ABOUT THIS GUIDE

Congratulations on your purchase of the DGS-1224T24-Port10/100/1000Mbps Gigabit Ethernet +2-PortMini GBICWeb-SmartSwitch. This device integrates 1000Mbps Gigabit Ethernet, 100Mbps Fast Ethernet and 10Mbps Ethernet network capabilities in a highly flexible package.

Purpose

This guide discusses how to install and use the configuration functions of the DGS-1224TWeb-SmartSwitch.

Terms/Usage

In this guide, the term “Switch” (first letter capitalized) refers to the DGS-1224TWeb-SmartSwitch, and “switch” (first letter lower case) refers to other Ethernet switches. Some technologies refer to terms “switch”, “bridge” and “switching hubs” interchangeably, and both are commonly accepted for Ethernet switches.

1

INTRODUCTION

This chapter describes the features of the DGS-1224Tand provides some background information about Ethernet/Fast Ethernet/Gigabit Ethernet switching technology.

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 100-MbpsFast Ethernet and a hundredfold increase over10-MbpsEthernet. Since it is compatible with all10-Mbpsand100-MbpsEthernet environments, Gigabit Ethernet provides a straightforward upgrade without wasting existing investments in hardware, software, and trained personnel.

The increased speed and extra bandwidth offered by Gigabit Ethernet is essential to helping solve network bottlenecks that frequently develop as more advanced computer users and newer applications continue to demand greater network resources. Upgrading key components, such as backbone connections and servers to Gigabit Ethernet technology can greatly improve network response times as well as significantly speed up the traffic between subnets.

Gigabit Ethernet enables fast optical fiber connections to support video conferencing, complex imaging, and similar data-intensiveapplications. 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.

2

In addition, the phenomenal bandwidth delivered by Gigabit Ethernet is the most cost-effectivemethod 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 unshieldedtwisted-pair(UTP) cabling, outfitting your network with a powerful1000-Mbps-capable backbone/server connection creates a flexible foundation for the next generation of network technology products.

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-speedLAN technologies have been proposed to provide greater bandwidth and improve client/server response times. Among them,100BASE-T(Fast Ethernet) provides anon-disruptive,smooth evolution from the current10BASE-Ttechnology. Thenon-disruptiveand smooth evolution nature, and the dominating potential market base, virtually guaranteescost-effectiveand high performance Fast Ethernet solutions.

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 CSMA/CD Ethernet protocol. Since the 100Mbps Fast Ethernet is compatible with all other 10Mbps Ethernet environments, it provides a straightforward upgrade and utilizes existing investments in hardware, software, and personnel training.

3

Switching Technology

Another approach to pushing beyond the limits of Ethernet technology is the development of switching technology. A switch bridges Ethernet packets at the MAC address level of the Ethernet protocol transmitting among connected Ethernet or Fast Ethernet LAN segments.

Switching is a cost-effectiveway of increasing the total network capacity available to users on a local area network. A switch increases capacity and decreases network loading by dividing a local area network into different segments, which don’t compete with each other for network transmission capacity.

The switch acts as a high-speedselective bridge between the individual segments. The switch, without interfering with any other segments, automatically forwards traffic that needs to go from one segment to another. By doing this the total network capacity is multiplied, while still maintaining the same network cabling and adapter cards.

IEEE 802.1Q VLAN

A Virtual Local Area Network (VLAN) is a group of end-stationsthat are not constrained by their physical location and can communicate as if located on a common broadcast domain, or a LAN. The primary utility of using VLAN is to reduce latency and need for routers, in favor of using faster switching technologies instead. The IEEE 802.1Q specification provides a standard for tagging Ethernet frames with VLAN membership information. The 802.1Q standard is intended to address the problem of how to break large networks into smaller parts

4

so broadcast and multicast traffic use valuable network bandwidth more efficiently. Additional VLAN benefits include:

Security: Security is increased with the reduction of opportunity in eavesdropping on a broadcast network because data will be switched to only those confidential users within the VLAN.

Cost Reduction: VLANs can be used to create multiple broadcast domains, thus eliminating the need of expensive routers.

VID: VLAN ID is an identification of up to 4094 possible VLANs. A VID of 0 is used to identify priority frames. The value 4095 (FFF) is reserved, so the maximum possible VLAN configurations are 4,094.

