3.2.1 Local Console Management
You can manage the GSW-2416SF locally by connecting a VT100 terminal, or a personal computer or workstation with
terminal emulation software, to the Switch serial port. The terminal or workstation connects to the Switch serial port using a
null modem cable that has the appropriate connectors on each end.
This management method is ideal when:
- The network is unreliable.
- The Network Manager does not have direct network connection.
The serial port of the Switch default setting is set to 19200 baud using a character format of 8 data bits, no parity, and 1
stop bit.
Therefore, configure the terminal or workstation to use these settings before you log on to the GSW-2416SF. You can
change this default setting, if desired, after you log on.

VLAN Tag:
Tagged-based VLAN is an IEEE 802.1Q specification standard. Therefore, it is possible to create a VLAN across devices
from different switch venders. IEEE 802.1Q VLAN uses a technique to insert a "tag" into the Ethernet frames. Tag contains
a VLAN Identifier (VID) that indicates the VLAN numbers.
To set the outgoing frames are VLAN-Tagged frames or untagged.
Tag: outgoing frames with VLAN-Tagged.
UnTag: outgoing frames without VLAN-Tagged.
PVID:
Set the PVID that will be assigned to untagged traffic on a given port. This feature is useful for accommodating devices that
you want to participate in the VLAN but that don't support tagging. The switch each port allows user to set one PVID, the
range is 0~4095, default VLAN ID is 0. The PVID must as same as the VLAN ID that the port belong to VLAN group( See
chapter 5.3 – VLAN Setup), or the untagged traffic will be dropped.

5.3 VLAN Setup
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-2416SF switch supports Port-Base VLAN setting in web management page. In the default configuration, VLAN
support is “disable”.

6. SWITCH OPERATION
6.1 Address Table
The Switch is implemented with an address table. This address table composed of many entries. Each entry is used to
store the address information of some node in network, including MAC address, port no, etc. This information comes
from the learning process of Ethernet Switch.
6.2 Learning
When one packet comes in from any port. The Switch will record the source address, port no. And the other related
information in address table. This information will be used to decide either forwarding or filtering for future packets.
6.3 Forwarding & Filtering
When one packet comes from some port of the Ethernet Switching, it will also check the destination address besides
the source address learning. The Ethernet Switching will lookup the address-table for the destination address. If not
found, this packet will be forwarded to all the other ports except the port which this packet comes in. And these ports
will transmit this packet to the network it connected. If found, and the destination address is located at different port
from this packet comes in, the Ethernet Switching will forward this packet to the port where this destination address is
located according to the information from address table. But, if the destination address is located at the same port with
this packet comes in, then this packet will be filtered. Thereby increasing the network throughput and availability.
6.4 Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and Forward Ethernet Switching stores the
incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets
occurrence, it is the best choice when a network needs efficiency and stability.
The Ethernet Switch scans the destination address from the packet-header, searches the routing table provided for
the incoming port and forwards the packet, only if required. The fast forwarding makes the switch attractive for
connecting servers directly to the network, thereby increasing throughput and availability. However, the switch is most
commonly used to segment existing hubs, which nearly always improves overall performance. An Ethernet Switching
can be easily configured in any Ethernet network environment to significantly boost bandwidth using conventional
cabling and adapters.
Due to the learning function of the Ethernet switching, the source address and corresponding port number of each
incoming and outgoing packet are stored in a routing table. This information is subsequently used to filter packets
whose destination address is on the same segment as the source address. This confines network traffic to its
respective domain, reducing the overall load on the network.
The Switch performs "Store and forward" therefore, no error packets occur. More reliably, it reduces the
re-transmission rate. No packet loss will occur.
6.5 Auto-Negotiation
The STP ports on the GSW-2416SF Switch have built-in “Auto-negotiation”. This technology automatically sets the
best possible bandwidth when a connection is established with another network device (usually at Power On or Reset).
This is done by detect the modes and speeds at the second of both device is connected and capable of, Both
10Base-T and 100Base-TX devices can connect with the port in either Half- or Full-Duplex mode. 1000Base-T can be
only connected in Full-duplex mode.

7.TROUBLESHOOTING
This chapter contains information to help you solve problems. If the Switch is not functioning properly, make sure the
Ethernet Switch was set up according to instructions in this manual.
The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the Switch.
Some stations cannot talk to other stations located on the other port
Solution:
Please check the VLAN, port trunking function that may introduce this kind of problem.
Performance is bad
Solution:
Check the full duplex status of the Ethernet Switch. If the Ethernet Switch is set to full duplex and the partner is set to
half duplex, then the performance will be poor.
100Base-TX port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to
change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
Why the Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the switch Try another port on the Switch Make sure the cable is installed properly Make
sure the cable is the right type Turn off the power. After a while, turn on power again.
