CERIO software core : cen_v3.0

Slot Time : Slot time is in the range of 9~1489 and set in unit of microsecond. The
default value is 9 microsecond.
Slot time is the amount of time a device waits after a collision before retransmitting a
packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of time a
station waits before sending a packet on the LAN. For a sender and receiver own right of
the channel the shorter slot time help manage shorter wait time to re-transmit from
collision because of hidden wireless clients or other causes. When collision sources can
be removed sooner and other senders attempting to send are listening the
channel(CSMA/CA) the owner of the channel should continue ownership and finish their
transmission and release the channel. Then, following ownership of the channel will be
sooner for the new pair due to shorter slot time. However, when long duration of existing
collision sources and shorter slot time exist the owners might experience subsequent
collisions. When adjustment to longer slot time can’t improve performance then RTS/CTS
could supplement and help improve performance.

ACK Timeout : ACK timeout is in the range of 1~372 and set in unit of microsecond.
The default value is 64 microsecond.
All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by
receiving radio. The transmitter will resend the original packet if correspondent ACK failed
to arrive within specific time interval, also refer to as “ACK Timeout”.
ACK Timeout is adjustable due to the fact that distance between two radio links may vary
in different deployment. ACK Timeout makes significant influence in performance of long
distance radio link. If ACK Timeout is set too short, transmitter will start to “Resend”
packet before ACK is received, and throughput become low due to excessively high
re-transmission.
CERIO software core : cen_v3.0
ACK Timeout is best determined by distance between the radios, data rate of average
environment. The Timeout value is calculated based on round-trip time of packet with a
little tolerance, So, if experiencing re-transmissions or poor performance the ACK
Timeout could be made longer to accommodate.
Slot Time and ACK Timeout settings are for long distance links. It is important to
tweak settings to achieve the optimal result based on requirement.

Beacon Interval : Beacon Interval is in the range of 40~3500 and set in unit of
millisecond. The default value is 100 msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame,
called “Beacon”. Beacon is broadcast to all the stations, provides the basic information of
AP such as SSID, channel, encryption keys, signal strength, time stamp, support data
rate.
All the radio stations received beacon recognizes the existence of such AP, and may
proceed next actions if the information from AP matches the requirement. Beacon is sent
on a periodic basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated
overhead, but that will likely delay the association and roaming process because stations
scanning for available access points may miss the beacons. You can decrease the
beacon interval, which increases the rate of beacons. This will make the association and
roaming process very responsive; however, the network will incur additional overhead
and throughput will go down.

DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.
DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless
stations, which support power saving mode, when to wake up to receive multicast frame.
DTIM is necessary and critical in wireless environment as a mechanism to fulfill
power-saving synchronization. A DTIM interval is a count of the number of beacon frames
that must occur before the access point sends the buffered multicast frames.
For
instance, if DTIM Interval is set to 3, then the Wi-Fi clients will expect to receive a
multicast frame after receiving three Beacon frame. The higher DTIM interval will help
power saving and possibly decrease wireless throughput in multicast applications.

RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347
byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible
collisions due to hidden wireless clients. RTS in AP will be enabled automatically if the
CERIO software core : cen_v3.0
packet size is larger than the Threshold value. By default, RTS is disabled in a normal
environment supports non-jumbo frames.

Short Preamble : By default, it’s “Enable”. To Disable is to use Long 128-bit Preamble
Synchronization field.
The preamble is used to signal "here is a train of data coming" to the receiver. The short
preamble provides 72-bit Synchronization field to improve WLAN transmission efficiency
with less overhead.

IGMP Snooping : the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to listen in on the IGMP conversation
between hosts and routers. By listening to these conversations the switch maintains a
map of which links need which IP multicast streams. Multicasts may be filtered from the
links which do not need them and thus controls which ports receive specific multicast
traffic.

