INTRODUCTION
This section describes the features of the Switch, as well as giving some background information
about Ethernet/Fast Ethernet, Gigabit Ethernet, and switching technology.
Fast Ethernet Technology
The growing importance of LANs and the increasing complexity of desktop computing
applications are fueling the need for high performance networks. A number of high-speed LAN
technologies are proposed to provide greater bandwidth and improve client/server response
times. Among them, Fast Ethernet, or 100BASE-T, provides a non-disruptive, smooth evolution
from the current 10BASE-T technology. The dominating market position virtually guarantees
cost effective and high performance Fast Ethernet solutions in the years to come.
100Mbps Fast Ethernet is a standard specified by the IEEE 802.3 LAN committee. It is an
extension of the 10Mbps Ethernet standard with the ability to transmit and receive data at
100Mbps, while maintaining the Carrier Sense Multiple Access with Collision Detection
(CSMA/CD) Ethernet protocol.
Gigabit Ethernet Technology
Gigabit Ethernet is an extension of IEEE 802.3 Ethernet utilizing the same packet structure,
format, and support for CSMA/CD protocol, full duplex, flow control, and management objects,
but with a tenfold increase in theoretical throughput over 100Mbps Fast Ethernet and a one
hundred-fold increase over 10Mbps Ethernet. Since it is compatible with all 10Mbps and
100Mbps Ethernet environments, Gigabit Ethernet provides a straightforward upgrade without
wasting a company’s existing investment in hardware, software, and trained personnel.
The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to coping with
the network bottlenecks that frequently develop as computers and their busses get faster and
more users use applications that generate more traffic. Upgrading key components, such as your
backbone and servers to Gigabit Ethernet can greatly improve network response times as well as
significantly speed up the traffic between your subnets.
Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex
imaging, and similar data-intensive applications. Likewise, since data transfers occur 10 times
faster than Fast Ethernet, servers outfitted with Gigabit Ethernet NIC’s are able to perform 10
times the number of operations in the same amount of time.
In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effective
method to take advantage of today and tomorrow’s rapidly improving switching and routing

internetworking technologies. And with expected advances in the coming years in silicon
technology and digital signal processing that will enable Gigabit Ethernet to eventually operate
over unshielded twisted-pair (UTP) cabling, outfitting your network with a powerful 1000Mbpscapable backbone/server connection creates a flexible foundation for the next generation of
network technology products.
Switching Technology
Another key development pushing the limits of Ethernet technology is in the field of switching
technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet, Fast Ethernet, or Gigabit Ethernet LAN segments.
Switching is a cost-effective way of increasing the total network capacity available to users on a
local area network. A switch increases capacity and decreases network loading by making it
possible for a local area network to be divided into different segments which don’t compete with
each other for network transmission capacity, giving a decreased load on each.
The switch acts as a high-speed selective bridge between the individual segments. Traffic that
needs to go from one segment to another (from one port to another) is automatically forwarded
by the switch, without interfering with any other segments (ports). This allows the total network
capacity to be multiplied, while still maintaining the same network cabling and adapter cards.
For Fast Ethernet or Gigabit Ethernet networks, a switch is an effective way of eliminating
problems of chaining hubs beyond the “two-repeater limit.” A switch can be used to split parts of
the network into different collision domains, for example, making it possible to expand your Fast
Ethernet network beyond the 205-meter network diameter limit for 100BASE-TX networks.
Switches supporting both traditional 10Mbps Ethernet and 100Mbps Fast Ethernet are also ideal
for bridging between existing 10Mbps networks and new 100Mbps networks.
Switching LAN technology is a marked improvement over the previous generation of network
bridges, which were characterized by higher latencies. Routers have also been used to segment
local area networks, but the cost of a router and the setup and maintenance required make routers
relatively impractical. Today’s switches are an ideal solution to most kinds of local area network
congestion problems.
Features
The DES-6300 is a high performance modular switch platform that allows a customized array of
Layer 2 and Layer 3 functions to be easily installed and managed in a single device. The Switch
is ideal for expanding enterprise networks and environments where traffic volume and needs
fluctuate.

