1 Introduction

The 24/2Giga web smart switch is a high performance web-smart layer 2 switch that provides users with 24 switched 10/100/1000Mbps Ethernet ports and 2 shared mini-GBIC ports with auto-detection function. The management function can be accessed via out of band RS-232 terminal port connection and also via in-band IP access from any port and local or remote location. This switch is suitable for enterprise companies or SOHO users who want to build up a high speed network or backbone. With single-mode or multi-mode fibre transceivers you can link remote users or share remote resources. A web interface management facility provides control capability over

TCP/IP. This makes operation easy to manage with a browser at the local or remote side.

Non-blocking and maximum wire speed performance is supported on all switched ports. It also supports an auto-negotiation and MDI/-MDIX function on all switched 24 10/100/1000M RJ-45

Gigabit ports.

This switch supports both port-based VLAN and 802.1q (tag-based) VLAN. To increase bandwidth application, it supports 4 trunk groups with up to 8 ports. Moreover, these trunk ports provide redundant back-up should one or more ports malfunction in that trunking group.

1.1 Start to Manage This Switch

Plug-in the power source to power-up the switch. After the switch is powered-on and in a ready state

(both the LED indicators POWER and DIAG are lit), you can use any in-band Ethernet port to remotely manage it through a web browser. Alternatively use an RS-232 cable to plug-in the console port (on the rear panel) to locally do the simple system configurations by using the command line interface (CLI). The default IP and related settings for this interface are shown as follows:

„ IP address: 192.168.223.100

„ Network mask: 255.255.248.0

„ Default gateway:192.168.223.254

Try to use the default IP shown above to PING the switch from your PC to make sure the network connection is successful. The default IP address on this switch can be modified later for your needs.

If you encounter access problems you can just locally connect to the console port to get the correct

IP address for this system.

Now you can use the browser to launch the web-managed interface for this switch. This system only supports Microsoft Internet Explorer for web interface configuration.

The login dialog box (shown as below) will show up first when the switch’s IP address is entered in your browser.

Use the default username and password shown as below to complete the login procedure:

„ Username: admin

„ Password: 123

This username/password can be modified later for your needs.

6

1.2 Configuration Functions for the Switch

After the login is successfully validated, the switch’s home page – System page will show up. The left part on the page provides the function menus (shown as below) to activate to the individual configuration page.

The function menus contain two parts: Switch for setting up the switch functions and System for maintaining the system parameters.

Switch functions contain:

„ Port Status – to show port link status and configure port parameters

„ Port Statistics – to show packet statistic results passed through each port

„ Port-based VLAN – to setup the port-based VLAN

„ 802.1Q VLAN – to configure the tag-based VLAN

„ Trunk – to build up the trunk function

„ Mirror – to setup the port mirroring function

„ QOS – to configure the Quality of Service function

„ Rate & Storm Control – to limit the traffic rate and suppress the broadcast storm

System functions contain:

„ System Setup – to configure the required system information (such as IP address, etc.)

„ User Management – to maintain the login information to access the switch

„ Reboot System – to reboot the switch without writing default configurations

„ Reset System – to reboot the switch after writing default configurations

„ Logout – to log off the system

2 Configurations

2.1 Port Status

This page provides the current link status for all ports. You can select the Port Status menu to activate this page and to refresh the current port status.

This page provides the following information:

„ Port – to specify a port on the switch

„ Link Status – to show the port link status: Up / Down

„ Speed / Duplex – to show the current link speed (1G / 100M / 10M bps) and duplex mode

(Full / Half) while the port is linkup.

NOTE: Only the full duplex mode is supported while the link speed is 1Gbps.

„ Flow Control – to show the flow control capability is Enable / Disable for this port.

The status for the two columns: Speed/Duplex and Flow Control won’t show up while the port link is down. (The sign ‘-‘ represents the status is unavailable to display.)

If any trunk group is setup, a trunk group can be regarded as one logical port (e.g. Trk1 in the above figure is grouped by Port9 & Port10) which will show up just like the others. All the trunk member ports won’t be displayed. Section 2.7 (Trunk) describes port trunking in detail.

