Top 10 Cisco Wireless “Good to Know”
1) Controller interface vlan tagging, native vlan 1
Cisco Switches by default do not tag the native vlan. Also by default, the native vlan is 1, therefore vlan 1 is untagged.
When establishing a trunk to a Cisco Wireless LAN Controller, it's important to be aware of how tagged vs untagged are identified.
(4400-A) >show interface summary
Interface Name Port Vlan Id IP Address Type Ap Mgr Guest
--------------- ---- ---------- -------------- ----- ------ -----
ap-manager 1 untagged 18.104.22.168 Static Yes No
management 1 untagged 22.214.171.124 Static No No
When going through a WLC's initial startup wizard, if untagged for the Management Interface’s vlan is desired, enter '0' (zero) when prompted for the management interface's vlan, as this is equivalent to 'untagged':
Welcome to the Cisco Wizard Configuration Tool
Use the '-' character to backup
Would you like to terminate autoinstall? [yes]:
Management Interface VLAN Identifier (0 = untagged): 0
2) AP Image Names: w7 vs w8
ap image names:
w7 = standalone
w8 = lightweight
Lightweight/controller based/capwap/lwapp image:
Cisco IOS Software, C1130 Software (C1130-K9W8-M), Version 12.4(23c)JZ, RELEASE SOFTWARE (fc1) c1130-k9w8-mx.124-23c.JZ
Cisco IOS Software, C1140 Software (C1140-K9W7-M), Version 12.4(21a)JY, RELEASE SOFTWARE (fc1)c1140-k9w7-mx.124-21a.JY
3) AP Part Numbers: LAP vs AP
Most Cisco Access Points are available with two part numbers.
LAPxxx = shipped new from manufacturing with lightweight image
APxxx = shipped new from manufacturing with autonomous image
Same physical hardware.
Same physical ap's, the first is shipped with a lightweight image, the second with an IOS image:
Most AP's can be converted between both modes.
4) Wireless LAN Controller DHCP Handling
Wireless Lan Controllers perform 'dhcp proxy' by default. The ‘Dhcp Server’ IP Address configured on controller interfaces acts the same way as an 'ip helper' statement on a Cisco router.
With this configuration in place, an IP Helper statement on the wireless clients’ default gateway router is not necessary.
DHCP Proxy can be configured via the WLC’s GUI in 6.x and 7.x code (Controller -> Advanced -> DHCP).
Earlier code requires CLI access for configuration:
(WLC) >show dhcp proxy
DHCP Proxy Behaviour: enabled
(WLC) >config dhcp proxy disable
(WLC) >show dhcp proxy
DHCP Proxy Behaviour: disabled
5) Lightweight AP modes: Local vs H-Reap (FlexConnect)
Local mode Access Point: tunnels all traffic to controller, controller responsible for tagging packets and putting them on the wired network, AP's switchport configured in access mode/non trunk.
H-Reap mode Access Point: ap's function similarly to standalone ap's, tag their own traffic, AP's switchport configured as trunk. Vlan tagging requires configuration on each H-Reap mode AP (Via the controller’s Gui).
*H-Reap was renamed to 'FlexConnect' in 7.2 code.
6) Legacy Access Points End of Support
1500 Series, LAP-1505, LAP-1510: Last supported in 4.2.M controller code.
1000 Series, AP1010, AP1020, AP1030: Last supported in 4.2 controller code.
1120/1230 Series, 1121, 1230, etc. Last supported in 7.0 code.
1130, 1240, 1520. Last supported in 8.0 code (no support in 8.1 and later).
Software Release Support for Access Points
These Access Points will not join a controller running code later than supported.
7) AP console settings
•8 data bits
•1 stop bit
*********No hardware flow control******
These are the same settings for other Cisco devices. It is essential that AP's console session have flow control disabled. Most other Cisco devices will tolerate this setting if not disabled, but AP's will not. The result is typically no display and/or keyboard response.
8) WLC Dynamic Interfaces, Does it Route?
Those familiar with Cisco routing and switching may get the impression that Wireless Lan Controllers have routing capability. This may seem apparent due to the fact that multiple dynamic interfaces with ip addresses may be configured. WLC's do not route.
The ip addresses assigned to the dynamic interfaces are not used for client traffic passing through the controller.
Dynamic interfaces' IP addresses primary functions are:
+ Referenced as Giaddr for DHCP Proxy (relay)
+ Multicast. For wireless multicast receivers connected to local mode ap's, if the controller has IGMP snooping enabled, it will proxy/spoof IGMP reports to the wired network using the client's corresponding dynamic interface IP address. If IGMP snooping on the controller is disabled, client IGMP reports are forwarded unmodified to the wired network.
+The IP address is checked when you do an intercontroller roam, so that the WLC knows if you did a L2 or L3 roam, and whether to anchor your traffic or to pass the MSCB entry to the new WLC.
By default, multicast traffic is not forwarded by Wireless Lan Controllers for local mode ap's.
A common source of confusion is that Autonomous Mode AP's will forward multicast just as they would unicast, so no configuration is required. In the instance of Autonomous AP's being converted to Controller Based/Lightweight, multicast will no longer work until configured on the controller.
Since Controller based H-Reap mode ap's forward their own traffic, multicast will behave as if the AP were a standalone AP, and no controller configuration is required.
10) Anchored Wlans. Where does authentication occur?
For Layer 3 authentication, e.g. Web Auth, authentication handling occurs on the Anchor Controller.
For Layer 2 authentication, e.g. 802.1x, authentication handling occurs on the Foreign controller.