Installing Modules
The DES-6300 supports up to 6 modules that can be installed into the module bays. Networking
modules are warm-swappable, meaning they can be added and removed while power to the
switch is ON. After warm-swapping a networking module, the switch will automatically be
rebooted. Make sure to use the Save Changes command to save the current configuration to NVRAM before warm-swapping modules. The CPU module, however, is NOT hot-swappable.
Removing or inserting the CPU module while the power is on may cause irreparable damage to
the module and/or to the Switch itself. Further, make sure you have unplugged the power cord
from the removable power supply module before inserting or removing it from the Switch.
CAUTION: Due to the high energy present in this system, extreme caution
should be exercised whenever adding or removing system components. No
element of this system may be installed or removed except by an authorized
technician.
Figure 2- 3. Removing a Blank Slot Cover
Modules can be installed into any free slot, except the CPU module. The CPU module must be
installed in the uppermost (top) slot. To install a module, simply remove a blank slot cover and
slide the module along the guide rails until it snaps firmly in place.

Connecting a Terminal
The DES-6300 can perform basic switching functions without special configuration, but to use
the Switch’s advanced features you must first configure the unit through a terminal (a VT-100
serial data terminal or a computer running a VT-100 emulator). The connection is made through
the Switch’s Diagnostic RS-232 port, which is configured at the factory as follows:
Baud Rate: 115200
Data Bits: 8
Parity: none
Stop Bits: 1
Flow Control: none
The RS-232 port has a nine-socket D-shell connector with IBM-type DCE wiring, and can be
connected to the terminal using an off-the-shelf RS-232 cable with the proper connectors for the
terminal and the DES-6300.
Power on
Power up the DES-6300 as follows:
Make sure the power module is properly installed in the device.
Plug the device end of the supplied power cord firmly into the power inlet on the
DES-6300’s front panel of the redundant power supply.
Plug the outlet end of the power cord firmly into a suitable AC outlet.
Observe the DES-6300’s LED indicators to make sure the Switch is operating
correctly.
The DES-6300’s LED indicators operate as follows during a normal power-up:

All indicators blink momentarily to indicate a system reset.
The Power indicator flashes for about 20 seconds while the switch prepares its
run-time software and performs a self-test.
The Power indicator begins shining steadily, and the remaining indicators begin
reflecting port and system status.
Power Failure
As a precaution, the Switch should be unplugged in case of an impending power failure. When
power is resumed, plug the Switch back in.

Side Panels
The left side panel of the Switch contains four system fans. The right side panel contains heat
vents. The system fans are used to dissipate heat. The sides of the system also provide heat vents
to serve the same purpose. Do not block these openings, and leave adequate space at the rear and
sides of the Switch for proper ventilation. Be reminded that without proper heat dissipation and
air circulation, system components might overheat, which could lead to system failure.

CONNECTING THE SWITCH
This chapter describes how to connect the Switch to your Ethernet network as well as providing
an informational cable length table.
Switch To End Node
End nodes include PCs outfitted with a Network Interface Card (NIC) and most routers. For
twisted-pair (copper) connections, the RJ-45 UTP ports on NICs and most routers are MDI-II.
When using a normal straight-through cable, an MDI-II port must connect to an MDI-X port.
An end node can be connected to the Switch via a two-pair Category 3, 4, 5 UTP/STP straight
cable (be sure to use Category 5 UTP or STP cabling for 100BASE-TX Fast Ethernet
connections). The end node should be connected to any of the sixteen ports (1x - 16x) on the
10BASE-T/100BASE-TX module. The LED indicators for the port the end node is connected to
are lit according to the capabilities of the NIC. If LED indicators are not illuminated after
making a proper connection, check the PC’s LAN card, the cable, switch conditions, and
connections.
The DES Supports auto-MDI and therefore the user may connect a straight or crossover cable to
the switch and therefore the port will automatically configure itself to achieve a valid link to the
network.
The following LED indicator states are possible for an end node to switch connection:
1. The 100M indicators come ON for a 100 Mbps and stays OFF for 10 Mbps.
2. The Link/Act indicator lights up upon hooking up a PC that is powered on.
Switch To Hub or Switch
These connections can be accomplished at any port in either straight-through cable or a crossover
cable because the switch supports the Auto-MDI function.
• A 10BASE-T hub or switch can be connected to the Switch via a two-pair Category 3, 4
or 5 UTP/STP cable.
• A 100BASE-TX hub or switch can be connected to the Switch via a two-pair Category 5e
UTP/STP cable.
10BASE-T Device

