2. Installation

2-1. Starting switch Up

This section will give users a quick start for:

- Hardware and Cable Installation

- Management Station Installation

- Software booting and configuration

2-1-1. Hardware and Cable Installation

At the beginning, please do first:

⇒ Wear a grounding device to avoid the damage from electrostatic discharge ⇒ Be sure that power switch is OFF before you insert the power cord to power

source

• Installing Optional SFP Fiber Transceivers Note: If you have no modules, please skip this section.

• Connecting the SFP Module to the Chassis:

The optional SFP modules are hot swappable, so you can plug or unplug it before or after powering on.

1. Verify that the SFP module is the right model and conforms to the chassis

2. Slide the module along the slot. Also be sure that the module is properly

seated against the slot socket/connector

3. Install the media cable for network connection

4. Repeat the above steps, as needed, for each module to be installed into

slot(s)

Fig. 2-1 Installation of Optional SFP Fiber Transceive

5. Have the power ON after the above procedures are done

• TP Port and Cable Installation

⇒ In the switch, TP port supports MDI/MDI-X auto-crossover, so both types of

cable, straight-through (Cable pin-outs for RJ-45 jack 1, 2, 3, 6 to 1, 2, 3, 6 in 10/100M TP; 1, 2, 3, 4, 5, 6, 7, 8 to 1, 2, 3, 4, 5, 6, 7, 8 in Gigabit TP) and crossed-over (Cable pi n-outs for R J-45 jack 1, 2, 3, 6 to 3, 6, 1, 2) can be used. It means you do not have to tell from them, just plug it.

⇒ Use Cat. 5 grade RJ-45 TP cable to connect to a TP port of the switch and the

other end is connected to a network-aware device such as a workstation or a server.

⇒ Repeat the above steps, as needed, for each RJ-45 port to be connected to a

Gigabit 10/100/1000 TP device.

Now, you can start having the switch in operation.

• Power On

The switch supports 100-240 VAC, 50-60 Hz power supply. The power supply will automatically convert the local AC power source to DC power. It does not matter whether any connection plugged into the switch or not when power on, even modules as well. After the power is on, all LED indicators will light up immediately and then all off except the power LED still keeps on. This represents a reset of the system.

• Firmware Loading

After resetting, the bootloader will load the firmware into the memory. It will take about 30 seconds, after that, the switch will flash all the LED once and automatically performs self-test and is in ready state.

2-1-2. 19-Inch Wiring Closet Rail Installing

Fig. 2-2

Caution: Allow a proper spacing and proper air ventilation for the cooling fan

at both sides of the chassis.

⇒ Wear a grounding device for electrostatic discharge. ⇒ Screw the mounting accessory to the front side of the switch (See Fig. 2-2). ⇒ Place the Chassis into the 19-inch wiring closet rail and locate it at the proper

position. Then, fix the Chassis by screwing it.

2-1-3. Cabling Requirements

To help ensure a successful installation and keep the network performance good, please take a care on the cabling requirement. Cables with worse specification will render the LAN to work poorly.

2-1-3-1. TP Ports Cabling

⇒ For Fast Ethernet TP network connection

⎯ The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of

100 meters.

⇒ Gigabit Ethernet TP network connection

⎯ The grade of the cable must be Cat. 5 or Cat. 5e with a maximum length of

100 meters. Cat. 5e is recommended.

2-1-3-2. 1000SX/LX SFP Module Cabling

It is more complex and comprehensive contrast to TP cabling in the fiber media. Basically, there are two categories of fiber, multi mode (MM) and single mode (SM). The later is categorized into several classes by the distance it supports. They are SX, LX, LHX, XD, and ZX. From the viewpoint of connector type, there mainly are LC and BIDI LC.

⎯ Gigabit Fiber with multi-mode LC SFP module

⎯ Gigabit Fiber with single-mode LC SFP module

⎯ Gigabit Fiber with BiDi LC 1310nm SFP module

⎯ Gigabit Fiber with BiDi LC 1550nm SFP module

The following table lists the types of fiber that we support and those else not listed here are available upon request.

2-1-3-3. Switch Cascading Topology

• Takes the Delay Time into Account

Theoretically, the switch partitions the collision domain for each port in switch cascading that you may up-link the switches unlimitedly. In practice, the network extension (cascading levels & overall diameter) must follow the constraint of the IEEE 802.3/802.3u/802.3z and other 802.1 series protocol specifications, in which the limitations are the timing requirement from physical signals defined by 802.3 series specification of Media Access Control (MAC) and PHY, and timer from some OSI layer 2 protocols such as 802.1d, 802.1q, LACP and so on.