Click the Refresh button to manually get the most current link status for all ports.

2.2 Port Configuration

If you need to do the port configuration, just select the desired port by clicking the Port number in the Port Status page. Then the Port Configuration page (shown as below) for the selected port will be opened:

The following parameters will be provided and configured in the Port Configuration page:

„ Port – the selected port number to be configured (read only)

„ Admin – to unblock/block the traffic for the port

¾ Disable – to block all traffic for the port

¾ Enable – to enable the bi-directional traffic for the port

„ (Media --) Auto Negotiation – to enable/disable the capability of auto negotiation for setting up the link. The options provided for this function depend on the port type – combo ports (Port1

& Port2) shared with fibre media using mini-GBIC interface, or ordinary ports (from Port3 to

Port24) for copper media only. z 2 Options for combo ports (Port1 and Port2)

9 Fibre – Disable , Copper – Enable – to enable the copper but disable the fibre media

9 Fibre –Enable, Copper –Enable – to enable both media

NOTE: Only the Enable option is provided for copper media in combo ports. Force mode

(i.e. auto negotiation is disabled) is not supported for copper media in combo ports. z 2 Options for ordinary ports (Port3 to Port24, copper media only)

9 Disable – to disable for this port (force mode)

9 Enable – to enable for this port (auto mode)

The following figure shows the port configuration page for a combo port. (e.g. Port1)

9

„ Speed / Duplex – to setup the link speed and duplex mode in force mode

The options for this function can be selected only when the Auto Negotiation is Disabled (in

force mode) for copper media. There are 4 options for this parameter:

¾ 100Mbps Full – to set the speed 100Mbps in full duplex mode

¾ 100Mbps Half – to set the speed 100Mbps in half duplex mode

¾ 10Mbps Full – to set the speed 10Mbps in full duplex mode

¾ 10Mbps Half – to set the speed 10Mbps in half duplex mode

NOTE: Only full duplex mode is supported for 1Gbps link speed. For copper media, this system supports the link speed from 10Mbps to 1Gbps for auto mode, and from 10Mbps to 100Mbps for force mode. For fibre media, only the 1Gbps link speed is supported for

both auto and force mode.

„ Flow Control – to enable/disable flow control function

¾ Disable -- to disable for the port

¾ Enable – to enable for the port

„ Default Priority – to setup the priority of frames which will be referenced in QOS function

¾ 0 – 7 – to set the priority level (range = 0 ~ 7)

„ Security – to enable/disable port security function

If the per-port security is enabled and if a received frame contains a source MAC address that has already been learned in another port’s address table but not aged out, then the frame is dropped. Otherwise, the address table entry is updated with the new port’s information and the entry is updated.

¾ Disable -- to disable port security

¾ Enable – to enable port security

„ Jumbo Frame – to enable/disable jumbo frame function

If the per-port jumbo frame feature is enabled, the maximum frame size is 9216 bytes. In 100

Mbps mode, the maximum jumbo frame size supported is 9000 bytes

¾ Disable -- to disable jumbo frame support

¾ Enable – to enable jumbo frame support

After the desired options are selected for the above functions, click the Apply button to save the current settings to the switch and go back to the Port Status Page. Click the Cancel button to go back to Port Status page.

2.3 About the Copper/Fibre Media Auto-Detection

This switch provides an option to use either copper or fibre media for the first two combo ports -

Port1 and Port2. This means that you can setup the link by using either copper media to plug-in to the copper port or use fibre media to plug-in the mini-GBIC port. This switch will automatically detect which media is plugged into the port. If both copper and fibre media are plugged in the fibre media has higher priority than the copper to setup the link; the link on the copper media will

be down. The link for the copper media will be re-setup after the fibre media is un-plugged. The

Port Status page will show the current link status according to the active media linking.

NOTE: The link status will take 10 seconds to be stable after any port mode changing (copper /

fibre media switching or auto / force mode changing for fibre media.) for combo ports.

11

2.4 Port Statistics

The Port Statistics function lets you see the TX/RX packets through each port.

