2. Installation 2-1. Starting 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED 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 Installing Optional SFP Fiber Transceivers to the L2 Managed Switch Note: If you have no modules, please skip this section.
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 pin-outs for RJ-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.
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.
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.
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.
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.
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.
2-1-4. Configuring the Management Agent of 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH We offer you three ways to startup the switch management function. They are RS232 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.
2-1-4-1. Configuring the Management Agent 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 57.
Set IP Address, Subnet Mask and Default Gateway IP Address Please refer to Fig. 2-7 CLI Management for details about factory 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.
2-1-4-2. Configuring the Management Agent 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. Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.254 Ethernet LAN Assign a reasonable IP address, For example: IP = 192.
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.
With the class 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.
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 1-1-11 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 Class B Class C 10.0.0.0 --- 10.255.255.255 172.16.0.0 --- 172.31.255.
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.
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.
2-2. Typical Applications The 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH implements 24 Fast Ethernet TP ports with auto MDIX and 2 Gigabit dual media ports with SFP for removable module supported comprehensive fiber types of connection, including LC, BiDi LC for SFP.

3. Operation of Web-based Management This chapter instructs you how to configure and manage the 24 FAST ETHERNET + 2 GIGABIT L2 MANAGED SWITCH through the web user interface it supports, to access and manage the 24 10/100Mbps TP + 2 Gigabit dual media ports with TP/SFP Fiber management Ethernet switch.
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.
3-1. Web Management Home Overview After you login, the switch shows you the system information as Fig. 3-2. This page is default and tells you the basic information of the system, including “Model Name”, “System Description”, “Location”, “Contact”, “Device Name”, “System Up Time”, “Current Time”, “BIOS Version”, “Firmware Version”, “Hardware-Mechanical Version”, “Serial Number”, “Host IP Address”, “Host MAC Address”, “Device Port”, “RAM Size” and “Flash Size”.

Device Port: Show all types and numbers of the port in the switch. RAM size: The size of the DRAM in this switch. Flash size: The size of the flash memory in this switch.
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.
IP address: Users can configure the IP settings and fill in new values if users set the DHCP function “Disable”. Then, click 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.
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.
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: 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 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.
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 Fig.
3-1-4. Account Configuration In this function, only administrator can create, modify or delete the username and password. Administrator can modify other guest identities’ password without confirming the password but it is necessary to modify the administrator-equivalent identity. Guest-equivalent identity can modify his password only. Please note that you must confirm administrator/guest identity in the field of Authorization in advance before configuring the username and password.
3-1-5. Management Security Through the management security configuration, the manager can do the strict setup to control the switch and limit the user to access this switch. The following rules are offered for the manager to manage the switch: Rule 1) : When no list exists, then it will accept all connections.
Function name: Management Security Configuration Function description: The switch offers Management Security Configuration function. With this function, the manager can easily control the mode that the user connects to the switch. According to the mode, users can be classified into two types: Those who are able to connect to the switch (Accept) and those who are unable to connect to the switch (Deny).
IP Range: The switch supports two kinds of options for managed valid IP Range, including “Any” and “Custom”. Default is “Any”. In case that ”Custom” had been chosen, you can assign effective IP range. The valid range is 0.0.0.0~255.255.255.255. Incoming Port: The switch supports two kinds of options for managed valid Port Range, including “Any” and “Custom”. Default is “Any”.
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.
Fig. 3-8 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 characters.
3-2. Port Configuration 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.

