only information or receive traps using SNMPv1
32
Page 41
DGS-1510 Series Gigabit Ethernet SmartPro Switch Web UI Reference Guide
while assigning a higher level of security to another group, granting read/write privileges using
SNMPv3.
Using SNMPv3 individual users or groups of SNMP managers can be allowed to perform or be
restricted from performing specific SNMP management functions. The functions allowed or restricted
are defined using the Object Identifier (OID) associated with a specific MIB. An additional layer of
security is available for SNMPv3 in that SNMP messages may be encrypted. To read more about how
to configure SNMPv3 settings for the Switch read the next section.
Traps
Traps are messages that alert network personnel of events that occur on the Switch. The events can
be as serious as a reboot (someone accidentally turned OFF the Switch), or less serious like a port
status change. The Switch generates traps and sends them to the trap recipient (or network manager).
Typical traps include trap messages for Authentication Failure, Topology Change and
Broadcast\Multicast Storm.
MIBs
The Switch in the Management Information Base (MIB) stores management and counter information.
The Switch uses the standard MIB-II Management Information Base module. Consequently, values
for MIB objects can be retrieved from any SNMP-based network management software. In addition to
the standard MIB-II, the Switch also supports its own proprietary enterprise MIB as an extended
Management Information Base. Specifying the MIB Object Identifier may also retrieve the proprietary
MIB. MIB values can be either read-only or read-write.
The Switch incorporates a flexible SNMP management for the switching environment. SNMP
management can be customized to suit the needs of the networks and the preferences of the network
administrator. Use the SNMP V3 menus to select the SNMP version used for specific tasks.
The Switch supports the Simple Network Management Protocol (SNMP) versions 1, 2c, and 3. The
administrator can specify the SNMP version used to monitor and control the Switch. The three
versions of SNMP vary in the level of security provided between the management station and the
network device.
SNMP settings are configured using the menus located on the SNMP V3 folder of the Web manager.
Workstations on the network that are allowed SNMP privileged access to the Switch can be restricted
with the Management Station IP Address menu.

the device receives an SNMP message that is not properly
authenticated. The authentication method depends on the version of
SNMP being used. For SNMPv1 or SNMPv2c, authentication failure
occurs if packets are formed with an incorrect community string. For
SNMPv3, authentication failure occurs if packets are formed with an
incorrect SHA/MD5 authentication key.

DNS
Computer users usually prefer to use text names for computers for which they may want to open a
connection. Computers themselves, require 32 bit IP addresses. Somewhere, a database of network
devices’ text names and their corresponding IP addresses must be maintained.

Parameter
Description
IP Domain Lookup
Select this option to enable or disable the DNS to carry out the
domain name resolution.
The Domain Name System (DNS) is used to map names to IP addresses throughout the Internet and
has been adapted for use within intranets. For two DNS servers to communicate across different
subnets, the DNS Relay of the Switch must be used. The DNS servers are identified by IP addresses.
Mapping Domain Names to Addresses
Name-to-address translation is performed by a program called a Name server. The client program is
called a Name resolver. A Name resolver may need to contact several Name servers to translate a
name to an address.
The Domain Name System (DNS) servers are organized in a somewhat hierarchical fashion. A single
server often holds names for a single network, which is connected to a root DNS server - usually
maintained by an ISP.
Domain Name Resolution
The domain name system can be used by contacting the name servers one at a time, or by asking the
domain name system to do the complete name translation. The client makes a query containing the
name, the type of answer required, and a code specifying whether the domain name system should
do the entire name translation, or simply return the address of the next DNS server if the server
receiving the query cannot resolve the name.
When a DNS server receives a query, it checks to see if the name is in its sub domain. If it is, the
server translates the name and appends the answer to the query, and sends it back to the client. If the
DNS server cannot translate the name, it determines what type of name resolution the client
requested. A complete translation is called recursive resolution and requires the server to contact
other DNS servers until the name is resolved. Iterative resolution specifies that if the DNS server
cannot supply an answer, it returns the address of the next DNS server the client should contact.
Each client must be able to contact at least one DNS server, and each DNS server must be able to
contact at least one root server.
The address of the machine that supplies domain name service is often supplied by a DHCP or
BOOTP server, or can be entered manually and configured into the operating system at startup.