Web-basedUtility

The DGS-1224TWeb-SmartSwitch has a web browser GUI interface for configuring the Switch through a web browser. To see the list of web browsers theWeb-basedUtility supports, seeSupported web browsers on page 20. A network administrator can manage, control and monitor the Switch from a PC on the local LAN. This section describes how to operate the functions found in theWeb-basedUtility.

Login

Before beginning to configure the Web-SmartSwitch through a web browser over an Ethernet connection, the PC used to manage the Switch must reside on the same the IP network. By default, the Switch automatically obtains an IP address from a DHCP Server. The admin configuring the Switch must check the LAN’s DHCP Server to identify the IP Address assigned to the Switch. The default IP address is 192.168.0.1 if the Switch cannot successfully obtain an IP address from a DHCP Server. If the DHCP assigned IP address of the WebSmart Switch is 192.168.0.1, then the managing PC should use 192.168.0.x (where x is a number between 2 and 254) as its IP address, with a subnet mask also being the same (255.255.255.0 if not assigned by a DHCP Server). To begin, open a supported web browser and enter the IP address of the Switch (ex http://192.168.0.1).

Flow Control: This setting determines if the Switch handles flow control. Set toEnable to avoid data transfer overflows. Default setting for all ports isDisable.

Link Status: ReportingDown indicates the port is disconnected.

Priority: Displays each port’s 802.1P QoS priority level for received data packet handling. Default setting for all ports isMiddle.

NOTE: The priority of Gigabit Fiber ports are by default higher than Copper ports.

System > SNMP Setting

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 or LAN.

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-boardSNMP agent. SNMP defines both the format of the MIB specifications and the protocol used to access this information over the network.

Community Setting: In support of SNMP version 1, theWeb-SmartSwitch accomplishes user authentication by using Community Settings that function as passwords. The remote user SNMP application and the Switch SNMP must use the same community

33

string. SNMP packets from a station that are not authenticated are ignored (dropped).

Figure 26 – System > SNMP Setting

Enabled / Disabled: Default setting isDisabled. ClickEnable, thenApply, to set Community Settings.

The default community strings for the Switch used for SNMP v.1 management access are:

Public: The community withread-onlyprivilege allows authorized management stations to retrieve MIB objects.

Private: The community with read/write privilege allows authorized management stations to retrieve and modify MIB objects.

Trap Setting: Traps are messages that alert network personnel of events that occur on the Switch. Such events can be as serious as a reboot (someone accidentally turned the Switch OFF), or less serious

34

events such as a port status change. The Switch can generate traps and send them to the trap recipient (i.e. network administrator).

Setting up a Trap: SelectEnable, enter a Trap Name (i.e. Trap Name must be selected from a Community Name), add the IP of the device to be monitored, and choose the event(s) to trap. The available trap Events to choose from include: System Device Bootup, Fiber Link Up / Link Down, Fiber Abnormal Receive Error, Fiber Abnormal Transmit Error, Twisted Pair Link Up / Link Down, Twisted Pair Abnormal Receive Error, Twisted Pair Abnormal Transmit Error.

System > Password Access Control

Setting a password is a critical tool for managers to secure the WebSmart Switch. After entering the old password and the new password two times, press Apply for changes to take effect.

Configuration > Jumbo Frame

By default, the Jumbo Frame function is set to Disabled. Enabling this function will allow the Switch to receive packets sizes of up to 10,240 bytes.

Figure 28 – Configuration > Jumbo Frame

Configuration > 802.1Q VLAN

The IEEE 802.1Q VLAN Configuration page provides powerful VID management functions. By default, VID is 01, is named “default”, and includes all 24 ports as “Untagged” (see Figure 29).

Rename: Press to rename the VLAN group.Delete VID: Press to delete the VLAN group.

Add New VID: Press to create a new VID group, assigning ports from 01 to 24 asUntag,Tag, orNot Member. A port can be “Untagged” in only one VID. To save the VID group, pressApply.

Configuration > Trunking

The Trunking function enables the cascading of two or more ports for a combined larger bandwidth. Up to six Trunk groups may be created, each supporting up to 8 ports. Add a Trunking Name and select the ports to be trunked together, and clickApply to activate the selected Trunking groups.

