Working with Web-based Interface
Users can use any Java-enable (support Java 1.1.x) browsers, such as Netscape Communicator 4.05 (or later) or Microsoft Internet Explorer 4.0 (or later), to manage the FS3-1600 switch via the Web-based Interface. User just input the IP address of the FS3-1600 switch, then browser will connect to FS3-1600 and show the FS3-1600s Login screen (the Login screen is the home page of the FS3-1600 switch). The more detail about setting Java Security for getting advance network management functions, please see Appendix D. The GUI (Graphic User Interface) of Login screen is shown in Figure 6 - 1
Figure 6-1: The Login Screen GUI
The Login Screen need an user to input the community name information:
Community Name : Enter an authorized Community name to read or write any MIB objects via SNMP protocol. The factory default Read Community is public.
The Figure

Click the Exit button (see the right-side button) will close Device Manager screen and Device Detail screen (if Device Manager screen is opened).
Line Speed
The LAN Port screen is the same with Figure 6-4. From port 1 to port 8 are described in Figure 6-4, if you want to configure a port that is located at the range of port 9 and port 16.
The LAN Port function group is built-in four parts configuration modes for each port. They are:
There are five Line Speed modes described in Table 6-1, the default mode is Auto Negotiate mode.
Table 6-1 : Line Speed ModesLine Speed |
Description |
Auto Negotiate | In auto-negotiation or auto-sense mode. |
10Mbps Half Duplex | Force in 10Mbps half-duplex mode without auto-negotiation capability. |
10Mbps Full Duplex | Force in 10Mbps full-duplex mode without auto-negotiation capability. |
100Mbps Half Duplex | Force in 100Mbps half-duplex mode without auto-negotiation capability. |
100Mbps Full Duplex | Force in 100Mbps full-duplex mode without auto-negotiation capability. |
There are two Congestion Control modes described in Table 6-2, the default mode is Disable mode. FS3-1600s Congestion Control can support both full-duplex and half-duplex modes. In full-duplex mode, FS3-1600 implements IEEE 802.3x as the congestion control method. In half-duplex mode, FS3-1600 implements back-pressure as the congestion control method.

There are many existing Ethernet switches, they are not implemented the IEEE 802.3x full-duplex flow control method. Dont enable the congestion control function while connecting these Ethernet switches that are not implemented the IEEE 802.3x method. |
Switching Modes |
Description |
Store-and-Forward | Eliminates runt packets, but imposes longer forwarding latency. |
Cut-through | Provides minimized runt packets with limited forwarding latency. |
There are two modes of Link Type described in Table 6-4, the default mode is Access Port mode.
Table 6-4 : Link Type ModesLink Type Modes |
Description |
Access Port |
Access ports typically connect the FS3-1600 switch to network nodes other than switches. Access ports can also connect the FS3-1600 switch to other switches that do not support 802.1Q tagging. Packets sent from an access port are always VLAN untagged, unless overridden by the specific setting for a specific VLAN. |
Trunk Port |
Trunk ports typically interconnect two switches. Packets sent from a trunk port are always VLAN tagged, unless overridden by a setting for a specific VLAN. A trunk port cannot be used to connect the FS3-1600 switch to another switch that does not support 802.1Q tagging. |
Click the VLAN function group in the Device Detail screen, then you can see the VLAN screen (Figure 6 5). The VLAN function group provides VLAN management functions as follows:
Figure 6-5 : The VLAN Screen
The are two major areas in Figure 6-5. They are
If you want to change the properties of the created VLAN group, please select the new created VLAN with mouse in the Created VLAN area of Figure 6-6 in advance. Then click Property button in Figure 6-6, after that you can see the dialogue in next page (Figure 6-7).
Figure 6-7: VLAN Property Dialogue
In Figure 6-7, you can edit your desired VLAN name in VLAN Name field. It is optional that inputs a set of IP network information for this new created VLAN, the set of IP network information contains the following fields:
To select VLAN members is an important thing after creating a VLAN. The selection procedure is described as follows:
If you want to get the properties of any VLAN member, please select the VLAN member with mouse in the Created VLAN area of Figure 6 5 in advance. Then click Property button in Figure 6-5, after that you can see the dialogue to show member properties. (Figure 6-8).
The Member property dialogue only shows the properties information of selected VLAN member, each property in this dialogue cannot be changed.
If you want to remove the VLAN or VLAN member in the Created VLAN area in Figure 6-5, firstly select the VLAN or VLAN member which you want to remove. Then click the remove button
Update VLAN Information
If you want to update all of the VLAN
information immediately, please press