number and firmware numbers are also fixed. A compatible issue will occur in the event that the
configuration file or firmware size exceeds the originally designed size.
Flash File System in our system:
The Flash File System is used to provide the user with flexible file operation on the Flash. All the
firmware, configuration information and system log information are stored in the Flash as files. This

Physical Stacking
Figure 4-53 File System - Copy window
The Switch supports switch stacking, where a set of 6 switches can be combined to be managed by
one IP address through Telnet, the Web User Interface, the RJ45 console port, or through SNMP.
Each switch of this series has two stacking ports located at the front of the device, which can be used
to connect other devices and make them stack together. After adding these stacking ports, the user
may connect these ports together using fiber cables or Direct Attach Cables (DAC) in one of two
possible topologies.
Duplex Chain – As shown in Figure 4-54, The Duplex Chain topology stacks switches together in a
chain-link format. Using this method, data transfer is only possible in one direction and if there is a
break in the chain, then data transfer will obviously be affected.
Duplex Ring – As shown in Error! Reference source not found., the Duplex Ring stacks switches
n a ring or circle format where data can be transferred in two directions. This topology is very resilient
due to the fact that if there is a break in the ring, data can still be transferred through the stacking
cables between switches in the stack.

Figure 4-55 Switches stacked in a Duplex Ring
67
Page 76
DGS-1510 Series Gigabit Ethernet SmartPro Switch Web UI Reference Guide
Within each of these topologies, each switch plays a role in the Switch stack. These roles can be set
by the user per individual Switch, or if desired, can be automatically determined by the Switch stack.
Three possible roles exist when stacking with the Switch.
Primary Master – The Primary Master is the leader of the stack. It will maintain normal operations,
monitor operations and the running topology of the Stack. This switch will also assign Stack Unit IDs,
synchronize configurations and transmit commands to remaining switches in the switch stack. The
Primary Master can be manually set by assigning this Switch the highest priority (a lower number
denotes a higher priority) before physically assembling the stack, or it can be determined
automatically by the stack through an election process which determines the lowest MAC address and
then will assign that switch as the Primary Master, if all priorities are the same. The Primary master
are physically displayed by the seven segment LED to the far right on the front panel of the switch
where this LED will flash between its given Box ID and ‘H’.
Backup Master – The Backup Master is the backup to the Primary Master, and will take over the
functions of the Primary Master if the Primary Master fails or is removed from the Stack. It also
monitors the status of neighboring switches in the stack, will perform commands assigned to it by the
Primary Master and will monitor the running status of the Primary Master. The Backup Master can be
set by the user by assigning this Switch the second highest priority before physically assembling the
stack, or it can be determined automatically by the stack through an election process which
determines the second lowest MAC address and then will assign that switch as the Backup Master, if
all priorities are the same. The Backup master are physically displayed by the seven segment LED to
the far right on the front panel of the switch where this LED will flash between its given Box ID and ‘h’.
Slave – Slave switches constitute the rest of the switch stack and although not Primary or Backup
Masters, they can be placed into these roles when these other two roles fail or are removed from the
stack. Slave switches perform operations requested by the master, monitor the status of neighbor
switches in the stack and the stack topology and adhere to the Backup Master’s commands once it
becomes a Primary Master. Slave switches will do a self-check to determine if it is to become the
Backup Master if the Backup Master is promoted to the Primary Master, or if the Backup Master fails
or is removed from the switch stack. If both Primary and Backup masters fail, or are removed from the
Switch stack, it will determine if it is to become the Primary Master. These roles will be determined,
first by priority and if the priority is the same, the lowest MAC address.
Once switches have been assembled in the topology desired by the user and powered on, the stack