The fiber, TP cables and devices’ bit-time delay (round trip) are as follows:

1000Base-X TP, Fiber 100Base-TX TP 100Base-FX Fiber

Round trip Delay: 4096 Round trip Delay: 512

Cat. 5 TP Wire: 11.12/m Cat. 5 TP Wire: 1.12/m Fiber Cable: 1.0/m

Fiber Cable : 10.10/m TP to fiber Converter: 56 Bit Time unit : 1ns (1sec./1000 Mega bit)

Bit Time unit: 0.01μs (1sec./100 Mega bit)

Table 2-2

Sum up all elements’ bit-time delay and the overall bit-time delay of wires/devices must be within Round Trip Delay (bit times) in a half-duplex network segment (collision domain). For full-duplex operation, this will not be applied. You may use the TP-Fiber module to extend the TP node distance over fiber optic and provide the long haul connection.

• Typical Network Topology in Deployment

A hierarchical network with minimum levels of switch may reduce the timing delay between server and client station. Basically, with this approach, it will minimize the number of switches in any one path; will lower the possibility of network loop and will improve network efficiency. If more than two switches are connected in the same network, select one switch as Level 1 switch and connect all other switches to it at Level 2. Server/Host is recommended to connect to the Level 1 switch. This is general if no VLAN or other special requireme nts are applied.

Case1: All switch ports are in the same local area network. Every port can access

each other (See Fig. 2-3).

Fig. 2-3 No VLAN Configuration Diagram

If VLAN is enabled and configured, each node in the network that can communicate each other directly is bounded in the same VLAN area.

Here VLAN area is defined by what VLAN you are using. The switch supports both port-based VLAN and tag-based VLAN. They are different in practical deployment, especially in physical location. The following diagram shows how it works and what the difference they are.

Case2a: Port-based VLAN (See Fig.2-4).

Fig. 2-4 Port-based VLAN Diagram

1. The same VLAN members could not be in different switches.

2. Every VLAN members could not access VLAN members each other.

3. The switch manager has to assign different na mes for each VLAN groups at one switch.

Case 2b: Port-based VLAN (See Fig.2-5).

Fig. 2-5 Port-based VLAN Diagram

1. VLAN1 members could not access VLAN2, VLAN3 and VLAN4 members.

2. VLAN2 members could not access VLAN1 and VLAN3 members, but they could access VLAN4 members.

3. VLAN3 members could not access VLAN1, VLAN2 and VLAN4.

4. VLAN4 members could not access VLAN1 and VLAN3 members, but they could access VLAN2 members.

Case3a: The same VLAN members can be at different switches with the same VID (See Fig. 2-6).

Fig. 2-6 Attribute-based VLAN Diagram

2-1-4. Configuring the Management Agent

We offer you three ways to startup the switch management function. They are RS-232 console, CLI, and Web. Users can use any one of them to monitor and configure the switch. You can touch them through the following procedures.

Section 2-1-4-1: Configuring through the Serial RS-232 Port Section 2-1-4-2: Configuring through the Ethernet Port Note: Please first modify the IP address, Subnet mask, Default gateway and DNS

through RS-232 console, and then do the next.

2-1-4-1. Serial RS-232 Port

To perform the configuration through RS-232 console port, the switch’s serial port must be directly connected to a DCE device, for example, a PC, through RS-232 cable with DB-9 connector. Next, run a terminal emulator with the default setting of the switch’s serial port. With this, you can communicate with the switch.

In the switch, RS-232 interface only supports baud rate 57.6k bps with 8 data bits, 1 stop bit, no parity check and no flow control.

RS-232 cable with female DB-9 connector at both ends

To configure the switch, please follow the procedures below:

1. Find the RS-232 DB-9 cable with female DB-9 connector bundled.

Normally, it just uses pins 2, 3 and 7. See also Appendix B for more details on Null Modem Cable Specifications.

2. Attaches the DB-9 female cable connector to the male serial RS-232

DB-9 connector on the switch.

3. Attaches the other end of the serial RS-232 DB-9 cable to PC’s serial

port, running a terminal emulator supporting VT100/ANSI terminal with The switch’s serial port default settings. For example, Windows98/2000/XP HyperTerminal utility.

Note: The switch’s serial port default settings are listed as follows:

Baud rate 57600 Stop bits 1 Data bits 8 Parity N Flow control none

4. When you complete the connection, then press <Enter> key. The login

prompt will be shown on the screen. The default username and password are shown as below:

Username = admin Password = admin

• Set IP Address, Subnet Mask and Default Gateway IP Address

Please refer to Fig. 2-7 CLI Management for details about LevelOne’s setting. They are default setting of IP address. You can first either configure your PC IP address or change IP address of the switch, next to change the IP address of default gateway and subnet mask.

For example, your network address is 10.1.1.0, and subnet mask is

255.255.255.0. You can change the switch’s default IP address 192.168.1.1 to

10.1.1.1 and set the subnet mask to be 255.255.255.0. Then, choose your default gateway, may be it is 10.1.1.254.

Default Value GSW-0890 Your Network Setting IP Address

Subnet Default Gateway

After completing these settings in the switch, it will reboot to have the configuration taken effect. After this step, you can operate the management through the network, no matter it is from a web browser or Network Management System (NMS).

