Design Features
Design Features
VLAN
VLAN is short for Virtual Local Area Network, and is generally dened 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 trafc 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-duplex 100Mbps 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-T
Ethernet networks to 100BASE-TX Fast Ethernet networks and to segment
10Mbps or 100Mbps network segments.
Auto-Negotiation
Auto-Negotiation provides 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-T selection, half- /
full-duplex mode operation, etc.)

Design Features

Full-Duplex
Full-Duplex transmission means that dedicated inbound and outbound channels
are established for bi-directional transmission of data. This allows the collision
detection mechanism (CSMA/CD) to be by-passed, thus decreasing transmission
delay normally caused by listening, collisions, and packet resends when operating
in half-duplex mode.
Store-and-Forward Switching
The Fast EtheRx Switch uses a packet-forwarding method called Store-and-
Forward, which minimizes the re-transmission of 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-duplex mode the Fast EtheRx Switch implements a collision-based
backpressure 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 the free-buffer queue has reached the pre-set minimum.
In full-duplex mode 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 the pre-set minimum.

Aging Time
The address-aging timer 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 specied 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 benet 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
Up to 4 Trunks
Up to 6 Trunks
Up to 8 Trunks
KNS1650/R 16 Port Switch
KNS2450/R 24 Port Switch
KNS3250/R 32 Port Switch
Each port based trunk can have between 2-4 trunk ports as members of the trunk.
MAC Address based trunks must have 4 trunk ports per trunk.

Kingston Switch Configuration Utility
Load Balancing Method
In a multiple link trunk, the links within a trunk should have an equal amount of
trafc in order to achieve maximum efciency. Thus, some sort of load balancing
amongst the links of a trunk must be deployed. The Kingston KNS1650/R, 2450/R,
and 3250/R switches support MAC address based and port based balancing
methods. Using these methods, any packet with a trunk destination received by the
switch can be forwarded to a proper trunk port. After choosing one method, the user
must specify the relative load-balancing mapping to complete the conguration of
the trunk port load balancing.
Trunk Selection, Trunk Port Assignment
Place checkmarks in the boxes of the desired trunk and check the desired trunk port
assignments per trunk.
Trunk: A Trunk is a group of Trunk Ports grouped together.
Port Based Trunk: Each Port Based Trunk may have 2, 3, or 4 Trunk Ports.
MAC Address Based Trunk: Each MAC Address Based Trunk must contain 4
Ports.
Trunk Ports: A port assigned to a Trunk. The Trunk Ports are setup in groups of 4
and must be selected based on the groups. For example, Trunk 1 can only contain
Trunk Ports 1, 2, 3, or 4.
Load Balancing Mapping - MAC Address Based
When the switch receives a packet with a trunk destination, it will automatically
forward the packet to a trunk port based on the source MAC address (SA) and
destination MAC address (DA) of the packet. The device uses two bits from SA
and DA to map to four trunk ports.
The user can select which two bits should be used for mapping:
[1:0]
[3:2]
[5:4]
[7:6]
Uses bit 1 and 0 for mapping.
Uses bit 3 and 2 for mapping.
Uses bit 5 and 4 for mapping.
Uses bit 7 and 6 for mapping.
Each MAC Address contains 6 bytes of data, the last byte is taken from the source
MAC address (SA) and the last byte from the destination MAC address (DA). Each
byte contains 8 bits of data and the user can determine which two bits of the last
byte are used to map the trunk port. See the example on the following page:

Last byte of destination MAC address (DA) 51
The mapping rule is described below:
1. The two bits selected by the user for mapping will result in an odd or even value
assignment.
Exclusive Or (XOR) Values

For example, if the user species bit 1 and 0 for mapping and Trunk 2 is assigned,
the packets would be sent to the third Trunk Port of Trunk 2 (which would be Port
7).