will undergo three processes until it reaches a functioning state.
Initialization State – This is the first state of the stack, where the runtime codes are set and initialized
and the system conducts a peripheral diagnosis to determine each individual switch is functioning
properly.
Master Election State – Once the codes are loaded and initialized, the stack will undergo the Master
Election State where it will discover the type of topology used, elect a Primary Master and then a
Backup Master.
Synchronization State – Once the Primary Master and the Backup Master have been established,
the Primary Master will assign Stacking Unit IDs to switches in the stack, synchronize configurations
for all switches and then transmit commands to the rest of the switches based on the users
configurations of the Primary Master.
Once these steps have been completed, the switch stack will enter a normal operating mode.
Stack Switch Swapping
The stacking feature of the Switch supports “hot swapping” of switches in and out of the running stack.
Users may remove or add switches to the stack without powering down or largely affecting the
transfer of data between switches in the stack, with a few minor provisions.
When switches are “hot inserted” into the running stack, the new switch may take on the Primary
Master, Backup Master or Slave role, depending on configurations set on the newly added switch,
such as configured priority or MAC address. Yet, if adding two stacks together that have both
previously undergone the election process, and therefore both have a Primary Master and a Backup
master, a new Primary Master will be elected from one of the already existing Primary Masters, based
on priority or MAC address. This Primary Master will take over all of the Primary Master’s roles for all
new switches that were hot inserted. This process is done using discovery packets that circulate
through the switch stack every 1.5 seconds until the discovery process has been completed.
68
Page 77
DGS-1510 Series Gigabit Ethernet SmartPro Switch Web UI Reference Guide
NOTE: If there is a Box ID conflict when the stack is in the discovery phase, the device will
enter a special standalone topology mode. Users can only get device information,
configure Box IDs, save and reboot. All stacking ports will be disabled and an error
message will be produced on the local console port of each device in the stack.
Users must reconfigure Box IDs and reboot the stack.
Parameter
Description
Stacking Mode
Select this option to enable or disable the stacking mode.
The “hot remove” action means removing a device from the stack while the stack is still running. The
hot removal is detected by the stack when it fails to receive heartbeat packets during its specified
interval from a device, or when one of the stacking ports links is down. Once the device has been
removed, the remaining switches will update their stacking topology database to reflect the change.
Any one of the three roles, Primary Master, Backup Master or Slave, may be removed from the stack,
yet different processes occur for each specific device removal.
If a Slave device has been removed, the Primary Master will inform other switches of the hot remove
of this device through the use of unit leave messages. Switches in the stack will clear the
configurations of the unit removed, and dynamically learned databases, such as ARP, will be cleared
as well.
If the Backup Master has been hot removed, a new Backup Master will be chosen through the
election process previously described. Switches in the stack will clear the configurations of the unit
removed, and dynamically learned databases, such as ARP, will be cleared as well. Then the Backup
Master will begin backing up the Primary Master when the database synchronization has been
completed by the stack.
If the Primary Master is removed, the Backup Master will assume the Primary Master’s role and a new
Backup Master will be chosen using the election process. Switches in the stack will clear the
configurations of the unit removed, and dynamically learned databases, such as ARP, will be cleared
as well. The new Primary Master will inherit the MAC and IP address of the previous Primary Master
to avoid conflict within the stack and the network itself.
If both the Primary Master and the Backup Master are removed, the election process is immediately
processed, and a new Primary Master and Backup Master are determined. Switches in the stack will
clear the configurations of the units removed, and dynamically learned databases, such as ARP, will
be cleared as well. Static switch configurations still remain in the database of the remaining switches
in the stack and those functions will not be affected.