2-1-4-2. Ethernet Port

There are three ways to configure and monitor the switch through the switch’s Ethernet port. They are CLI, Web browser and SNMP manager. The user interface for the last one is NMS dependent and does not cover here. We just introduce the first two types of management interface.

GSW-0890 L2 Managed Switch Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254

Ethernet LAN

Fig. 2-9

• Managing through Ethernet port

Before you communicate with the switch, you have to finish first the configuration of the IP address or to know the IP address of the switch. Then, follow the procedures listed below.

1. Set up a physical path between the configured the switch and a PC by a qualified UTP Cat. 5 cable with RJ-45 connector.

Note: If PC directly connects to the switch, you have to setup the same subnet mask between them. But, subnet mask may be different for the PC in the remote site. Please refer to Fig. 2-9 about the switch’s default IP address information.

2. Run CLI or web browser and follow the menu. Please refer to Chapter 3 and Chapter 4.

Fig. 2-10 the Login Screen for Web

2-1-5. IP Address Assignment

For IP address configuration, there are three parameters needed to be filled

in. They are IP address, Subnet Mask, Default Gateway and DNS.

IP address:

The address of the network device in the network is used for internetworking communication. Its address structure looks is shown in the Fig. 2-11. It is “classful” because it is split into predefined address classes or categories.

Each class has its own network range between the network identifier and host identifier in the 32 bits address. Each IP address comprises two parts: network identifier (address) and host identifier (address). The former indicates the network where the addressed host resides, and the latter indicates the individual host in the network which the address of host refers to. And the host identifier must be unique in the same LAN. Here the term of IP address we used is version 4, known as IPv4.

32 bits

Network identifier Host identifier

Fig. 2-11 IP address structure

With the classful addressing, it divides IP address into three classes, class A, class B and class C. The rest of IP addresses are for multicast and broadcast. The bit length of the network prefix is the same as that of the subnet mask and is denoted as IP address/X, for example, 192.168.1.0/24. Each class has its address range described below.

Class A:

Address is less than 126.255.255.255. There are a total of 126 networks can be defined because the address 0.0.0.0 is reserved for default route and

127.0.0.0/8 is reserved for loopback function.

Bit # 0 1 7 8

Network address Host address

Class B:

IP address range between 128.0.0.0 and 191.255.255.255. Each class B network has a 16-bit network prefix followed 16-bit host address. There are 16,384 (2^14)/16 networks able to be defined with a maximum of 65534 (2^16 –2) hosts per network.

Bit # 01 2 15 16

Network address Host address

Class C:

IP address range between 192.0.0.0 and 223.255.255.255. Each class C network has a 24-bit network prefix followed 8-bit host address. There are 2,097,152 (2^21)/24 networks able to be defined with a maximum of 254 (2^8 –2) hosts per network.

Bit # 0 1 2 3 23 24 31

110

Network address Host

Class D and E:

Class D is a class with first 4 MSB (Most significance bit) set to 1-1-1-0 and is used for IP Multicast. See also RFC 1112. Class E is a class with first 4 MSB set to 1-1-1-1 and is used for IP broadcast.

According to IANA (Internet Assigned Numbers Authority), there are three specific IP address blocks reserved and able to be used for extending internal network. We call it Private IP address and list below:

Class A 10.0.0.0 --- 10.255.255.255 Class B 172.16.0.0 --- 172.31.255.255 Class C 192.168.0.0 --- 192.168.25 5.255

Please refer to RFC 1597 and RFC 1466 for more information.

Subnet mask:

It means the sub-division of a class-based network or a CIDR block. The subnet is used to determine how to split an IP address to the network prefix and the host address in bitwise basis. It is designed to utilize IP address more efficiently and ease to manage IP network.

For a class B network, 128.1.2.3, it may have a subnet mask 255.255.0.0 in default, in which the first two bytes is with all 1s. This means more than 60 thousands of nodes in flat IP address will be at the same network. It’s too large to manage practically. Now if we divide it into smaller network by extending network prefix from 16 bits to, say 24 bits, that’s using its third byte to subnet this class B network. Now it has a subnet mask 255.255.255.0, in which each bit of the first three bytes is 1. It’s now clear that the first two bytes is used to identify the class B network, the third byte is used to identify the subnet within this class B network and, of course, the last byte is the host number .

Not all IP address is available in the sub-netted network. Two special addresses are reserved. They are the addresses with all zero’s and all one’s host number. For example, an IP address 128.1.2.128, what IP address reserved will be looked like? All 0s mean t he network itself, and all 1s mean IP broadcast.

128.1.2.128/25

10000000.00000001.00000010.1 0000000

25 bits

All 0s = 128.1.2.128

All 1s= 128.1.2.255

SubneNetwork

1 0000000 1 1111111

In this diagram, you can see the subnet mask with 25-bit long,

255.255.255.128, contains 126 members in the sub-netted network. Another is that the length of network prefix equals the number of the bit with 1s in that subnet mask. With this, you can easily count the number of IP addresses matched. The following table shows the result.