SWITCH MANAGEMENT CONCEPTS
This chapter discusses many of the features used to manage the switch, and explains many
concepts and important points regarding these features. Configuring the Switch to implement
these concepts is discussed in detail in the next chapters.
IP Addresses and SNMP Community Names
Each Switch has its own IP Address, which is used for communication with an SNMP network
manager or other TCP/IP application (for example BOOTP, TFTP, etc.). You must provide the
switch with an IP Address to meet the specification of your networking address scheme.
In addition, you can also set an IP Address for a gateway router. This becomes necessary when
the network management station is located on a different IP network as the Switch, making it
necessary for management packets to go through a router to reach the network manager, and
vice-versa.
For security, you can set in the Switch a list of IP Addresses of the network managers that you
allow to manage the Switch. You can also change the default Community Name in the Switch
and set access rights of these Community Names.
Traps
Traps are messages that alert you 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 network manager (trap
managers). The following lists the types of events that can take place on the Switch.
System resets
Errors
Status changes
Topology changes
Operation
You can also specify which network managers may receive traps from the Switch by setting a list
of IP Addresses of the authorized network managers.
Trap managers are special users of the network who are given certain rights and access in
overseeing the maintenance of the network. Trap managers will receive traps sent from the
Switch; they must immediately take certain actions to avoid future failure or breakdown of the
network.
21
Page 31
Modular L3 Ethernet Switch User’s Guide
The following are trap types a trap manager will receive:
Cold Start – This trap signifies that the Switch has been powered up and
initialized such that software settings are reconfigured and hardware systems are
rebooted. A cold start is different from a factory reset.
Authentication Failure – This trap signifies that someone has tried to logon to
the switch using an invalid SNMP community name. The switch automatically
stores the source IP address of the unauthorized user.
Link Change Event – This trap is sent whenever the link of a port changes from
link up to link down or from link down to link up.
Power Fan1 Failure – This trap is sent whenever one of the two fans on a
redundant power supply module fails.
Power Fan2 Failure – This trap is sent whenever one of the two fans on a
redundant power supply module fails.
End TFTP – This trap is sent when TFTP service ends.
Abort TFTP – This trap is sent when TFTP service aborts.
Start TFTP
VLAN Dynamic Port Added – This trap is sent when a VLAN dynamic port is
added.
VLAN Dynamic Port Removed – This trap is sent when a VLAN dynamic port
is removed.
– This trap is sent when TFTP service starts.
MIBs
Management information and counters are stored in the Switch in the Management Information
Base (MIB). The Switch uses the standard MIB-II Management Information Base module.
Consequently, values for MIB objects can be retrieved from any SNMP-based network manager
software. In addition to the standard MIB-II, the Switch also supports its own proprietary
enterprise MIB as an extended Management Information Base. These MIBs may also be
retrieved by specifying the MIB’s Object-Identity (OID) at the network manager. MIB values
can be either read-only or read-write.
Read-only MIBs variables can be either constants that are programmed into the Switch, or
variables that change while the Switch is in operation. Examples of read-only constants are the
number of ports and types of ports. Examples of read-only variables are the statistics counters
such as the number of errors that have occurred, or how many kilobytes of data have been
received and forwarded through a port.
Read-write MIBs are variables usually related to user-customized configurations. Examples of
these are the Switch’s IP Address, Spanning Tree Algorithm parameters, and port status.
If you use a third-party vendors’ SNMP software to manage the Switch, a diskette listing the
Switch’s propriety enterprise MIBs can be obtained by request. If your software provides
functions to browse or modify MIBs, you can also get the MIB values and change them (if the
MIBs’ attributes permit the write operation). This process however can be quite involved, since
you must know the MIB OIDs and retrieve them one by one.
22
Page 32
Modular L3 Ethernet Switch User’s Guide
Packet Forwarding
The Switch learns the network configuration and uses this information to forward packets. This
reduces the traffic congestion on the network, because packets, instead of being transmitted to all
segments, are transmitted to the destination only. Example: if Port 1 receives a packet destined
for a station on Port 2, the Switch transmits that packet through Port 2 only, and transmits
nothing through the other ports.
Aging Time
The Aging Time is a parameter that affects the auto-learn process of the Switch in terms of the
network configuration. Dynamic Entries, which make up the auto-learned-node address, are aged
out of the address table according to the Aging Time that you set.
The Aging Time can be from 10 seconds to 9999 seconds. A very long Aging Time can result
with the out-of-date Dynamic Entries that may cause incorrect packet filtering/forwarding
decisions.
On the other hand, if the Aging Time is too short, many entries may be aged out soon, resulting
in a high percentage of received packets whose source addresses cannot be found in the address
table, in which case the Switch will broadcast the packet to all ports, negating many of the
benefits of having a switch.
Filtering Database
A switch uses a filtering database to segment the network and control communications between
segments. It also filters packets off the network for intrusion control (MAC Address filtering).
For port filtering, each port on the switch is a unique collision domain and the switch filters
(discards) packets whose destination lies on the same port as where it originated. This keeps
local packets from disrupting communications on other parts of the network.
For intrusion control, whenever a switch encounters a packet originating from or destined to a
MAC address defined by the user, the switch will discard the packet.
Filtering includes:
Dynamic filtering – Automatic learning and aging of MAC addresses and their location on the
network. Filtering occurs to keep local traffic confined to its segment.
MAC address filtering
network.
Filtering done by the Spanning Tree Protocol – Able to filter packets based on topology,
making sure that signal loops don’t occur.
Filtering done for VLAN integrity – Packets from a member of a VLAN (VLAN 2, for
example) destined for a device on another VLAN (VLAN 3) will be filtered.
– The manual entry of specific MAC addresses to be filtered from the
23

