Connecting the DES-3224 to the

Network

This chapter covers the following:

•

Cable Specifications

•

Ports

•

Connecting the DES-3224 to another DES-3224

•

Connecting the DES-3224 to other switches and hubs

This section deals with making cables and connecting the DES-3224 to other devices. It is extremely important that cables have the correct pin arrangement and that the proper cables be used when connecting to servers, switches, hubs, workstations and other devices.

Cable Specifications

The type of cable you use depends on the speed of your network. A network running at 10

Mbps can use lower grade cable than a network running at 100 Mbps., Table 1: Cable

Length, indicates cable requirements for Ethernet and Fast Ethernet.

Table 1: Cable Length

Ethernet Type

10BASE-T

100BASE-TX

Cable Requirements Maximum Length

Category 3,4, or 5 UTP or STP 328 ft (100 M)

Category 5 UTP or STP 328 ft (100 M)

Do not use telephone cable. Telephone cable does not support Ethernet or Fast Ethernet.

Use the following guidelines when handling cables:

•

Do not stretch or bend cables.

•

Do not put cables near sources of electromagnetic interference.

•

Do not create trip hazards by laying cables in aisles and walkways.

•

Secure cables to the floor when routing in aisles or walkways.

In order for Ethernet or Fast Ethernet to work the wires must be arranged correctly inside the

RJ-45 connector when you make cables. The most common problem on Ethernet or Fast

Ethernet networks is the cable. If you migrate from Ethernet to Fast Ethernet, make sure the cables are pinned out properly.

There are two types of cables: straight through and crossover. Category 3, 4, or 5 UTP/STP cable has eight wires inside the sheath. The wires form four pairs. Straight through cable has the same pin out, inside the RJ-45 connector, at both ends. Crossover cable has a different pin arrangement at each end. Fast Ethernet does not tolerate incorrect pin arrangements. You

Ports

There are three types of ports on the DES-3224: MDI-II Uplink, MDI-X and RS-232. The difference between the MDI-II Uplink port and the MDI-X ports is the internal pin arrangement.

MDI-II Port

An MDI-II port is a straight through port. The pin arrangement is the same as the pin arrangement of a straight through cable.

MDI-X Port

MDI-X ports are crossover ports. The pin arrangement is the same as the arrangement in a crossover cable. The advantage of an MDI-X port is that you can connect a device with an

MDI-II port without using a crossover cable. Just make a straight cable, plug it into the

MDI-II port and plug the other end into another device.

Table 3: Cable Connections, displays the proper cable to use when connecting to various devices.

The steps for connecting the DES-3224 to 10 Mbps devices or 100 Mbps devices are the same. All the ports will auto negotiate the proper speed and duplex mode. The DES-3224 has two rows of 12 MDI-X ports.

Follow these steps to connect cables to the DES-3224:

1. Check for the appropriate cable configuration for each device.

2. Plug one end of the cable into the MDI-II Uplink port, if appropriate, or any of the

MDI-X ports.

3. Plug the other end into the appropriate port on the other device.

4. Verify that the LED indicates connection at the proper speed and duplex mode.

RS-232 Port

The RS-232 Port is located at the rear of the DES-3224. The RS-232 port is a female port that is used for serial communication. By connecting the DES-3224 and a PC you can configure the DES-3224 and check its status and configurations even when the network is down. Use the RS-232 cable provided to connect the DES-3224 and a PC.


10


DES-3224 to DES-3224 Connection

There are two ways to connect DES-3224s together: MDI-II uplink port or MDI-X ports. See

Table 3: Cable Connections for the proper connections to use with each type of port. The

DES-3224 is also compatible with the DES-5016 and DES-5024. Port Trunking can be configured on the device if more than one port is connected between two DES-3224s or if more than one ports is connected between a DES-3224, DES-5016 and DES-5024. Port trunking increases the efficiency of the DES-3224 by increasing the bandwidth. See the section on Port Trunking in Chapter 5 for instructions on how to configure Trunked ports.

Connecting the DES-3224 to the DES-5024 and

Hubs

You can connect the DES-3224 to other switches and hubs on the network. The DES-3224 and the DES-5024 are compatible products that can be connected easily. If you create multiple connections between devices, create Trunked ports for more efficiency. See the section on Port Trunking for more details. Determine the type of port you will be connecting to and refer to Table 3: Cable Connections for the proper cable connections to use.

