3.5.1  General Info

The following fields are accessible under the general info page:

The Media Access Control (MAC) address and the System Description are not configurable.

Notice that there are two buttons, Apply and Reload, in the lower part of the window. The Reload button is used for reloading values while the Apply button is for sending values to the Switch.

3.5.2 IP Settings

There are three tunable parameters to be set by the system administrator.

Figure 3-4: System Manager: IP Settings

      1. Password Admin

The password entered is encrypted on the screen and will display as a sequence of asterisks (*).

Note: Password protection is optional and can only be enabled through the console interface. If the password protection is enabled without setting your own password, the default password is ¡§switch¡¨.

      1. NVRAM Admin

After making any changes to the screens within the Web Interface, users must save the changed settings to NVRAM. This is done in the system administration screen in order for the new settings to remain after a system reboot.

Save Configuration to NVRAM

Restore Defaults

Figure 3-6: System Manager: NVRAM Admin

      1. Firmware Upgrade

In the Firmware Upgrade screen, the system can be configured to download and boot from a new image off the network. (Please refer to Chapter 5 when updating software)

Save the configuration to NVRAM and reset the switch. The image will load-up automatically after the switch resets.

      1. Reset

In this screen the user can reset (power cycle) the switch. This is primarily used to upgrade the firmware or restore defaults.

3.6 Port Manager

This page will allow access to the port parameters. The parameters available are as follows:

3.7 Address Manager

Any system, whose MAC address and the port number are listed in this screen, will not be purged from the system¡¦s forwarding table by the ageing process.

Add a new entry

Remove an exist entry

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).

Figure 3-11: Address Manager: Address Ageing

3.8 Spanning Tree

Spanning Tree can be enabled or disabled in this screen.

Enable: There are four other tunable parameters to be addressed.

Disable: Disable spanning tree algorithm on the system.

Figure 3-12: Spanning Tree: Bridge Settings

For the Port Settings options, you can specify spanning tree parameters for each port. These parameters include port priority and path cost.

Figure 3-13: Spanning Tree: Port Settings

3.9 VLAN Setup

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

Remove VLAN Group

Add VLAN Membership

Remove VLAN Membership

Figure 3-14: VLAN Setup: Membership

All untagged packets entering the switch will by default be tagged with the ID specified by the port¡¦s PVID. This screen allows you to specify the PVID for each port.

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 3-16: Port Mirroring

3.11 SNMP Management

The SNMP menu contains the following sub-menus:

      1. Community Table
      2. In the Community Table the administrator can create different community strings with customized access by choosing combinations of GET, SET and TRAP rights.

        Figure 3-17: SNMP Management: Community Table

      3. Host Table
      4. 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.

      5. Trap Setting

The SNMP Trap Setting allows for the setup of authentication traps.

Authentication traps

All hosts in community strings with TRAP privileges will be notified when a trap condition occurs.

3.12 Statistics

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.

When all of the variables are set, click Draw.