Prefix Length No. of IP matched No. of Addressable IP

/32 1 /31 2 /30 4 2 /29 8 6 /28 16 14 /27 32 30 /26 64 62 /25 128 126 /24 256 254 /23 512 510 /22 1024 1022 /21 2048 2046 /20 4096 4094 /19 8192 8190 /18 16384 16382 /17 32768 32766 /16 65536 65534

Table 2-4

According to the scheme above, a subnet mask 255.255.255.0 will partition a network with the class C. It means there will have a maximum of 254 effective nodes existed in this sub-netted network and is considered a physical network in an autonomous network. So it owns a network IP address which may looks like

168.1.2.0.

With the subnet mask, a bigger network can be cut into small pieces of network. If we want to have more than two independent networks in a worknet, a partition to the network must be performed. In this case, subnet mask must be applied.

For different network applications, the subnet mask may look like

255.255.255.240. This means it is a small network accommodating a maximum of 15 nodes in the network.

Default gateway:

For the routed packet, if the destination is not in the routing table, all the traffic is put into the device with the designated IP address, known as default router. Basically, it is a routing policy. The gateway setting is used for Trap Events Host only in the switch.

For assigning an IP address to the switch, you just have to check what the IP address of the network will be connected with the switch. Use the same network address and append your host address to it.

Fig. 2-12

First, IP Address: as shown in the Fig. 2-12, enter “192.168.1.1”, for instance. For sure, an IP address such as 192.168.1.x must be set on your PC.

Second, Subnet Mask: as shown in the Fig. 2-12, enter “255.255.255.0”. Any subnet mask such as 255.255.255.x is allowable in this case.

DNS:

The Domain Name Server translates human readable machine name to IP address. Every machine on the Internet has a unique IP address. A server generally has a static IP address. To connect to a server, the client needs to know the IP of the server. However, user generally uses the name to connect to the server. Thus, the switch DNS client program (such as a browser) will ask the DNS to resolve the IP address of the named server.

2-2. Typical Applications

The GSW-0890 implements 8 Gigabit Ethernet TP ports with auto MDIX and two slots for the removable module supporting comprehensive fiber types of connection, including LC and BiDi-LC SFP modules. For more details on the specification of the switch, please refer to Appendix A.

The switch is suitable for the following applications.

⎯ Central Site/Remote site application is used in carrier or ISP (See Fig. 2-13) ⎯ Peer-to-peer application is used in two remote offices (See Fig. 2-14) ⎯ Office network(See Fig. 2-15)

Central Site

Fig. 2-13 is a system wide basic reference connection diagram. This diagram demonstrates how the switch connects with other network devices and hosts.

Fig. 2-14 Peer-to-peer Network Connection

Fig. 2-15 Office Network Connection

3. Web-based Management

This chapter instructs you how to configure and manage the switch through the web user interface it supports, to access and manage the 6-Port 10/100/1000Mbps TP and 2-Port Gigabit TP/SFP Fiber management Ethernet switch. With this facility, you can easily access and monitor through any one port of the switch all the status of the switch, including MIBs status, each port activity, Spanning tree status, port aggregation status, multicast traffic, VLAN and priority status, even illegal access record and so on.

The default values of the managed switch are listed in the table below:

IP Address Subnet Mask Default Gateway Username Password

After the managed switch has been finished configuration in the CLI via the switch’s serial interface, you can browse it. For instance, type http://192.168.1.1 the address row in a browser, it will show the following screen (see Fig.3-1) and ask you inputting username and password in order to login and access authentication. The default username and password are both “admin”. For the first time to use, please enter the default username and password, then click the <Login> button. The login process now is completed.

192.168.1.1

255.255.255.0

192.168.1.254 admin admin

Table 3-1

Just click the link of “Forget Password” in WebUI (See Fig. 3-1) or input “Ctrl+Z” in CLI’s login screen (See Fig. 4-1~4-2) in case the user forgets the manager’s password. Then, the system will display a serial No. for the user. Write down this serial No. and contact your vendor, the vendor will give you a temporary password. Use this new password as ID and Password, and it will allow the user to login the system with manager authority temporarily. Due to the limit of this new password, the user only can login the system one time, therefore, please modify your password immediately after you login in the system successfully.

In this login menu, you have to input the complete username and password respectively, the switch will not give you a shortcut to username automatically. This looks inconvenient, but safer .

In the switch, it supports a simple user management function allowing only one administrator to configure the system at the same time. If there are two or more users using administrator’s identity, the switch will allow the only one who logins first to configure the system. The rest of users, even with administrator’s identity, can only monitor the system. For those who have no administrator’s identity, can only monitor the system. There are only a maximum of three users able to login simultaneously in the switch.

