For WLANs to be able to reliably support mission-critical, high-throughput, or time-sensitive applications, RF interference must be continuously monitored. The WLAN must automatically and dynamically adapt to mitigate the effects of any interference in the environment. WLAN infrastructure has to provide the administrators with real-time, historical, and proactive visibility into the air to diagnose and mitigate interference. In this application note we will look at some of the tools that Aruba offers as a part of its WLAN solution that enable administrators to ensure reliable, high performing RF.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

4. IDENTIFYING AP AND USER HEALTH
An insight into the areas to analyze, when a given WLAN is
experiencing AP or User related performance issues.
5. 5
What is User Health?
Major Focus Areas:
1 ClientSignal Strength
2 ClientThroughput
Signal:
Green – 20dB
Orange – 15 – 20 dB
Red – <15 dB
Speed:
Green – >50% of Max
Orange – 25% – 50% of Max
Red – <25% of Max
6. 6
What are the key factors for quick overview?
RF Trends:
This reading is available on IAP on a
per clientbasis. For WMM deployments,
Signal (dB):
<15 Poor
15 – 25 Acceptable
>25 Good
Frames per sec:
Tx/Rx Retries are the prime factors to
be observed here.
Acceptable values differ according to
type of deploymentand traffic.
7. 7
What are the key factors for quick overview?
Speed and Throughput:
Clientbandwidth and throughputare directly related
entities.
While fluctuations are acceptable for DATA-ONLY
WLAN’s,
Deployments which focuses on VoWLAN require a
consistentand cleaner environment
Latency sensitive environments such as Warehouses
(Read:Barcode scanners) and Health care facilities
(Patient monitoring systems) require low retry, low
interference,low bit error error rate and sometimes
high throughputwireless network.
We can use this data as a dip-stick to optimize the
clientperformance
8. 8
How do I determine if an AP is healthy?
Utilization: %
Green - <50%
Orange – 50-75%
Red - >75%
Noise Floor: dBm
Green - >87 dBm
Orange – 80 dBm – 87 dBm
Red - <80 dBm
Error rate:fps
Green - <5000 fps
Orange – 5000 – 10000 fps
Red - >10000 fps

Prerequisites for working on client connectivity
Ensure to have the following information made available to you by the End-User or Customer,
Before beginning to work on client connectivity issues.
• Nature of the problem – Frequent disconnection, Unable to associate, Does not work in specific area,
Low speed, etc
• Magnitude of the issue reported – How many clients are affected, Partial or complete outage
• Client specific information – Mac or IP address, Client device type, OS and driver version, SSID to
which client connects
• Replicable – Is the issue replicable consistently or occurs on a random basis
• Deployment History – Was the issue present since deployment? Did the customer do a code upgrade
or config change?
14. 14
Useful support commands to isolate the cause
Command:show log user Purpose:Useful to identify user association pattern and potential causes for disconnection
15. 15
Useful support commands to isolate the cause
Command:show ap association Purpose:Verify if the user is indeed associating to the intended access point/radio band or not
16. 16
Useful support commands to isolate the cause
Command:show network
Purpose:If a specific clientis experiencing coverage issues,would itbe possible thatthe AP is
frequently dropping outof the cluster and overwrites with a different config,which causes it to not
broadcastthe intended ESSID to the end user?
Specifically applicable for customer environments with high congestion on wired network.
17. 17
Useful support commands to isolate the cause
Command:show ap bss-table Purpose:Used to identify is a specific radio band is broadcasting the required ESSID or not
18. 18
Useful support commands to isolate the cause
Command:show ap debug radio-stats 0
Purpose:If the customer is reporting that their users are noticing very low data transfer speeds despite having low number of
clients associated on a per AP basis,this command becomes quite useful.
It can be used to identify what is the fluctuation in channel busy percentage.NOTE: Radio ‘0’ denotes 5Ghz radio
19. 19
Useful support commands to isolate the cause
Command:show ap debug radio-stats 1
Purpose:If the customer is reporting that their users are noticing very low data transfer speeds despite having low number of
clients associated on a per AP basis,this command becomes quite useful.
