2. Installation 2-1. Starting SNMP-GSH2402 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.
• 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 Gigabit L2 Managed Switch 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.
2-1-4-1. Configuring the Management Agent of 24 Gigabit L2 Managed Switch 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 the ex-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 of 24 Gigabit L2 Managed Switch 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. 24 Gigabit 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 24 Gigabit L2 Managed Switch implements 24 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.
Fig. 2-14 Peer-to-peer Network Connection Fig.
3. Operation of Web-based Management This chapter instructs you how to configure and manage the switch through the web user interface it supports, to access and manage the 22-Port 10/100/1000Mbps TP and 2-Port Gigabit 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”.
• The Information of Page Layout ⎯ On the top side, it shows the front panel of the switch. In the front panel, the linked ports will display green; as to the ports, which are link off, they will be dark. For the optional modules, the slot will show only a cover plate if no module exists and will show a module if a module is present. The image of module depends on the one you inserted. The same, if disconnected, the port will show just dark, if linked, green.

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.
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.
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 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.
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 assigned 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.

Mon3(RX PWR): Show the receiver power of SFP module.
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. 3-12 Function name: Port Configuration Function description: It is used to set each port’s operation mode. The switch supports 3 parameters for each port. They are state, mode and flow control. Parameter description: State: Set the communication capability of the port is Enabled or Disabled.
Mode: Set the speed and duplex of the port. In speed, if the media is 1Gbps fiber, it is always 1000Mbps and the duplex is full only. If the media is TP, the Speed/Duplex is comprised of the combination of speed mode, 10/100/1000Mbps, and duplex mode, full duplex and half duplex. The following table summarized the function the media supports. Media type 1000M TP 1000M Fiber NWay ON/OFF ON/OFF Speed 10/100/1000M 1000M Duplex Full for all, Half for 10/100 Full In Auto-negotiation mode, no default value.
3-2-3. 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.
56
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.
Rx Low Priority Packets: Number of Rx packets classified as low priority. Rx Broadcast: Show the counting number of the received broadcast packet. Rx Multicast: Show the counting number of the received multicast packet. Tx Packets: The counting number of the packet transmitted. TX Octets: Total transmitted bytes. Tx High Priority Packets: Number of Tx packets classified as high priority. Tx Low Priority Packets: Number of Tx packets classified as low priority.
Tx 65-127 Bytes: Number of 65 ~ 126-byte frames in good and bad packets transmitted. Tx 128-255 Bytes: Number of 127 ~ 255-byte frames in good and bad packets transmitted. Tx 256-511 Bytes: Number of 256 ~ 511-byte frames in good and bad packets transmitted. Tx 512-1023 Bytes: Number of 512 ~ 1023-byte frames in good and bad packets transmitted. Tx 1024-Bytes: Number of 1024-max_length-byte frames in good and bad packets transmitted.
3-3. Mirror Function name: Mirror Configuration Function description: Mirror Configuration is to monitor the traffic of the network. For example, we assume that Port A and Port B are Monitoring Port and Monitored Port respectively, thus, the traffic received by Port B will be copied to Port A for monitoring. Note: When configuring the mirror function, you should avoid setting a port to be a sniffer port and aggregated port at the same time. It will cause something wrong.
3-4. Bandwidth Management Function name: Bandwidth Management Function description: Bandwidth Management function is used to set up the limit of Ingress and Egress bandwidth for each port. Note: Each port of the switch owns 16KB packet buffer. The packet buffer size will be reduced when the bandwidth rate limitation is enabled, which may cause that jumbo frame cannot be forwarded. Please avoid enabling jumbo frame and bandwidth rating functions at the same time. Fig.
Broadcast & Multicasat for Ingress Rate Limiting (Policing): Set up the limit of Ingress bandwidth for the port you choose. Incoming traffic will be discarded if the rate exceeds the value you set up in Data Rate field. The format of the packet limits to broadcast and multicast. Valid range is 0~1000. All Traffic for Egress Rate Limiting(Shaping): Set up the limit of Egress bandwidth for the port you choose. Packet transmission will be delayed if the rate exceeds the value you set up in Data Rate field.
3-5. QoS(Quality of Service) Configuration The switch offers powerful 5 kinds of QoS functions. There are Per Port Priority that you can assign each port to different precedence, VLAN Tag priority that can make precedence of 8 priorities, IP TOS Classification, IP TCP/UDP Port Classification and IP DiffServe Classification. In Quality of Service (QoS) Configuration, there is one option named” Default Class”.
Function name: Per Port Priority Function description: We can assign QoS Priority, including High and Low for each port. For example, if we transmit IP packets from Port 2 and Port 3 at the speed of 1Gbps to Port 1, and set the Class of Port 2 as High and Port 3 as Low, then the packets of Port 3 will be dropped when the congestion happens because Port 2 owns higher precedence of transmitting packets.
Function name: VLAN Tag Priority Function description: In vlan tag, there are 3 bits belonging to priority. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0, 1 1 1. We can set High priority or Low priority for each traffic class. For instance, if we let VLAN-tagged priority 0 0 0 be high priority and VLAN-tagged priority 0 0 1 be Low Priority, and then make port 1, 2, 3 be in the vlan 2.
Bit 0, Bit 1, Bit 2: According to the arrangement of VLAN-tagged priority, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0 and 1 1 1. Class: 8 kinds of traffic as mentioned above, user can set up High Priority or Low Priority for each port respectively.
Function name: IP ToS Classification Function description: Another QoS function is the application of Layer 3 on network framework. We focus on TOS field of IP header. There are three bits in TOS field. We means bit 5~7 of TOS field that we will use. According to these 3 bits, we could arrange 8 traffics –0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0, 1 1 1. As long as we change bit 5~7 of TOS field of IP header, we will create the 8 traffic packets we meant before.
Bit 0, Bit 1, Bit 2: According to the arrangement of Bit 5 ~ Bit 7 in TOS Field of IP Header, it can form 8 kinds of traffics, including 0 0 0, 0 0 1, 0 1 0, 0 1 1, 1 0 0, 1 0 1, 1 1 0 and 1 1 1. Class: 8 kinds of traffic as mentioned above, user can set up High Priority or Low Priority for each port respectively.
Function name: IP TCP/UDP Port Classification Function description: In L4 QoS Configuration, you can enter one of these special network transmission events, for example we use” Down prioritize web browsing, e-mail, FTP and news “L4 QoS Configuration and click button, and then click >> button.
Prioritize Streaming Audio/Video: Belong to the QoS in L4. Just tick the option button and press button to have this function taken affect. Then, click >> button set up Special TCP/UDP port for QoS. Prioritize Databases (Oracle, IBM DB2, SQL, Microsoft): Belong to the QoS in L4. Just tick the option button and press button to have this function taken affect. Then, click >> button to set up Special TCP/UDP port for QoS.
Fig. 3-21 Advanced Mode Fig. 3-22 Simple Mode Simple Mode: Press button is to return to the screen that all L4 port number will disappear (See Fig. 3-22).
Function name: IP Diffserv Classification Function description: In the late 1990s, the IETF redefined the meaning of the 8-bit SERVICE TYPE field to accommodate a set of differentiated services (DS). Under the differentiated services interpretation, the first six bits comprise a codepoint, which is sometimes abbreviated DSCP, and the last two bits are left unused.
3-6. 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.
3-7. 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. 3-26 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” had been chosen, you can assigned 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.
3-8. Max. Packet Length Function name: Max. Packet Length Function description: The switch is capable of dealing with 9k Jumbo Frames, which suits the transmission for a large amount of data in the network environment. Parameter description: Jumbo Frame(bytes): Set up the maximum length of the packet that each port of the switch can accept. Maximum length can be up to 1532 bytes or 9216 bytes. The default is 1532 bytes. Fig.
3-9. 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.
3-10. VLAN The switch supports Tag-based VLAN (802.1q) and Port-based VLAN. Support 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. 3-10-1.
Metro Mode: The Metro Mode is a quick configuration VLAN environment method on Port-based VLAN. It will create 22 or 23 Port-based VLAN groups. Double-tag: 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 Tag-based VLAN. So, the incoming packets with tag will become the double-tag ones. Fig.
Up-link Port: This function is enabled only when metro mode is chosen in VLAN mode. 23: Except Port 23, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 23, thus, total 23 groups consisting of 2 members are formed. 24: Except Port 24, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 24, thus, total 23 groups consisting of 2 members are formed.