Managing the DES-3224

This chapter shows the menus used to manage the DES-3224.

Three types of management are available on the DES-3224:

•

Local Console Management (out-of-band)

•

Telnet Management (in-band)

•

D-View/ SNMP Management

The DES-3224 can be managed in-band or out-of-band. In-band management refers to managing the DES-3224 through the MDI-II uplink port or any of the MDI-X ports. Out-ofband management means going through the RS-232 port.

The interface and options are the same with Local Console and Telnet Management. The difference is the type of connection and the port that is used to manage the DES-3224.

D-View is a proprietary SNMP management program. D-View is provided with the DES-

3224. The DES-3224 supports other SNMP management applications and uses standard

MIB. Refer to appropriate documentation for installing and using other SNMP application programs. The look and feel of D-View is different from other management types. Refer to other documentation if you are using other vendors’ SNMP applications.

All instructions given in this chapter assume that you are logged into the DES-3224 and are at the appropriate panel for carrying them out.

Local Console Management

Local Console Management is always done through the RS-232 Serial port and requires a direct connection between the DES-3224 and a PC. This type of management is very useful when the network is down and the DES-3224 cannot be reached by any other means.

Use Local Console Management to log into the DES-3224 for the first time. You do not need to know the IP address to log into the DES-3224 using Local Console Management. You can change all the settings and configure the DES-3224, set the IP address and perform other management functions.

Follow these steps to begin a management session using Local Console Management:

1. Attach the male end of the RS-232 serial cable provided with the DES-3224 to the RS-

232 port located at the rear of the DES-3224.

2. Attach the other end to the serial port of a PC or workstation.

3. Run a terminal emulation program using the following settings:

•

Emulation: VT-100/ANSI compatible

•

BPS: 19 200

•

Data bits: 8

Default Password: D-Link

5. Press Enter to reach the Main menu.

Telnet

You can manage the DES-3224 via Telnet session. However, first you must assign a unique

IP address to the DES-3224. Use Local Console Management to log into the DES-3224 for the first time so that you can assign an IP address. Once you have assigned an IP address to the DES-3224, you can use the management method of your choice.

Telnet management can be done through the MDI-II Uplink port of the DES-3224 or any of the MDI-X ports on either switch.

Follow these steps to manage the DES-3224 through a Telnet session:

1. Assign an IP address to the DES-3224.

2. Run Telnet.

3. Log into the DES-3224.

27


System Rate Control

The System Rate Control panel, displayed in Figure 14, allows you to set the packet forwarding rate on the DES-3224. There are two options: Store & Forward and Cut-Through.

Figure 14: System Rate Control

The DES-3224 can be set for Store and Forward or Cut-Through. This is a global setting that affects all the ports except the RS-232 port.

Store and Forward means that when the DES-3224 receives an incoming packet it “stores” the packet until the entire data packet has been received before it “forwards” the packet to a destination.

In Cut-Through mode the DES-3224 begins sending out the packet as soon as it receives the first 128 bytes of data. The first 128 bytes contain the destination of the packet.

Advantages of Store and Forward

Store and Forward only sends out valid data packets. Bad packets created by collisions on the network or damaged packets are filtered out.

Always use Store and Forward when some devices on the network run at 10 Mbps and others run at 100 Mbps.

Disadvantages of Store and Forward

Store and Forward requires more time because it receives the whole packet before sending it out. Every byte buffered is an additional eight microseconds of delay. For example, 1500


28

10/100 Auto Negotiation Switch User’s Guide byte packets are delayed by 1200 microseconds in a Store and Forward device versus 60 microseconds in a Cut-Through device.

Store and Forward requires more memory because the DES-3224 must store the packet before sending it out.

Advantages of Cut-Through

Cut-Through is faster because the packet is sent as soon as the first 128 bytes are received.

Cut-Through requires less memory since the DES-3224 only reads the address but does not store the entire message.

Disadvantages of Cut-Through

Bad packets are perpetuated, taking up bandwidth.

The benefits diminish in high traffic networks.

Cut-Through can not be used on networks that use both Ethernet and Fast Ethernet. The network must use one or the other.

Follow these steps to change the default setting from Store and Forward to Cut-Through:

1. Toggle the space bar to change the setting.

2. Select Save and press Enter.

3224. All three panels are dealt with together. The only difference between the three panels is the port number that they deal with. The options and settings are the same for each. Select the group of ports that you want to configure and then go to the appropriate panel.

