1. Introduction

1-1. Overview of SW24GF

SW24GF, a 24-port Gigabit L2 Plus Managed Switch, is a standard switch that meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet specifications. 16-Port 1000Mbps SFP and 8-Port Combo Gigabit TP/SFP Fiber dual media management Ethernet switch. The switch can be managed through RS-232 serial port via directly connection, or through Ethernet port using CLI or Web-based management unit, associated with SNMP agent. With the SNMP agent, the network administrator can logon the switch to monitor, configure and control each port’s activity in a friendly way. The overall network management is enhanced and the network efficiency is also improved to accommodate high bandwidth applications. In addition, the switch features comprehensive and useful functions such as QoS (Quality of Service), Spanning Tree, VLAN, Port Trunking, Bandwidth Control, Port Security, SNMP/RMON, IGMP Snooping capability via the intelligent software. It is suitable for both metro-LAN and office applications.

Others the switch increase support the Power saving for reduce the power consumption with "ActiPHY Power Management" and "Perfect Reach Power Management" two technique. It could efficient saving the switch power with auto detect the client idle and cable length to provide different power.

In this switch, Port 1 and Port 8 include two types of media --- TP and SFP Fiber (LC, BiDi LC…); this port supports 10/100/1000Mbps TP or 1000Mbps SFP Fiber with auto-detected function. 1000Mbps SFP Fiber transceiver is used for highspeed connection expansion.

⎯ 1000Mbps LC, Multi-Mode, SFP Fiber transceiver ⎯ 1000Mbps LC, 10km, SFP Fiber transceiver ⎯ 1000Mbps LC, 30km, SFP Fiber transceiver ⎯ 1000Mbps LC, 50km, SFP Fiber transceiver ⎯ 1000Mbps BiDi LC, 20km, 1550nm SFP Fiber WDM transceiver ⎯ 1000Mbps BiDi LC, 20km, 1310nm SFP Fiber WDM transceiver

10/100/1000Mbps TP is a standard Ethernet port that meets all IEEE

802.3/u/x/z Gigabit, Fast Ethernet specifications. 1000Mbps SFP Fiber transceiver is a Gigabit Ethernet port that fully complies with all IEEE 802.3z and 1000BaseSX/LX standards.

1000Mbps Single Fiber WDM (BiDi) transceiver is designed with an optic Wavelength Division Multiplexing (WDM) technology that transports bi-directional full duplex signal over a single fiber simultaneously.

For upgrading firmware, please refer to the Section 3-21 or Section 4-2-2 for more details. The switch will not stop operating while upgrading firmware and after that, the configuration keeps unchanged.

Note:

The switch was for using indoor purpose, if it was used in outdoor environment or connect with cable to outdoor then it must to use a lightning arrester to protect the switch.

• Key Features in the Device

QoS:

Support Quality of Service by the IEEE 802.1P standard. There are two priority queue and packet transmission schedule.

Spanni ng Tree:

Support IEEE 802.1D, IEEE 802.1w (RSTP: Rapid Spanning Tree Protocol) standards.

VLAN:

Support Port-based VLAN and IEEE802.1Q Tag VLAN. Support 256 active VLANs and VLAN ID 1~4094.

Port Trunking:

Support static port trunking and port trunking with IEEE 802.3ad LACP.

Bandwidth Control:

Support ingress and egress per port bandwidth control.

Port Security:

Support allowed, denied forwarding and port security with MAC address.

SNMP/RMON:

SNMP agent and RMON MIB. In the device, SNMP agent is a client software which is operating over SNMP protocol used to receive the command from SNMP manager (server site) and echo the corresponded data, i.e. MIB object. Besides, SNMP agent will actively issue TRAP information when happened. RMON is the abbreviation of Remote Network Monitoring and is a branch of the SNMP MIB. The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB (RFC 1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet MIB (RFC 1643) and so on.

IGMP Snooping:

Support IGMP version 2 (RFC 2236): The function IGMP snooping is used to establish the multicast groups to forward the multicast packet to the member ports, and, in nature, avoid wasting the bandwidth while IP multicast packets are running over the network.

IGMP Proxy:

The implementation of IP multicast processing. The switch supports IGMP version 1 and IGMP version 2, efficient use of network bandwidth, and fast response time for channel changing. IGMP version 1 (IGMPv1) is described in RFC1112, and IGMP version 2 (IGMPv2) is described in RFC

2236. Hosts interact with the system through the exchange of IGMP messages. Similarly, when you configure IGMP proxy, the system interacts with the router on its upstream interface through the exchange of IGMP messages. However, when acting as the proxy, the system performs the host portion of the IGMP task on the upstream interface as follows:

• When queried, sends group membership report s to the group.

