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 and monitor the LED panel
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 DIS-200G 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.
NOTE: The Command Line Interface (CLI) provides the functionality of managing,
configuring, and monitoring all of the software features that are available on the Switch.
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.
NOTE: The default IP address of this switch is 10.90.90.90, with a subnet mask of
255.0.0.0.
NOTE: The default username and password is admin.

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:
DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch
• 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
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.

failure occurs if packets are formed with an incorrect community
string

Voice VLAN
Figure 6-31 Voice VLAN Global window
Voice VLAN Global
Voice VLAN is a VLAN used to carry voice traffic from IP phone. Because the sound quality of an IP
phone call will be deteriorated if the data is unevenly sent, the quality of service (QoS) for voice traffic
shall be configured to ensure the transmission priority of voice packet is higher than normal traffic.
The switches determine whether a received packet is a voice packet by checking its source MAC
address. If the source MAC addresses of packets comply with the organizationally unique identifier (OUI)
addresses configured by the system, the packets are determined as voice packets and transmitted in
voice VLAN.

Spanning Tree
This Switch supports three versions of the Spanning Tree Protocol: 802.1D-1998 STP, 802.1D-2004
Rapid STP, and 802.1Q- 2005 MSTP. 802.1D-1998 STP will be familiar to most networking professionals.
However, since 802.1D-2004 RSTP and 802.1Q-2005 MSTP have been recently introduced to D -Link
managed Ethernet switches, a brief introduction to the technology is provided below followed by a
description of how to set up 802.1D-1998 STP, 802.1D-2004 RSTP, and 802.1Q-2005 MSTP.
802.1Q-2005 MSTP
Multiple Spanning Tree Protocol, or MSTP, is a standard defined by the IEEE community that allows
multiple VLANs to be mapped to a single spanning tree instance, which will provide multiple pathways
across the network. Therefore, these MSTP configurations will balance the traffic load, preventing wide
scale disruptions when a single spanning tree instance fails. This will allow for faster convergences of
new topologies for the failed instance. Frames designated for these VLANs will be processed quickly and
completely throughout interconnected bridges utilizing any of the three spanning tree protocols (STP,
RSTP or MSTP).
This protocol will also tag BPDU packets so receiving devices can distinguish spanning tree instances,
spanning tree regions and the VLANs associated with them. An MSTI ID will classify these instances.
MSTP will connect multiple spanning trees with a Common and Internal Spanning Tree (CIST). The CIST
will automatically determine each MSTP region, its maximum possible extent and will appear as one
virtual bridge that runs a single spanning tree. Consequentially, frames assigned to different VLANs will
follow different data routes within administratively established regions on the network, continuing to allow
simple and full processing of frames, regardless of administrative errors in defining VLANs and their
respective spanning trees.
Each switch utilizing the MSTP on a network will have a single MSTP configuration that will have the
following three attributes:
A configuration name defined by an alphanumeric string of up to 32 characters (defined in the MST
Configuration Identification window in the Configuration Name field).
A configuration revision number (named here as a Revision Level and found in the MST
Configuration Identification window) and;
A 4094-element table (defined here as a VID List in the MST Configuration Identification window),
which will associate each of the possible 4094 VLANs supported by the Switch for a given instance.
To utilize the MSTP function on the Switch, three steps need to be taken:
The Switch must be set to the MSTP setting (found in the STP Bridge Global Settings window in the
STP Version field)
The correct spanning tree priority for the MSTP instance must be entered (defined here as a Priority
in the MSTI Config Information window when configuring MSTI ID settings).
VLANs that will be shared must be added to the MSTP Instance ID (defined here as a VID List in
the MST Configuration Identification window when configuring an MSTI ID settings).
802.1D-2004 Rapid Spanning Tree
The Switch implements three versions of the Spanning Tree Protocol, the Multiple Spanning Tree
Protocol (MSTP) as defined by the IEEE 802.1Q-2005, the Rapid Spanning Tree Protocol (RSTP) as
defined by the IEEE 802.1D-2004 specification and a version compatible with the IEEE 802.1D -1998
STP. RSTP can operate with legacy equipment implementing IEEE 802.1D-1998; however the
advantages of using RSTP will be lost.
The IEEE 802.1D-2004 Rapid Spanning Tree Protocol (RSTP) evolved from the 802.1D-1998 STP
standard. RSTP was developed in order to overcome some limitations of STP that impede the function of
some recent switching innovations, in particular, certain Layer 3 functions that are increasingly handled
67
Page 75
DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch
by Ethernet switches. The basic function and much of the terminology is the same as STP. Most of the
settings configured for STP are also used for RSTP. This section introduces some new Spanning Tree
concepts and illustrates the main differences between the two protocols.
Port Transition States
An essential difference between the three protocols is in the way ports transition to a forwarding state and
in the way this transition relates to the role of the port (forwarding or not forwarding) in the topology.
MSTP and RSTP combine the transition states disabled, blocking and listening used in 802.1D-1998 and
creates a single state Discarding. In either case, ports do not forward packets. In the STP port transition
states disabled, blocking or listening or in the RSTP/MSTP port state discarding, there is no functional
difference, the port is not active in the network topology. Table 7-3 below compares how the three
protocols differ regarding the port state transition.
All three protocols calculate a stable topology in the same way. Every segment will have a single path to
the root bridge. All bridges listen for BPDU packets. However, BPDU packets are sent more frequently with every Hello packet. BPDU packets are sent even if a BPDU packet was not received. Therefore,
each link between bridges is sensitive to the status of the link. Ultimately, this difference results in faster
detection of failed links, and thus faster topology adjustment. A drawback of 802.1D-1998 is this absence
of immediate feedback from adjacent bridges.
802.1Q-2005 MSTP 802.1D-2004 RSTP 802.1D-1998 STP Forwarding Learning
Disabled Disabled Disabled No No
Discarding Discarding Blocking No No
Discarding Discarding Listening No No
Learning Learning Learning No Yes
Forwarding Forwarding Forwarding Yes Yes
RSTP is capable of a more rapid transition to a forwarding state - it no longer relies on timer
configurations - RSTP compliant bridges are sensitive to feedback from other RSTP compliant bridge
links. Ports do not need to wait for the topology to stabilize before transitioning to a forwarding state. In
order to allow this rapid transition, the protocol introduces a new variable: the edge port.
Edge Port
The edge port is a configurable designation used for a port that is directly connected to a segment where
a loop cannot be created. An example would be a port connected directly to a single work- station. Ports
that are designated as edge ports transition to a forwarding state immediately without going through the
listening and learning states. An edge port loses its status if it receives a BPDU packet, immediately
becoming a normal spanning tree port.
802.1D-1998/802.1D-2004/802.1Q-2005 Compatibility
MSTP or RSTP can interoperate with legacy equipment and is capable of automatically adjusting BPDU
packets to 802.1D -1998 format when necessary. However, any segment using 802.1D -1998 STP will not
benefit from the rapid transition and rapid topology change detection of MSTP or RSTP. The protocol also
provides for a variable used for migration in the event that legacy equipment on a segment is updated to
use RSTP or MSTP.
The Spanning Tree Protocol (STP) operates on two levels:
1. On the switch level, the settings are globally implemented.
2. On the port level, the settings are implemented on a per-user-defined group of ports basis.

