10 2.1 General Description The Gigabyte GN-GSV2401M is a powerful, high-performance, Fast Ethernet switching hub, which acts as traffic controller for 24 local routes and 2 highways to connect your networks to other outside networks. With all 24 ports capable of 10 or 100 Mbps auto-negotiation operation (NWay) and 2 Gigabit Ethernet uplink ports, the switching hub can automatically negotiate with the connected partners for the network speed and duplex mode. It is ideal for micro-segmenting large networks into smaller, connected subnets for improved performance, enabling bandwidth-demanding multimedia, imaging and database applications. Moreover, the 10/100Mbps auto-sensing ability provides an easy way to migrate 10Mbps to 100 Mbps network with ease. Compared to the shared 10Mbps or 100Mbps networks, the switching hub delivers a dedicated 10/100Mbps connection to every attached client with no bandwidth congestion issues and the most cost-effective way to invest in your network s performance in the long run. Store-and-forward switching mode guarantees low latency, plus eliminates all network errors, including runt and CRC error packets. To work under fullduplex mode, transmission and reception of the frames can occur simultaneously without causing collisions, as well as doubling the network bandwidth. The switching hub is plug-and-play without needing any software to configure, and is also fully compliant with all kinds of network protocols. Moreover, the abundant diagnostic LEDs on the front-panel provide the operating status of individual ports and the entire system. 5

24 Advanced Miscellaneous Setting MAC Address Age-out Time Type the number of seconds that an inactive MAC address remains in the switch's address table. The valid range is 300~765 seconds. Default is 300 seconds. Max bridge transmit delay bound control Limit the packets queuing time in switch. If enable, the packets queued exceed will be drop. This valid value are 1sec, 2 sec, 4 sec and off. Enable Low Queue Delay Bound Limit the low priority packets queuing time in switch. If the low priority packet stays in switch exceed Max Delay Time, it will be sent. The valid range is 1~255 ms. NOTE: Make sure of Max bridge transit delay bound control is enabled before enable Delay Bound, because Enable Delay Bound must be work under Max bridge transit delay bound control is enabled situation. Broadcast Storm Filter To configure broadcast storm control, enable it and set the upper threshold for individual ports. The threshold is the percentage of the 19

25 port's total bandwidth used by broadcast traffic. When broadcast traffic for a port rises above the threshold you set, broadcast storm control becomes active. The valid threshold value are 5%, 10%, 15%, 20%, 25% and off. Priority Queue Service Settings First Come First Service The sequence of packets sent is depend on arrive order. All High before Low The high priority packets sent before low priority packets. WRR Weighted Round Robin. Select the preference given to packets in the switch's high-priority queue. These options represent the number of high priority packets sent before one low priority packet is sent. For example, 5 High : 2 Low means that the switch sends 5 high priority packets before sending 2 low priority packet. Qos Policy:High Priorit Levels 0~7 priority level can map to high or low queue. 20

26 Misc Config Collisions Retry Forever Disable In half duplex, if happen collision will retry 48 times and then drop frame. Enable In half duplex, if happen collision will retry forever. Hash Algorithm Under this option two settings are possible: CRC-Hash or DirectMap. The default value is CRC-Hash. IFG Compensation It means Interframe Gap (96 bits) compensation between two continue frames according to IEEE 802.3ad. Enable the IFG compensation will improve the collision case, Disable IFG compensation might get more throughput, but can't improve the collision case x Protocol Enable or disable 802.1x protocol. 21

27 Console Port Info Console is a standard UART interface to communicate with Serial Port. User can use windows HyperTerminal program to link the switch. Connect To->Configure Bits per seconds: 9600 Data bits: 8 Parity: none Stop Bits: 1 Flow control: none 22

28 Port Controls The Port Controls allows you to change every port status. State User can disable or enable this port control. Auto Negotiation User can set auto negotiation mode is Auto, Nway (specify the speed/duplex on this port and enable auto-negotiation), Force of per port. Speed User can set 100Mbps or 10Mbps speed on Port1~Port24 and set 1000Mbps, 100Mbps or 10Mbps speed on Port25~Port26 (depend on module card mode). Duplex User can set full-duplex or half-duplex mode of per port. Flows control: Full User can set flow control function is enable or disable in full mode. Half User can set backpressure is enable or disable in half mode. Rate Control VT6526, port1 ~ port 24, supports by-port ingress and egress rate control. For example, assume port 1 is 10Mbps, users can set it s effective egress rate is 1Mbps, ingress rate is 500Kbps. VT6526 will perform flow control or backpressure 23