Virtual Stacking (SIM)
D-Link Single IP Management (SIM) is a concept that will stack switches together over Ethernet
instead of using stacking ports or modules. There are some advantages in implementing the Single IP
Management feature:
1. SIM can simplify management of small workgroups or wiring closets while scaling the network to
handle increased bandwidth demand.
2. SIM can reduce the number of IP address needed in your network.
3. SIM can eliminate any specialized cables for stacking connectivity and remove the distance
barriers that typically limit your topology options when using other stacking technology.
Switches using D-Link Single IP Management (labeled here as SIM) must conform to the following
rules:
SIM is an optional feature on the Switch and can easily be enabled or disabled through the
Command Line Interface or Web Interface. SIM grouping has no effect on the normal operation of
the Switch in the user’s network.
There are three classifications for switches using SIM. The Commander Switch (CS), which is
the master switch of the group, Member Switch (MS), which is a switch that is recognized by the
CS a member of a SIM group, and a Candidate Switch (CaS), which is a Switch that has a
physical link to the SIM group but has not been recognized by the CS as a member of the SIM
group.
A SIM group can only have one Commander Switch (CS).
A SIM group accepts up to 32 switches (numbered 1-32), not including the Commander Switch
(numbered 0).
Members of a SIM group cannot cross a router.
There is no limit to the number of SIM groups in the same IP subnet (broadcast domain);
however a single switch can only belong to one group.
If multiple VLANs are configured, the SIM group will only utilize the management VLAN on any
switch.
SIM allows intermediate devices that do not support SIM. This enables the user to manage
switches that are more than one hop away from the CS.
The SIM group is a group of switches that are managed as a single entity. The Switch may take on
three different roles:
70
Page 79
DGS-1510 Series Gigabit Ethernet SmartPro Switch Web UI Reference Guide
1. Commander Switch (CS) – This is a switch that has been manually configured as the controlling
device for a group, and takes on the following characteristics:
a. It has an IP Address.
b. It is not a command switch or member switch of another Single IP group.
c. It is connected to the member switches through its management VLAN.
2. Member Switch (MS) – This is a switch that has joined a single IP group and is accessible from
the CS, and it takes on the following characteristics:
a. It is not a CS or MS of another IP group.
b. It is connected to the CS through the CS management VLAN.
3. Candidate Switch (CaS) – This is a switch that is ready to join a SIM group but is not yet a
member of the SIM group. The Candidate Switch may join the SIM group of the Switch by
manually configuring it to be a MS of a SIM group. A switch configured as a CaS is not a member
of a SIM group and will take on the following characteristics:
a. It is not a CS or MS of another Single IP group.
b. It is connected to the CS through the CS management VLAN
The following rules also apply to the above roles:
Each device begins in a Candidate state.
A CS must change its role to CaS and then to MS, to become a MS of a SIM group. Thus, the CS
cannot directly be converted to a MS.
The user can manually configure a CS to become a CaS.
A MS can become a CaS by:
o Being configured as a CaS through the CS.
o If report packets from the CS to the MS time out.
The user can manually configure a CaS to become a CS
The CaS can be configured through the CS to become a MS.
After configuring one switch to operate as the CS of a SIM group, additional DGS-1510 Series
switches may join the group by manually configuring the Switch to be a MS. The CS will then serve as
the in band entry point for access to the MS. The CS’s IP address will become the path to all MS’s of
the group and the CS’s Administrator’s password, and/or authentication will control access to all MS’s
of the SIM group.
With SIM enabled, the applications in the CS will redirect the packet instead of executing the packets.
The applications will decode the packet from the administrator, modify some data, and then send it to
the MS. After execution, the CS may receive a response packet from the MS, which it will encode and
send it back to the administrator.
When a CaS becomes a MS, it automatically becomes a member of the first SNMP community
(includes read/write and read only) to which the CS belongs. However, if a MS has its own IP address,
it can belong to SNMP communities to which other switches in the group, including the CS, do not
belong.
Upgrade to v1.61
To better improve SIM management, the DGS-1510 Series switches have been upgraded to version
1.61 in this release. Many improvements have been made, including:
1. The Commander Switch (CS) now has the capability to automatically rediscover member
switches that have left the SIM group, either through a reboot or web malfunction. This feature is
accomplished through the use of Discover packets and Maintenance packets that previously set
SIM members will emit after a reboot. Once a MS has had its MAC address and password saved
to the CS’s database, if a reboot occurs in the MS, the CS will keep this MS information in its
database and when a MS has been rediscovered, it will add the MS back into the SIM tree
automatically. No configuration will be necessary to rediscover these switches.
There are some instances where pre-saved MS switches cannot be rediscovered. For example, if the
Switch is still powered down, if it has become the member of another group, or if it has been
configured to be a Commander Switch, the rediscovery process cannot occur.