To optimize the display effect, we recommend you use Microsoft IE 6.0 above, Netscape V7.1 above or FireFox V1.00 above and have the resolution 1024x768. The switch supported neutral web browser interface.

In Fig. 3-2, for example, left section is the whole function tree with web user interface and we will travel it through this chapter .

3-1-2. IP Configuration

IP configuration is one of the most important configurations in the switch. Without the proper setting, network manager will not be able to manage or view the device. The switch supports both manual IP address setting and automatic IP address setting via DHCP server. When IP address is changed, you must reboot the switch to have the setting taken effect and use the new IP to browse for web management and CLI management.

Fig. 3-4 IP Address Configuration

Function name:

IP Configuration

Function description:

Set IP address, subnet mask, default gateway and DNS for the switch.

Parameter description:

DHCP Setting:

DHCP is the abbreviation of Dynamic Host Configuration Protocol. Here DHCP means a switch to turn ON or OFF the function.

The switch supports DHCP client used to get an IP address automatically if you set this function “Enable”. When enabled, the switch will issue the request to the DHCP server resided in the network to get an IP address. If DHCP server is down or does not exist, the switch will issue the request and show IP address is under requesting, until the DHCP server is up. Before getting an IP address from DHCP server, the device will not continue booting procedures. If set this field “Disable”, you’ll have to input IP address manually. For more details about IP address and DHCP, please see the Section 2-1-5 “IP Address Assignment” in this manual.

Default: Disable

IP address:

Users can configure the IP settings and fill in new values if users set the DHCP function “Disable”. Then, click <Apply> button to update.

When DHCP is disabled, Default: 192.168.1.1 If DHCP is enabled, this field is filled by DHCP server and will not allow

user manually set it any more.

Subnet mask:

Subnet mask is made for the purpose to get more network address because any IP device in a network must own its IP address, composed of Network address and Host address, otherwise can’t communicate with other devices each other. But unfortunately, the network classes A, B, and C are all too large to fit for almost all networks, hence, subnet mask is introduced to solve this problem. Subnet mask uses some bits from host address and makes an IP address looked Network address, Subnet mask number and host address. It is shown in the following figure. This reduces the total IP number of a network able to support, by the amount of 2 power of the bit number of subnet number (2^(bit number of subnet number)).

32 bits

Subnet mask is used to set the subnet mask value, which should be the same value as that of the other devices resided in the same network it attaches.

For more information, please also see the Section 2-1-5 “IP Address Assignment” in this manual.

Default: 255.255.255.0

Default gateway:

Set an IP address for a gateway to handle those packets that do not meet the routing rules predefined in the device. If a packet does not meet the criteria for other pre-defined path, it must be forwarded to a default router on a default path. This means any packet with undefined IP address in the routing table will be sent to this device unconditionally.

Default: 192.168.1.254

Network ID Host ID

Subnet number

DNS:

It is Domain Name Server used to serve the translation between IP address and name address.

The switch supports DNS client function to re-route the mnemonic name address to DNS server to get its associated IP address for accessing Internet. User can specify a DNS IP address for the switch. With this, the switch can translate a mnemonic name address into an IP addre ss.

There are two ways to specify the IP address of DNS. One is fixed mode, which manually specifies its IP address, the other is dynamic mode, which is assigned by DHCP server while DHCP is enabled. DNS can help you easily remember the mnemonic address name with the meaningful words in it. Default is no assignment of DNS address.

Default: 0.0.0.0

3-1-3. Time Configuration

The switch provides manual and automatic ways to set the system time via NTP. Manual setting is simple and you just input “Year”, “Month”, “Day”, “Hour”, “Minute” and “Second” within the valid value range indicated in each item. If you input an invalid value, for example, 61 in minute, the switch will clamp the figure to

59.

NTP is a well-known protocol used to synchronize the clock of the switch system time over a network. NTP, an internet draft standard formalized in RFC 1305, has been adopted on the system is version 3 protocol. The switch provides four built-in NTP server IP addresses resided in the Internet and an user-defined NTP server IP address. The time zone is Greenwich-centered which uses the expression form of GMT+/- xx hours.

Function name:

Time

Function description:

Set the system time by manual input or set it by syncing from Time servers. The function also supports daylight saving for different area’s time adjustment.

Parameter description: Current Time:

Show the current time of the system.

Manual:

This is the function to adjust the time manually. Filling the valid figures in the fields of Year, Month, Day, Hour, Minute and Second respectively and press <Apply> button, time is adjusted. The valid figures for the parameter Year, Month, Day, Hour, Minute and Second are >=2000, 1-12, 1-31, 0-23, 0-59 and 0-59 respectively. Input the wrong figure and press <Apply> button, the device will reject the time adjustment request. There

is no time zone setting in Manual mode.