It can be used to identify what is the fluctuation in channel busy percentage.NOTE: Radio ‘1’ denotes 2.4Ghz radio
20. 20
Useful support commands to isolate the cause
Command:show arm config
Purpose:To have a quick overview ofthe Adaptive radio managementconfiguration and determine the power setting
configuration when working on low clientsignal issues
21. 21
Useful support commands to isolate the cause
Command:show arm-channels Purpose:Channels enabled for ARM to move the AP’s to beacon on
22. 22
Useful support commands to isolate the cause
Command:show valid-channels
Purpose:Channels enabled for the
designated AP radio to scan the
immediate WLAN environment.
The data acquired through these scans
helps the VC to build a repository which
determines the best channel to which the
AP can move, in the event that the
existing channel becomes too congested
for optimal client performance.
NOTE: This is frequently confused with
ARM channels.It is vital to be able to
clearly differentiate between whatare
valid channels and ARM channels
23. 23
Useful support commands to isolate the cause
Command:show ap arm history
Purpose:If there is an excessive
interference in the WLAN network or if
there is a coverage hole in the network,
ARM has the ability to adjustthe AP’s
channel and power accordingly to
optimize performance.
In this example,we see that there are
numerous channel changes occurring
where the reason is mention as
I – denoting ‘Interference’
24. 24
Useful support commands to isolate the cause
Command:show ap arm neighbors
Purpose:The AP would be scanning the list of valid channels and during
this scan, it would be able to
detect the neighboring BSSID,
ESSID, Channel,SNR,tx-
power of discovered radio,
Path loss and the type of scan
via the discovery was made.
This information is useful
when working with customers
who have their IAP network
setup in a multitenant
environmentand to verify if
any of the neighboring BSS
are encroaching on a channel
allocated to the customer in
concern.
25. BEST PRACTICES
Default WLAN config is not suitable for all customer environments.
The following section gives a preview of how to right-size a given
WLAN depending on requirements and environmental conditions.
26. 26
Best Practices – Network RightSizing
What is meant by network Right-Sizing?
It is a proven fact that network rightsizing results in cutting network operation costs by 70%.
Converging from wired to wireless would be the first step but optimizing the WLAN environmentfor best performance is
absolute key for your customers to achieve this result.
You can refer the following data for in-depth details,
http://www.arubanetworks.com/pdf/technology/whitepapers/wp_Rightsizing.pdf
http://www.arubanetworks.com/assets/so/SB_Rightsizing.pdf
Optimizing a poorly performing WLAN may result in customers requiring fewer data ports to be active,Also the connected
devices can utilize the VHT data rates along with mobility, which results in an extremely agile as well as high performing
access network for your customers.
The primary bottleneck is during the post-deploymentphase,where the deployed network under-performs.
Let us have a quick overview on how to help customers optimize this and take advantage oftheir HPE-Aruba WLAN.
27. 27
Adaptive Radio Management Config – AP Tx Power
Adjust the AP’s transmit power to suit the customer
environment.
More Tx power does not always mean that the AP
is performing at its best.
While this could mean that the AP is going to have
a larger coverage cell,
If the Min Tx power of the AP is forced to a higher
value,it is very much likely to cause
Interference for a valid neighbor AP in the cluster,
Especially in the 2.4Ghz radio as the channels get
re-used more frequently compared to 5Ghz
28. 28
Adaptive Radio Management Config – AP Tx Power
How do I quickly determine what would be a suitable Tx power range for a customer?
They cannot budget a site survey just for this purpose.
The customer does not have to run a WLAN network analysis to determine this.
Observe the Tx EIRP of the AP’s in the cluster, if the Min Tx is set to 18 and most of the
AP’s
are reporting their Tx EIRP as ‘18’, then the next step would be to check whether we
have ARM doing excessive channel changes with the reason being “I - Interference”.
LOGIC:
As the Min Tx has already been capped at a high value, the AP is trying to shrink its cell
size.
However, it cannot push lower than 18, hence it keeps bouncing between multiple
channels.
29. 29
Adaptive Radio Management Config – AP Tx Power
What is the next course of action if we see that AP’s are either stuck at Min Tx
Or Max Tx EIRP?