DFS : Is IEEE802.11H With DFS(Dynamic Frequency Selection) enabled, radio is
operating on one of the following channels, the wireless device uses DFS to monitor the
operating frequency and switch to another frequency or reduce power as necessary.
The maximum legal transmit power is greater for some 5 GHz channels than for others.
When the wireless device randomly selects a 5 GHz channel on which power is restricted,
the wireless device automatically reduces transmit power to comply with power limits for
that channel in that regulatory domain.

Greenfield : In wireless WLAN technology, greenfield mode is a feature of major
components of the 802.11n specification. The greenfield mode feature is designed to
improve efficiency by eliminating support for 802.11b/g devices in an all draft-n network.
In greenfield mode the network can be set to ignore all earlier standards.

WMM QoS : This affects traffic flowing from the access point to the client station.
Configuring QoS options consists of setting parameters on existing queues for different
types of wireless traffic. You can configure different minimum and maximum wait times
for the transmission of packets in each queue based on the requirements of the media
being sent. Queues automatically provide minimum transmission delay for Voice, Video,
multimedia, and mission critical applications, and rely on best-effort parameters for
traditional IP data.
As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher
priority for transmission (lower wait times for channel access), while other applications
CERIO software core : cen_v3.0
and traditional IP data which are less time-sensitive but often more data-intensive are
expected to tolerate longer wait times.

AC Type:
Queue
AC_BK
Background
Low
High throughput. Bulk data that requires maximum
throughput and is not time-sensitive is sent to this
queue (FTP data, for example).
AC_BE
Best Effort
Medium
Medium throughput and delay. Most traditional IP
data is sent to this queue.
AC_VI
Video
High
Minimum delay. Time-sensitive video data is
automatically sent to this queue.
AC_VO
Voice
High
Time-sensitive data like VoIP and streaming media
are automatically sent to this queue.

CWmin:Minimum Contention Window. This parameter is input to the algorithm that
determines the initial random backoff wait time ("window") for retry of a transmission.
The value specified here in the Minimum Contention Window is the upper limit (in
milliseconds) of a range from which the initial random backoff wait time is
determined.。

CWmax:Maximum Contention Window. The value specified here in the Maximum
Contention Window is the upper limit (in milliseconds) for the doubling of the random
backoff value. This doubling continues until either the data frame is sent or the
Maximum Contention Window size is reached. Once the Maximum Contention
CERIO software core : cen_v3.0
Window size is reached, retries will continue until a maximum number of retries
allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31, 63, 127, 255,
511, or 1024. The value for "cwmax" must be higher than the value for "cwmin".。

AIFS:The Arbitration Inter-Frame Spacing Number specifies a wait time (in
milliseconds) for data frames。

TxOP Limit:Transmission Opportunity is an interval of time when a WME AP has
the right to initiate transmissions onto the wireless medium (WM). This value
specifies (in milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the
interval of time when the WMM AP has the right to initiate transmissions on the
wireless network.。

ACM bit:Admission Control Mandatory, ACM only takes effect on AC_VI and
AC_VO. When you do not click Checkbox, it means that the ACM is controlled by the
connecting AP. If you click Checkbox, it means that the Client is in charge。

No ACK policy bit:Acknowledgment Policy, WMM defines two ACK policies:
Normal ACK and No ACK. Click “Checkbox” indicates “No ACK”
When the no acknowledgement (No ACK) policy is used, the recipient does not
acknowledge received packets during wireless packet exchange. This policy is
suitable in the environment where communication quality is fine and interference is
weak. While the No ACK policy helps improve transmission efficiency, it can cause
increased packet loss when communication quality deteriorates. This is because
when this policy is used, a sender does not retransmit packets that have not been
received by the recipient.
When the Normal ACK policy is used, the recipient acknowledges each received
uncast packet.。

3.5 Configure Wireless Advanced Setup
The administrator can change the Slot Time, ACK Timeout, RTS threshold and fragmentation
threshold settings for the system. Please click on Wireless -> Advanced Setup and follow the
below setting.
CERIO software core : cen_v3.0

