2-2. Module Type Configuration

The switch is modularized. In addition to two GBIC ports, there are three modules selectable for your needs. For the different type modules, some module/port settings maybe need to be reconfigured. You can configure the module type by this function. The system can also configure all the port settings of the module to the pre-defined values for you. If some of the detail settings of each port do not meet your needs, you can change them on a port-by-port basis from the Port Controls Page. The default module type is 8-port 10/100 Base-TX RJ-45.

Available module types:

1. No Module

2. 8-Port 10/100 Base-TX RJ-45

2-5-2. 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. The default is 300 seconds.

Max bridge transmit delay bound control: Limit the packets queuing time in the Switch. If enable, the packets queued exceed this time will be dropped. This valid value are 1 sec, 2 sec, 4 sec and off.

Enable Low Queue Delay Bound: Limit the low priority packets queuing time in Switch. If the low priority packets stay in Switch exceed the Max Delay Time, it will be sent. The valid range is 1~255 ms.

NOTE: Make sure that “Max bridge transit delay bound control” is

enabled before activating the Delay Bound.

Modularized 24+2G Switch

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 port's total bandwidth used by broadcast traffic. When broadcast traffic for a port rises above this threshold, broadcast storm control will activate. The valid threshold values are 5%, 10%, 15%, 20%, 25% and OFF.

Priority Queue Service settings:

First Come First Service (FCFS): The sequence of packets sent

depends on the order they arrive.

All High before Low (AHBL): The high priority packets are sent before low priority packets.

Weighted Round Robin (WRR): Select the preferred ratio of high and low priority packets sent by the switch in its 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 - Priority Levels:

designated high or low priority.

Collisions Retry Forever: Disable – In half-duplex, if collision occurs,

0~7 QoS levels can be assigned to

Modularized 24+2G Switch

the Switch will retry send 48 times and before dropping the frame. Enable – In half-duplex, if collision occurs, the Switch will retry to send frames indefinitely.

2-5-3. Console Port Information

1. Console is a standard UART interface to communicate with the Serial Port. The user can launch windows HyperTerminal program to link with the switch. See section three for details

Bits per seconds: 38400 Data bits: 8 Parity: none Stop Bits: 1 Flow control: none

Modularized 24+2G Switch

2-5-4. Port Controls

Use this page to change the status of each port.

1. State: User can disable or enable this port control.

2. Auto-Negotiation: User can set auto-negotiation modes:

Force - specify the speed/duplex on this port with auto-negotiation

enable. Auto NWay – for the Switch to automatically determine the highest speed and duplex mode possible

3. Speed: User can set 100Mbps or 10Mbps speed on Port1~Port24. User can set 1000Mbps, 100Mbps or 10Mbps speed on Port25~Port26 (depending on module card specifications).

4. Duplex: User can set full duplex or half-duplex mode for each port.

5. Flows control: Full: User can set full - flow control function (pause). Half: User can set half – flow control (backpressure).

Modularized 24+2G Switch

6. Rate Control: port1 ~ port 24, supports by-port ingress and egress

rate control. For example, assume port 1 is 10Mbps, users can set its effective egress rate to 1Mbps, ingress rate is 500Kbps. The Switch will perform flow control or backpressure to confine the ingress rate to meet the specified rate. Ingress: Type the port effective ingress rate. The valid range is 0 ~

1000. 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.

7. Priority:

This static priority based on port, if you set the port to high

priority, the priority of incoming frames to this port will always be high

8. 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 . 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 settings, then click Apply to set the Switch with information provided on this page.

2-5-5. 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 Aggregation Group and enable its transmission and reception functions in an orderly manner.

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.

Modularized 24+2G Switch

2-5-5-1. 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.

1. Group ID: There are seven trunk groups to provide configures. Choose the "group id" and click "Get".

2. 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.

3. Work ports: Allow max. four ports can be aggregated at the same time. If LACP static trunking group, the exceed ports are standby and able to aggregate if work ports fail. If local static trunking group, the number must be the same as the group member ports.

4. Select the ports to join the trunking group. Allow max. four ports can be aggregated at the same time.

5. If LACP enable, you can configure LACP Active/Passive status in each port on State Activity page.

Click Apply.

Modularized 24+2G Switch

2-5-5-2. Aggregator Information

When setting LACP aggregator, you can view related information as follows.

1. This page provides LACP current status. In this case, NO GROUP ACTIVE, since LACP is not enabled.

2. This page displays Static Trunking groups.

Modularized 24+2G Switch

2-5-5-3. State Activity

Active (select): The port automatically sends LACP protocol packets. Passive (no select): The port does not automatically send LACP protocol

packets, and respond only if it receives LACP protocol packets from another networking 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 LACP protocol packet from another networking device.

