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.
2.4 Port Statistics Port Statistics function will let you to see the TX/RX packet counters for each port. Clear Counters button will clear all packet counters to 0. Refresh button will get port statistics again. You can drill down into more detailed port statistics by clicking the Port number.
The table shown below provides a description for each column. UnicastPkts Number of good unicast packets transmitted. MulticastPkts Number of good multicast packets transmitted. BroadcastPkts Number of good broadcast packets transmitted.
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 disabled automatically.
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.
Below is an example page where the Administrator has set Ports1-12 to VLAN Group2 after clicking the Create button. There now exists a VLAN group No.2 with member Ports1-12. When group No.2 was created, all the members in group No.1 are removed ensure correct operation of the VLAN function.
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.
2.5.2 Edit Port-Based VLAN Groups To edit the current port-based VLAN group, first select the group (e.g. group No. 3) that you want to edit. To add Port7 & Port8 as members, select these ports and click the Apply button to activate the setting. The following figure shows the latest configuration for the selected group (e.g. No.3).
2.6 802.1Q VLAN IEEE 802.1q (tag-based) VLAN’s can add or strip 802.1q tags based on your parameters set for each transmitting port. Select the 802.1Q VLAN menu to activate the following page where this function can be configured. Currently the switch supports up to 32 tag-based VLAN groups for manual entry. The following pages will described in detail how to configure this feature.

(Any existing tag-based VLAN entries will be retained although tag-based VLAN functions will be disabled. Any retained port-based VLAN entries will auto enable.
2.6.2 802.1Q VLAN Port Configuration Click the Port number to configure the port for 802.1q VLAN. The following figure shows the 802.1Q VLAN Port Configuration page by port. (e.g. Port10) You can select an individual port for configuring the 802.1q settings in the following fields: ¾ ¾ ¾ PVID – enter a valid VLAN ID(1-4094), the PVID must be one of the existing VLAN group ID. UnTag Frame – Accept or drop incoming untagged frames. Tag Frame – Accept or drop incoming tagged frames.
2.6.3 802.1Q VLAN Config The following figure displays the add/delete/edit function for 802.1q VLAN entries. Each VLAN entry has 3 parameters, VID, Tag Members and UnTag Members to be assigned. After selecting the Create New VLAN, the figure shown as below will display: ¾ ¾ VID – a unique VLAN ID, range is from 1 to 4094 Tag Members & UnTag Members – Click the U/T icon to switch between Non Member, Tag Member or Untag Member.
Here is an example on how to configure the 802.1q VLAN. Now there are four existing 802.1q VLAN entries shown as below. Note: You can delete 802.1q VLAN entries via the selecting the Vlan from the dropdown list and (e.g. VID = 200), then click the Remove This VLAN button to perform the deletion. Note the 802.1q VLAN table now shows the following entries: The VID entry (VID=200) is successfully deleted.
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 make the required changes and click the Apply button : Port 17 and Port18 are selected to be the tag members of this group.
2.7 Trunking The GSS-24T2SFP web smart switch supports MAC-based trunking. This 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 GSS-24T2SFP web smart switch allows four trunk groups that can accommodate up to eight trunk members in each group. A port in one trunk group cannot be a member of another trunk simultaneously.
2.7.1 Trunking Rules The following rules determine your configuration 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 the Mirror function.
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 returned to their previous state. The following 3 figures show that the settings of a port while in a trunk group can be reverted back to normal once not in the trunk group any more.