Modular L3 Ethernet Switch User’s Guide
Spanning Tree Algorithm
The Spanning Tree Algorithm (STA) in the Switch allows you to create alternative paths (with
multiple switches or other types of bridges) in your network. These backup paths are idle until
the Switch determines that a problem has developed in the primary paths. When a primary path
is lost, the switch providing the alternative path will automatically go into service with no
operator intervention. This automatic network reconfiguration provides maximum uptime to
network users. The concept of the Spanning Tree Algorithm is a complicated and complex
subject and must be fully researched and understood. Please read the following before making
any changes.
Network loop detection and prevention – With STA, there will be only one path between any
two LANs. If there is more than one path, forwarded packets will loop indefinitely. STA detects
any looped path and selects the path with the lowest path cost as the active path, while blocking
the other path and using it as the backup path.
Automatic topology re-configuration – When the path for which there is a backup path fails, the
backup path will be automatically activated, and STA will automatically re-configure the
network topology.
STA Operation Levels
STA operates on two levels: the bridge level and the port level. On the bridge level, STA
calculates the Bridge Identifier for each Switch, then sets the Root Bridge and the Designated
Bridges. On the port level, STA sets the Root Port and Designated Ports. Details are as follows:
On Bridge Level
Root Bridge – The switch with the lowest Bridge Identifier is the Root Bridge. Naturally, you
will want the Root Bridge to be the best switch among the switches in the loop to ensure the
highest network performance and reliability.
Bridge Identifier
and the MAC address of the switch. Example: 4 00 80 c8 00 01 00, where 4 is the Bridge
Priority. A lower Bridge Identifier results in a higher priority for the switch, and thus increases it
probably of being selected as the Root Bridge.
Designated Bridge
Path Cost to the Root Bridge is the Designated Bridge. It forwards data packets for that LAN
segment. In cases where all Switches have the same Root Path Cost, the switch with the lowest
Bridge Identifier becomes the Designated Bridge.
Root Path Cost
and the Root Path Costs of all the switches that the packet goes through. The Root Path Cost of
the Root Bridge is zero.
Bridge Priority – This is a parameter that users can set. The smaller the number you set, the
higher the Bridge Priority is. The higher the Bridge Priority, the better the chance the Switch will
be selected as the Root Bridge.
– This is the combination of the Bridge Priority (a parameter that you can set)
– From each LAN segment, the attached Bridge that has the lowest Root
– The Root Path Cost of a switch is the sum of the Path Cost of the Root Port
24
Page 34
Modular L3 Ethernet Switch User’s Guide
On The Port Level
Root Port – Each switch has a Root Port. This is the port that has the lowest Path Cost to the
Root Bridge. In case there are several such ports, then the one with the lowest Port Identifier is
the Root Port.
Designated Port
segment for which the switch is the Designated Bridge.
Port Priority – The smaller this number, the higher the Port Priority is. With higher Port
Priority, the higher the probability that the port will be selected as the Root Port.
Path Cost – This is a changeable parameter and may be modified according to the STA
specification. The 1000Mbps segment has an assigned Path Cost of 4, the 100Mbps segment has
an assigned Path Cost of 19, and each 10Mbps segment has an assigned Path Cost of 100, based
on the STA specifications.
– This is the port on each Designated Bridge that is attached to the LAN
User-Changeable STA Parameters
The factory default setting should cover the majority of installations. However, it is advisable to
keep the default settings as set at the factory, unless it is absolutely necessary. The user
changeable parameters in the Switch are as follows:
Bridge Priority – A Bridge Priority can be from 0 to 65535. 0 is equal to the highest Bridge
Priority.
Bridge Hello Time – The Hello Time can be from 1 to 10 seconds. This is the interval between
two transmissions of BPDU packets sent by the Root Bridge to tell all other Switches that it is
indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge,
the set Hello Time will be used if and when your Switch becomes the Root Bridge.
Note: The Hello Time cannot be longer than the Max. Age. Otherwise, a configuration error
will occur.
Bridge Max. Age – The Max. Age can be from 6 to 40 seconds. At the end of the Max. Age, if a
BPDU has still not been received from the Root Bridge, your Switch will start sending its own
BPDU to all other Switches for permission to become the Root Bridge. If it turns out that your
Switch has the lowest Bridge Identifier, it will become the Root Bridge.
Bridge Forward Delay – The Forward Delay can be from 4 to 30 seconds. This is the time any
port on the Switch spends in the listening state while moving from the blocking state to the
forwarding state.
Observe the following formulas when you set the above parameters:
Max. Age ≤ 2 x (Forward Delay - 1 second)
Max. Age ≥ 2 x (Hello Time + 1 second)
Port Priority
probability the port will be chosen as the Root Port.
– A Port Priority can be from 0 to 255. The lower the number, the greater the