Click the Spanning Tree function group in the Device Detail screen, then you can see the Spanning Tree screen (Figure 6-9). The Spanning function group provides Spanning Tree management functions.
Bridge Properties Configuration
All bridge properties one can change in console can be changed in the right part of the Spanning Tree screen (see Figure 6-9). The dark part shows bridge properties that cant be changed by administrators. All settings will be set to switch after the right-bottom Apply button being pressed.
There are four function groups in RMON screen :
Click the Event button (see the right-side button), then the Web browser will show the RMON Event
screen, see Figure 6-11, Figure 6-12
Figure 6-11: The Event and Log screen
Figure 6-12: The Trap screen
Figure 6-12 shows the trap table. The trap table displays the traps delivered from the switch and users can also print out traps or save to files (please use A4 landscape printing format). The trap function wont be available on every platform due to the security restrictions of the browsers. It is available now only on IE4.0 and turn on the unsigned applet to full permissions.
Once you click the Statistic button, the Interface Dialog will show up, see Figure 6-14
You may choose an interface(port) you want to see the statistics datas in the Interface field. The Polling Rate field tells system the delay time (in seconds) to get next datas and refreshes the screen. And the in the Background field one can decide whether the statistic screen will be execute when goes to background or suspended itself. Choose suspended will save more system resources when system is overloaded.
In the left-top is the Packet Type Distribution window. It shows the amount of different types of packets pass through the switch.
In the right-top is the Packet Size Distribution window. It shows the amount of different sizes of packets pass through the switch.
In the left-bottom is the Switch Utilization window. It shows the utilization of this switch. And the utilization is obtain from the formula below (see RFC1757).
Utilization = | Pkts * (9.6 + 6.4) + (Octets * 0.8) |
Interval * 10,000 |
where Interval = number of seconds, and the value is ranged from 0 to 100 percent.
In the right-bottom is the Packet Flow Trend window. It shows both the number of packets passed through the switch (Red line, scale on the left) and the number of collisions (Gray line, scale on the right)
Click the Alarm button (see the right-side button), then the Web browser will show the RMON Alarm
screen, see Figure 6-15.
First the alarm table will show up. The table will display the existed alarms set before. You can add, modify, and delete alarms on it. When you press the Add or Modify button, the Alarm screen will extend to Figure 6-16.
One can now set the values on the extended Alarm screen. The detail fields will be described below:
The interval in seconds over which the data is sampled and compared with the rising and falling thresholds. When setting this variable, care should be taken in the case of deltaValue sampling-the interval should be set short enough that the sampled variable is very unlikely to increase or decrease by more than 2^31-1 during a single sampling interval.
One may press the Show MIB Tree button in the right-bottom corner to manage all MIB objects in the MIB tree. See Figure 6-17
In the left of the MIB Tree panel shows the entire MIB Tree. One can double click on a node of the MIB Tree and all instances of this node and nodes on its sub-tree will be displayed on the right instance table (double click again will stop). Then one can simply double click on the instance he wants to manage and this instance will be added to the Managed OID.
Click the History button (see the right-side button), then the Web browser will
show the RMON History screen, see Figure 6-18.
RMON history group enables a network engineer to take periodic statistical samples from a segment and store them within the probe for later retrieval and analysis. There are three function pages in History screen:
Figure 6 - 18: History Configure Page
This page is the default page of History screen (see Figure 6-18), this page shows the history control table and provide GUI to help user to create history control entry. (each row in history control table is called a history control entry) Each history control entry determine a ether history table that are shown in the History View page. There are seven fields in each history control entry, the meaning of each field is described as follows.
The history control entry cannot be modified directly, if you want to modify one history control entry, please delete the row you want to modify, then add a new one. The procedure to add and delete a history control entry is described in the next page.
To add a history control entry just click the add button
Figure 6-19: History Control Dialogue
You can choose an interface from the Interface drop-list, to fill the Data Source field of history control entry. Sample interval is the time between each sampling. The sample interval value can be used as the value of Interval field of history control entry. Sample length is the total time length the history control entry to get statistic sample. The relationship of requested value, sample interval, and sample length is as follows:
requested value = (sample length) / (sample interval)
After input each value in History Control Dialogue and press OK button, then a new history control entry is created.
To remove a history control entry, you would select a row in history
control table by mouse, then click the delete button in Figure 6-18 to delete the
history control entry.
History View page shows the ether history table which is corresponding to the history control entry selected in the History Configure page. Before select this page, make sure any row in history control table is selected. The outlook of History View page is shown in Figure 6-20.

MIB browser contains three display components:
Tree View Area: Tree View area (the green area) shows the current MIB module in tree structure. List View Area: List View area (the yellow area) lists the child nodes of the selected node, which is selected in tree view area. In addition, if the selected node is a leaf node, then list view will show the associated information in detail.Output Area : Output area (the red area) shows the result of get MIB function.
Change MIB Module
With MIB browser, you can change MIB module by selecting the MIB module drop list (see left-side drop list) in the toolbar. FS3-1600 currently provide RFC 1213-MIB, RMON-MIB, BRIDGE-MIB tree MIB modules.
get MIB actionTo perform get MIB action, you should select a node in tree view area in advance, then you can click the get MIB button
to perform the get MIB action. The result of get MIB action would be displayed in the output area. If you select a leaf node in tree view area, the output area only shows the value of object instance of selected node. If you select a node with child, the output area shows all the values of child nodes of selected node.
You can click the stop button