Slot Time : Slot time is in the range of 9~1489 and set in unit of microsecond. The
default value is 9 microsecond.
Slot time is the amount of time a device waits after a collision before retransmitting a
packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of time a
station waits before sending a packet on the LAN. For a sender and receiver own right of
the channel the shorter slot time help manage shorter wait time to re-transmit from
collision because of hidden wireless clients or other causes. When collision sources can
be removed sooner and other senders attempting to send are listening the
channel(CSMA/CA) the owner of the channel should continue ownership and finish their
transmission and release the channel. Then, following ownership of the channel will be
sooner for the new pair due to shorter slot time. However, when long duration of existing
collision sources and shorter slot time exist the owners might experience subsequent
collisions. When adjustment to longer slot time can’t improve performance then RTS/CTS
could supplement and help improve performance.

ACK Timeout : ACK timeout is in the range of 1~372 and set in unit of microsecond.
The default value is 64 microsecond.
All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by
receiving radio. The transmitter will resend the original packet if correspondent ACK failed
to arrive within specific time interval, also refer to as “ACK Timeout”.
ACK Timeout is adjustable due to the fact that distance between two radio links may vary
in different deployment. ACK Timeout makes significant influence in performance of long
distance radio link. If ACK Timeout is set too short, transmitter will start to “Resend”
packet before ACK is received, and throughput become low due to excessively high
re-transmission.
CERIO software core : cen_v3.0
ACK Timeout is best determined by distance between the radios, data rate of average
environment. The Timeout value is calculated based on round-trip time of packet with a
little tolerance, So, if experiencing re-transmissions or poor performance the ACK
Timeout could be made longer to accommodate.
Slot Time and ACK Timeout settings are for long distance links. It is important to
tweak settings to achieve the optimal result based on requirement.

Beacon Interval : Beacon Interval is in the range of 40~3500 and set in unit of
millisecond. The default value is 100 msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame,
called “Beacon”. Beacon is broadcast to all the stations, provides the basic information of
AP such as SSID, channel, encryption keys, signal strength, time stamp, support data
rate.
All the radio stations received beacon recognizes the existence of such AP, and may
proceed next actions if the information from AP matches the requirement. Beacon is sent
on a periodic basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated
overhead, but that will likely delay the association and roaming process because stations
scanning for available access points may miss the beacons. You can decrease the
beacon interval, which increases the rate of beacons. This will make the association and
roaming process very responsive; however, the network will incur additional overhead
and throughput will go down.

DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.
DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless
stations, which support power saving mode, when to wake up to receive multicast frame.
DTIM is necessary and critical in wireless environment as a mechanism to fulfill
power-saving synchronization.
A DTIM interval is a count of the number of beacon frames that must occur before the
access point sends the buffered multicast frames. For instance, if DTIM Interval is set to
3, then the Wi-Fi clients will expect to receive a multicast frame after receiving three
Beacon frame. The higher DTIM interval will help power saving and possibly decrease
wireless throughput in multicast applications.
CERIO software core : cen_v3.0

RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347
byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible
collisions due to hidden wireless clients. RTS in AP will be enabled automatically if the
packet size is larger than the Threshold value. By default, RTS is disabled in a normal
environment supports non-jumbo frames.

Short Preamble : By default, it’s “Enable”. To Disable is to use Long 128-bit Preamble
Synchronization field.
The preamble is used to signal "here is a train of data coming" to the receiver. The short
preamble provides 72-bit Synchronization field to improve WLAN transmission efficiency
with less overhead.

IGMP Snooping : the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to listen in on the IGMP conversation
between hosts and routers. By listening to these conversations the switch maintains a
map of which links need which IP multicast streams. Multicasts may be filtered from the
links which do not need them and thus controls which ports receive specific multicast
traffic.

DFS : Is IEEE802.11H With DFS(Dynamic Frequency Selection) enabled, radio is
operating on one of the following channels, the wireless device uses DFS to monitor the
operating frequency and switch to another frequency or reduce power as necessary.
The maximum legal transmit power is greater for some 5 GHz channels than for others.
When the wireless device randomly selects a 5 GHz channel on which power is restricted,
the wireless device automatically reduces transmit power to comply with power limits for
that channel in that regulatory domain.