Default: Year = 2000, Month = 1, Day = 1

Hour = 0, Minute = 0, Second = 0

NTP:

NTP is Network Time Protocol and is used to sync the network time based Greenwich Mean Time (GMT). If use the NTP mode and select a built-in NTP time server or manually specify an user-defined NTP server as well as Time Zone, the switch will sync the time in a short after pressing <Apply> button. Though it synchronizes the time automatically, NTP does not update the time periodically without user’s processing.

Time Zone is an offset time off GMT. You have to select the time zone first and then perform time sync via NTP because the switch will combine this time zone offset and updated NTP time to come out the local time, otherwise, you will not able to get the correct time. The switch supports configurable time zone from –12 to +13 step 1 hour.

Default Time zone: +8 Hrs.

Daylight Saving:

Daylight saving is adopted in some countries. If set, it will adjust the time lag or in advance in unit of hours, according to the starting date and the ending date. For example, if you set the day light saving to be 1 hour. When the time passes over the starting time, the system time will be increased one hour after one minute at the time since it passed over. And when the time passes over the ending time, the system time will be decreased one hour after one minute at the time since it passed over.

The switch supports valid configurable day light saving time is –5 ~ +5 step one hour. The zero for this parameter means it need not have to adjust current time, equivalent to in-act daylight saving. You don’t have to set the starting/ending date as well. If you set daylight saving to be nonzero, you have to set the starting/ending date as well; otherwise, the daylight saving function will not be activated.

Default for Daylight Saving: 0. The following parameters are configurable for the function Daylight

3-1-6. Virtual Stack

Function name:

Virtual Stack

Function description:

Virtual Stack Management(VSM) is the group management function. Through the proper configuration of this function, switches in the same LAN will be grouped automatically. And among these switch, one switch will be a master machine, and the others in this group will become the slave devices.

VSM offers a simple centralized management function. It is not necessary to remember the address of all devices, manager is capable of managing the network with knowing the address of the Master machine. Instead of SNMP or Telnet UI, VSM is only available in Web UI. While one switch become the Master, two rows of buttons for group device will appear on the top of its Web UI. By pressing these buttons, user will be allowed to connect the Web UI of the devices of the group in the same window without the login of these device.

The most top-left button is only for Master device(See Fig.3-9). The background color of the button you press will be changed to represent that the device is under your management.

Note: It will remove the grouping temporarily in case that you login the switch

via the console.

The device of the group will be shown as station address ( the last number of IP Address) + device name on the button (e.g. 196_GSW-0890), otherwise it will show ” ---- “ if no corresponding device exists.

Once the devices join the group successfully, then they are merely able to be managed via Master device, and user will fail to manage them via telnet/console/web individually.

Up to 16 devices can be grouped for VSM, however, only one Master is allowed to exist in each group. For Master redundancy, user may configure more than two devices as Master device, however, the Master device with the smaller MAC value will be the Master one. All of these 16 devices can become Master device and back up with each other .

Parameter description:

Fig. 3-8

State:

It is used for the activation or de-activation of VSM. Default is Enable.

Role:

The role that the switch would like to play in virtual stack. Two types of roles, including master and slave are offered for option. Default is Master.

Group ID:

It is the group identifier (GID) which signs for VSM. Valid letters are A-Z, a-z, 0-9, “

- “ and “_” characters. The maximal length is 15 characters.

Four functions, including Port Status, Port Configuration, Simple Counter and Detail Counter are contained in this function folder for port monitor and management. Each of them will be described in detail orderly in the following sections.

Port Configuration

Status

Configuration

Simple Counter

Detail Counter

3-2-1.Port Status

The function Port Status gathers the information of all ports’ current status and reports it by the order of port number, link status, port state, Auto-Negotiation status, speed/duplex and flow control. An extra media type information for the module ports 7 and 8 is also offered (See Fig. 3-11).

Fig. 3-10

Function name:

Port Status

Function Description:

Report the latest updated status of all ports in this switch. When any one of the ports in the switch changes its parameter displayed in the page, it will be automatically refreshed the port current status about every 5 seconds.

Parameter Description:

Port No:

Display the port number. The number is 1 – 8. Both port 7 and 8 are optional modules.

Media:

Show the media type adopted in all ports. The Port 7 and Port 8 are optional modules, which support either fiber or UTP media with either Gigabit Ethernet (1000Mbps) or 10/100Mbps Fast Ethernet port. They may have different media types and speed. Especially, fiber port has comprehensive types of connector, distance, fiber mode and so on. The switch describes the module ports with the following page.

Link:

Show that if the link on the port is active or not. If the link is connected to a working-well device, the Link will show the link “Up”; otherwise, it will show “Down”. This is determined by the hardware on both devices of the connection.

No default value.

State:

Show that the communication function of the port is “Enabled” or “Disabled”. When it is enabled, traffic can be transmitted and received via this port. When it is disabled, no traffic can be transferred through this port. Port State is co nfigured by user.

Default: Enabled.