Follow these steps to select a panel:

1. Decide which group of ports you would like to work with.

2. Select the group on the Console Program panel.

3. Press Enter to go to the appropriate panel.

Switch Port Configuration Menu

The Switch Port Configuration menu, displayed in Figure 23, enables you to change the configurations of individual ports.

Figure 23: Switch Port Configuration menu

State

All ports have two states: enabled or disabled. Enabled ports transmit and receive data packets. Disabled ports can not transmit or receive packets. You can disable a port but you will not be able to use a disabled port.


38


Physical

Refers to the physical state of the port. If you manually change the state of a port it will remain in that state until you change it. It will not auto negotiate speed and duplex mode. All ports can be in the following physical states:

•

Auto

•

100Tx/Half

•

100Tx/Full

•

10Tx/Half

•

10Tx/Full

Ports in the Auto state automatically negotiate speed and duplex mode. This is the default setting.

Ports set in the 100Tx/Half physical state are set to work at 100 Mbps half duplex.

Ports set in the 100Tx/Full state are set to work at 100 Mbps full duplex.

Ports set in the 10Tx/Half state are set to work at 10 Mbps half duplex.

Ports set in the 10Tx/Full state are set to work at 10 Mbps full duplex.

Port State

All ports have four states: blocking, listening, learning and forwarding. Blocking means that nothing is coming through the port. If the Spanning Tree Algorithm detects a loop it will change the state of the port where the loop is detected to the Blocking State. You can disable the Spanning Tree Algorithm. Forwarding means the port is forwarding data packets to their destination. Listening means that the port is listening for data packets. Learning means the port is learning the MAC address for data packets. This setting cannot be manually changed.

Priority

The port priority can be set from zero to 255. Zero is the highest port priority. The port assigned a zero will be the root port. The default setting will work in most situations.

Follow these steps to change the port state:

1. Select the State setting of the appropriate port.

2. Toggle the space bar to change the current setting.


Follow these steps to change a port’s physical state:

1. Select the physical setting of the appropriate port.

2. Toggle the space bar until you find the appropriate setting.


Follow these steps to change the port Priority:

1. Select the Priority of the appropriate port.


39


2. Enter a new value between zero and 255.


Spanning Tree Configuration

The Spanning Tree Configuration panel is used to configure the Spanning Tree Algorithm.

The Spanning Tree Algorithm (STA) in the DES-3224 allows you to create alternative paths

(using multiple switches or bridges) in your network. These backup paths are idle until the

DES-3224 determines that a problem has developed in the primary path. If the primary path breaks down STA will activate the backup path. STA is very complicated and you should understand it well before changing the default settings.

STA Operation Levels

STA operates on the bridge level and the port level. On the bridge level, STA calculates the

Bridge Identifier for each DES-3224 then sets the Root Bridge and the Designated Bridges.

On the port level, STA sets the Root Port and Designated Ports.

Spanning Tree Configuration Menu

The Spanning Tree Configuration menu, displayed in Figure 24, allows you to enable or disable STA, set bridge priority and other configurations.

Figure 24: Spanning Tree Configuration menu


40


Spanning Tree Algorithm

Spanning Tree Algorithm can be enabled or disabled. Use Spanning Tree to prevent network loops.

Bridge Priority

The Bridge Priority can be from 0 to 65535. Zero is the highest Bridge Priority. The higher the Bridge Priority the greater the chance that the DES-3224 will be selected as the Root

Bridge. The DES-3224 with the highest Bridge Priority is the Root Bridge.

Root Cost

The Root Cost is the number of times a packet is regenerated before reaching its destination.

A source sends a packet to the first device (switch or hub) on the network. When the packet reaches the next hub or switch and it is sent out again, the Path Cost becomes two. Each switch and active hub regenerates the packet. To determine the Root Path Cost, count the number of times the packet is regenerated.

The switch with the lowest Path Cost is the Root Bridge. Make the Root Bridge the best switch on the network.

Hello Time

Is the interval between two transmissions of packets sent by the Root Bridge to tell all other switches that it is the Root Bridge. The Hello Time can be set manually, with a range in seconds from 1 to 10. If the Hello Time is set for the switch and the switch is not the Root

Bridge then the Hello Time will not take effect until the switch becomes the Root Bridge.