3-2-2. 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. Fig. 3-11 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, Speed/Duplex and Flow Control.
Speed/Duplex: Set the speed and duplex of the port. In speed, 10/100Mbps baud rate is available for Fast Ethernet, Gigabit module in port 25, 26. 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.
3-2-3. Port Description Port Description is applied to change the setting of each port. In this configuration function, you can give a name to each port. All of them are described in detail below. Fig. 3-12 Function name: Port Description Function description: It is used to set each port’s description. This human readable description can make the port management easier. Parameter description: Description: This field can enter up to 47 characters for the port description purpose. Default: .
3-2-5. Simple Counter The function of Simple Counter collects any information and provides the counting about the traffic of the port, no matter the packet is good or bad. In the Fig. 3-13, the window can show all ports’ counter information at the same time. Each data field has 20-digit long. If the counting is overflow, the counter will be reset and restart counting. The data is updated every time interval defined by the user. The valid range is 3 to 10 seconds.
Rx Packet: The counting number of the packet received. Tx Collision: Number of collisions transmitting frames experienced. Rx Error Packet: Number of bad packets received.
3-2-4. Detail Counter The function of Detail Counter collects any information and provides the counting about the traffic of the port, no matter the packet is good or bad. In the Fig. 3-14, the window can show only one port counter information at the same time. To see another port’s counter, you have to pull down the list of Select, then you will see the figures displayed about the port you had chosen. Each data field has 20-digit long.

Tx Broadcast Packets: Show the counting number of the transmitted broadcast packet. Tx Multicast Packets: Show the counting number of the transmitted multicast packet. Tx Pause Packets: Show the counting number of the transmitted pause packet. Rx FCS Errors: Number of bad FSC packets received.
3-3. SNMP Configuration Any Network Management System (NMS) running the Simple Network Management Protocol (SNMP) can manage the Managed devices equipped with SNMP agent, provided that the Management Information Base (MIB) is installed correctly on the managed devices. The SNMP is a protocol that is used to govern the transfer of information between SNMP manager and agent and traverses the Object Identity (OID) of the management Information Base (MIB), described in the form of SMI syntax.
Default SNMP function: Enable Default community name for GET: public Default community name for SET: private Default community name for Trap: public Default Set function: Enable Default trap host IP address: 0.0.0.0 Default port number: 162 Trap: In the switch, there are 6 trap hosts supported. Each of them has its own community name and IP address; is user-definable. To set up a trap host means to create a trap manager by assigning an IP address to host the trap message.
3-4. Loop Detection Looping will always occur when the switches are connected as a cycle and a switch transmits the packets that will go back to the transmitted switch. Loop Detection will prevent the looping from happening. Moreover, it could remove the looping phenomenon per port. In general, you can unplug the cable connection to stop the looping when a port causes the looping. The switch has powerful Looping Detection capability, which could cease the looping immediately. Fig.
looping detection. After enabling looping action, you should decide which port you would like to open loop detection capability. For example, you open the loop detection of port 1 as enable state. When the looping situation happens from port 1, Loop Detection will lock the port1’s ability. And then you will see that the “Current Status” of port 1 shows Locked. In port status function, you can see that the State of Port Configuration of port 1 is “Disabled”.
3-5. DHCP Boot The DHCP Boot function is used to spread the request broadcast packet into a bigger time frame to prevent the traffic congestion due to broadcast packets from many network devices which may seek its NMS, boot server, DHCP server and many connections predefined when the whole building or block lose the power and then reboot and recover.
3-6. IGMP Snooping The function, IGMP Snooping, is used to establish the multicast groups to forward the multicast packet to the member ports, and, in nature, avoids wasting the bandwidth while IP multicast packets are running over the network. This is because a switch that does not support IGMP or IGMP Snooping can not tell the multicast packet from the broadcast packet, so it can only treat them all as the broadcast packet.
Parameter description: IGMP snooping mode selection: The switch supports three kinds of IGMP Snooping status, including “Passive”, “Active” and “Disable”. Disable: Set “Disable” mode to disable IGMP Snooping function. Default: Disable Active: In Active mode, IGMP snooping switch will periodically issue the Membership Query message to all hosts attached to it and gather the Membership report message to update the database of the Multicast table.
Function name: Allowed Group Function description: The Allowed Group function allows the IGMP Snooping to set up the IP multicast table based on user’s specific conditions. IGMP report packets that meet the items you set up will be joined or formed the multicast group. Fig. 3-19 Parameter description: IP Range: The switch supports two kinds of options for managed valid IP range, including “Any” and “Custom”. Default is “Any”. In case that ”Custom” is chosen, you can assign effective IP range.
Add: A new entry of allowed group configuration can be created after the parameters as mentioned above had been setup and then press button. Edit: The existed entry also can be modified after pressing button. Delete: Remove the existed entry of allowed group configuration from the allowed group.
3-7. VLAN The switch supports Tag-based VLAN (802.1q) and Port-based VLAN. It supports 256 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. 3-7-1.
Symmetric Vlan: This is an Ingress Rule (Rule 1, The Ingress Filtering Rule 1 is “forward only packets with VID matching this port’s configured VID”.). For example, if port 1 receives a tagged packet with VID=100 (VLAN name=VLAN100), and if Symmetric-Vlan function is enabled, the switch will check if port 1 is a member of VLAN100. If yes, the received packet is forwarded; otherwise, the received packet is dropped.
Fig.
3-7-2. Tag-based Group Function name: Tag-based Group Configuration Function description: It shows the information of existed Tag-based VLAN Groups. You can also easily create, edit and delete a Tag-based VLAN group by pressing , and function buttons. User can add a new VLAN group by inputting a new VLAN name and VLAN ID after pressing button. Parameter description: VLAN Name: The name defined by administrator is associated with a VLAN group.
Add Group: Input the VLAN name, VID and then choose the member by ticking the check box beside the port No. to create a new Tag-based VLAN. As to the parameter of Untag, it stands for an egress rule of the port. If you tick the check box beside the port No., packets with this VID outgoing from this port will be untagged. Finally, press the button to have the setting taken effect. Fig.
3-7-3. PVID Function name: PVID Function description: In PVID 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 rule (Rule 2) to each port. The Ingress Filtering Rule 2 is “drop untagged frame”. While Rule 2 is enabled, the port will discard all Untagged-frames. Fig. 3-23 Parameter description: Port 1-26: Port number. PVID: This PVID range will be 1-4094.
It bases on 802.1p QoS and affects untagged packets. When the packets enter the switch, it would get the priority precedence according to your Default Priority setting and map to 802.1p priority setting in QoS function.