2. If you are active LACP’s actor, when you select trunking port, the active status will be created automatically.

2-5-6. Filter Database

2-5-6-1. IGMP Snooping

Modularized 24+2G Switch

2-5-6-2. Static MAC Address

When you add a static MAC address, it is stored 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 device is disconnected or powered-off, and is then active on the network again.

The Switch supports 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 different multicast group, VID and member ports here. IP multicast addresses range from 224.0.0.0 to 239.255.255.255.

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 messages. See table below:

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.

1. From the main menu, click administrator Filter Database Static MAC

Address.

2. 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.

3. In the Port Number box, enter a port number.

4. 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) associated with the MAC address.

5. Click on the Add button.

Modularized 24+2G Switch

2-5-6-3. MAC Filtering

MAC address filtering allows the Switch to drop unwanted traffic. Traffic is filtered based on the destination addresses.

Modularized 24+2G Switch

2-5-7. 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 in 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 Switch supports port-based, 802.1Q (tagged-based) and protocol-based VLAN in web management page. In the default configuration, VLAN support is disabled. There are a few configuration examples in Appendix B for your reference.

1. In the MAC Address box, enter the MAC addresses that are to be filtered.

2. If tag-based (802.1Q) VLAN are set up on the Switch, in the VLAN ID box type the VID associated with the MAC address.

3. Click the on Add button.

4. Choose the MAC address that you want to delete and then click on

the Delete button

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 is enabled, the VLAN-tagging is ignored.

GROUP 1 SALES

GROUP 2 R&D

Modularized 24+2G Switch

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. Tags contain 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 has to either:

a. Be capable of tagging packets it sends with VLAN tags, OR b. Be 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.

The feature can be applied for accommodating devices that you want to participate in the VLAN, but don’t support tagging. Therefore, the system can add VAN tags to untagged frames which are based on PVID or on different protocols.

The Switch 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. A port can join more than one different protocol VLANs, but a port can’t apply a same protocol twice for the VLAN configuration purpose. Otherwise you will see the error message: “Save fail for ethertype conflict” when trying to configure VLANs.

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.

The above screen is the Main Tag-based VLAN page

1. From the main menu, click administrator VLAN configuration,

click Add then you will see the page as follow.

2. Type a name for the new VLAN.

3. Type a VID number (between 2-4094). The default is 1 (In total,

there are 255 VLANs that can be configured).

4. Choose the protocol type. If you are not applying protocol VLAN,

you must set the value to “NONE”. You can’t set a port to join more than one VLANs/VIDs with a same protocol.

5. From the Available ports box, select ports to add to the switch

and click “Add >>”. If the trunk groups exist, you can see displayed as: TRK1, TRK2, …, …, and you can configure it to bet a member of the VLAN or not.

6. Click Next. Then you can view the page as follow.

Modularized 24+2G Switch

7. After adding ports to the VLAN, you use the above page to set the outgoing frames as VLAN-tagged frames or not. The default is ‘Untag’. Using the dropdown box, select ‘Tag’ or ‘Untag’ and click Apply.

Note: Unless you are sure the network has no tag-unaware devices, you should leave the

default setting of the outgoing frames to “Untag”.

Tag: Outgoing frames with VLAN-tagging. Untag: Outgoing frames without VLAN-tagging.

Configure port VID settings

From the main tag-based (IEEE 802.1Q) VLAN page, click Port VID Settings. Configure port VID settings

From the Main Tag-based VLAN page, click

[Port VID] (shown on the insert to the right) to

enter the Port VID Settings menu.

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 1~4095, default PVID is 1.

Ports may share a same PVID, but all the PVIDs of the ports on the switch must belong to the same 256 number group segment. (For example: 1~255, 256~511,…3840~4095). This is in order to allow for faster Ingress processing of frames. The PVID will be used for VLAN ID tagging to untagged frames.

Note also that the PVID must be the same as the member VLAN group IDs that the port belongs to, else the untagged traffic will be dropped. This is because the port can’t transmit a frame with a VLAN Group ID it doesn’t belong to. If a port also joins a protocol VLAN, the switch will apply the protocol VLAN ID to untagged frames first. If the frame doesn’t meet one of the protocols the port has defined, then the PVID will be applied for this frame.

Ingress Filtering

Ingress filtering lets frames belonging to a specific VLAN to be forwarded. The Switch has two ingress filtering rule as follows:

Modularized 24+2G Switch

Rule 1: Forward only packets with VID matching this port's configured

VID. The default is “Enable”. By default, only the packets with VID matching this port’s configured VID can pass the port.

Rule 2: Drop Untagged Frame. The default is “Disable”. By default,

untagged packets can pass the port.

2-5-8. Spanning Tree

The Spanning Tree Protocol (STP) is a standardized method (IEEE 802.1D) for avoiding loops in switched networks. When STP is enabled, it ensures 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 recommend that you enable STP on all switches to ensure that only a single active path on the network exists.

