WGSW-1602 16-Port Fast Ethernet Switch with 2 GbE slotsWeb-Based Management allows Switch configuration changes to be made using an Internet Web browser. This interface also allows for system monitoring of the Switch.
The management function of this interface runs as an unsigned Java applet. As a result, your browsers security setting should be set as following:
The arrangement of the Switch homepage consists of traditional web site hyperlinks for associated information and Java windows for system management.
Upon connecting to the switch via a web browser (i.e. Netscape Navigator 4.0), Key in the IP address of the switch or the alias name. The login screen will appear prompting for an administrator user name and password. Enter the password to access the switchs management mode. (or simply hit Enter if password protection is disabled). If a password box does not appear in the window, it means that the web browsers security setting is not correct for the JAVA applet. Section 3.1 outlines the correct browser settings.
Figure 3-1 : Password Screen
The default user name and password is root and switch, After the password is entered you will see the main menu screen.
Note: If password protection is enabled (using the console) without setting your own password, the default password is switch.

3.6 Address Manager
3.6.1 Static Addressing
Any system, whose MAC address and the port number are listed in this screen, will not be purged from the systems forwarding table by the ageing process.
Add a new entry
- Enter the MAC address and port in the appropriate boxes
- Click Add
Remove an exist entry
- Highlight that entry in the table, by clicking on the MAC address
- Choose Remove
Figure 3-10: Address Manager: Static Address
Ageing Time is a variable that must be configured. Its purpose is to determine the amount of time an entry is held in the forwarding tables.
The default value is set to 300 seconds, (or 5 minutes).
The administrator may change this value to any value between 10 and 824 seconds. After changing the value, click apply Figure 3-11: Address Manager: Address Ageing
3.7 Spanning Tree

3.8 VLAN Setup
3.8.1 Membership
The VLAN option allows users to define VLAN groups. The Add a new VLAN option will create a new VLAN. The VLAN tagging option is a standard set by the IEEE to facilitate the spanning of VLANs across multiple switches (Reference: Appendix A and IEEE Std 802.1Q-1998 Virtual Bridged Local Area Networks).
Add VLAN Group
- Enter the VLAN Id and name under the Add a new VLAN option.
- Click Apply
Remove VLAN Group
- Check the Remove VLAN box for the VLAN you want to remove
- Click Apply
Add VLAN Membership
- Click the box below the port number on the line of the VLAN so that a T (tagged) or U (untagged) appears.
Remove VLAN Membership
- Click the box again until a blank box appears. This will remove VLAN membership from the port.
Figure 3-14: VLAN Setup: Membership
3.8.2 PVID Settings
All untagged packets entering the switch will by default be tagged with the ID specified by the ports PVID. This screen allows you to specify the PVID for each port.
Figure 3-15: VLAN Setup: PVID Settings
3.9 Port Trunking
Port Trunking is a feature that allows multiple links between switches to work as one virtual link or aggregate link. Trunks can be defined for similar port types only. For example, a 10/100 port cannot form a Port Trunk with a gigabit port. For 10/100 ports, trunks can only be formed within the same cluster. A cluster is a set of eight ports (maximum) for WGSW-1602.
Figure 3-17: Port Trunking
Please be noted, the trunked switch should also support Port Trunking as well, for example another WGSW-1602 or WGSW-800 with trunking support turned on.
3.10 Port Mirroring
Port mirroring is a feature to help in the debugging of a network. This web interface page allows enabling or disabling of port mirroring and the setting of source and monitor ports. The Monitor port will show a copy of every packet that arrives or leaves the source port.
Figure 3-17: Port Mirroring
3.11 SNMP Management
The SNMP menu contains the following sub-menus:
Community Table Host Table Trap Settings 3.11.1 Community Table
In the Community Table the administrator can create different community strings with customized access by choosing combinations of GET, SET and TRAP rights.
Figure 3-18: SNMP Management: Community Table
3.11.2 Host Table
The SNMP Host Table screen allows you to add and remove hosts from access rights that have been granted to community groups. The permissions GET, SET and TRAP are assigned to a community name and then these permissions are assigned to individual machines by adding those machines and their IP address to the appropriate community string. Host Authorization can be Enabled or Disabled.
Figure 3-19: SNMP Management: Host Table
3.11.3 Trap Setting
The SNMP Trap Setting allows for the setup of authentication traps.
Authentication traps
- Enable: The system will generate a SNMP trap upon a host authorization failure
- Disable: The authentication traps will not be generated
All hosts in community strings with TRAP privileges will be notified when a trap condition occurs.
Figure 3-20: SNMP Management: Trap Settings
The statistics page allows the administrator to chart different system data. There are three parameters to set: Statistic, Refresh Rate, and Color. All charts have a maximum ceiling of 231-1. You can see the value of each bar or line in the chart by clicking on the bar.
Statistics: The type of system data to be monitored Refresh Rate: The time interval between automatic refreshes Color: The color setting for the chart When all of the variables are set, click Draw.