Greenfield : In wireless WLAN technology, greenfield mode is a feature of major
components of the 802.11n specification. The greenfield mode feature is designed to
improve efficiency by eliminating support for 802.11b/g devices in an all draft-n network.
In greenfield mode the network can be set to ignore all earlier standards.

WMM QoS : This affects traffic flowing from the access point to the client station.
Configuring QoS options consists of setting parameters on existing queues for different
types of wireless traffic. You can configure different minimum and maximum wait times
for the transmission of packets in each queue based on the requirements of the media
being sent. Queues automatically provide minimum transmission delay for Voice, Video,
CERIO software core : cen_v3.0
multimedia, and mission critical applications, and rely on best-effort parameters for
traditional IP data.
As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher
priority for transmission (lower wait times for channel access), while other applications
and traditional IP data which are less time-sensitive but often more data-intensive are
expected to tolerate longer wait times.

CWmin:Minimum Contention Window. This parameter is input to the algorithm that
determines the initial random backoff wait time ("window") for retry of a transmission.
The value specified here in the Minimum Contention Window is the upper limit (in
milliseconds) of a range from which the initial random backoff wait time is
determined.。

CWmax:Maximum Contention Window. The value specified here in the Maximum
Contention Window is the upper limit (in milliseconds) for the doubling of the random
backoff value. This doubling continues until either the data frame is sent or the
Maximum Contention Window size is reached. Once the Maximum Contention
Window size is reached, retries will continue until a maximum number of retries
allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31, 63, 127, 255,
511, or 1024. The value for "cwmax" must be higher than the value for "cwmin".。

AIFS:The Arbitration Inter-Frame Spacing Number specifies a wait time (in
milliseconds) for data frames。

TxOP Limit:Transmission Opportunity is an interval of time when a WME AP has
the right to initiate transmissions onto the wireless medium (WM). This value
specifies (in milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the
interval of time when the WMM AP has the right to initiate transmissions on the
wireless network.。

ACM bit:Admission Control Mandatory, ACM only takes effect on AC_VI and
AC_VO. When you do not click Checkbox, it means that the ACM is controlled by the
connecting AP. If you click Checkbox, it means that the Client is in charge。

No ACK policy bit:Acknowledgment Policy, WMM defines two ACK policies:
Normal ACK and No ACK. Click “Checkbox” indicates “No ACK”
When the no acknowledgement (No ACK) policy is used, the recipient does not
acknowledge received packets during wireless packet exchange. This policy is
suitable in the environment where communication quality is fine and interference is
weak. While the No ACK policy helps improve transmission efficiency, it can cause
increased packet loss when communication quality deteriorates. This is because
when this policy is used, a sender does not retransmit packets that have not been
received by the recipient.
When the Normal ACK policy is used, the recipient acknowledges each received
uncast packet.。


MCS : This parameter represents transmission rate. By default (Auto) the fastest possible
transmission rate will be selected. You have the option of selecting the speed if
necessary.

Shout GI : Short Guard Interval, by default, it's “Enable”. it's can increase throughput.
However, it can also increase error rate in some installations, due to increased sensitivity
to radio-frequency reflections. Select the option that works best for your installation.

Aggregation : By default, it's “Enable”. To “Disable” to deactivated Aggregation.
A part of the 802.11n standard (or draft-standard). It allows sending multiple frames per
single access to the medium by combining frames together into one larger frame. It
creates the larger frame by combining smaller frames with the same physical source and
destination end points and traffic class (i.e. QoS) into one large frame with a common
MAC header.

Aggregation Frames : The Aggregation Frames is in the range of 2~64, default is 32. It
determines the number of frames combined on the new larger frame.