29 to confine the ingress rate to meet the specified rate. Ingress Type the port effective ingress rate. The valid range is 0 ~ The unit is 100K 0: disable rate control. 1 ~ 1000: valid rate value Egress Type the port effective egress rate. The valid range is 0~1000. The unit is 100K. 0: disable rate control. 1 ~ 1000: valid rate value. Priority This static priority based on port, if you set the port is high priority, income frame from this port always high priority frame. Port Security A port in security mode will be locked without permission of address learning. Only the incoming packets with SMAC already existing in the address table can be forwarded normally. User can disable the port from learning any new MAC addresses, then use the static MAC addresses screen to define a list of MAC addresses that can use the secure port. Enter the desired settings and then click Apply button to save the new settings to the switch. 24

30 Trunking The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems on a link to allow their Link Aggregation Control instances to reach agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. In conclusion, Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refers to IEEE 802.3ad. Aggregator Setting System Priority A value used to identify the active LACP. The switch with the lowest value has the highest priority and is selected as the active LACP. Group ID There are seven trunk groups to provided configure. Choose the "group id" and click "Get". LACP If enable, the group is LACP static trunking group. If disable, the group is local static trunking group. All ports support LACP dynamic trunking group. If connecting to the device that also supports LACP, the LACP dynamic trunking group will be created automatically. 25

31 Work ports Allow max four ports can be aggregated at the same time. If LACP static trunking group, the exceed ports is standby and able to aggregate if work ports fail. If local static trunking group, the number must be as same as the group member ports. Select the ports to join the trunking group. Allow max four ports can be aggregated at the same time. If LACP enable, you can configure LACP Active/Passive status in each ports on State Activity page. Enter the desired settings and then click Apply button to save the new settings to the switch. Aggregator Information When you are setting LACP aggregator, you can see relation information in here. This page is no group active. LACP don t working. 26

32 This page is Static Trunking groups. This page is Actor and Partner trunking one group. 27

33 State Activity Active (select) The port automatically sends LACP protocol packets. Passive (no select) The port does not automatically sends LACP protocol packets, and responds only if it receives LACP protocol packets from the opposite device. 1. A link having either two active LACP ports or one active port can perform dynamic LACP trunking. A link has two passive LACP ports will not perform dynamic LACP trunking because both ports are waiting for and LACP protocol packet from the opposite device. 2. If you are active LACP s actor, when you are select trunking port, the active status will be created automatically. 28

34 Filter Database Forwarding and Filtering The GN-GSV2401M support IP multicast, you can enable IGMP protocol on web management s switch setting advanced page, then display the IGMP snooping information in this page, you can view difference multicast group,vid and member port in here, IP multicast addresses range from through The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the switch. IGMP have three fundamental types of message as follows: Message Description Query A message sent from the querier (IGMP router or switch) asking for a response from each host belonging to the multicast group. Report A message sent by a host to the querier to indicate that the host wants to be or is a member of a given group indicated in the report message. Leave Group A message sent by a host to the querier to indicate that the host has quit to be a member of a specific multicast group. 29

35 Static MAC Addresses When you add a static MAC address, it remains in the switch's address table, regardless of whether the device is physically connected to the switch. This saves the switch from having to re-learn a device's MAC address when the disconnected or powered-off device is active on the network again. 1. In the MAC address box, enter the MAC address to and from which the port should permanently forward traffic, regardless of the device s network activity. 2. In the Port Number box, enter a port number. 3. If tag-based (IEEE 802.1Q) VLANs are set up on the switch, static addresses are associated with individual VLANs. Type the VID (tag-based VLANs) to associate with the MAC address. 4. Click add. 30

36 MAC Filtering MAC address filtering allows the switch to drop unwanted traffic. Traffic is filtered based on the destination addresses. 1. In the MAC Address box, enter the MAC address that wants to filter. 2. If tag-based (802.1Q) VLAN are set up on the switch, in the VLAN ID box, type the VID to associate with the MAC address. 3. Click the Add. 4. Choose the MAC address that you want to delete and then click the Delete. 31

37 VLAN Configuration A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network devices are still plug into the same switch physically. The GN-GSV2401M support port-based, 802.1Q (tagged-based) and protocol-base VLAN in web management page. In the default configuration,vlan support is disable. NOTE: Change VLAN mode for every time, you have to reboot the switch for valid value. Support Port-based VLAN Packets can go among only members of the same VLAN group. Note all unselected ports are treated as belonging to another single VLAN. If the port-based VLAN enabled, the VLAN-tagging is ignored. 32