3-12. 802.1x Configuration 802.1x port-based network access control provides a method to restrict users to access network resources via authenticating user’s information. This restricts users from gaining access to the network resources through a 802.1x-enabled port without authentication. If a user wishes to touch the network through a port under 802.
The overview of operation flow is quite simple. When Supplicant PAE issues a request to Authenticator PAE, Authenticator and Supplicant exchanges authentication message. Then, Authenticator passes the request to RADIUS server to verify. Finally, RADIUS server replies if the request is granted or denied. While in the authentication process, the message packets, encapsulated by Extensible Authentication Protocol over LAN (EAPOL), are exchanged between an authenticator PAE and a supplicant PAE.
Authentication server C Fig. 3-41 Authenticator B Supplicant A The Figure shows the procedure of 802.1x authentication. There are steps for the login based on 802.1x port access control management. The protocol used in the right side is EAPOL and the left side is EAP. 113 1. At the initial stage, the supplicant A is unauthenticated and a port on switch acting as an authenticator is in unauthorized state. So the access is blocked in this stage. 2. Initiating a session.
8. If user ID and password is correct, the authentication server will send a Radius-Access-Accept to the authenticator. If not correct, the authentication server will send a Radius-Access-Reject. 9. When the authenticator PAE receives a Radius-Access-Accept, it will send an EAP-Success to the supplicant. At this time, the supplicant is authorized and the port connected to the supplicant and under 802.1x control is in the authorized state.
Only MultiHost 802.1X is the type of authentication supported in the switch. In this mode, for the devices connected to this port, once a supplicant is authorized, the devices connected to this port can access the network resource through this port. 802.1x Port-based Network Access Control function supported by the switch is little bit complex, for it just support basic Multihost mode, which can distinguish the device’s MAC address and it’s VID.
