2. Installation 2-1. Starting LGB1005A-R2 Up This section will give users a quick start for: - Hardware and Cable Installation - Management Station Installation - Software booting and configuration 2-1-1.
• 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.
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 LGB1005A-R2 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 of LGB1005A-R2 through the Serial RS232 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.
• 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.
2-1-4-2. Configuring the Management Agent of LGB1005A-R2 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. LGB1005A-R2 L2 Managed Switch Default IP Setting: IP = 192.168.1.1 Subnet Mask = 255.255.255.0 Default Gateway = 192.168.1.
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 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.
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 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 LGB1005A-R2 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.

3-1-2. 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. Guestequivalent 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.
3-1-3. 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. 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.
3-1-5. Loop Detection The loop detection is used to detect the presence of traffic. When switch receives packet’s(looping detection frame) MAC address the same 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. Fig.
3-1-6. Management Policy 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 lists exists, then it will accept all connections.

3-9. IP MAC 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 IP-MAC 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.

3-10. 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 802.1Xenabled port without authentication. If a user wishes to touch the network through a port under 802.
The overview of operation flow for the Fig. 3-53 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.
Authentication server C Authenticator B Fig. 3-54 Supplicant A The Fig. 3-55 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. 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 its VID.

3-11. Trunking Configuration The Port Trunking Configuration is used to configure the settings of Link Aggregation. You can bundle more than one port with the same speed, full duplex and the same MAC to be a single logical port, thus the logical port aggregates the bandwidth of these ports. This means you can apply your current Ethernet equipments to build the bandwidth aggregation.
Per Trunking Group supports a maximum of 12 ready member-ports. Please note that some decisions will automatically be made by the system while you are configuring your trunking ports. Some configuration examples are listed below: a) 12 ports have already used Static Trunk Group ID 1, the 13th port willing to use the same Static Trunk Group ID will be automatically set to use the “None” trunking method and its Group ID will turn to 0. This means the port won’t aggregate with other ports.
3-11-1.Port Function name: Trunk Port Setting/Status Function description: Port setting/status is used to configure the trunk property of each and every port in the switch system. Parameter description: Port: Port Number: 1-24 Method: This determines the method a port uses to aggregate with other ports. None: A port does not want to aggregate with any other port should choose this default setting. LACP: A port use LACP as its trunk method to get aggregated with other ports also using LACP.
Aggtr: Aggtr is an abbreviation of “aggregator”. Every port is also an aggregator, and its own aggregator ID is the same as its own Port No. We can regard an aggregator as a representative of a trunking group. Ports with same Group ID and using same trunking method will have the opportunity to aggregate to a particular aggregator port. This aggregator port is usually the port with the smallest Port No. within the trunking group.
3-11-2 Aggregator View Function name: Aggregator View Function description: To display the current port trunking information from the aggregator point of view. Parameter description: Aggregator: It shows the aggregator ID (from 1 to 24) of every port. In fact, every port is also an aggregator, and its own aggregator ID is the same as its own Port No..

A system ID is a 64-bit field comprising a 48-bit MAC Address and 16-bit priority value. The System Priority can be set by the user. Its range is from 1 to 65535.
3-12 STP Configuration The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, ensure that only one path is active between any two nodes on the network at a time. User can enable Spanning Tree Protocol on switch’s web management and then set up other advanced items. We recommend that you enable STP on all switches to ensure a single active path on the network. 3-12-1.
All bridges in the LAN will re-learn and determine which the root bridge is. Maximum Age time is assigned by root bridge in unit of seconds. Default is 20 seconds. Current Forward Delay: Show the current root bridge forward delay time. The value of Forward Delay time is set by root. The Forward Delay time is defined as the time spent from Listening state moved to Learning state or from Learning state moved to Forwarding state of a port in bridge. Hello Time: Show the current hello time of the root bridge.
3-12-2. Configuration The STP, Spanning Tree Protocol, actually includes RSTP. In the Spanning Tree Configuration, there are six parameters open for the user to configure as user’s idea.

Function name: STP Configuration Function description: User can set the following Spanning Tree parameters to control STP function enable/disable, select mode RSTP/STP and affect STP state machine behavior to send BPDU in this switch.
Forward Delay: You can set the root bridge forward delay time. This figure is set by root bridge only. The forward delay time is defined as the time spent from Listening state moved to Learning state and also from Learning state moved to Forwarding state of a port in bridge. The forward delay time contains two states, Listening state to Learning state and Learning state to Forwarding state. It assumes that forward delay time is 15 seconds, then total forward delay time will be 30 seconds.
3-12-3. STP Port Configuration Function name: STP Port Setting Function description: In the STP Port Setting, one item selection and five parameters settings are offered for user’s setup. User can disable and enable each port by selecting each Port Status item. User also can set “Path Cost” and “Priority” of each port by filling in the desired value and set “Admin Edge Port” and “Admin Point To Point” by selecting the desired item. Parameter description: Port Status: It displays the current state of a port.
802.1w RSTP recommended value: (Valid range: 1 – 200,000,000) 10 Mbps : 2,000,000 100 Mbps : 200,000 1 Gbps : 20,000 Default: 0 Priority: Priority here means Port Priority. Port Priority and Port Number are mixed to form the Port ID. Port IDs are often compared in order to determine which port of a bridge would become the Root Port. The range is 0 – 240. Default is 128. Admin Edge Port: If user selects “Yes”, this port will be an edge port.
M Check: Migration Check. It forces the port sending out an RSTP BPDU instead of a legacy STP BPDU at the next transmission. The only benefit of this operation is to make the port quickly get back to act as an RSTP port. Click button to send a RSTP BPDU from the port you specified. Fig.
3-13 MSTP The implementation of MSTP is according to IEEE 802.1Q 2005 Clause 13 – Multiple Spanning Tree Protocol. MSTP allows frames assigned to different VLANs to follow separate paths, each based on an independent Multiple Spanning Tree Instance (MSTI), within Multiple Spanning Tree (MST) Regions composed of LANs and or MST Bridges. Proper configuration of MSTP in an 802.1Q VLAN environment can ensure a loop-free data path for a group of vlans within an MSTI.

3-15. 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.
