4 Design Features

Design Features

VLAN

VLAN is short for Virtual Local Area Network, and is generally de ned as a broadcast domain. It can be viewed as a group of end nodes which can communicate with each other even though they may be located on different physical network segments.

The Fast EtheRx switch provides a simple solution to protect your network against broadcast storming by creating segments based on Layer 2 Ethernet information. As a result, each group of stations connected to a seperate segmented port form an isolated Broadcast Domain. In a switched network environment, a broadcast packet or an unknown destination MAC address packet will broadcast to ALL ports, which can decrease the entire network system performance dramatically. By grouping ports into VLANs, broadcast packets will only be sent to the ports within the same VLAN without effecting the traf c of the ports outside of the VLAN. Broadcast sharing ports can be used to connect servers and other common services, such as Internet access, that are used by all the stations connected to the different segmented ports.

Typically users are grouped according to similar characteristics such as a common business function or a common protocol. A single switch may have several independent VLANs within it.

Link Trunking

Link trunking is basically a method of treating multiple physical links as a single logical link. By grouping ports into a trunk, you can increase the available bandwidth between switches or servers. Multiple lower speed links can be grouped into a single higher speed link. For example, four full-duplex100Mbps link, such as ports 1 through 4, can be grouped as a single 800Mbps link as Trunk 1.

Switching Function

The Fast EtheRx Switch is basically designed to bridge Standard 10BASE-TEthernet networks to100BASE-TXFast Ethernet networks and to segment 10Mbps or 100Mbps network segments.

Auto-Negotiation

Auto-Negotiationprovides the means of automatically establishing a link by detecting the link capabilities of the connected device on the network to select the best operational mode available (i.e.100BASE-TX/10BASE-Tselection,half- /full-duplexmode operation, etc.)

Kingston Technology Company

KNS3250/R User’s Guide - Rev. A00

Design Features

5

Full-Duplex

Full-Duplextransmission means that dedicated inbound and outbound channels are established forbi-directionaltransmission of data. This allows the collision detection mechanism (CSMA/CD) to beby-passed,thus decreasing transmission delay normally caused by listening, collisions, and packet resends when operating inhalf-duplexmode.

Store-and-ForwardSwitching

The Fast EtheRx Switch uses a packet-forwardingmethod calledStore-and-Forward, which minimizes there-transmissionof faulty data packets. This means that the Fast EtheRx Switch can store the incoming frame in an internal buffer and check the packet for errors before sending it out to the destination port. If the frame does contain errors, it will be discarded and then retransmitted.

Flow Control

In half-duplexmode the Fast EtheRx Switch implements acollision-basedbackpressure ow control mechanism that reduces the risk of data loss at congested ports. This is accomplished by forcing a collision with the data frames on all ports once thefree-bufferqueue has reached thepre-setminimum.

In full-duplexmode the Fast EtheRx Switch implements the IEEE 802.3x ow control mechanism. This is accomplished by sending a PAUSE packet on a port when the number of buffers allocated to this port exceeds thepre-setminimum.

Device Con guration Properties

System

Parameters adjusted in this window will control overall system performance.

SuperMAC

Enable: When a collision occurs, the port on which the collision occurs will perform a more aggressive back off algorithm of up to 3 slots.

Disable: This is the default setting, when a collision occurs, the device will perform the IEEE802.3 standard exponential backoff algorithm.

Aging Control

Enable: By default this option is enabled and set with an aging time of 255 seconds. When enabled, learned MAC addresses are discarded after the aging time has been reached. The aging time can be set between 1 and 510 seconds.

Disable: The Fast EtheRx Switch will retain the learned source MAC addresses for each port.

Only dynamically learned addresses will be aged. No explicit (static) entries will be aged out.

KNS3250/R Users Guide - Rev. A00

Kingston Switch Configuration Utility

Aging Time

The address-agingtimer is built in to the table aging process. The minimum time is 1 second and the maximum is 510 seconds. 255 is the default value, if the number exceeds 255 it must be an even number.

Broadcast Storm Control Threshold

The Broadcast storm control function limits the number of consecutive broadast packets for each port that has Broadcast Storm Control enabled. The broadcast packets are stored in the buffer and sent to the other ports one by one. In the buffer, when the number of stored broadcast packets exceeds the speci ed threshold, the device will discard the consecutive incoming broadcast packets until the number of stored broadcast packets is below the threshold. The assignable values are 16, 32, 48 and 64 with 64 being the default.

Trunk Assignment

The Kingston KNS1650R, KNS2450R, and KNS3250R switches support link aggregation/trunking. Trunking is a method of grouping multiple physical links as a single logical link. The bene t is to be able to group multiple lower speed links into one high speed link for bandwidth aggregation. For instance, four full duplex 100Mbps links, such as port 1-4,could be grouped into one 800Mbps link for Trunk 1. Trunking is most commonly used between the switch and server or between two switches.

See the chart below for the maximum number of trunks per switch:

Switch Model

Number of Trunks

 

 

KNS1650/R 16 Port Switch

Up to 4 Trunks

 

 

KNS2450/R 24 Port Switch

Up to 6 Trunks

 

 

KNS3250/R 32 Port Switch

Up to 8 Trunks

 

 

Each port based trunk can have between 2-4trunk ports as members of the trunk. MAC Address based trunks must have 4 trunk ports per trunk.