Aggregation Size : The Aggregation Size is in the range of 1024~65535, default is
50000. It determines the size (in Bytes) of the larger frame.
4.5 Configure Wireless Advanced Setup
The administrator can change the Slot Time, ACK Timeout, RTS threshold and fragmentation
threshold settings for the system. Please click on Wireless -> Advanced Setup and follow the
below setting.

Slot Time : Slot time is in the range of 9~1489 and set in unit of microsecond. The
default value is 9 microsecond.
CERIO software core : cen_v3.0
Slot time is the amount of time a device waits after a collision before retransmitting a
packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of time a
station waits before sending a packet on the LAN. For a sender and receiver own right of
the channel the shorter slot time help manage shorter wait time to re-transmit from
collision because of hidden wireless clients or other causes. When collision sources can
be removed sooner and other senders attempting to send are listening the
channel(CSMA/CA) the owner of the channel should continue ownership and finish their
transmission and release the channel. Then, following ownership of the channel will be
sooner for the new pair due to shorter slot time. However, when long duration of existing
collision sources and shorter slot time exist the owners might experience subsequent
collisions. When adjustment to longer slot time can’t improve performance then RTS/CTS
could supplement and help improve performance.

ACK Timeout : ACK timeout is in the range of 1~372 and set in unit of microsecond.
The default value is 64 microsecond.
All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by
receiving radio. The transmitter will resend the original packet if correspondent ACK failed
to arrive within specific time interval, also refer to as “ACK Timeout”.
ACK Timeout is adjustable due to the fact that distance between two radio links may vary
in different deployment. ACK Timeout makes significant influence in performance of long
distance radio link. If ACK Timeout is set too short, transmitter will start to “Resend”
packet before ACK is received, and throughput become low due to excessively high
re-transmission.
ACK Timeout is best determined by distance between the radios, data rate of average
environment. The Timeout value is calculated based on round-trip time of packet with a
little tolerance, So, if experiencing re-transmissions or poor performance the ACK
Timeout could be made longer to accommodate.
Slot Time and ACK Timeout settings are for long distance links. It is important
to tweak settings to achieve the optimal result based on requirement.

Beacon Interval : Beacon Interval is in the range of 40~3500 and set in unit of
millisecond. The default value is 100 msec. Access Point (AP) in IEEE 802.11 will send out a
special approximated 50-byte frame, called “Beacon”. Beacon is broadcast to all the stations,
provides the basic information of AP such as SSID, channel, encryption keys, signal strength,
time stamp, support data rate.
CERIO software core : cen_v3.0
All the radio stations received beacon recognizes the existence of such AP, and may
proceed next actions if the information from AP matches the requirement. Beacon is sent
on a periodic basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated
overhead, but that will likely delay the association and roaming process because stations
scanning for available access points may miss the beacons. You can decrease the
beacon interval, which increases the rate of beacons. This will make the association and
roaming process very responsive; however, the network will incur additional overhead
and throughput will go down.

DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.
DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless
stations, which support power saving mode, when to wake up to receive multicast frame.
DTIM is necessary and critical in wireless environment as a mechanism to fulfill
power-saving synchronization.
A DTIM interval is a count of the number of beacon frames that must occur before the
access point sends the buffered multicast frames. For instance, if DTIM Interval is set to
3, then the Wi-Fi clients will expect to receive a multicast frame after receiving three
Beacon frame. The higher DTIM interval will help power saving and possibly decrease
wireless throughput in multicast applications.

RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347
byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible
collisions due to hidden wireless clients. RTS in AP will be enabled automatically if the
packet size is larger than the Threshold value. By default, RTS is disabled in a normal
environment supports non-jumbo frames.


Shout GI : Short Guard Interval, by default, it's “Enable”. it's can increase throughput.
However, it can also increase error rate in some installations, due to increased sensitivity
to radio-frequency reflections. Select the option that works best for your installation.

Aggregation : By default, it's “Enable”. To “Disable” to deactivated Aggregation.
A part of the 802.11n standard (or draft-standard). It allows sending multiple frames per
single access to the medium by combining frames together into one larger frame. It
creates the larger frame by combining smaller frames with the same physical source and
destination end points and traffic class (i.e. QoS) into one large frame with a common
MAC header.


determines the number of frames combined on the new larger frame.