Load Balancing Mapping – Port Based
The port-based load balancing method is an explicit port assignment scheme. It
requires that all other ports are assigned to a specic link (trunk port) in the trunk.
When the switch receives a packet with a trunk destination, it will automatically
forward the packet to a trunk port based on the port it came from.
First select a trunk, then click its Port Based button on the right hand side of the
screen under Load Balancing Mapping. The Port Based Trunk Port Mapping for
Trunk x window will appear as shown below.
Click the radio buttons to map each port to one of the trunk ports. All assignments
must be completed before it will allow you to close the window. After that, the
status will display ‘ok’ on the right side of the Port Based button. If the status ‘not
yet’ is displayed, then the load-balancing mapping has not been completed.

VLAN
This window allows users to dene VLAN membership by groups of device ports.
Any individual port or trunk can be a member of a VLAN group. AVLAN group is
basically a broadcast domain, but any port/trunk is not limited to belonging to only
one VLAN group. The forwarding rule is that packets from the source port/trunk
will only be forwarded to a destination port/trunk within the same VLAN group.
That is, a broadcast/multicast packet will be forwarded to all ports/trunks within
the same VLAN group(s) of the source port/trunk except the source port/trunk
itself. Unicast packets will be forwarded to the destination port/trunk only if the
destination port/trunk is in the same VLAN group as the source port/trunk.
Flood Control
Within a VLAN, the ood control function is provided to decide what to do with
incoming unicast packets with unknown destination MAC addresses.
Enable: Packets received with an unknown unicast destination address (DA)
will be forwarded to the specied out-link in the same VLAN group.
But if the source port (trunk) belongs to more than one VLAN
group, then the packet will only be forwarded to one of the out-
links.

Disable:
This option is selected by default. Packets received with an
unknown unicast destination address (DA) will be forwarded
to all ports (except the receiving port) within the same VLAN groups
that the received port (trunk) belongs to.
Flood control is available only when at least one VLAN group is assigned. And the
out-link port must be assigned when ood control is enabled for proper operation.
When ood control is enabled, each VLAN group must choose a member as its
out-link. If some VLAN groups have overlapped members, one of these members
should be chosen as the out-link. If a port (or trunk) belongs to more than one
VLAN group, packets that it receives with an unknown destination address (DA)
will only be forwarded to one of the out-links of those VLAN groups that it
belongs to.
VLAN Group
The list box shows all dened VLAN groups of the system, and each row is a
group. Any individual port or trunk can be a member of a VLAN group, and each
group comprises at least two members. One of the members is to be chosen as its
out-link. If ood control is disabled, the Out-link column will not appear.
To remove the current highlighted group, press the Delete button. Press the Add
button to add a new group. To modify settings, select the Modify button or
double click the current highlighted group to modify its content. While adding or
modifying a VLAN group, the dialog Modify the VLAN Group (or Add a New
VLAN Group) as below will popup for user to specify its content.

The group count is not limited. Users can specify n VLAN groups or even more
groups for any n (n=number of ports on your switch) port switch. But note that
after writing to the device, only the information of the rst n/2 added VLAN
groups can be read back from the device of n port switch.
Note: Once at least one VLAN group has been added, the system will automatically
gather all un-selected members as an implicit VLAN group. Users are recommended
to explicitly assign all groups they need, although they know that there exists an
implicit VLAN group.
Group Name: Create a group name up to 8 characters long.
Individual Port / Trunk: Both individual ports and trunks can be the members of
a VLAN group. All light checkboxes are qualied members of a VLAN. At least
two members must be selected to create a VLAN group.
Out-link Selection: If ood control is enabled, one port or trunk should be chosen
as the out-link of this VLAN group. Click on the button to the right of ‘Out-Link
Selection’ to bring up the popup window.

Explicit Address Table Page
The address table of the switch uses address learning (dynamic) or manual entry
(static). Static entries are added to the address table of the device in this window.
Static address entries are not aged or updated by the switch’s address learning.
Explicit Address Table
The list box displays all explicit (static) entries for the address table. Each row is
an entry for a MAC address to an individual port or a trunk. There are a total of 10
static addresses that can be assigned to Port 1 – 8, Port 9-16, Port 17 – 24, and Port
25 – 32 group, respectively.
Pressing the Delete button will remove the entry which is currently highlighted, or
press the Add button to add a new entry.
Note: Normally, the device has a static entry capacity of 10 per each group. Each
group consists of 8 consecutive ports and 2 trunks, that is, Port 1-8 and Trunk
1-2 belong to a group, Port 9-16 and Trunk 3-4 belong to another group, ...etc.
However, if a static address is assigned for Trunk 3-8, it will occupy an entry for
all groups, not just the group it belongs to. That is, if there is any static address
assigned for Trunk 3-8, it will reduce the entry capacity of each group. In the Add a
new entry of Explicit Address Table window, ports and trunks are grayed out when
there is no capacity to place a static entry for them.