Forward Delay Time

This is the time any port on the DES-3224 spends in the listening state while moving from the listening state to the forwarding state. It can be set from 4 to 30 seconds.

Use the following formula when setting the Hello Time and the Forward Delay Time:

2 x (Forward Delay minus 1 second) > Max Age

2 x (Hello Time plus 1 second) < Max Age

Max Age Time

Is the time a non-root bridge waits for a packet to be sent. At the end of the Max Age, if a packet has not been received from the Root Bridge, the DES-3224 will start sending its own packets and request permission to become the Root Bridge. If it turns out that the DES-3224 has the lowest Bridge Identifier it will become the Root Bridge.

The switch with the lowest Bridge Identifier is the Root Bridge. It is best to make the Root

Bridge the best switch on the network to ensure the best network performance and reliability.


41


Root Bridge

Specifies the MAC address of the Root Bridge. The DES-3224 may or may not be the root bridge. The DES-3224 is the default root bridge.

Root Port

Specifies the preferred path to the Root Bridge. Only one path per bridge can exist. The default setting is none.

SNMP Management Configuration

The SNMP Management Configuration panel is used to configure the DES-3224 for SNMP management. Leave the default values in place if you are not managing your network through SNMP.

The DES-3224 uses the standard MIB-II Management Information Base module. The MIB values can be retrieved from any SNMP based network manager. The DES-3224 supports its own proprietary enterprise as an extended MIB. The MIB can be retrieved by specifying their

Object-Identity (OID). MIB values can be either read-only or read-write.

Read-only MIB variables can be constants that are programmed into the DES-3224 or variables that change while the DES-3224 is running. For example, the number and type of ports on the DES-3224 is a read-only constant. The number and type of ports is fixed.

Statistics, such as the number of errors that have occurred, are read-only variables.

Read-write MIBs are usually related to user customized configurations. Examples of these are the DES-3224’s IP address, STA parameters and port status.

If you use third party vendors’ SNMP software to manage the DES-3224, a diskette listing the DES-3224’s proprietary enterprise MIB can be obtained by request. If your software provided functions to browse or modify MIB, you can get the MIB values and change them

(if the MIB’s attributes permit the write option). This process can be difficult. You must know the MIB OIDs and retrieve them one by one.

SNMP Management Configuration Menu

The SNMP Management Configuration menu, displayed in Figure 25, enables you to configure the DES-3224 for SNMP management.


43


Figure 25: SNMP Management Configuration menu

SNMP Manager Setting

The fields under this setting are used to configure the DES-3224 for SNMP Management.

You must configure these fields in order to manage the DES-3224 through SNMP.

SNMP Community String

The SNMP Community String field allows you to name the SNMP Communities. The names public and private are only default names. For security you should change these names to help prevent unauthorized access to the DES-3224.

You can name the SNMP communities anything you like. You can enter up to 32 characters in each of the four fields. You can create up to four SNMP Communities.

Access Right

Enables you to set the rights that members of the SNMP Communities have. Read Only access rights mean that members in the community can view the information on the DES-

3224 but they can not make changes to the configurations. Read/ Write access rights allow the members of the community to make any changes they desire.

Status

Can be Valid or Invalid. Only communities with Valid status can access the DES-3224.

Communities with Invalid status cannot access the DES-3224.


44


SNMP Trap Manager Setting

Enables you to enter the IP addresses of Trap Managers. Traps are messages the DES-3224 sends out to inform trap managers of events on the network. The DES-3224 generates traps and sends them to the network manager. Trap managers are special network users who are given certain rights and access to oversee and maintain the network. This feature is available only in D-View or by using other SNMP management software.

You can specify which network managers may receive traps from the DES-3224 by creating a list of IP Addresses of the authorized network managers.

Trap managers can receive the following trap types:

•

Cold Start

•

Authentication Failure

•

Link Change Event

Cold Start

Signifies that the DES-3224 has been powered up. Software settings are reconfigured and hardware systems are rebooted. A cold start is different from a factory reset.

Authentication Failure

Signifies that an addressee (or manager/ user) on the DES-3224 is not a valid user of the

DES-3224 and may have entered an incorrect community name.

Link Change Event

Signifies that the link of a port has changed from link up to link down or vice versa.