38 Support Tag-based VLAN (IEEE 802.1Q VLAN) Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a tag into the Ethernet frames. Tag contains a VLAN Identifier (VID) that indicates the VLAN numbers. Support Protocol-based VLAN In order for an end station to send packets to different VLANs, it itself has to be either capable of tagging packets it sends with VLAN tags or attached to a VLAN-aware bridge that is capable of classifying and tagging the packet with different VLAN ID based on not only default PVID but also other information about the packet, such as the protocol. GN-GSV2401M will support protocol-based VLAN classification by means of both built-in knowledge of layer 2 packet formats used by selected popular protocols, such as Novell IPX and AppleTalk s EtherTalk, and some degree of programmable protocol matching capability. Port-based VLAN 1. Click Add to create a new VLAN group. 2. Enter the VLAN name, group ID and select the members for the new VLAN. 3. Click Apply. 4. If there are many groups that over the limit of one page, you can click the 33

39 NextPage to view other VLAN groups. NOTE: If the trunk groups exist, you can see it (ex:trk1,trk2..) in select menu of ports, and you can configure it is the member of the VLAN or not Q VLAN User can create Tag-based VLAN, and enable or disable GVRP protocol. There are 256 VLAN groups to provide configure. Enable 802.1Q VLAN, the all ports on the switch belong to default VLAN, VID is 1. The default VLAN can t be delete. GVRP (GARP [Generic Attribute Registration Protocol] VLAN Registration Protocol) GVRP allows automatic VLAN configuration between the switch and nodes. If the switch is connected to a device with GVRP enabled, you can send a GVRP request using the VID of a VLAN defined on the switch, the switch will automatically add that device to the existing VLAN. Basic Create a VLAN and add tagged member ports to it. From the main Tag-based (IEEE 802.1Q) VLAN page, click Basic Settings. 1. Type a name for the new VLAN. 2. Type a VID (between ). The default is Choose the protocol type. 34

40 4. From the Available ports box, select ports to add to the switch and click Add >>. If the trunk groups exist, you can see it in here (ex:trk1,trk2 ), and you can configure it is the member of the VLAN or not. 5. Click Next. Then you can view the page as follow. 6. Tag: outgoing frames with VLAN-Tagged. Untag: outgoing frames without VLAN-Tagged. Port VID Configure port VID settings From the main Tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings. 35

41 Port VID (PVID) Set the port VLAN ID that will be assigned to untagged traffic on a given port. This feature is useful for accommodating devices that you want to participate in the VLAN but that don t support tagging. Each port allows user to set one PVID, the range is 1~255, default PVID is 1. The PVID must as same as the VLAN ID that the port belong to VLAN group, or the untagged traffic will be dropped. Ingress Filtering Ingress filtering lets frames belonging to a specific VLAN to be forwarded if the port belongs to that VLAN. GN-GSV2401M have two ingress filtering rule as follows: Ingress Filtering Rule 1 Forward only packets with VID matching this port's configured VID. Ingress Filtering Rule 2 Drop Untagged Frame. 36

42 Spanning Tree The Spanning-Tree Protocol (STP) is a standardized method (IEEE 802.1D ) for avoiding loops in switched networks. When STP enabled, to ensure that only one path at a time is active between any two nodes on the network. You can enable Spanning-Tree Protocol on web management s switch setting advanced item, select enable Spanning-Tree protocol. We are recommended that you enable STP on all switches ensures a single active path on the network. System Configuration Configuration Spanning Tree Parameters You can setting new value for STP parameter, then click Apply button to modify. Priority A value used to identify the root bridge. The bridge with the lowest value has the highest priority and is selected as the root.

STP Port Status You can view spanning tree status about the switch. 39

45 Port Sniffer The Port Sniffer is a method for monitor traffic in switched networks. Traffic through ports can be monitored by one specific port. That is, traffic goes in or out monitored ports will be duplicated into sniffer port. Roving Analysis State Set sniffer mode: Disable\Rx\Tx\Both. Analysis Port It s mean sniffer port can be used to see all monitor port traffic. You can connect sniffer port to lan analysier or netxray. Monitored Port All monitor port traffic will be copied to sinffer port. You can select max 25 monitor ports in the switch. User can choose which port want to monitored in only one sniffer mode. If you want to disable the function, you must select monitor port to none. 40

46 SNMP Any Network Management running the simple Network Management Protocol (SNMP) can management the switch, provided the Management Information Base (MIB) is installed correctly on the management station. The SNMP is a Protocol that governs the transfer of information between management and agent. The GN-GSV2401M support SNMP V1.