The Clear Counters button will clear all packet counters to 0. The Refresh button will get port statistics again.

You can check each ports statistics more precisely. Just click the Port number to see the detailed information.

2.5 Port-Based VLAN

The port-based VLAN divides the ports into different Virtual LAN domain groups. After setting the port-based VLAN, the different VLAN groups can’t access each other. The VLAN initial setting page is shown as below:

You need to click the Enable/Disable link text to enable/disable the port-based VLAN. When port-based VLAN is enabled, the 802.1Q VLAN will be disabled automatically. The port-based

VLAN and 802.1Q VLAN cannot co-exist at the same time.

You can add, delete, and modify the port-based VLAN for your needs. This system supports up to

32 port-based VLAN groups for manual entry. The following pages will describe in detail how to configure the port-based VLAN.

NOTE: A default port-based VLAN entry (No=1) is initially created by the system. This VLAN entry contains members for all ports. It can be regarded as no VLAN function because all ports are in the same group and no traffic isolation between any two ports. If there are new port-based VLAN groups created, the VLAN No. 1 will contain no members. The group No. 1 is a read-only VLAN group. And there are only 2 situations for this VLAN – all ports are

member ports, and all ports are not member ports.

14

2.5.1 Add Port-Based VLAN Groups

To add a port-based VLAN group, select the Create New VLAN in the VLAN NO dropdown of the

Port-Based VLAN page shown as below:

After selecting the Create New VLAN, the page will be changed like this:

In the above page, VLAN NO will auto setup. Users just need to set VLAN Port Members. After the settings are complete, press the Create button to go back to the VLAN initial setting page. The

Cancel button lets the user give up the settings and go back to the VLAN initial setting page.

15

Below is the example page when the user sets Port1-12 to the VLAN Group2 after clicking the

Create button. Now there is a VLAN group No.2 created with the member Port1-12.

While the group No.2 is created, all the members in group No.1 are removed to operate the VLAN function.

16

2.5.2 Delete Port-Based VLAN Groups

To delete a port-based VLAN group, just select a desired group (e.g. No.2) to be removed and click the Remove This VLAN button.

Pressing the Remove This VLAN button results in the following:

Now all ports are set to the members in VLAN group No.1.

17

2.5.3 Edit Port-Based VLAN Groups

To edit the current port-based VLAN group, first select the group (e.g. group No. 3) you want to edit

(to add Port7 & Port8 as members) and click the Apply button to activate the setting.

The following figure shows the configuration for the selected group (e.g. No.3).

18

2.6 802.1Q VLAN

IEEE 802.1q (tag-based) VLAN can add or strip the 802.1q tag depending on the requirements of the individual transmitting port. Click the 802.1Q VLAN menu to activate the following pages to do the configurations.

VLAN ID 1 is the default 802.1Q VLAN. VLAN ID 1 cannot be deleted. However, the VLAN ID 1 group member can be changed.

Incorrect 802.1Q VLAN settings will cause the web access to fail to connect. You can use the CLI

(Command Line Interface) to recover. The detailed CLI operating guide will be discussed in section

2.14.

Here is a simple way to recover the web access to the switch.

1. In CLI, type VE to disable 802.1Q VLAN

2. Go to 802.1Q VLAN web interface. Set the default VLAN ID 1 group member(01-24) to U

3. Go back to CLI mode, type VV to set Admin PVID (port no.=25) to 1.

4. In CLI mode, type VE to enable 802.1Q VLAN. You can access the web in the 802.1Q VLAN enable environment now.

Currently this system supports up to 32 tag-based VLAN groups for manual entry. The following pages will describe in detail how to do these configurations.

19

2.6.1 Enable/Disable VLAN

In the 802.1Q VLAN page you can enable/disable the tag-based VLAN function by clicking

(Enable) or (Disable) besides the page header:

¾ Enable – to activate the tag-based VLAN function (port-based VLAN function will automatically be disabled).