1. From the Spanning Tree Configuration Menu (shown below), you can create a new value for the STP parameter, then click the Apply button to set it. You can view spanning tree information the Root Bridge from the same screen.

Modularized 24+2G Switch

2. You can view spanning tree status about the Switch from the following screen.

Parameter Description

3. From the Spanning Tree Configuration Menu, click PerPort Configuration to configure STP parameters on each port, click on the Apply button to set it.

You can change forward delay time, The number of seconds a port waits before changing from its Spanning Tree Protocol learning and listening states to the forwarding status. Enter a time in seconds from 4 through to 30.

Path Cost Specifies the path cost of the port. The Switch uses this

to determine which port are the forwarding ports. The lowest numbers assigned are the forwarding ports. The range is between 1 and 65535 and the default value base on IEEE802.1D are: 10Mb/s = 50-600 100Mb/s = 10-60 1000Mb/s = 3-10

2-5-9. Port Mirroring

Port Mirroring is a method to monitor traffic in switched networks. Traffic through ports can be monitored by one specific port. That is, traffic going in or out monitored ports will be duplicated to a mirror port.

Parameter Description

Port Priority You can make the port more or less likely in becoming

the root port. The range is between 0-255. Its default setting is 128. The lowest number has the highest priority.

Roving Analysis State: Roving analysis is the mirroring of Fast Ethernet port traffic to another port of the same media type within a system that has an RMON probe or analyzer attached. This port allows external RMON probes (network analyzers) to monitor traffic on any switched segment.

You can monitor a designated roving analysis port to: Analyze traffic loads on each segment so that you can continually optimize your network loads by moving network segments, or troubleshoot switched network problems (for example, to find out why a particular segment has so much traffic)

Modularized 24+2G Switch

Analysis Port: You can have as many as 16 network analyzers

connected to a system. For more accurate analysis, attach the analyzer to a dedicated port instead of through a repeater. When the analyzer port is set, it cannot receive or transmit any other data. Instead, it receives only the data from the ports to be monitored.

Monitor Port: The ports you want to monitor. All monitor port traffic will be copied to mirror port. You can select max 25 monitor ports in the switch. User can choose which port that they want to monitor in only one mirror mode. For each port 1-24 you wish to monitor, click the check box next that port. When finished, click Apply

2-5-10. SNMP

802.1Q Tag-VLAN Application Example

An IEEE 802.1Q VLAN is a group of ports that can be located anywhere in the network, but communicate as though they belong to the same physical segment. VLANs help to simplify network management by allowing you to move devices to a new VLAN without having to change any physical connections. VLANs can be easily organized to reflect departmental groups (such as Marketing or R&D), usage groups (such as e-mail), or multicast groups (used for multimedia applications such as videoconferencing).

VLANs provide greater network efficiency by reducing broadcast traffic, and allow you to make network changes without having to update IP addresses or IP subnets. VLANs inherently provide a high level of network security since traffic must pass through a configured Layer 3 link to reach a different VLAN. Figure 1 demonstrate a VLAN example with 2 switches and 4 VLAN groups. Below are details and configuration steps .

In Fig 1, we will have a fibre (1000SX) carrying tagged VLANs with trivial VIDs (254,176,102,2) only. This will be connected to the uplink port (26) on a switch SW1. The internal management interface of this SW1 will have an IP address on VLAN VID 254 (e.g. 137.92.254.10). A 1000SX port (25) on this SW1 will then be connected to the uplink port (26) on SW2 and it will carry tagged packets VIDS (254.176.102.2). Again the management port of the SW2 will be on VLANs VID 254 (e.g. 137.92.254.11). We will have a few ports on the 550+ to egress untagged packets on VLANs 254.76.102.2. And we can telnet/SNMP the management interfaces of both the SW1 and the SW2. That a laptop on either VLANs 254.176.102.3 can see the rest of the network(s).

Connecting VLAN Groups

The switch supports communication within a common VLAN. However, if you have devices in separate VLANs that need to communicate, and it is not practical to include these devices in a common VLAN, then the VLANs can be connected via the Layer 3 routing provided by another Layer 3 switch. In Fig 3, we use the router with two network interfaces (192.168.0.1 /24, 192.168.1.1 /24) to provide the Layer 3 routing.

Protocol VLAN Application Example

In order for an end station to send packets to different VLANs, 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. The Protocol-based VLAN feature of the switch can be applied for accommodating devices that you want to participate in the VLAN by means of built-in knowledge of layer 2 packet formats used by selected popular protocols, such as IP and Novell IPX. The following example will demonstrate you how to configure the switch for protocol—based VLAN application. Figure 1 shows you two switches with workstations and servers which are going to work by using protocol VLAN.