Ports can be combined to create high speed trunks. Select VLAN Configuration from the Main Menu and press Enter. 62

68 There are two most popular VLAN implementation, IEEE 802.1q Tagged VLAN and Port-based VLAN. GN-GSV2401M supports both VLAN implementation. The biggest difference between both VLAN implementations is Tagged VLAN can cross Layer-2 switch but Port-based VLAN can not. IEEE802.1q VLAN IEEE 802 Local Area Networks (LANs) of all types may be connected together with Media Access Control (MAC) Bridges, as specified in ISO/IEC This standard defines the operation of Virtual LAN (VLAN) Bridges that permit the definition, operation and administration of Virtual LAN topologies within a Bridged LAN infrastructure. There are two key components to understanding IEEE 802.1Q VLANs - Port VLAN ID numbers (PVID) and VLAN ID numbers (VID). Although both variables are assigned to a switch port, there are important differences between them. For instance, a user can only assign one PVID to each switch port. When packets have to be forwarded to another switch port or somewhere else on the network, the PVID defines the relevant VLAN recipient. On the other hand, a user can define a port as a member of multiple VLANs (VIDs) thus allowing the connected segment to receive packets from many VLANs on the network. These two variables control a port s ability to transmit and receive VLAN traffic. The difference between them provides network segmentation, while still allowing resources to be shared across more than one VLAN. Take for example a packet that is transmitted by a machine on Port 1 that is a member of VLAN 2 and has the Port VLAN ID number 2 (PVID=2). If the destination lies on another port (found through a normal forwarding table lookup), the switch then looks to see if the other port (Port 10) is a member of VLAN 2 (and can therefore receive VLAN 2 packets). If port 10 is not a member of VLAN 2, then the packet will be dropped by the switch and will not reach it s destination. If Port 10 is a member of VLAN 2, the packet will go through. This selective forwarding feature based on VLAN criteria is how VLANs segment networks. The key point being that Port 1 will only transmit on VLAN 2, because it s Port VLAN ID number is 2 (PVID=2). 63

69 VLAN Configuration You can assign the PVID for any ports in a domain. PVID (Port VID : 1~255) Type the PVID. NonMember Drop It matches that Ingress Filtering Rule 1 on web. Forward only packets with VID matching this port s configured VID. Press Space key to choose forward or drop the frame that VID not matching this port s configured VID. UnTagged Drop It matches that Ingress Filtering Rule 2 on web. Drop untagged frame. Press Space key to choose drop or forward the untagged frame. 64

70 Create a VLAN Group Enter a VLAN Name and a VLAN ID, and then you can configure the VLAN tagging which indicates whether or not VLAN tags will be included on frames passing through this port. Edit/Delete a VLAN Group You can modify or delete the settings for an existing VLAN. 65

71 Port-Based VLAN Port-based VLANs are VLANs where the packet forwarding decision is based on the destination MAC address and its associated port. You must define outgoing ports allowed for each port when using port-based VLANs. Note that VLAN only governs the outgoing traffic, in the other word, it is unidirectional. Therefore, if you wish to allow two subscriber ports to talk to each other, e.g., between conference rooms in a hotel, you must define the egress (outgoing port) for both ports. An egress port is an outgoing port, that is, a port through which a data packet leaves. VLAN Configuration 66

72 Create a VLAN Group Up to 26 port-based VLAN groups can be designated for the GN-GSV2401M. Individual ports can exit in two or more VLANs simultaneously, so VLAN groups can overlap or intersect. Edit/Delete a VLAN Group You can modify or delete the settings for an existing VLAN. 67

73 Group Sorted Mode User can select VLAN groups sorted mode: (1) sorted by name (2) sorted by VID. In the Edit/Delete a VLAN group page will display the result. 68

This page allows you to enable or disable the GVRP Configuration function. 95

101 IGMP The Internet Group Management Protocol (IGMP) is an internal protocol of the Internet Protocol (IP) suite. IP manages multicast traffic by using switches, routers, and hosts that support IGMP. Enabling IGMP allows the ports to detect IGMP queries and report packets and manage IP multicast traffic through the switch. IGMP have three fundamental types of message as follows: Message Description Query A message sent from the querier (IGMP router or switch) asking for a response from each host belonging to the multicast group. Report A message sent by a host to the querier to indicate that the host wants to be or is a member of a given group indicated in the report message. Leave Group A message sent by a host to the querier to indicate that the host has quit to be a member of a specific multicast group. 96

102 LACP The Link Aggregation Control Protocol (LACP) provides a standardized means for exchanging information between Partner Systems on a link to allow their Link Aggregation Control instances to reach agreement on the identity of the Link Aggregation Group to which the link belongs, move the link to that Link Aggregation Group, and enable its transmission and reception functions in an orderly manner. In conclusion, Link aggregation lets you group up to eight consecutive ports into a single dedicated connection. This feature can expand bandwidth to a device on the network. LACP operation requires full-duplex mode, more detail information refers to IEEE 802.3ad. The LACP Configuration allows you to configure the Working Port Setting, State Activity and view all LACP Status. 97
