Page 20: Switch Cascading In Topology
If more than two switches are connected in the same network, select one switch as Level 1 switch and connect all other switches to it at Level 2. Server/Host is recommended to connect to the Level 1 switch.
Page 21 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.
Page 22 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. VLAN3 members could not access VLAN1, VLAN2 and VLAN4. 4.
Page 23: Configuring The Management Agent
2-1-4. Configuring the Management Agent 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.
Page 24: Configuring The Management Agent Through The Serial Rs-232 Port
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 57.6k bps with 8 data bits, 1 stop bit, no parity check and no flow control.
Page 25 • Set IP Address, Subnet Mask and Default Gateway IP Address Please refer to Fig. 2-7 CLI Management for details about LevelOne’s 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 26: Configuring The Management Agent Through The Ethernet Port
IP address or to know the IP address of the switch. Then, follow the procedures listed below. 1. Set up a physical path between the configured the switch and a PC by a qualified UTP Cat. 5 cable with RJ-45 connector.
Page 27: Ip Address Assignment
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 28 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 29 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 30 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 31 Basically, it is a routing policy. The gateway setting is used for Trap Events Host only in the switch. For assigning an IP address to the switch, you just have to check what the IP address of the network will be connected with the switch. Use the same network address and append your host address to it.

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
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 0 0 1 in vlan-tagged field and VID equals 2 from the port 3 into the switch. We let the two kinds of packets be transmitted for port 1 until the port results in congestion. The result is that the packets will be dropped partially from the port 3 because the packets that belong to Low Priority.
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, 1 1 0 and 1 1 1.
Page 74 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, mail, FTP and news “L4 QoS Configuration and click <Apply> button, and then click <Advance >>>...
Page 75 Prioritize Streaming Audio/Video: Belong to the QoS in L4. Just tick the option button and press <Apply> button to have this function taken affect. 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 IP Diffserve Classification function, it can form total 64 (0~63) kinds of Traffic Class based on the arrangement of 6-bit field in DSCP of the IP packet. In the switch, user is allowed to set up these 64 kinds of Class that belong to High or Low Priority.
Page 78: Loop Detection
Detection willprevent the looping from happening. Moreover, it could remove the loopingphenomenon per port. In general, you can unplug the cable connection to stop thelooping when a port causes the looping. The switch has powerful Looping Detectioncapability, which could cease the looping immediately.
Page 79 Parameters description: State: Open the Loop Detection capability per port. The list has “Enable” and “Disable”. Default is “Disable”. Current Status: Show the looping status per port. It could be “Unlocked or Locked”. Default is “Unlocked”. When some port happens looping, it will show “Locked” Resume Action: Remove the looping status per port.
Page 80: Snmp Configuration
Basically, it is passive except issuing the trap information. The switch supports a switch to turn on or off the SNMP agent. If you set the field SNMP “Enable”, SNMP agent will be started up. All supported MIB OIDs, including RMON MIB, can be accessed via SNMP manager.
Page 81 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.
Page 82: Igmp Snooping
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 83 Passive: In Passive Snooping mode, the IGMP snooping will not periodically poll the hosts in the groups. The switch will send a Membership Query message to all hosts only when it has received a Membership Query message from a router.
Page 84 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. The valid range is 224.0.0.0~239.255.255.255.
Page 85 Add: A new entry of 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 86: Max. Packet Length
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.
Page 87: Dhcp Boot
At this moment, a bunch of switch or other network device on the LAN will try its best to find the server to get the services or try to set up the predefined links, they will issue many broadcast packets in the network.
Page 88: Vlan
Parameter description: VLAN Mode: Disable: Stop VLAN function on the switch. In this mode, no VLAN is applied to the switch. This is the default setting. Port-based: Port-based VLAN is defined by port. Any packet coming in or outgoing from any one port of a port-based VLAN will be accepted.
Page 89 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 90 2 members are formed. 23&24: Except Port 23 and Port 24, each port of the switch cannot transmit packets with each other. Each port groups a VLAN with Port 23 and Port 24, thus, total 22 groups consisting of 3 members are formed.
Page 91: Tag-Based Group
3-11-2. 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. User can add a new VLAN group by inputting a new VLAN name and VLAN ID.
Page 92 Add Group: Create a new Tag-based VLAN. Input the VLAN name as well as VID, configure the SYM-VLAN function and choose the member by ticking the check box beside the port No., then, press the <Apply> button to have the setting taken effect.
Page 93: Port-Based Group
3-11-3. Port-based Group Function name: Port-based Group Configuration Function description: It shows the information of the existed Port-based VLAN Groups. You can easily create, edit and delete a Port-based VLAN group by pressing <Add>, <Edit> and <Delete> function buttons. User can add a new VLAN group by inputting a new VLAN name.
Page 94 Add Group: Create a new Port-based VLAN. Input the VLAN name and choose the member by ticking the check box beside the port No., then, press the <Apply> button to have the setting taken effect. Delete Group: Just press the <Delete> button to remove the selected group entry from the Port-based group table.
Page 95: Tag Rule
For example, if port 1 receives a tagged packet with VID=100 (VLAN name=VLAN100), and if Rule 1 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.
Page 96 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 tag-out.
Page 97: Mac Table
3-12. 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 98 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 99 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 100 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 101 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 <Delete>...
Page 102 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 103 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 – 11 – 6B – 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.

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 105 A time period for announcement that all registered device is going to be de-registered. If someone still issues a new join, then a registration will be kept in the switch. Valid range: 1000-5000 unit time, Default: 1000 unit time. Default Applicant Mode: The mode here means the type of participant.
Page 106 GVRP PDU. There are two modes, disable and enable, provided for the user’s choice. Disabled: In this mode, the switch dynamic VLAN will be created when this port received GVRP PDU. The default setting is Normal. Enabled: In this mode, the switch does not create dynamic VLAN when this port received GVRP PDU.
Page 107 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. 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 108 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 109 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.

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. The default setting of Spanning Tree Protocol is “Disable”. Parameter description: Spanning Tree Protocol: Set 802.1W Rapid STP function Enable / Disable.
Page 113 Two options are offered for the user’s choosing STP algorithm. One is RSTP and the other is STP. If STP is chosen, RSTP will run as a legacy STP. The switch supports RSTP (802.1w) which is backward compatible with STP (802.1d).
Page 114: Stp Port Configuration
Root Port more possibly. Configured Path Cost: The range is 0 – 200,000,000. In the switch, if path cost is set to be zero, the STP will get the recommended value resulted from auto-negotiation of the link accordingly and display this value in the field of Path Cost Status.
Page 115 802.1w RSTP recommended value: (Valid range: 1 – 200,000,000) 10 Mbps : 2,000,000 100 Mbps : 200,000 1 Gbps 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.
Page 116 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 <M Check>...
Page 117: Trunking Configuration
As to system restrictions about the port aggregation function on the switch, In the management point of view, the switch supports maximum 8 trunk groups for LACP and additional 8 trunk groups for Static Trunk. But in the system capability view, only 8 “real trunked”...
Page 118 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”...
Page 119 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 120 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 121 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..

3-16. 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 125 PC A, then, is allowed to access B and C via the switch. If there are two switches directly connected together instead of single one, for the link connecting two switches, it may have to act two port roles at the end of the link: authenticator and supplicant, because the traffic is bi-directional.
Page 126 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. So the access is blocked in this stage.
Page 127 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 128 Only Normal 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.