change to the non-port-fast state. In the Disabled mode, the port
will always be in the non-port-fast state. It will always wait for the
forward-time delay to change to the forwarding state. In the Edge
mode, the port will directly change to the spanning-tree forwarding
state when a link-up occurs without waiting for the forward-time
delay. If the interface receives a BPDU later, its operation state
changes to the non-port-fast state. By default, this option is
Network.

Figure 6-48 Example of Port Trunk Group
Link Aggregation
Understanding Port Trunk Groups
Port trunk groups are used to combine a number of ports together to make a single high-bandwidth data
pipeline. The Switch supports up to 6 port trunk groups with 1 to 8 ports in each group.
The Switch treats all ports in a trunk group as a single port. Data transmitted to a specific host
(destination address) will always be transmitted over the same port in a trunk group. This allows packets
in a data stream to arrive in the same order they were sent.
Link aggregation allows several ports to be grouped together and to act as a single link. This gives a
bandwidth that is a multiple of a single link's bandwidth.
Link aggregation is most commonly used to link a bandwidth intensive network device or devices, such as
a server, to the backbone of a network.
The Switch allows the creation of up to 6 link aggregation groups, each group consisting of 1 to 8 links
(ports). Each port can only belong to a single link aggregation group.
All of the ports in the group must be members of the same VLAN, and their STP status, static multicast,
traffic control; traffic segmentation and 802.1p default priority configurations must be identical. Further,
the LACP aggregated links must all be of the same speed and should be configured as full duplex.
Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the
group causes the network traffic to be directed to the remaining links in the group.
78
Page 86
DIS-200G Series Industrial Gigabit Ethernet Smart Managed Switch
Figure 6-49 Link Aggregation window
The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch level. On the
port level, the STP will use the port parameters calculation of port cost and in determining the state of the
link aggregation group. If two redundant link aggregation groups are configured on the Switch, STP will
block one entire group; in the same way STP will block a single port that has a redundant link.
NOTE: If any ports within the trunk group become disconnected, packets intended for the

IGMP Snooping
Internet Group Management Protocol (IGMP) snooping allows the Switch to recognize IGMP queries and
reports sent between network stations or devices and an IGMP host.
IGMP Snooping Settings
In order to use IGMP Snooping it must first be enabled for the entire Switch under IGMP Global Settings
at the top of the window. You may then fine-tune the settings for each VLAN by clicking the corresponding
Edit button. When enabled for IGMP snooping, the Switch can open or close a port to a specific multicast
group member based on IGMP messages sent from the device to the IGMP host or vice versa. The
Switch monitors IGMP messages and discontinues forwarding multicast packets when there are no
longer hosts requesting that they continue.
To view the following window, click L2 Features > L2 Multicast Control > IGMP Snooping > IGMP

MLD Snooping
Multicast Listener Discovery (MLD) Snooping is an IPv6 function used similarly to IGMP snooping in IPv4.
It is used to discover ports on a VLAN that are requesting multicast data. Instead of flooding all ports on a
selected VLAN with multicast traffic, MLD snooping will only forward multicast data to ports
that wish to receive this data through the use of queries and reports produced by the requesting ports and
the source of the multicast traffic.
MLD snooping is accomplished through the examination of the layer 3 part of an MLD control packet
transferred between end nodes and a MLD router. When the Switch discovers that this route is requesting
multicast traffic, it adds the port directly attached to it into the correct IPv6 multicast table, and begins the
process of forwarding multicast traffic to that port. This entry in the multicast routing table records the
port, the VLAN ID, and the associated multicast IPv6 multicast group address, and then considers this
port to be an active listening port. The active listening ports are the only ones to receive multicast group
data.
MLD Control Messages
Three types of messages are transferred between devices using MLD snooping. These three messages
are all defined by four ICMPv6 packet headers, labeled 130, 131, 132, and 143.
1. Multicast Listener Query – Similar to the IGMPv2 Host Membership Query for IPv4, and labeled
as 130 in the ICMPv6 packet header, this message is sent by the router to ask if any link is
requesting multicast data. There are two types of MLD query messages emitted by the router. The
General Query is used to advertise all multicast addresses that are ready to send multicast data to
all listening ports, and the Multicast Specific query, which advertises a specific multicast address
that is also ready. These two types of messages are distinguished by a multicast destination
address located in the IPv6 header and a multicast address in the Multicast Listener Query
Message.
2. Multicast Listener Report, Version 1 – Comparable to the Host Membership Report in IGMPv2,
and labeled as 131 in the ICMP packet header, this message is sent by the listening port to the
Switch stating that it is interested in receiving multicast data from a multicast address in response to
the Multicast Listener Query message.
3. Multicast Listener Done – Akin to the Leave Group Message in IGMPv2, and labeled as 132 in the
ICMPv6 packet header, this message is sent by the multicast listening port stating that it is no longer
interested in receiving multicast data from a specific multicast group address, therefore stating that it
is “done” with the multicast data from this address. Once this message is received by the Switch, it
will no longer forward multicast traffic from a specific multicast group address to this listening port.
4. Multicast Listener Report, Version 2 – Comparable to the Host Membership Report in IGMPv3,
and labeled as 143 in the ICMP packet header, this message is sent by the listening port to the
Switch stating that it is interested in receiving multicast data from a multicast address in response to
the Multicast Listener Query message.

Parameter Description
From Port / To Port Select the appropriate port range used for the configuration here.
Scheduler Method Select the scheduler method that will be applied to the specified

Weighted Round-Robin (WRR). By default, the output queue
scheduling algorithm is WRR.
To set a CoS queue in the SP mode, any higher priority CoS
queue must also be in the strict priority mode.
WRR operates by transmitting permitted packets into the transmit
queue in a round robin order. Initially, each queue sets its weight
to a configurable weighting. Every time a packet from a higher
priority CoS queue is sent, the corresponding weight is subtracted
by 1 and the packet in the next lower CoS queue will be serviced.
When the weight of a CoS queue reaches zero, the queue will not
be serviced until its weight is replenished. When weights of all CoS
queues reach 0, the weights get replenished at a time.