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”.
Role: 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.
3-11. MAC Table MAC Table Configuration gathers many functions, including MAC Table Information, MAC Table Maintenance, Static Forward, Static Filter and MAC Alias, which cannot be categorized to some function type. They are described below. Function name: MAC Table Information Function Description: Display the static or dynamic learning MAC entry and the state for the selected port. Parameter description: Port: Select the port you would like to inquire.

An idle MAC address exceeding MAC Address Age-out Time will be removed from the MAC Table. The range of Age-out Time is 10-65535 seconds, and the setup of this time will have no effect on static MAC addresses. Parameter description: Aging Time: Delete a MAC address idling for a period of time from the MAC Table, which will not affect static MAC address.
Function Name: Static Forward Function Description: Static Forward is a function that allows the user in the static forward table to access a specified port of the switch. Static Forward table associated with a specified port of a switch is set up by manually inputting MAC address and its alias name. When a MAC address is assigned to a specific port, all of the switch’s traffics sent to this MAC address will be forwarded to this port.
Function name: Static Filter Function Description: Static Filter is a function that denies the packet forwarding if the packet’s MAC Address is listed in the filtering Static Filter table. User can very easily maintain the table by filling in MAC Address, VID (VLAN ID) and Alias fields individually. User also can delete the existed entry by clicking button. Parameter description: MAC: It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens.
Function name: MAC Alias Function description: MAC Alias function is used to let you assign MAC address a plain English name. This will help you tell which MAC address belongs to which user in the illegal access report. At the initial time, it shows all pairs of the existed alias name and MAC address. There are three MAC alias functions in this function folder, including MAC Alias Add, MAC Alias Edit and MAC Alias Delete.
Parameter description: MAC Address: It is a six-byte long Ethernet hardware address and usually expressed by hex and separated by hyphens. For example, 00 – 40 - C7 - D6 – 00 - 01 Alias: MAC alias name you assign. Note: If there are too many MAC addresses learned in the table, we recommend you inputting the MAC address and alias name directly.

3-13. 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. 3-13-1.
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.
3-13-2. STP 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.

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.
3-14. 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.
Function name: 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: 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.
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..

Function name: LACP System Priority Function description: It is used to set the priority part of the LACP system ID. LACP will only aggregate together the ports whose peer link partners are all on a single system. Each system supports LACP will be assigned a globally unique System Identifier for this purpose. 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. Default: 32768 Fig.
3-15. 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 Fig. 3-54 Authenticator B 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.
Function name: 802.1X State Setting Function description: This function is used to configure the global parameters for RADIUS authentication in 802.1X port security application.
