Page 21: Configuring The Management Agent Of 24 Gigabit L2 Managed Switch
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.
Page 22 • 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.
Page 23: Configuring The Management Agent Of 24 Gigabit L2 Managed Switch Through The Ethernet Port
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.
Page 24: Ip Address Assignment
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.
Page 25 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.
Page 26 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.
Page 27 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.
Page 28 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.

Page 65: Mirror
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.
Page 66: Bandwidth Management
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.
Page 67 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.
Page 68: Qos(Quality Of Service) Configuration
3-5. QoS(Quality of Service) Configuration offers powerful 5 kinds of QoS functions. There are Per Port switch 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.
Page 69 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.
Page 70 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.
Page 71 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.
Page 72 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.
Page 73 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.

Then, click Advance >>> button set up Special TCP/UDP port for QoS. Prioritize Databases (Oracle, IBM DB2, SQL, Microsoft): Belong to the QoS in L4.
Page 76 Advanced Mode Fig. 3-21 Simple Mode Fig. 3-22 Simple Mode: Press <Simple<<> button is to return to the screen that all L4 port number will disappear (See Fig. 3-22).
Page 77 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.
Page 78: Snmp Configuration
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.
Page 79 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;...
Page 80: Igmp Snooping
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.
Page 81 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.
Page 82 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.
Page 83 Add: A new entry of configuration can be created after the allowed group parameters as mentioned above had been setup and then press <Add> button. Edit: The existed entry also can be modified after pressing <Edit> button. Delete: Remove the existed entry of allowed group configuration from the allowed group.
Page 84: Max. Packet Length
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.
Page 85: Dhcp Boot
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.
Page 86: Vlan
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.
Page 87 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.
Page 88 Up-link Port: This function is enabled only when metro mode is chosen in VLAN mode. 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.
Page 89: Tag-Based Group
3-10-2. 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 <Add>, <Edit> and <Delete> function buttons.

3-10-4. Tag Rule Function name: Tag Rule 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.
Page 95 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.
Page 96: Mac Table
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.
Page 97 Port: The port that exists in the searched MAC Entry. VID: VLAN Group that MAC Entry exists. State: Display the method that this MAC Entry is built. It may show “Dynamic MAC” or “Static MAC”. Fig. 3-38...
Page 98 Function Name: MAC Table Maintenance Function Description: This function can allow the user to set up the processing mechanism of MAC Table. 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.
Page 99 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.
Page 100 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.
Page 101 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.
Page 102 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.
Page 103: Gvrp Configuration
3-12. GVRP Configuration GVRP is an application based on Generic Attribute Registration Protocol (GARP), mainly used to automatically and dynamically maintain the group membership information of the VLANs. The GVRP offers the function providing the VLAN registration service through a GARP application. It makes use of GARP Information Declaration (GID) to maintain the ports associated with their attribute database and GARP Information Propagation (GIP) to communicate among switches and end stations.
Page 104 Function name: GVRP Config Function description: In the function of GVRP Config, it is used to configure each port’s GVRP operation mode, in which there are seven parameters needed to be configured described below. Parameter description: GVRP State Setting: This function is simply to let you enable or disable GVRP function. You can pull down the list and click the <Downward>...
Page 105 Normal: It is Normal Registration. The Registrar responds normally to incoming GARP messages. The default setting is Normal. Fixed: It is Registration Fixed. The Registrar ignores all GARP messages, and all members remain in the registered (IN) state. Forbidden: It is Registration Forbidden. The Registrar ignores all GARP messages, and all members remain in the unregistered (EMPTY) state.
Page 106 Function name: GVRP Counter Function description: All GVRP counters are mainly divided into Received and Transmitted two categories to let you monitor the GVRP actions. Actually, they are GARP packets. Fig. 3-44 Parameter description: Received: Total GVRP Packets: Total GVRP BPDU is received by the GVRP application. Invalid GVRP Packets: Number of invalid GARP BPDU is received by the GARP application.
Page 107 LeaveEmpty Message Packets: Number of GARP BPDU with Leave Empty message is received by the GARP application. Empty Message Packets: Number of GARP BPDU with Empty message is received by the GARP application. Transmitted: Total GVRP Packets: Total GARP BPDU is transmitted by the GVRP application. Invalid GVRP Packets: Number of invalid GARP BPDU is transmitted by the GVRP application.
Page 108 Function name: GVRP Group Information Function description: To show the dynamic group member and their information. Parameter description: VID: VLAN identifier. When GVRP group creates, each dynamic VLAN group owns its VID. Valid range is 1 ~ 4094. Member Port: Those are the members belonging to the same dynamic VLAN group.
Page 109: Stp Configuration
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.

Page 116: Trunking Configuration
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.
Page 117 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: 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”...
Page 118 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.
Page 119 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.
Page 120 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..

Page 123: Configuration
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 802.1X- enabled port without authentication. If a user wishes to touch the network through a port under 802.1X control, he (she) must firstly input his (her) account name for authentication and waits for gaining authorization before sending or receiving any packets from a 802.1X-enabled port.
Page 124 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.
Page 125 Authentication server Fig. 3-54 Authenticator 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. At the initial stage, the supplicant A is unauthenticated and a port on switch acting as an authenticator is in unauthorized state.
Page 126 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. 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.
Page 127 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.
Page 128 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.