¾ Disable – to de-activate the tag-based VLAN function, even though there are some VLAN entries created. (i.e. any tag-based VLAN entry is still retained although tag-based VLAN function is disabled. Port-based VLAN function will be auto enabled.)

20

2.6.2 802.1Q VLAN Port Configuration

Click the Port number to enter the port configuration page for 802.1q VLAN.

The following figure shows the 802.1Q VLAN Port Configuration page by port. (e.g. Port10)

You can set the individual port for configuring the 802.1q settings in the following fields:

¾ PVID – enter a valid VLAN ID(1-4094), and PVID must be one of the existing VLAN group

ID.

¾ UnTag Frame – Accept or drop incoming untag frames.

¾ Tag Frame – Accept or drop incoming tag frames.

Finally, there are 2 buttons to select:

Apply: To submit the port configuration settings to the switch.

Back: To go back to the 802.1q main setting page.

21

2.6.3 802.1Q VLAN Config

The following figure is the page to add/delete/edit the 802.1q VLAN entry. Each VLAN entry has 3 parameters, VID, Tag Members and UnTag Members to be assigned.

After selecting Create New VLAN the figure shown as below will be displayed:

¾ VID – a unique VLAN ID. The range is from 1 to 4094

¾ Tag Members & UnTag Members – Click the image directly, it will switch to Not Member,

Tag Member or Untag Member.

Input the VID (1-4094) and check the member row to select the ports which belong to this VLAN group. After these settings are complete click the Create button to submit the data to the switch.

Click the Cancel button to abort the actions and go back to the VLAN Config page.

22

Here is an example of how to configure the 802.1q VLAN. There are four existing 802.1q VLAN entries as shown below.

You can delete the 802.1q VLAN entry. Click a radio button on the Select column to select the entry to be deleted (e.g. VID = 200), then click the Remove This VLAN button to do the deletion.

After the action mentioned above, the 802.1q VLAN table will be changed like this:

The VID entry (VID=200) is successfully deleted.

23

If you would like to edit the parameters of an 802.1q VLAN, just select a VID to be changed (e.g.

VID =300) then click the Apply button to do the modifications: Port 17 and Port18 are selected to be the tag members of this group.

Finally, click the Apply button to do the changes.

24

2.7 Trunk

This 24G web smart switch supports MAC-based trunking, which allows more than one port to be grouped together as a single link connection between two switch devices. This is also useful for switch-to-server and switch-to-router applications. The 24G web smart switch allows four trunk groups that can accommodate up to eight trunk members. A port in one trunk group cannot be a member of another trunk simultaneously. This feature provides redundancy and increases the effective bandwidth through a link. The traffic patterns can be more balanced between the ports within a trunk group by dynamically performing the MAC-based algorithm. It is supported only on point-to-point links with MACs operating in full duplex mode. All links in the same trunk group must operate at the same rate.

The 24G web smart switch provides dynamic failover when trunking is enabled. If a port in the trunk group fails, the other ports of the trunk group assume traffic designated automatically for the trunk.

The links within the trunk group should have an equal amount of traffic. To achieve this, the switch performs load balancing based on a distribution algorithm.

The following parameters are required to be set:

„ Distribution Criterion – chooses the distribution algorithm with which the switch performs load balancing based on:

¾ SA (Source MAC Address)

¾ DA (Destination MAC Address)

¾ SA + DA (both SA and DA)

„ Member – the member port(s) of trunk group(s)

Select the Trunk menu on the web page to activate the page shown as below.

25

Because a trunk port can be aggregated by the member ports with the same configurations in most functions for each other, there are some rules to limit the configurations of the trunking. The following section will list the related rules for this function.

26

2.7.1 Trunking Rules

The following rules will limit the configurations for port trunking:

„ The attributes of all trunk member ports in Port Configuration, Mirror, Rate Control, 802.1Q

VLAN and Port-Based VLAN functions must be the same.

„ All trunk member ports can not be a capture port or monitored port in Mirror function.

„ If Port1/Port2 using the fibre media wants to be grouped with the ports using pure copper

(Port3 – Port24) as a trunk port, the auto negotiation option must be set to Enable for all member ports. If both Port1 & Port2 are the only trunk member ports and they are using fibre media, the auto negotiation option can be Enable or Disable.