UTP Ports use RJ-45 Unshielded Twisted Pair (UTP) cabling. RJ-45 modular
plugs and their pin numbers and wiring assignments are listed below. Twisted-
Pair cables can be wired with either Straight-Through or Crossover pin assign-
ments. Both wiring schemes are mentioned in “Appendix B Cabling Guidelines”
for reference in creating a twisted-pair cable.

UTP Cable Type
When installing network cables, the following table shows appropriate cabling
guidelines for 100BASE-TX Fast Ethernet architecture.
Table B-1 Network Cable Guidelines
(NOTE: All UTP cables come in both solid and stranded lament. Solid
lament cables are more rigid and usually intended for trunk cabling.
Stranded lament cables are more pliable and generally targeted for patch
cables. For proper termination, use the correct RJ-45 connector, as they
differ for each type of cable.)
UTP Cable Wiring
UTP cables are wired based on one of two standard pin congurations: Straight-
Through and Cross-Over. 100BASE-TX uses only Category-5 UTP cables with
four pairs of wire as illustrated below in Tables B-2 and B-3.

UTP Cable Wiring Standards
There are two governmental agencies: the Electronic Industry Association (EIA)
and the Telecommunications Industry Association (TIA), which set the standard
for all cable wiring requirements for commercial buildings.
With the advent of 100Mb/s networking products, it is best to use higher quality
CAT 5 cables like Belden or Helix as well as CAT 5-compliant patch panels, patch
cables, and connectors while following the EIA/TIAwiring standards. 100 W UTP
CAT 5 type cables use 4-pair UTP wiring.
Refer to the illustrations below for 4-pair wiring using either T568A (Fig. B-1) or
T568B (Fig. B-2) wiring standards. Both T568A and T568B wiring is compatible
with 10BASE-T and 100BASE-TX and require no special congurations, but for
premise wiring, stick to one wiring standard. Mixing T568A and T568B wiring
schemes may cause or lead to potential problems.

UTP Cable Rating Codes
UTP cables meet different UL-NEC requirements based on cable-jacket quality.
Below is an explanation of the rating codes for each cable type.
UL – The National Electrical Code (NEC), published by the National Fire
ProtectionAssociation (NFPA), details advisory safety considerations for electrical
wiring. NEC Article 800 Communications Cables are manufactured to meet these
different cable types.
1. CMP – Cables meeting type CMP requirements are suitable for installation in
ducts and plenums without the use of conduit. These cables are designed for re
resistance and low-smoke producing characteristics.
2. CMR – Riser type cables are engineered to prevent the spread of re from oor
to oor and are suitable for vertical shaft applications.
3. CM – Cables for general building wiring. CM cables are used in areas other
than plenums and risers. These cables are resistant to the spread of re and pass
the UL 1581Vertical Tray Flame Test.
4. MP, MPR & MPP – Within Article 800, the Multi-purpose Cables Category
allows conditional substitutions between different cable types & are restricted
by number, AWG size and stranding of the cable conductors.
Terms You Should Be Familiar With
1. BACKBONE WIRING – The physical/electrical interconnections between
telecommunications closets and equipment rooms.
2. COMPLIANCE – A wiring device that meets all characteristics of a standard
is said to be in compliance with that standard.
3. PREMISE WIRING – The entire wiring system on the premises especially
the supporting wiring that connects the communications outlets to the network
interface jack.
4. NEAR-END CROSSTALK (NEXT) – In wires packed together within a
cable, the signals generated at one end of the link can ush out the weaker
signals coming back from the recipient.