• When one of its hosts joins a multicast addre s s group to which none of

its other hosts belong, sends unsolicited group membership reports to that group.

• When the last of its hosts in a particula r multica st gro up leaves the

group, sends an unsolicited leave group membership report to the allrouters group (244.0.0.2).

DHCP Snooping:

This feature enables the DHCP Snooping to include information about client when forwarding DHCP requests from a DHCP client to a DHCP server via Trust Port. DHCP snooping can be configured on LAN switches to harden the security on the LAN to only allow clients with specific IP/ to have access to the network. In short, DHCP snooping ensures IP integrity on a Layer 2 switched domain.

Power Saving:

The Power saving using the "ActiPHY Power Management" and "Perfect Reach Power Management" two techniques to detect the client idle and cable length automatically and provides the different power. It could efficient to save the switch power and reduce the power consumption.

Q-in-Q VLAN for performance & security:

The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. Q-in-Q, the use of double VLAN tags is an efficient method for enabling Subscriber Aggregation. This is very useful in the MAN.

Link Layer Discovery Protocol (LLDP)

IEEE Standard─ 802.1AB （ Link Layer Discovery Protocol），Provide more easy debug tool and enhance the networking management availability,

Others it can provide auto-discovery device and topology providing.

MAC addresses

MVR:

Multicast VLAN Registration (MVR) can support carrier to serve content provider using multicast for Video streaming application in the network. Each content provider Video streaming has a dedicated multicast VLAN. The MVR routes packets received in a multicast source VLAN to one or more receive VLANs. Clients are in the receive VLANs and the multicast server is in the source VLAN.

Access Control List (ACL):

The ACLs are divided into Ether Types. IPv4, ARP protocol, MAC and VLAN parameters etc. Here we will just go over the standard and extended access lists for TCP/IP. As you create ACEs for ingress classification, you can assign a policy for each port, the policy number is 1-8, and however, each policy can be applied to any port. This makes it very easy to determine what type of ACL policy you will be working with.

IP-MAC-Port Binding:

The IP network layer uses a four-byte address. The Ethernet link layer uses a six-byte MAC address. Binding these two address types together allows the transmission of data between the layers. The primary purpose of IPMAC binding is to restrict the access to a switch to a number of authorized users. Only the authorized client can access the Switch’s port by checking the pair of IP-MAC Addresses and port number with the pre-configured database. If an unauthorized user tries to access an IP-MAC binding enabled port, the system will block the access by dropping its packet.

2. Installation

2-1. Starting SW24GF 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 to the SW24GF 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 u nplug 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

Fig. 2-1 Installation of Optional SFP Fiber Transceive

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

slot(s)

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

Note: The switch supports the SFP Vendor includes: Manufacture,

Agilent, Avago and Finisa

• TP Port and Cable Installation

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

cable, straight-through and crossed-over 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 boot loader 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. Installing Chassis to a 19-Inch Wiring Closet Rail

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. Cabling Requirements for TP Ports

⇒ 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. Cabling Requirements for 1000SX/LX SFP Module

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 in 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 requirements are applied.

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

each other (See Fig. 2-3).

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. 2-3 No VLAN Configuration 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 names for each VLAN groups at one switch.

Fig. 2-4 Port-based VLAN Diagram

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

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).

2-1-4. Configuring the Management Agent of SW24GF

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 the Management Agent of SW24GF through the Serial

RS-232 Port

Section 2-1-4-2: Configuring the Management Agent of SW24GF 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. Configuring the Management Agent of SW24GF through the 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 115200 bps with 8 data bits, 1 stop bit, no parity check and no flow control.

RS-232 DB-9 Connector

SW24GF L2 Managed Sw itch Default IP Setting: IP address = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254

Fig. 2-7

Terminal or Terminal Emulator

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 115200 Stop bits 1 Data bits 8 Parity N Flow control none

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

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 ex-factory IP 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 SW24GF 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).

192.168.1.1 10.1.1.1

255.255.255.0 255.255.255.0

Table 2-3

2-1-4-2. Configuring the Management Agent of SW24GF through the 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.

• Managing SW24GF 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 31

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 31

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 address

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 belo w:

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 --- 192.168.255.255

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.