„ After enabling a trunk group, a new trunk port will be created in the port list. For example,

Port2, Port4, and Port6 belong to Trunk 1. Check the other page (Port Status) with port list,

Trk1 port will be added after all normal ports. The member ports of this trunk group will disappear.

27

„ When the enabled trunk group is set to disabled, all trunk member ports will be released to ordinary ports and their functions can be configured individually. At that moment, their configuration attributes will be retained to the last settings while they were member ports of the trunk group. The following 3 figures show how the port configurations (e.g. Port6) will be retained before and after the trunk (e.g. Trk1) is disabled.

28

2.7.2 Get/Refresh the Latest Trunk Settings

Click the Trunk menu on the web page, the latest trunk settings on the switch will be displayed.

This is also the page to configure the trunk function.

31

2.7.5 Disable Trunk

¾ Step 1: Click the Not Trunking.

¾ Step 2: Click the Apply button to disable trunk.

32

2.8 Port Mirroring

Port mirroring allows ingress and/or egress traffic to be monitored by a single port. The single port is mirror capture port. The 24G web smart switch can be configured to mirror the ingress and/or egress traffic of another port. Port monitoring is independent of L2 switching. The networking manager can monitor all traffic sent/received through the 24G web smart switch.

Select the Mirror menu on the web page to activate the configuration page.

33

2.8.1 Get/Refresh the Latest Mirror Settings

Click the Mirror menu on the web page. The mirror settings on the switch will be displayed. This is also the page to configure the port mirroring function.

The following parameters are required to be set:

„ Mirroring Options – There are four options for each port:

¾ Disable Mirror – to disable mirror function.

¾ Mirror All Frames – to set the corresponsive port to be a monitored port to investigate bi-directional traffic.

¾ Mirror Incoming Frames – to set the corresponsive port to be a monitored port to investigate only ingress (receiving, Rx) traffic.

¾ Mirror Outgoing Frames – to set the corresponsive port to be a monitored port to investigate only egress (forwarding, Tx) traffic.

„ Monitored Port – The port which is monitored.

„ Capture Port – All traffic mirrored from the monitored port are received on the capture port.

34

2.8.2 Enable Mirror

36

2.8.4 Disable Mirror

¾ Step 1: Choose Mirror option to be Disable Mirror.

¾ Step 2: Click the Apply button to disable mirroring.

37

2.9 QOS (Quality of Service)

The 24G web smart switch provides up to four internal transmit queues per port to support four different traffic priorities. The high-priority traffic experiences less delay in the switch than that of lower priority traffic under congested conditions. The 24G web smart switch provides three types of

QOS. It can assign the packet to one of four transmit queues according to 802.1P QOS. If the incoming packet is untagged, the 24G web smart switch uses the priority field in the per-port

Default Priority in the Port Config page to assign the packet to one of four transmit queues. If the incoming packet is tagged or priority tagged, the 24G web smart switch uses the priority field in the incoming packet tag to assign the packet to one of four transmit queues.

The 24G web smart switch also provides a remap function. This switch always inserts the packet into the Tx Queue by priority ID. Users can assign the map between priority and queues. This switch handles the packets transmit by the Tx Queue Weight Setting when the Weighted Round-Robin algorithm is selected.

Select the QOS menu on the web page to activate the page shown as below.

38

2.9.1 Get/Refresh the Latest QOS Settings

Click the QOS menu on the web page. The QOS settings on the switch will be displayed. This is also the page to configure QOS.

The following parameters are provided to be set:

„ Scheduling Method

¾ Strict Priority – to set this switch to transmit packets with Strict Priority algorithm

¾ Weighted Round Robin – to set this switch to transmit packets with Weighted Round

Robin algorithm

„ Priority/Queue Map

¾ To set the Priority and Queue map.

„ Weight

¾ To set the weight for every transmit queue. (Weight range: 1 ~ 15)

¾ The weight of higher queue should not be less than the lower queue.
