1 Introduction The GSS-24T2SFP web smart switch is a high performance web-smart Layer 2 switch that provides users with switched 24 10/100/1000Mbps Ethernet ports, and 2 paired mini-GBIC ports. The mini GBIC ports are paired with ports 1 and 2 on the switch. This pairing is configured to ensure that fibre connections get higher priority over copper if both fibre and copper media exist. Single-mode or multi-mode fiber SFP transceivers can be utilized to provide high speed backbone connectivi

1.1 Managing The 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 the system through a web browser, or use the RS-232 cable to plug-in the console port (on the rear panel) to locally perform simple system configuration (CLI). The default IP and related settings for this switch are shown as following: IP address: 192.168.

2.3 About the Copper/Fiber Media Auto-Detection This switch provides an option to use either copper or fiber media for the first two combo ports - Port1 and Port2. This enables port configuration using either copper media or fiber media via use of the mini-GBIC ports and optional SFP (mini-GBIC) modules. The switch will automatically detect the media type that is plugged into the switch and configure the port as required. If both copper and fiber media are plugging-in, the fiber media has h

2.5 Port-Based VLAN Port-based VLAN divides the switches ports into different Virtual LAN domain groups. After setting up port -based VLAN, ports allocated into different VLAN groups can not access each other. This is like creating virtual switches that do not connect to each other. The VLAN initial setting page is shown as below: Of course, you need to click the Enable/Disable link text to enable/disable port-based VLAN. When port-based VLAN is enabled, the 802.1Q VLAN will be disa

Add Port-Based VLAN Groups To add a port-based VLAN group, select the Create New VLAN in VLAN NO dropdown of the Port-Based VLAN page shown as below: After selecting Create New VLAN, the page will change to the following: In the example page, VLAN NO will be auto assigned. The administrator simply needs to set VLAN Port Members. After completing the settings, press the Create button. The screen will then revert back to the VLAN initial settings page. The Cancel button can be used

2.5.1 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 to do the deletion. In this example after selecting the Remove This VLAN button, the resultant is all VLANs deleted, and the Default VLAN 1 - enabled. (see below) Now all ports are set to be members of VLAN group No.1. 17