10000000.00000001.00000010.1 0000000

etwork

25 bits

All 0s = 128.1.2.128

All 1s= 128.1.2.255

Subne

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 SW24GF 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

3. Operation of

Web-based Management

This chapter instructs you how to configure and manage the SW24GF through the web user interface it supports, to access and manage the 16-Port Gigabit SFP and 8-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

Table 3-1

192.168.1.1

255.255.255.0

192.168.1.254 admin admin

After the managed switch has been finished configuration in the CLI via the switch’s serial interface, you can browse it. For instance, type 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, and then click the <Login> button. The login process now is completed.

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.

Password: admin

Fig. 3-5

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 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 a 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.

RFC 1305,

Parameter description:

Fig. 3-6

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 steps 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

Saving and described in detail.

Day Light Saving St art: This is used to set when to start performing the day light saving time.

Mth:

Range is 1 ~ 12. Default: 1

Day:

Range is 1 ~ 31. Default: 1

Hour:

Range is 0 ~ 23.

Default: 0 Day Light Saving End: This is used to set when to stop performing the daylight saving time.

Mth:

Range is 1 ~ 12.

Default: 1

Day:

Range is 1 ~ 31.

Default: 1

Hour:

Range is 0 ~ 23.

Default: 0

3-1-4. 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.

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

Fig. 3-7 IP Address Configuration

IP address:

Subnet mask:

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 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

Network ID Host ID

Subnet number

Host ID

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 address.

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

3-1-5. Loop Detection

The loop detection is used to detect the presence of traffic. When switch receives packet’s(looping detection frame) MAC address the sa me as oneself from port, show Loop detection happens. The port will be locked when it received the looping detection frames. If you want to resume the locked port, please find out the looping path and take off the looping path, then select the resume the locked port and click on “Resume” to turn on the locked ports.

Function name:

3-1-8. 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 becomes 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 devices.

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_GS-2224L), 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.

Fig. 3-10-1

Parameter description:

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 characte rs.

3-2-1. Port Configuration

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.

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.

Fig. 3-12

Parameter description:

Port: To display the port index

Media: To display the port media type with UTP or SFP Speed:

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.

Maximum Frame:

This module offers 1518~9600 (Bytes) length to make the long pa cket.

Excessive Collision Mode:

There are two modes to choose when excessive collision happens in half-duplex condition as below:

Discard: The “Discard” mode determines whether the MAC drop frames after an excessive collision has occurred. If set, a frame is dropped after excessive collisions. This is IEEE Std 802.3 half-duplex flow control operation.

Restart: The “Restart” mode determines whether the MAC retransmits frames after an excessive collision has occurred. If set, a frame is not dropped after excessive collisions, but the backoff sequence is restarted. This is a violation of IEEE Std 802.3, but is useful in non-dropping halfduplex flow control operation.

Description:

Description of device ports can not include “# % & ‘+ \.

3-2-2.Port Status

Parameter description:

Power Saving:

The parameter will enable or disable to verify switches have the ability to consider the length of any Ethernet cable connected for adjustment of power usage accordingly. Shorter lengths require less power. link-down mode removes power for each port that does not have a device attached.

Default: Disable.

Fig. 3-16-1

3-3. VLAN

The switch supports Tag-based VLAN (802.1Q) and Port-based VLAN. Support 4094 active VLANs and VLAN ID 1~4094. VLAN configuration is used to partition your LAN into small ones as your demand. Properly configuring it, you can gain not only improving security and increasing performance but greatly reducing VLAN management.

3-3-1. VLAN Mode

Function name:

VLAN Mode Setting

Function description:

The VLAN Mode Selection function includes five modes: Port-based, Tagbased, Metro Mode, Double-tag and Disable, you can choose one of them by pulling down list and selecting an item. Then, click <Apply> button, the settings will take effect immediately.

Parameter description:

VLAN Mode:

Port-based:

Port-based VLAN is defined by port. Any packet coming in or outgoing from any one port of a port-based VLAN will be accepted. No filtering criterion applies in port-based VLAN. The only criterion is the physical port you connect to. For example, for a port-based VLAN named PVLAN-1 contains port members Port 1&2&3&4. If you are on the port 1, you can communicate with port 2&3&4. If you are on the port 5, then you cannot talk to them. Each port-based VLAN you built up must be assigned a group name. This switch can support up to maximal 24 port-based VLAN groups.