Aggregation Size : The Aggregation Size is in the range of 1024~65535, default is
50000. It determines the size (in Bytes) of the larger frame.
5.7 Configure Wireless Advanced Setup
The administrator can change the Slot Time, ACK Timeout, RTS threshold and fragmentation
threshold settings for the system. Please click on Wireless -> Advanced Setup and follow the
below setting.
CERIO software core : cen_v3.0

Slot Time : Slot time is in the range of 9~1489 and set in unit of microsecond. The
default value is 9 microsecond.
Slot time is the amount of time a device waits after a collision before retransmitting a
packet. Reducing the slot time decreases the overall back-off, which increases
throughput. Back-off, which is a multiple of the slot time, is the random length of time a
station waits before sending a packet on the LAN. For a sender and receiver own right of
the channel the shorter slot time help manage shorter wait time to re-transmit from
collision because of hidden wireless clients or other causes. When collision sources can
be removed sooner and other senders attempting to send are listening the
channel(CSMA/CA) the owner of the channel should continue ownership and finish their
transmission and release the channel. Then, following ownership of the channel will be
sooner for the new pair due to shorter slot time. However, when long duration of existing
collision sources and shorter slot time exist the owners might experience subsequent
collisions. When adjustment to longer slot time can’t improve performance then RTS/CTS
could supplement and help improve performance.

ACK Timeout : ACK timeout is in the range of 1~372 and set in unit of microsecond.
The default value is 64 microsecond.
All data transmission in 802.11b/g request an “Acknowledgement” (ACK) send by
receiving radio. The transmitter will resend the original packet if correspondent ACK failed
to arrive within specific time interval, also refer to as “ACK Timeout”.
ACK Timeout is adjustable due to the fact that distance between two radio links may vary
in different deployment. ACK Timeout makes significant influence in performance of long
distance radio link. If ACK Timeout is set too short, transmitter will start to “Resend”
packet before ACK is received, and throughput become low due to excessively high
re-transmission.
ACK Timeout is best determined by distance between the radios, data rate of average
environment. The Timeout value is calculated based on round-trip time of packet with a
little tolerance, So, if experiencing re-transmissions or poor performance the ACK
Timeout could be made longer to accommodate.
Slot Time and ACK Timeout settings are for long distance links. It is important to tweak
settings to achieve the optimal result based on requirement.
CERIO software core : cen_v3.0

Beacon Interval : Beacon Interval is in the range of 40~3500 and set in unit of
millisecond. The default value is 100 msec.
Access Point (AP) in IEEE 802.11 will send out a special approximated 50-byte frame,
called “Beacon”. Beacon is broadcast to all the stations, provides the basic information of
AP such as SSID, channel, encryption keys, signal strength, time stamp, support data
rate.
All the radio stations received beacon recognizes the existence of such AP, and may
proceed next actions if the information from AP matches the requirement. Beacon is sent
on a periodic basis, the time interval can be adjusted.
By increasing the beacon interval, you can reduce the number of beacons and associated
overhead, but that will likely delay the association and roaming process because stations
scanning for available access points may miss the beacons. You can decrease the
beacon interval, which increases the rate of beacons. This will make the association and
roaming process very responsive; however, the network will incur additional overhead
and throughput will go down.

DTIM Interval : The DTIM interval is in the range of 1~255. The default is 1.
DTIM is defined as Delivery Traffic Indication Message. It is used to notify the wireless
stations, which support power saving mode, when to wake up to receive multicast frame.
DTIM is necessary and critical in wireless environment as a mechanism to fulfill
power-saving synchronization.
a DTIM interval is a count of the number of beacon frames that must occur before the
access point sends the buffered multicast frames. For instance, if DTIM Interval is set to
3, then the Wi-Fi clients will expect to receive a multicast frame after receiving three
Beacon frame. The higher DTIM interval will help power saving and possibly decrease
wireless throughput in multicast applications.