Figure 33 – Configuration > Trunking

NOTE: Each combined trunk port must be connected to devices within the same VLAN group.

Configuration > IGMP Snooping

With Internet Group Management Protocol (IGMP) snooping, the Web-SmartSwitch can make intelligent multicast forwarding decisions by examining the contents of each frame’s Layer 3 IP

39

header. IGMP snooping can help reduce cluttered traffic on the LAN. With IGMP snooping enabled globally, the Web-SmartSwitch will forward IP multicast traffic only to connections that have group members attached.

Figure 34 – Configuration > IGMP Snooping Configuration

By default, IGMP is Disabled. IfEnabled, the IGMP Global Settings will need to be entered:

Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting the Query Interval, the number of IGMP messages can increase or decrease; larger values cause IGMP Queries to be sent less often. Default is 125 seconds.

Max Response Time (10-25 sec): The Max Response Time specifies the maximum allowed time before sending a responding report. Adjusting this setting effects the "leave latency", or the time between the moment the last host leaves a group and when the routing protocol is notified that there are no more members. It also allows adjustments

40

for controlling the frequency of IGMP traffic on a subnet. Default is 10 seconds.

Robustness Variable (1-255sec):The Robustness Variable allows adjustment for the expected packet loss on a subnet. If a subnet is expected to be lossy, the Robustness Variable may be increased. The Robustness Variable can not be set zero, and SHOULD NOT be one. Default is 2 seconds.

Last Member Query Interval (1-25sec):The Last Member Query Interval is the Max Response Time inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of the network. A reduced value results in reduced time to detect the loss of the last member of a group. Default is 1 second.

Host Timeout (130-1225 sec): This is the interval after which a learnt host port entry will be purged. For each host port learnt, a 'PortPurgeTimer' runs for 'HostPortPurgeInterval'. This timer will be restarted whenever a report message from host is received over that port. If no report messages are received for 'HostPortPurgeInterval' time, the learnt host entry will be purged from the multicast group. Default is 260 seconds.

Router Timeout (60-600 sec): This is the interval after which a learnt router port entry will be purged. For each router port learnt, a 'RouterPortPurgeTimer' runs for 'RouterPortPurgeInterval'. This timer will be restarted whenever a router control message is received over that port. If no router control messages are received for 'RouterPortPurgeInterval' time, the learnt router port entry will be purged. Default is 125 seconds.

Leave Timer (0-25 sec): This is the interval after which a Leave message is forwarded on a port. When a leave message from a host for

41

a group is received, a group-specificquery is sent to the port on which the leave message is received. A timer is started with a time interval equal to IgsLeaveProcessInterval. If a report message is received before above timer expires, the Leave message is dropped. Otherwise the Leave message is either forwarded to the port. Default is 1 second.

To enable IGMP snooping for a given VLAN, select Enable under

State then press the Edit button under Static Router Port Setting, then select the ports to be assigned for IGMP snooping for the VLAN, and press Applyfor changes to take effect.

Configuration > 802.1D Spanning Tree

802.1D Spanning Tree Protocol (STP) implementation is designed to prevent network loops that could cause a broadcast storm. When physical links forming a loop provide redundancy, only a single path will be forwarding frames. If the link fails, STP activates a redundant link automatically.

Figure 37 – Configuration > Spanning Tree

By default, Spanning Tree is Disabled. IfEnabled, the Switch will listen for BPDU packets and its accompanying 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. Adraw-backof 802.1D is this absence of immediate feedback from adjacent bridges.

After Enabling STP, setting the STP Global Setting includes the following options:

44

Bridge Priority: This value between 0 and 65535 specifies the priority for forwarding packets: the lower the value, the higher the priority. The default is 32768.

Bridge Max Age: This value may be set to ensure that old information does not endlessly circulate through redundant paths in the network, preventing the effective propagation of the new information. Set by the Root Bridge, this value will aid in determining that the Switch has spanning tree configuration values consistent with other devices on the bridged LAN. If the value ages out and a BPDU has still not been received from the Root Bridge, the Switch will start sending its own BPDU to all other switches for permission to become the Root Bridge. If it turns out that the Switch has the lowest Bridge Identifier, it will become the Root Bridge. A time interval may be chosen between 6 and 40 seconds. The default value is 20.

