priority for the ports. Use the Port Priority Configuration Menu screen to
change the values within the screen.

The priority configuration sets the IEEE 802.1p priority function of the
system. PLANET GSW-800S has 4

priority queues per port. Each
frame can be sent via high or low priority queue depending on the
priority setting and the tag value of it (see the Figure 3-14).

Use the "Arrow" key to move the highlight to the selection and press the
"Space Bar" key to toggle back and forth between the options. Pressing
"Enter" key for confirmation.

3.2.9 Port Statistics

For those selected port, this function could provide you with an
individual statistical counter (see the Figure 15). The update rate is 12
seconds. It is a useful page for administrator to monitor each port’s
usage condition. Also, it is helpful to troubleshooting network problems.
Please note that the updating rate is defined in System Configuration
menu.

3.2.10 Restart

The Restart Menu is accessed from the Main Menu. The System
Restart Screen, as shown below, allows you to view or change the
<Factory default> or <Restart> values. Use the "Arrow" keys to move
the highlight to <Factory default> and press the "Enter" key. Then you
will clear all the configuration data and put the Switch into factory
default state. The switch then restarted.

If you choose the <Restart> function, you will perform a reset of the
switch.

4. SWITCH OPERATION

4.1 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.

4.2 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.

4.3 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

4.4 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. A 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.

4.5 Auto-Negotiation

The STP ports on the 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.

5. TROUBLESHOOTING

This chapter contains information to help you solve problems. If
Giga 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 Giga Switch

Some stations can not talk to other stations located on
The other port

Solution:

The address table may contain older information than of the
address table of that node. Please power down to refresh the
address information, please also check VLAN configuration.

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.