Auto Negotiation:

Show the exchange mode of Ethernet MAC. There are two modes supported in the switch. They are auto-negotiation mode “Enabled” and forced mode “Disabled”. When in “Enabled” mode, this function will automatically negotiate by hardware itself and exchange each other the capability of speed and duplex mode with other site which is linked, and comes out the best communication way. When in “Disabled” mode, both parties must have the same setting of speed and duplex, otherwise, both of them will not be linked. In this case, the link result is “Down”.

Default: Enabled

Speed / Duplex Mode:

Display the speed and duplex of all port. There are three speeds 10Mbps, 100Mbps and 1000Mbps supported for TP media, and the duplex supported is half duplex and full duplex. If the media is 1Gbps fiber, it is 1000Mbps supported only. The status of speed/duplex mode is determined by 1) the negotiation of both local port and link partner in “Auto Speed” mode or 2) user setting in “Force” mode. The local port has to be preset its capability.

Default: None, depends on the result of the negotiation.

Flow Control:

Show each port’s flow control status. There are two types of flow control in Ethernet, Backpressure for half-

duplex operation and Pause flow control (IEEE802.3x) for full-duplex operation. The switch supports both of them.

Default: Disabled

Wait State:

For 10/100M ports, there is no side effect on this setting. For Gigabit ports, setting of Wait-State will remove the issue with ignored

pause frames but resolve in the minimum interframe gap being at least 14 bytes instead of the usual 12 bytes. This applies for uncongested traffic as well. The larger interframe gap will result in throughput rates less than 100%. For example, a stream of 64-byte frames and a stream of 1518-byte frames, their maximum throughput is 97.7% and 99.9% respectively.

Parameter description of Port 7 and Port 8:

Port Configuration is applied to change the setting of each port. In this configuration function, you can set/reset the following functions. All of them are described in detail below.

Fig. 3-12

Function name:

Port Configuration

Function description:

It is used to set each port’s operation mode. The switch supports 3 parameters for each port. They are state, mode and flow control.

Parameter description:

State:

Set the communication capability of the port is Enabled or Disabled. When enabled, traffic can be transmitted and received via this port. When disabled, the port is blocked and no traffic can be transferred through this port. Port State is configurable by the user. There are only two states “Enable” and “Disable” able to choose. If you set a port’s state “Disable”, then that port is prohibited to pass any traffic, even it looks Link up.

Default: Enable.

Mode:

Set the speed and duplex of the port. In speed, if the media is 1Gbps fiber, it is always 1000Mbps and the duplex is full only. If the media is TP, the Speed/Duplex is comprised of the combination of speed mode, 10/100/1000Mbps, and duplex mode, full duplex and half duplex. The following table summarized the function the media supports.

Media type NWay Speed Duplex

1000M TP ON/OFF 10/100/1000M Full for all, Half for 10/100 1000M Fiber ON/OFF 1000M Full

In Auto-negotiation mode, no default value. In Forced mode, default value depends on your setting.

Flow Control:

There are two modes to choose in flow control, including Enable and Disable. If flow control is set Enable, both parties can send PAUSE frame to the transmitting device(s) if the receiving port is too busy to handle. When it is set Disable, there will be no flow control in the port. It drops the packet if too much to handle.

Default: Enable.

Wait State:

For more details about this parameter please refer to section 3-2-1. Default: Disable.

3-2-3. Simple Counter

3-4. Bandwidth Management

Function name:

Bandwidth Management

Function description:

Bandwidth Management function is used to set up the limit of Ingress and Egress bandwidth for each port.

Note:

Each port of the switch owns 16KB packet buffer. The packet buffer size will be reduced when the bandwidth rate limitation is enabled, whi ch ma y cause that jumbo frame cannot be forwarded. Please avoid enabling jumbo frame and bandwidth rating functions at the same time.

Parameter description:

Port Number:

Fig. 3-16

Choose the port that you would like this function to work on it. Valid range of the port is 1~8.

All Traffic for Ingress Rate Limiting(Policing):

Set up the limit of Ingress bandwidth for the port you choose. Incoming traffic will be discarded if the rate exceeds the value you set up in Data Rate field. Pause frames are also generated if flow control is enabled. The format of the packet limits to unicast, broadcast and multicast. Valid range is 0~1000.

Broadcast & Multicasat for Ingress Rate Limiting (Policing):

Set up the limit of Ingress bandwidth for the port you choose. Incoming traffic will be discarded if the rate exceeds the value you set up in Data Rate field. The format of the packet limits to broadcast and multicast. Valid range is 0~1000.

All Traf fic for Egress Rate Limiting(Shap ing):

Set up the limit of Egress bandwidth for the port you choose. Packet transmission will be delayed if the rate exceeds the value you set up in Data Rate field. Traffic may be lost if egress buffers run full. The format of the packet limits to unicast, broadcast and multicast. Valid range is 0~1000.

3-5. QoS(Quality of Service) Configuration

The switch offers powerful 5 kinds of QoS functions. There are Per Port Priority that you can assign each port to different precedence, VLAN Tag priority that can make precedence of 8 priorities, IP TOS Classification, IP TCP/UDP Port Classification and IP DiffServe Classification.