Bridge Hello Time: The user may set the time interval between transmissions of configuration messages by the root device, thus stating that the Switch is still functioning. The default is 2 seconds.

Bridge Forward Delay: This sets the maximum amount of time that the root device will wait before changing states. The default is 15 seconds.

Root Bridge: Displays the MAC address of the Root Bridge.Root port: Displays the root port.

Root Path Cost: Shows the root path cost.

Path Cost: This defines a metric that indicates the relative cost of forwarding packets to specified port list. The lower the number, the greater the probability the port will be chosen to forward packets. The default value is 19.

45

Path Priority: Select a value between 0 and 255 to specify the priority for a specified port for forwarding packets: the lower the value, the higher the priority. The default is 128.

Configuration > Port Mirroring

Port Mirroring is a method of monitoring network traffic that forwards a copy of each incoming and/or outgoing packet from one port of the Switch to another port where the packet can be studied. This enables network managers to better monitor network performances.

Figure 38 – Configuration > Port Mirroring

Selection options for the Source Ports are as follows:

TX (transmit) mode: Duplicates the data transmitted from the source port and forwards it to the Target Port.

46

RX (receive) mode: Duplicates the data that send to the source and forwards it to the Target Port.

Both (transmit and receive) mode: Duplicate both the data transmitted from and data send to the source port, and forwards all the data to the assigned Target Port.

None: Turns off the mirroring of the port.

QoS > 802.1p Default Priority

This feature displays the status Quality of Service priority levels of each port, and for ports that are Untagged, the priority can be adjusted.

Figure 39 – QoS > 802.1p Default Priority

Security > Safeguard Engine

By default is Enabled,D-Link’sSafeguard Engine is a robust and innovative technology that automatically throttles the impact of packet

47

flooding into the switch's CPU. This function helps protect the WebSmart Switch from being interrupted by malicious viruses or worm attacks.

Figure 40 – Security > Safeguard Engine

Security > Broadcast Storm Control

The Broadcast Storm Control (BSC) feature provides the ability to control the receive rate of broadcasted packets. If Enabled (default is

Disabled), threshold settings of8,000;16,000;32,000;64,000 bytes per second can be assigned. PressApply for the settings to take effect.

48

Figure 41 – Security > Broadcast Storm Control

Security > 802.1X Setting

IEEE-802.1Xprovides a security standard for network access control, predominantly inWi-Fiwireless networks. 802.1X holds a network port disconnected until authentication is completed. Depending on the results, the port is either made available to the user, or the user is denied access to the network. 802.1X uses the Extensible Authentication Protocol (EAP) for passing authentication messages.

49

Figure 42 – QoS > 802.1X Setting

By default, 802.1X is Disabled. To use EAP for security, selectEnabled and set the 802.1XGlobal Settings for the Radius Server and applicable authentication information.

Authentication Port: sets primary port for security monitoring. Default is 1812.

Key: Masked password matching the Radius Server Key.Confirm Key: Enter the Key a second time for confirmation.

TxPeriod: Sets the number of seconds that the switch waits for a response to anEAP-request/identityframe from the client before retransmitting the request. Default is 24 seconds.

ReAuthEnabled: ThisEnables orDisables the periodic ReAuthentication control. When the 802.1X function isEnabled, the ReAuthEnabled function is by default alsoEnabled.

50

QuietPeriod: Sets the number of seconds that the switch remains in the quiet state following a failed authentication exchange with the client. Default 80 seconds

SuppTimeout: Sets theswitch-to-clientretransmission time for theEAP-requestframe. Default is 12 seconds.

ServerTimeout: Sets the amount of time the switch waits for a response from the client before resending the response to the authentication server. Default is 16 seconds.

MaxReq: This parameter specifies the maximum number of times that the switch retransmits an EAP Request packet to the client before it times out the authentication session. Default is 5 times.

ReAuthPeriod: This command affects the behavior of the switch only if periodicre-authenticationis enabled. Default is 3600.

To establish 802.1X port-specificassignments, select theFrom andTo Ports and selectEnable.

51

Security > Mac Address Table > Static MAC

This page provides two distinct features. The top table provides the ability to turn off auto learning Mac address if a port isn't connected to an uplink Switch (i.e. DHCP Server). By default, this feature is OFF (disabled).