While its permissible for AP’s to use Min and Max Tx power levels, a network wide
usage of this signifies room for improvement.
Min Tx – Excessive coverage
Max Tx – Potential coverage hole
If AP’s are stuck in Min Tx, try and reduce the ARM Min Tx value by 3 dBm until the AP stops reporting interference
If the AP is stuck in Max Tx, Check whether there are any AP coverage holes and the specific AP may need to be
moved/oriented,else the area mightrequire an additional access point.
30. 30
Band Steering – Prefer 5Ghz
Ensure customer network uses band steering whenever permissible.
Default configuration is as below and may not be applicable for all customers.
There are three modes for Band steering with the
defaultbeing – Prefer 5Ghz. If the conditions below
are met, the AP will not respond to 2.4Ghz probe from
the client.
• The client has already probed the AP on the 5Ghz band
and therefore is known to be capable of sending probes
on the 5Ghz band.
• The client is not currently associated on the 2.4Ghz
radio to this AP.
• The client has sent less than 8 probes requests/authin
the last 10 seconds. If the client has sent more than 8
probes in the last 10 seconds, the client will be able to
connect using whatever band it prefers
31. 31
Band Steering – Force 5Ghz
Ensure customer network uses band steering whenever permissible.
Default configuration is as below and may not be applicable for all customers.
Force 5Ghz is applicable in cases where we have an
already very crowded 2.4Ghz spectrum and
additionally,the available 5Ghz clients are exhibiting
sticky client behavior are notpreferring to join 5Ghz
radio.
AP will stop responding to client’s 2.4Ghz probe, if
• The client has already probed the AP on the 5Ghz band
and therefore is known to be capable of sending probes
on the 5Ghz band.
• The client is not currently associated on the 2.4Ghz
radio of this AP.
32. 32
Band Steering – Band Balance
Ensure customer network uses band steering whenever permissible.
Default configuration is as below and may not be applicable for all customers.
In this band steering mode, the AP uses clientload
and RSSI information to balance the clients across the
two radios and best utilize the available 2.4G
bandwidth.
This feature takes into account the fact that the 5Ghz
band has more channels than the 2.4 Ghz band, and
that the 5Ghz channels operate in 40MHz while the
2.4Ghz band operates in 20MHz.
Due to the higher bandwidth availability in 5Ghz,it is
always preferred to have a higher ratio of 5Ghz band
based clientassociation.
33. 33
Efficient Channel Management System
Customizing valid channels available for the AP to
operate is a key factor in improving WLAN
performance.
Customer network mightneed this for following
reasons,
• Presence of a known Rogue AP in a specific
channel
• Heavy Utilization of a specific channel by
neighboring/multitenantWLAN
• 3rd
party stand alone WLAN video/security
cameras operating in a certain channel
34. 34
Efficient Channel Management System
In this example,
We are removing channel – 11
From being a part of the valid channel list.
With the scenario where – Channel 11 is considered
as a known LOW PERFORMING channel.
By removing it from ARM channel as well as valid
channel list,AP’s performance can be improved.
35. 35
Enable Client Match
ClientMatch is importantas it integrates multiple
Features into a unified stream.
On clicking an access pointin the Access Points
tab and the ClientMatch link,a stations map
view is
displayed and a graph is drawn with real-time
data points for the AP radio.If the AP supports
dual band,you
can toggle between 2.4GHz and 5 GHz links in
the clientmatch graph area to view the data.
When you hover
the mouse on the graph,details such as RSSI,
clientmatch status, and the client distribution on
channels are displayed.
37. 37
Use Airtime Fairness feature Effectively
The airtime fairness feature provides equal access to all
clients on the wireless medium, regardless of client
type, capability, or operating system, thus delivering
uniform performance to all clients.
This feature prevents the clients from monopolizing AP’s
radio resources.
Default Access – This option will provide access based on
client requests. When Air Time Fairness is set to default
access, per user and per SSID bandwidth limits are
not enforced.
Fair Access – This option will allocate Airtime evenly across
all the clients.
Preferred Access - Select this option to set a preference
where 11n clients are assigned more
airtime than 11a/11g. The 11a/11g clients get more
airtime than 11b. The ratio is 16:4:1