IP Address

This field is used to enter the IP Addresses of Trap Managers.

SNMP Community String

Enter the Community String of the Trap Mangers in this field.

Status

The DES-3224 will not send out traps unless the status is Valid.

Follow these steps to enter the SNMP Community String:

1. Enter the name of the SNMP Community.

2. Select the Access Right field and toggle the space bar to select Read Only or Read/

Write.

3. Select the Status field and toggle the space bar to select Valid or Invalid.

A Virtual Local Area Network (VLAN) is a logical subgroup within a LAN that is created with software rather than physical connections. The purpose of a VLAN is to prevent broadcast storms and ease congestion on your network.

Each VLAN created is a broadcast domain. A broadcast is a packet that is sent to all nodes on the network. A broadcast domain is a domain in which every node in the domain receives the broadcast packet. The advantage of creating VLANs is that they permit you to group

LAN segments together in order to get the most out of your network.

VLANs become more important as the network grows and traffic increases. VLANs are usually used on high traffic networks. You should consider a VLAN on a smaller network if a department or workgroup routinely does tasks that take up a lot of bandwidth and they are not already on their own LAN segment.

VLANs can be used to subdivide the network. The DES-3224 supports port based VLAN.

Port based VLAN means that the VLAN is grouped by port. If a VLAN is created using three ports, then those ports become a separate broadcast domain.

By using VLANs, members of a particular department or workgroup can be partitioned from the rest of the network. For example, the marketing department can be on one VLAN and the accounting department can be on another. If a workstation in marketing sends a broadcast packet to another workstation in marketing the packet will remain in the marketing VLAN.

VLAN Port Management Menu

The VLAN Port Management menu, displayed in Figure 26, enables you to create, delete and modify VLANs on the DES-3224.

Create/ View VLAN

The Create/View VLAN menu, displayed in Figure 27, is used to create a new VLAN. The default value is that all ports belong to one VLAN. You can create up to eight separate

VLANs. Ports can belong to two VLANs at the same time. Each VLAN is a broadcast domain. If you have created a trunking group, you must include the entire trunk group in the

VLAN.

Troubleshooting

This troubleshooting section is intended to help you solve the most common problems on the

DES-3224.

Many problems on the DES-3224 are indicated by the Utilization LED during the powering on process. All LEDs are explained in detail in Chapter 4, LEDs. Error codes are displayed on the Utilization LED. Table 8, System Error LED Indicators, displays the meaning of the error code. If you are having a problem that is not discussed here, contact technical support.

Problem Solution

POST Errors

Cables

Port States

The DES-3224 performs a Power On Self Test (POST) every time it is powered on. If you are connected to the

DES-3224 through Local Console Management during the POST you can see the results displayed on your monitor. The login screen appears after the DES-3224 has completed the POST.

The POST checks all of the hardware components on the DES-3224.

Faulty cables are the most common source of problems on Ethernet and Fast Ethernet networks. Check the cables first if you are having any problems connecting to a device.

Ethernet is more fault tolerant than Fast Ethernet. If you are moving from Ethernet to Fast Ethernet, make sure the cables are pinned out correctly. See Chapter 3,

Connecting the DES-3224 to the Network, Cable

Specifications, for a diagram showing the proper pin arrangement for Ethernet and Fast Ethernet.

All ports on the DES-3224 have two modes: auto negotiation mode and forced mode. Ports in auto negotiation mode auto negotiate the proper speed and duplex mode. Ports in forced mode have been manually set to a particular speed and duplex mode. Check the

LEDs on the DES-3224 and on the Network Interface

Card to verify settings. See Chapter 4, LEDs, for an explanation of all LEDs.

The port settings on the DES-3224 and the port settings on the device you are connecting to must be the same in

order for them to communicate. Check the speed and duplex setting on both the port and device you are connecting to.

Check the power plug and verify that you are getting power from the wall socket. If the DES-3224 is on, the power LED is not working properly. Return DES-3224.

If the DES-3224 is not powering on and power is being received though the wall socket, the power supply is not working. Return the unit.

Check the power plug and verify that the DES-3224 is receiving adequate power. Log in to the DES-3224 using Local Console Management, see Chapter 5,

Managing the DES-3224, for instructions.

Power the DES-3224 off and then power it on again.

Use the monitor to check the error messages. Return the

DES-3224 to D-Link for service if the problem persists.