Illustration of STA
A simple illustration of three Bridges (or the Switch) connected in a loop is depicted in Figure 5-
1. In this example, you can anticipate some major network problems if the STA assistance is not
applied. For instance, if Bridge 1 broadcasts a packet to Bridge 2, Bridge 2 will broadcast it to
Bridge 3, and Bridge 3 will broadcast it to Bridge 1 and so on. The broadcast packet will be
passed indefinitely in a loop, causing a serious network failure.
To alleviate network loop problems, STA can be applied as shown in Figure 5-2. In this
example, STA breaks the loop by blocking the connection between Bridge 1 and 2. The decision
to block a particular connection is based on the STA calculation of the most current Bridge and
Port settings. Now, if Bridge 1 broadcasts a packet to Bridge 3, then Bridge 3 will broadcast it to
Bridge 2 and the broadcast will end there.
STA setup can be somewhat complex. Therefore, you are advised to keep the default factory
settings and STA will automatically assign root bridges/ports and block loop connections.
However, if you need to customize the STA parameters, refer to Table 5-1.

Port Trunking
Port Trunking is used to combine a number of ports together to make a single high-bandwidth
data pipeline. The participating parts are called members of a trunk group, with one port
designated as the anchor of the group. Since all members of the trunk group must be configured
to operate in the same manner, all settings changes made to the anchor port are applied to all
members of the trunk group. Thus, when configuring the ports in a trunk group, you only need to
configure the anchor port.
The Switch supports up to 16 trunk groups. Each module on the switch supports up to two trunk
groups except gigabit modules, which support a single trunk group. The Switch treats all ports in
a trunk group as a single port. As such, trunk ports will not be blocked by Spanning Tree.
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. A trunk connection can be made with any other switch that maintains host-to-host data
streams over a single trunk port. Switches that use a load-balancing scheme that sends the
packets of a host-to-host data stream over multiple trunk ports cannot have a trunk connection
with the Switch.
VLAN Structure
VLANs can be defined based on port and IP or IPX protocols and subnets, or various protocols
such as DECnet, NetBios, and AppleTalk. The device can simultaneously support several
VLANs for each protocol.
27
Page 37
Modular L3 Ethernet Switch User’s Guide
The device VLANs are defined as groups of physical interfaces or ports that share the same
network protocols. Once a VLAN is defined, bridging is performed within the VLAN.
For example, if a DECnet VLAN is defined on ports 2 and 3, all DEC traffic between these ports
are bridged.
For IP and IPX VLANs, usually every VLAN is one IP subnet or IPX network. Bridging is
performed between interfaces that belong to the same VLAN. Routing can be activated between
the VLANs.
The following VLAN types can be created:
• IP.
• IPX (four encapsulation types).
• DECnet.
DEC LAT.
•
• XNS.
• SNA.
• AppleTalk.
NetBios.
•
• Other (a super-VLAN that includes all protocols for which VLANs have not been
defined, except IP and IPX), and "User-defined" (for defining an unlisted protocol
or a subnet).
Ports groups associated with a VLAN are user-assigned. For IP protocol VLANs, the AutoConfig
feature can be invoked to cause the device to automatically detect the port configurations.
VLAN Features
The following sections describe the features that are provided with the use of VLANs. This
section includes:
• Bridging Between Network LANs.
• VLAN AutoConfig.
• Scalability.
Bridging Between Network LANs
VLANs effectively performs bridging for non-routable protocols (non-router IP or IPX
networks), such as DECnet, DEClat, AppleTalk, and others.
VLAN AutoConfig
IP VLANs can be location independent. When moving stations to other ports that are not
members of the original VLAN, configuration changes are necessary to inform the router that the
VLAN has been extended to the new destination port. For example, a laptop or PC can be
connected to any network port, even across a WAN connection, and remain a member of the
same VLAN.
With VLAN AutoConfig enabled, changing the system in real-time is automatically detected.
When a change is detected and signaled, the VLAN configuration must be entered into the
system to activate it. The AutoDiscover feature controls the VLAN change detection procedure.
Scalability
Device units can grow with your network, providing all routing services wherever needed. The
following figure illustrates some various connection configuration options.