In Quality of Service (QoS) Configuration, there is one option named” Default Class”. As you had selected one of the five QoS functions, then some packets that did not belong to this QoS setting would be viewed as Default Class. For instance, if you set QoS function as VLAN Tag Priority mode, and then choose Default Class as High, finally, the priority of the packets with no tag will be considered as High priority precedence. The initial value of the Default Class is High.

Fig. 3-17

Function name:

Per Port Priority

Function description:

We can assign QoS Priority, including High and Low for each port. For example, if we transmit IP packets from Port 2 and Port 3 at the speed of 1Gbps to Port 1, and set the Class of Port 2 as High and Port 3 as Low, then the packets of Port 3 will be dropped when the congestion happens because Port 2 owns higher precedence of transmitting packets.

Parameter description:

Port No:

User can choose the port (1~8) respectively with Priority Class on Per Port Priority function.

Class:

User can set up High Priority or Low Priority for each port respectively.

Fig. 3-18

Function name:

VLAN Tag Priority

Function description:

In vlan tag, there are 3 bits belonging to priority. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low priority for each traffic class. For instance, if we let VLAN-tagged priority 0 0 0 be high priority and VLAN-tagged priority 0 0 1 be Lo w Priority, and then make port 1, 2, 3 be in the vlan 2. We sent the packets that have the value 0 0 0 in vlantagged field and VID equals 2 from the port 2 and the packets that have the value 0 0 1 in vlan-tagged field and VID equals 2 from the port 3 into the switch. We let the two kinds of packets be transmitted for port 1 until the port results in congestion. The result is that the packets will be dropped partially from the port 3 because the packets that belong to Low Priority. For the use of VLAN Tag Priority function, please press <Configure> button at the right section for setting in advance.

Fig. 3-19

Parameter description:

Quality of Service (QoS) Vlan Tag Configuration:

Used for setting up the QoS belongs to Vlan operation.

Port:

User can set up the port (1~8) respectively to let Vlan Tag QoS function work on them. If you would like to set up all ports at a time, user is also allowed to choose “All” in the selection list to simplify the procedure of configuration.

Bit 0, Bit 1, Bit 2:

According to the arrangement of VLAN-tagged priority, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0 and 1 1 1.

Class:

8 kinds of traffic as mentioned above, user can set up High Pri ority or Low Priority for each port respectively.

Function name:

IP ToS Classification

Function description:

Another QoS function is the application of Layer 3 on network framework. We focus on TOS field of IP header. There are three bits in TOS field. We means bit 5~7 of TOS field that we will use. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0, 1 1 1. As long as we change bit 5~7 of TOS field of IP header, we will create the 8 traffic packets we meant before. Moreover, we can set High priority or Low priority for each traffic class. For instance, if we let TOS 0 0 0 be high priority and TOS 0 0 1 be Low Priority, we sent in the packets that have bit 5~7 of TOS Field appears 0 0 0 from the port 2 and the packets that have bit 5~7 of TOS Field appears 0 0 1 from the port 3. We let the two kinds of packets be transmitted for port 1 until the port results in congestion. The result is that the packets will be dropped partially from the port 3 because the packets that belong to Low Priority.

Fig. 3-20

Parameter description:

Quality of Service (QoS) ToS Configuration:

Used for setting up the QoS in Layer 3.

Port:

User can set up the port (1~8) respectively to let TOS QoS function work on them. If you would like to set up all ports at a time, user is also allowed to choose “All” in the selection list to simplify the procedure of configuration.

Bit 0, Bit 1, Bit 2:

According to the arrangement of Bit 5 ~ Bit 7 in TOS Field of IP Header, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0 and 1 1 1.

Class:

8 kinds of traffic as mentioned above, user can set up High Pri ority or Low Priority for each port respectively.

Function name:

IP TCP/UDP Port Classification

Function description:

In L4 QoS Configuration, you can enter one of these special network transmission events, for example we use” Down prioritize web browsing, e-mail, FTP and news “L4 QoS Configuration and click <Apply> button, and then click <Advance >>> 443, 25, 110, 20, 21, 69, 119, 2009 have already existed and defined for your using but it is fine that you modify this pre-defined TCP/UDP port with other port number you prefer. In ” Down prioritize web browsing, e-mail, FTP and news “ L4 QoS Configuration with default setting, special defined TCP/UDP port possesses lower QoS traffic than Default class ( all other TCP/UDP ports such as port 81,82,83,84,85, etc.). Giving an example, when we transmit TCP packets with port number 80 at each of port 2 and port number 81 at port 3 to port 1 until the congestion happens. The packets from port 3 will be dropped by port 1 because the TCP packets have port number 80 is high priority and will have higher precedence to be sent out from port 1.

Parameter description:

Disable IP TCP/UDP Port Classification:
