4.3 Port Configuration
This function allows displaying each port’s status. The Link Status in the screen displays the current connection speed and
duplex mode; else this function will show down when the port is disconnected. Press the “Refresh” button to renew the
screen. The screen in Figure 4-4 appears.

4.4 Port Mirroring
This function provide to monitoring network traffic that forwards a copy of each incoming or outgoing packet from one port
of a network Switch to another port where the packet can be studied. It enables the manager to keep close track of switch
performance and alter it if necessary. The Port Mirroring screen in Figure 4-5 appears.
Figure 4-5 Mirror Setting screen
The page includes the following configurable data:
• Destination Port
• Sour ce Po rt
Configuring the port mirroring by assigning a source port from which to copy all packets and a destination port where those
packets will be sent.
#Note:
With the Chipset specification – the GSW-1602SF/2404SF port mirroring support RX (receive)
mode only - this mode will duplicate the data that send to the source and forward to the destination
port.
Use this option to select the port for monitored traffic. This is the port that your
network analyzer would be connected to – such as NAI Sniffer Pro or Ethereal.
Duplicate the data transmitted from the source port and forward it to the
Destination port.

4.5 VLANs
A Virtual LAN (VLAN) is a logical network grouping that limits the broadcast domain. It allows you to isolate network traffic
so only members of the VLAN receive traffic from the same VLAN members. Basically, creating a VLAN from a switch is
logically equivalent of reconnecting a group of network devices to another Layer 2 switch. However, all the network
devices are still plug into the same switch physically.
The GSW-1602SF/2404SF switch supports 802.1Q (tagged-based) and Port-Base VLAN setting in web management
page. In the default configuration, VLAN support is “802.1Q”.
Port-based VLAN
Port-based VLAN limit traffic that flows into and out of switch ports. Thus, all devices connected to a port are members of
the VLAN(s) the port belongs to, whether there is a single computer directly connected to a switch, or an entire
department.
On port-based VLAN.NIC do not need to be able to identify 802.1Q tags in packet headers. NIC send and receive normal
Ethernet packets. If the packet's destination lies on the same segment, communications take place using normal Ethernet
protocols. Even though this is always the case, when the destination for a packet lies on another switch port, VLAN
considerations come into play to decide if the packet is dropped by the Switch or delivered.
IEEE 802.1Q VLANs
IEEE 802.1Q (tagged) VLAN are implemented on the Switch. 802.1Q VLAN require tagging, which enables them to span
the entire network (assuming all switches on the network are IEEE 802.1Q-compliant).
VLAN allow a network to be segmented in order to reduce the size of broadcast domains. All packets entering a VLAN will
only be forwarded to the stations (over IEEE 802.1Q enabled switches) that are members of that VLAN, and this includes
broadcast, multicast and unicast packets from unknown sources.
VLAN can also provide a level of security to your network. IEEE 802.1Q VLAN will only deliver packets between stations
that are members of the VLAN. Any port can be configured as either tagging or untagging. The untagging feature of IEEE
802.1Q VLAN allows VLAN to work with legacy switches that don't recognize VLAN tags in packet headers. The tagging
feature allows VLAN to span multiple 802.1Q-compliant switches through a single physical connection and allows
Spanning Tree to be enabled on all ports and work normally.

4.5.1 VLAN Membership
This function group individual ports into a small “Virtual” network of their own to be independent of the other ports. The
screen in Figure 4-6 appears.