Broadcast Storms
Broadcast storms are a common problem on today’s networks. Basically, they consist of
broadcast packets that flood and/or are looped on a network causing noticeable performance
degradation and, in extreme cases, network failure. Broadcast storms can be caused by network
loops, malfunctioning NICs, bad cable connections, and applications or protocols that generate
broadcast traffic, among others.
In effect, broadcast storms can originate from any number of sources, and once they are started,
they can be self-perpetuating, and can even multiply the number of broadcast packets on the
network over time. In the best case, network utilization will be high and bandwidth limited until
the hop counts for all broadcast packets have expired, whereupon the packets will be discarded
and the network will return to normal. In the worst case, they will multiply, eventually using up
all the network bandwidth (although network applications will usually crash long before this
happens), and cause a network meltdown.
Broadcast storms have long been a concern for network administrators with routers traditionally
being used to prevent their occurrence, and if that failed, to at least limit their scope. However,
with the advent of VLANs, switches are now able to limit broadcast domains better and cheaper
than routers. Also, many switches, including the DES-6300 series, have broadcast sensors and
filters built into each port to further control broadcast storms.
Segmenting Broadcast Domains
VLANs can be used to segment broadcast domains. They do this by forwarding packets only to
ports in the same VLAN. Thus, broadcast packets will only be forwarded to ports that are
members of the same VLAN. Other parts of the network are effectively shielded. As a result, the
29
Page 39
Modular L3 Ethernet Switch User’s Guide
smaller the broadcast domain, the less effect a broadcast storm will have. Because VLANs are
implemented at each switch port, they can be quite effective in limiting the scope of broadcast
storms.
Eliminating Broadcast Storms
SNMP agents can be programmed to monitor the number of broadcast packets on switch ports
and act on the data. When the number of broadcast packets on a given port rise past an assigned
threshold, an action can be triggered. When enabled, the usual action is to block the port to
broadcast frames, which discards all broadcast frames arriving at the port from the attached
segment. Not only does this isolate the broadcast domain, but it actually starts removing
broadcast packets from the affected segment. When the number of broadcast packets falls to an
acceptable level (below a falling threshold), the SNMP agent can remove the blocking condition,
returning the port to its normal operational state.
In the DES-6300 switch, the default rising threshold is met when more than 500 broadcast
packets per second are being detected on a specified port. Once the rising threshold is surpassed
for a duration of more than 5 seconds, it will trigger the broadcast storm rising action configured
by the user. The default falling threshold is met if there are less than 250 broadcast packets per
second. It is triggered once the duration is at least 30 seconds. The actions can easily be defined
by using a normal SNMP management program or through the console interface.

