Chapter 4
Switch Operation
Address Table
The Industrial Gigabit Ethernet Switch is implemented with an address table. This address table is 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 is automatically obtained by the Industrial Gigabit Ethernet Switch.
Learning
When one packet comes in from any port. The Industrial Gigabit Ethernet Switch will record the source address,and port number, and the other related information in address table. This information will be used to decide either forwarding or filtering for future packets.
Forwarding & Filtering
When one packet comes from some port of the Industrial Fast Ethernet Switch, it will also check the destination address besides the source address. The Industrial Fast
Ethernet Switch 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 from which this packet comes in. And these ports will transmit this packet to the network it is connected to. If found, and the destination address is located at a different port from where this packet comes in, the Industrial Fast Ethernet Switch will forward this packet to the port where this destination address is located, according to the
GE-DSG-8 DSGH-5 and 8 Ethernet Switch User Manual 15
Chapter 4: Switch Operation information from address table. But, if the destination address is located at the same port from where this packet comes in, then this packet will be filtered. Thereby increasing the network throughput and availability.
Store-and-Forward
Store-and-Forward is one type of packet-forwarding techniques. A Store-and-
Forward Industrial Switch stores the incoming frame in an internal buffer, do the complete error checking before transmission. Therefore, no error packets can occur.
This is the best choice when a network needs efficiency and stability.
The Industrial Fast Ethernet Switch scans the destination address from the packetheader, 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 improve overall performance. An Ethernet Switch 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 Industrial Fast Ethernet Switch, 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 Industrial Fast Ethernet Switch performs "Store-and-Forward" therefore, no error packets occur. More reliably, it reduces the re-transmission rate. No packet loss will occur.
Auto-negotiation
The STP ports on the Industrial Fast Ethernet 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 detecting 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.

Troubleshooting
This chapter contains information to help you solve common issues. If the Industrial
Gigabit Ethernet Switch is not functioning properly, make sure the Industrial Gigabit
Ethernet Switch was set up according to instructions in this manual.
The per port LED is not lit
Solution:
Check the cable connection of the Industrial Gigabit Ethernet Switch.
Performance is bad
Solution:
Check the speed duplex mode of the partner device. The Industrial Gigabit Ethernet
Switch is run at Auto-negotiation mode and if the partner is set to half duplex, then the performance will be poor.
Per port 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 Industrial Gigabit Ethernet Switch doesn't connect to the network
Solution:
Check per port LED on the Industrial Gigabit Ethernet Switch. Try another port on the
Industrial Gigabit Ethernet Switch Make sure the cable is installed properly Make sure the cable is the right type Turn off the power. After a minnute, turn on the power again.