Fig. 3-17

Tag-based:

Tag-based VLAN identifies its member by VID. This is quite different from port-based VLAN. If there are any more rules in ingress filtering list or egress filtering list, the packet will be screened with more filtering criteria to determine if it can be forwarded. The switch supports supplement of 802.1q. For more details, please see the section VLAN in Chapter 3.

Each tag-based VLAN you built up must be assigned VLAN name and VLAN ID. Valid VLAN ID is 1-4094. User can create total up to

4094 Tag VLAN groups.

3-3-4. Ports

Function name:

VLAN Port Configuration

Function description:

In VLAN Tag Rule Setting, user can input VID number to each port. The range of VID number is from 1 to 4094. User also can choose ingress filtering rules to each port. There are two ingress filtering rules which can be applied to the switch. The Ingress Filtering Rule 1 is “forward only packets with VID matching this port’s configured VID”. The Ingress Filtering Rule 2 is “drop untagged frame”. You can also select the Role of each port as Access, Trunk, or Hybrid.

Parameter description:

Port 1-24:

Port number.

VLAN Aware:

Based on IEEE 802.1Q VLAN tag to forward packet

Ingress Filtering:

Discard other VLAN group packets, only forward this port joined VLAN group packets

Frame Type:

All: Forward all tagged and untagged packets Tagged: Forward tagged packets only and discard untagged packets

Fig. 3-24

PVID:

Role:

Untag VID:

Double T ag :

This PVID range will be 1-4094. Before you set a number x as PVID, you have to create a Tag-based VLAN with VID x. For example, if port x receives an untagged packet, the switch will apply the PVID (assume as VID y) of port x to tag this packet, the packet then will be forwarded as the tagged packet with VID y.

This is an egress rule of the port. Here you can choose Access, Trunk or Hybrid. Trunk means the outgoing packets must carry VLAN tag header. Access means the outgoing packets carry no VLAN tag header. If packets have double VLAN tags, one will be dropped and the other will still be left. As to Hybrid, it is similar to Trunk, and both of them will tagout. When the port is set to Hybrid, its packets will be untagged out if the VID of the outgoing packets with tag is the same as the one in the field of Untag VID of this port.

Valid range is 1~4094. It works only when Role is set to Hybrid.

Double-tag mode belongs to the tag-based mode, however, it would treat all frames as the untagged ones, which means that tag with PVID will be added into all packets. Then, these packets will be forwarded as Tagbased VLAN. So, the incoming packets with tag will become the doubletag ones. Scroll to enable the function and default is Disable.

3-3-5. Port Isolation

Function name:

Port Isolation

Function description:

Port Isolation provides for an apparatus and method to isolate ports on layer 2 switches on the same VLAN to restrict traffic flow. The apparatus comprises a switch having said plurality of ports, each port configured as a protected port or a non-protected port. An address table memory stores an address table having a destination address and port number pair. A forwarding map generator generates a forwarding map which is responsive to a destination address of a data packet. The method for isolating ports on a layer 2 switch comprises configuring each of the ports on the layer 2 switch as a protected port or a non-protected port. A destination address on an data packet is matched with a physical address on said layer 2 switch and a forwarding map is generated for the data packet based upon the destination address on the data packet. The data packet is then sent to the plurality of ports pursuant to the forwarding map generated based upon whether the ingress port was configured as a protected or non-protected port.

3-6. QoS(Quality of Service) Configuration

The switch supports four QoS queues per port with strict or weighted fair queuing scheduling. There are 24 QoS Control Lists (QCL) for advance programmable QoS classification, based on IEEE 802.1p, Ether type, VID, IPv4/IPv6 DSCP and UDP/TCP ports and ranges.

High flexibility in the classification of incoming frames to a QoS class. The QoS classification looks for information up to Layer 4, including IPv4 and IPv6 DSCP, IPv4 TCP/UDP port numbers, and user priority of tagged frames. This QoS classification mechanism is implemented in a QoS control list (QCL). The QoS class assigned to a frame is used throughout the device for providing queuing, scheduling, and congestion control guarantees to the frame according to what was configured for that specific QoS class.

The switch support advanced memory control mechanisms providing excellent performance of all QoS classes under any traffic scenario, including jumbo frame. A super priority queue with dedicated memory and strict highest priority in the arbitration. The ingress super priority queue allows traffic recognized as CPU traffic to be received and queued for transmission to the CPU even when all the QoS class queues are congested.