CONFIGURING THE SWITCH
This section will help configure the Switch user by describing the ConfigMaster program.
ConfigMaster is an intricate SNMP-based network management system that operates as an applet
and as an application. ConfigMaster configures, monitors, and troubleshoots networking devices
both locally at the management console, or remotely using a standard Web browser.
ConfigMaster provides real-time graphs from a wide selection of MIB variables that help
monitor device performance.
ConfigMaster is accessed through a Graphic User Interface (GUI) that displays the actual device
front panel. The panel indicators, such as the LEDs, are mirrored to the front panel display and
are viewed by the network manager.
Figure 6- 1. ConfigMaster Main Screen
32
Page 42
Modular L3 Ethernet Switch User’s Guide
The main window displayed above is used for managing ConfigMaster. It also contains general
information about other ConfigMaster windows and buttons, and describes how to add optional
features to devices.
Installation
This section contains the system requirements and installation instructions for the ConfigMaster,
and includes the following topics:
General System Requirements - Describes the general system requirements for
hardware, software and web based installations.
Installing ConfigMaster - Describes the procedure for installing ConfigMaster.
General System Requirements
Hardware Requirements
The hardware requirements are as follows:
Pentium-Based Machine.
Windows NT 4.0, Windows 95 or Windows 98.
32Mb RAM (64Mb RAM or More Is Recommended).
50 Mb Hard Disk Space.
CD-ROM Drive.
800 x 600 (Minimum Recommended) Screen Resolution.
Software Requirements
The software requirements are as follows:
Microsoft Internet Explorer Version 4.01 or Above.
OR
Netscape Communicator Version 4.5 or Above.
Java Virtual Machine supporting Java version 1.1.4 and Above.
In addition, ConfigMaster runs with:
Sun JVM (JRE).
Microsoft JVM (Wjview).
The DES-6300 has been verified to run with Microsoft’s JVM (Wjview) and Sun’s JVM (jREw).
In case of JRE, we recommend not to use version 1.1.7A because of a known bug. If you decide
to use SUN’s JVM, it is included on the CD-ROM- “Util\Tools\jre117Bi-
win32.exe
If you don’t have a JVM, you can download one of the following:
Sun’s JVM (JRE) –
Microsoft JVM (Jview) (comes with Microsoft Internet Explorer version 4.01 or above) –
http://www.microsoft.com/windows/ie/download
”.
http://java.sun.com/products/jdk/1.1/jre/index.html

description of the Windows 2000 Windows File Protection (WFP) feature can be found in
Microsoft Knowledge Base (KB) article number Q222193.
The Microsoft VM is included with the Windows 2000
Web-Based Installations Requirements
In addition to the hardware and software listed above, a ConfigMaster Web-based installation
requires a web server. Compatible web servers are as follows:
Microsoft IIS Web server version 3.0 and Above.
Netscape Enterprise Web server version 3.0 and Above.
Netscape Fast Track Web Server.
Microsoft Personal Web Server (for a single client only).
Embedded Web Server (EWS)
The DES-6300 offers an embedded Web-based (HTML) interface allowing users to manage the
Switch from anywhere on the network through a standard browser, such as Opera, Netscape
Navigator/Communicator, or Microsoft Internet Explorer. The Web browser acts as a universal
access tool and can communicate directly with the Switch using the HTTP protocol. Your
browser window may vary with the screen shots (pictures) in this guide.
The Web-based management module and the Console program (and Telnet) are different ways to
access the same internal switching software and configure it. Thus, all settings encountered in
Web-based management are the same as those found in the console program.
Getting Started
The first step in getting started in using Web-based management for your Switch is to secure a
browser. A Web browser is a program that allows a person to read hypertext, for example,
Opera, Netscape Navigator, or Microsoft Internet Explorer. Follow the installation instructions
for the browser.
The second and last step is to configure the IP interface of the Switch. This should be done
manually through a console (see the Configure IP Address section in the “Using The Console
Interface” chapter).
You are now ready to begin managing your switch by simply running the browser installed on
your computer and pointing it to the IP address you have defined for the device. The URL in the
address bar should read something like: http://123.123.123.123, where the numbers 123
represent the IP address of the switch. Please note that the proxy fro this session should be turned
off.
After initially entering the IP address into the URL of the browser, the following screen may
appear:

Introduction To VLANs
VLANs are logical subgroups with a Local Area Network (LAN) created via software rather than
defining a hardware solution. VLANs combine user stations and network devices into a single
unit regardless of the physical LAN segment to which they are attached. VLANs allow network
traffic to flow more efficiently within subgroups. VLANs managed through software reduce the
amount of time network changes, additions, and moves are implemented.
VLANs have no minimum number of ports, and can be created per unit, per device, per stack, or
any other logical connection combination, as VLANs are software based and not defined by
physical attributes.
menu. This section contains the following topics:
58
Page 68
Modular L3 Ethernet Switch User’s Guide
VLANs function at a layer 2. Since VLANs isolate traffic within the VLAN, a layer 3 router
working a protocol level is needed to allows traffic flow between VLANs. Layer 3 routers
identify segments and coordinate with VLANs. VLANs are broadcast and multicast domain.
Broadcast and multicast traffic is transmitted only in the VLAN in which the traffic is generated.
The default VLANs are:
IP VLAN.
IPX Raw VLAN.
IPX ET (ETH II) VLAN.
IPX LLC VLAN.
IPX SNAP VLAN.
Note:
IP and IPX VLANs are automatically assigned a MAC address.
SNA, AppleTalk, NetBios.
Other VLANs – The "Other" VLAN is a "super-VLAN" that includes all
protocols for which VLANs have not been defined. However, super-VLAN does
not include IP or IPX. "Other" can be used to quickly configure the device as a full
bridge.
The VLAN menu has the following menu options:
VLAN Parameters
VLAN Tables Per Port
or
VLAN Table Per Port and Protocol.
ConfigMaster supports and automatically recognizes if the device is running VLAN per port or
VLAN per port and protocol.