RTS Threshold : TRTS Threshold is in the range of 1~2347 byte. The default is 2347
byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible
collisions due to hidden wireless clients. RTS in AP will be enabled automatically if the
packet size is larger than the Threshold value. By default, RTS is disabled in a normal
environment supports non-jumbo frames.
CERIO software core : cen_v3.0

Short Preamble : By default, it’s “Enable”. To Disable is to use Long 128-bit Preamble
Synchronization field.
The preamble is used to signal "here is a train of data coming" to the receiver. The short
preamble provides 72-bit Synchronization field to improve WLAN transmission efficiency
with less overhead.

IGMP Snooping : the process of listening to Internet Group Management Protocol (IGMP)
network traffic. The feature allows a network switch to listen in on the IGMP conversation
between hosts and routers. By listening to these conversations the switch maintains a
map of which links need which IP multicast streams. Multicasts may be filtered from the
links which do not need them and thus controls which ports receive specific multicast
traffic.

DFS : Is IEEE802.11H With DFS(Dynamic Frequency Selection) enabled, radio is
operating on one of the following channels, the wireless device uses DFS to monitor the
operating frequency and switch to another frequency or reduce power as necessary.
The maximum legal transmit power is greater for some 5 GHz channels than for others.
When the wireless device randomly selects a 5 GHz channel on which power is restricted,
the wireless device automatically reduces transmit power to comply with power limits for
that channel in that regulatory domain.

Greenfield : In wireless WLAN technology, greenfield mode is a feature of major
components of the 802.11n specification. The greenfield mode feature is designed to
improve efficiency by eliminating support for 802.11b/g devices in an all draft-n network.
In greenfield mode the network can be set to ignore all earlier standards.

Signal LED Thresholds : This function can setting RSSI number(1~99) to control signals
LED’s, The PS-200N-AX system will calculate for RSSI number and total of three LED’s
indicator, If LED's whole bright indicate signal is the strong.
The function only support Client Bridge + Repeater AP and WISP + Repeater AP
modes
 LED Indicator : Total of three LED’s, the LED1 RSSI number is Minimum
CERIO software core : cen_v3.0

WMM QoS : This affects traffic flowing from the access point to the client station.
Configuring QoS options consists of setting parameters on existing queues for different
types of wireless traffic. You can configure different minimum and maximum wait times
for the transmission of packets in each queue based on the requirements of the media
being sent. Queues automatically provide minimum transmission delay for Voice, Video,
multimedia, and mission critical applications, and rely on best-effort parameters for
traditional IP data.
As an Example, time-sensitive Voice & Video, and multimedia are given effectively higher
priority for transmission (lower wait times for channel access), while other applications
and traditional IP data which are less time-sensitive but often more data-intensive are
expected to tolerate longer wait times.


CWmin:Minimum Contention Window. This parameter is input to the algorithm that
determines the initial random backoff wait time ("window") for retry of a transmission.
The value specified here in the Minimum Contention Window is the upper limit (in
milliseconds) of a range from which the initial random backoff wait time is
determined.。

CWmax:Maximum Contention Window. The value specified here in the Maximum
Contention Window is the upper limit (in milliseconds) for the doubling of the random
backoff value. This doubling continues until either the data frame is sent or the
Maximum Contention Window size is reached. Once the Maximum Contention
Window size is reached, retries will continue until a maximum number of retries
allowed is reached. Valid values for the "cwmax" are 1, 3, 7, 15, 31, 63, 127, 255,
511, or 1024. The value for "cwmax" must be higher than the value for "cwmin".。

AIFS:The Arbitration Inter-Frame Spacing Number specifies a wait time (in
milliseconds) for data frames。

TxOP Limit:Transmission Opportunity is an interval of time when a WME AP has
the right to initiate transmissions onto the wireless medium (WM). This value
specifies (in milliseconds) the Transmission Opportunity (TXOP) for AP; that is, the
interval of time when the WMM AP has the right to initiate transmissions on the
wireless network.。

ACM bit:Admission Control Mandatory, ACM only takes effect on AC_VI and
AC_VO. When you do not click Checkbox, it means that the ACM is controlled by the
connecting AP. If you click Checkbox, it means that the Client is in charge。

No ACK policy bit:Acknowledgment Policy, WMM defines two ACK policies:
Normal ACK and No ACK. Click “Checkbox” indicates “No ACK”
When the no acknowledgement (No ACK) policy is used, the recipient does not
acknowledge received packets during wireless packet exchange. This policy is
suitable in the environment where communication quality is fine and interference is
weak. While the No ACK policy helps improve transmission efficiency, it can cause
increased packet loss when communication quality deteriorates. This is because
when this policy is used, a sender does not retransmit packets that have not been
received by the recipient. When the Normal ACK policy is used, the recipient
acknowledges each received uncast packet.。

When you create rules in the IP Filter List, the prior rules maintain higher priority. To allow limited
access from a subnet to a destination network manager needs to create allow rules first and
followed by deny rules. So, if you just want one IP address to access the system via telnet from
your subnet, not others, the Example 1 demonstrates it, not rules in the Example 2.
Example 1 :
Create a higher priority rule to allow IP address 192.168.2.2 Telnet access from LAN port first, and
deny Telnet access from remaining IP addresses in the same subnet.


While creating multiple Virtual Server rules, the prior rules have higher priority. The Virtual server
rules have precedence over the DMZ one while both rules exist. Example 1 and 2 demonstrate
proper usage of DMZ and Virtual Server rules.
Example 1 :
All connections should be redirected to 192.168.2.12 while DMZ is enabled. Since Virtual Server
rules have precedence over the DMZ rule all connections to TCP port 22 will be directed to TCP
port 22 of 192.168.2.10 and remaining connections to port TCP 20~80 will be redirected to port
TCP 20~80 of 192.168.2.11

7.6 QoS
Quality of Service (QoS) refers to both a network's ability to deliver data with minimum delay,
and the networking methods used to control the use of bandwidth. Without QoS, all traffic data is
equally likely to be dropped when the network is congested. This can cause a reduction in network
performance and make the network inadequate for time-critical application such as
video-on-demand.
A classifier groups traffic into data flows according to specific criteria such as the source address,
destination address, source port number, destination port number or incoming port number. For
example, you can configure a classifier to select traffic from the same protocol port (such as FTP)
to form a flow.


Route Information :
Select “Route Information” on the drop-down list to display route
table. PS-200N-AX could be used as a L2 or L3 device. It doesn’t support dynamic routing
protocols such as RIP or OSPF. Static routes to specific hosts, networks or default gateway
are set up automatically according to the IP configuration of system's interfaces. When used
as a L2 device, it could switch packets and, as L3 device, it’s capable of being a gateway to
route packets inward and outward.

ARP Table Information : Select “ARP Table Information” on the drop-down list to display
ARP table.
ARP associates each IP address to a unique hardware address (MAC) of a device. It is
important to have a unique IP address as final destination to switch packets to.


Bridge table information : Select “Bridge Table information” on the drop-down list to display
bridge table.
Bridge table will show Bridge ID and STP's Status on the each Ethernet bridge and its
attached interfaces, the Bridge Port should be attached to some interfaces (e.g. eth2,
ra0~ra7 and wds0~wds3).

Bridge MACs Information : Select “Bridge MACs Information” on the drop-down list to
display MAC table.
This table displays local MAC addresses associated with wired or wireless interfaces, but
also remember non-local MAC addresses learned from wired or wireless interfaces.
Ageing timers will be reset when existing MAC addresses in table are learned again or added
when new MAC addresses are seen from wired or wireless interfaces as well. When time
runs out for a particular entry, it will be pruned from the table. In that situation, switching
packet to that particular MAC address will be dropped.

Bridge STP Information : Select “Bridge STP Information” on the drop-down list to display a
list of bridge STP information.