Configure GVRP and Trunking
Generic Attribute Registration Protocol (GARP) protocol is a general-purpose protocol that
registers any network connectivity or membership-style information. GARP defines a set of
devices interested in a given network attribute, such as VLAN or multicast address.
GARP VLAN Registration Protocol (GVRP) protocol is specifically provided for automatic
distribution of VLAN membership information among VLAN-aware bridges. GVRP allows
VLAN-aware bridges to automatically learn VLANs to bridge ports mapping, without having to
individually configure each bridge, and to register VLAN membership.
To minimize the memory requirements when running the GVRP protocol, two proprietary tuning
variables have been added to the standard variables:
Maximum number of GVRP VLANs – Displays the number of GVRP VLANs
allowed to participate in GVRP operation.
Maximum number of GVRP VLANs after Reset – Sets another value of GVRP
VLANs. Maximum number of GVRP VLANs after Reset is used for tuning. This
value becomes valid after reset only.
The maximum number of GVRP VLANs includes all the VLANs participating in GVRP
operation regardless if they are static or dynamic.
The following should be considered when specifying the maximum number of VLANs
participating in GVRP by setting the Maximum number of GVRP VLANs after Reset value:
The default maximum number of GVRP VLANs is equal to 0 because of the
memory restrictions.
The maximum number of VLANs (managed through Max VLANs MIB variable)
limits the maximum number of GVRP VLANs.
To ensure the correct operation of the GVRP protocol, users are advised to set the
maximum number of GVRP VLANs equal to a value that significantly exceeds the
sum of:
The number of all static VLANs both currently configured and expected
•
to be configured.
• The number of all dynamic VLANs participating in GVRP both
currently configured (initial number of dynamic GVRP VLANs is 0) and
expected to be configured.
Increasing the value of maximum number of GVRP VLANs to value beyond the sums, allows
users to run GVRP, and not reset the device to receive a larger amount of GVRP VLANs. For
example, if 3 VLANs exist and another two VLANs are expected to be configured as a result of
VLAN static or dynamic registration, set the maximum number of GVRP VLANs after reset to
10.
Note: To enable GVRP, ensure that the amount of maximum amount of VLANs is less than
4000. For more information, see the Device Tuning section later in this manual.
To configure the GVRP feature:
1. Enable GVRP on a device.
85
Page 95
Modular L3 Ethernet Switch User’s Guide
2. Enable GVRP per port to participate in GVRP.
3. Specify the maximum number of GVRP VLANs after reset.
4. Reset the device to receive the new maximum number of GVRP VLANs set.
To increase the number of Maximum GVRP VLANs and to reconfigure the GVRP protocol:
1. Specify a new value of the maximum number of GVRP VLANs after reset.
2. Reset the device.
3. Check that the new value is displayed in the Max GVRP VLANs field.

number of GVRP VLANs after Reset fields, see the Device Tuning section later in this manual.
Consideration Concerning STP And GVRP Operation
The circulation of GARP/GVRP registration information follows through the Bridged LANs
active topology and it is assumed that the STP protocol is established and maintained.
Note: When operating in the STP per device mode with the Must belong to VLAN parameter set
to True, STP reacts to GVRP enabled on a port as if a VLAN was created on this port
GARP Timers Control
The GARP Port Timers Control Window contains information about timers for every bridged
port.
To display the GARP Timers Control window:
Select > Device > GARP > GARP Timers Control. The GARP Port Timers Control window
displays.

The
GARP Port Timers Control Window
contains the following fields:
Port—Indicates the port number for which GVRP is enabled.
Join Time—Indicates the time in milliseconds that PDUs are transmitted.
Leave Time—Indicates the time lapse in milliseconds that the device waits
before leaving its GARP state. The Leave Time is activated by a Leave All Time
message sent/received, and cancelled by the Join message received.
Leave All Time—Used to confirm the port within the VLAN. The time in
milliseconds between messages sent.

GVRP Timers Control
The GVRP Timers Control window contains information about timers for every bridged port.
Note: When modifying the default timer values, the Leave value must be greater than three
times the Join value and the Leave All value must be greater than the Leave value:
Leave Time >= 3 x Join Time
Leave All Time > Leave Time