A: Regarding point 8 about the dynamic interfaces configured on the WLC, it is perhaps worth adding that they can act as source addresses when clients try to obtain an ip address via DHCP. This document explains more: http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a00805e7a24.shtml
B: You may want to add what else the dynamic-interface IP comes to play for. The IP address is checked when you do an intercontroller roam, so that the WLC knows if you did a L2 or L3 roam, and whether to anchor your traffic or to pass the MSCB entry to the new WLC.
C: A note on the AP support - I believe that some APs will join WLCs with code 8.1 but new features won't be supported such as AVC on local FlexConnect due to hardware limitations.
Note The Cisco 1040 Series, 1140 Series, and 1260 Series access points have feature parity with Cisco Wireless Release 8.0. Features introduced in Cisco Wireless Release 8.1 and later are not supported on these access points.

Cisco HDX Manages Performance on Crowded Wi-Fi Networks Wi-Fi traffic is everywhere.
More users-employees, customers, and guests alike - are connecting to the network. Most of these users carry multiple Wi-Fi devices and many devices support only wireless connectivity. All this leads to lots of very dense Wi-Fi traffic in the air.
And with the introduction of 802.11ac Wave 2 technology, networks are only going to get more crowded. That’s why Cisco has enhanced its High Density Experience (HDX) suite of solutions, which automatically manages the airwaves and improves Wi-Fi performance.
Now, available on Cisco’s Indoor Access Points the Cisco Aironet 3800 and 2800 Series and the Cisco’s Outdoor Access Points the Cisco Aironet 1570 and 1560 Series Outdoor Access Point,
HDX is regularly updated with new features that alleviate high-density network strain and improve user experiences as 802.11ac and other trends load the airwaves with more traffic.
Managing Your Airwaves
• Alleviate network strain when large volumes of client devices contend for access point connectivity
• Improve Wi-Fi throughput and spectrum efficiency
• Prevent unnecessary Wi-Fi disconnections
• Enable access points to quickly change channels to mitigate interference or narrow bandwidth instead of abandoning the entire channel
• Allocate air time to specific user groups
Simplifying and Automating RF Tasks Below are some of the more recent HDX feature enhancements:
• Enhanced Optimized Roaming: If performance degrades as Wi-Fi users move, this feature intelligently steers clients to an access point with a stronger signal - without interrupting the connection.
• CleanAir for 160-MHz Channels: Proactive protection against RF interference with spectrum scanning, source identification, and remediation that now works across 160-MHz channel widths.
• ClientLink: Cisco’s patented beamforming technology that improves performance of 802.11ac clients as well as 802.11a/g/n legacy clients.
• Dynamic Bandwidth Selection (with FlexDFS): Continually analyzes and selects the best channel width for use in current conditions. If radar is detected on part, but not all, of the frequency, the access point can narrow the serving channel from 160 to 80 to 40 or 20 MHz, rather than moving entirely to a new frequency, enhancing spectrum efficiency.
• Event-Driven Radio Resource Management (ED-RRM): Rapidly changes channels to avoid interference, doing in seconds what previously could take minutes. IT can also set thresholds to determine when traffic automatically moves to a clear or less busy channel.
• HDX Air Time Fairness (ATF): Simplifies Wi-Fi traffic management by enabling network administrators to allocate specific percentages of airtime to heterogeneous groups of clients or customers.
More about the Cisco HDX Solution
HDX is a broad and comprehensive suite of solutions delivered in the Cisco Aironet 2700 and 3700 Series access points, consisting of both hardware and custom application-specific integrated circuits (ASICs) and software elements to provide optimal performance in high-density WLAN environments.
Cisco developed HDX to address the increasing proliferation of both wireless networks and wireless devices (such as smartphones, tablets, and PCs) carried by individual users - creating increased traffic. HDX directly addresses the expectations of both network administrators and mobile device users that WLANs will continue
to “just work” despite increasingly demanding scenarios.
In brief, when designing HDX, Cisco carefully considered the ramifications of increases in:
● Access point density (public and residential)
● Co-channel and adjacent channel interference
● Inter-access point contention
● Intra-access point contention (due to more clients and increased upstream)
● Client density
● Variation in client types
Therefore, HDX is essential for WLANs operating in environments that are characterized by any of the following:
● Many clients connected to a single access point
● Many colocated access points deployed as a single WLAN with partial to full channel (frequency) overlap
● Many independent yet neighboring WLANs needing to coexist in the same spectrum
● Increased loading due to more upstream and downstream video traffic: more FaceTime and Skype traffic (bidirectional interactive apps, unified communications), more mobile app downloads, more uploading of personal content (photos, cloud/sync functions, etc.)
HDX Features Provided in the Cisco Aironet 2700 and 3700 Series
The primary features of HDX are:
● Cisco CleanAir 80 MHz
● Cisco ClientLink 3.0
● Optimized Roaming enhanced with BSS Transition Management
● Turbo performance
● Enhancement: Dynamic Bandwidth Selection (with Flexible Dynamic Frequency Selection (FlexDFS))
● Enhancement: Wi-Fi triggered Event-Driven Radio Resource Management (ED-RRM)
● Enhancement: Air Time Fairness
● RF noise reduction (available in future versions)
Each of these features is detailed in the sections that follow.
Cisco is the only equipment vendor to have the complete suite of features that make up HDX. Furthermore, it is the only equipment vendor to have a purpose-built access point with hardware acceleration that supports HDX and that is designed specifically for the high-performance challenges of 802.11ac.

Use Spare Router Cycles to Host Linux VMs
In this summer, Cisco introduced a capability that we quietly rolled out in a software release last November (IOS XE 3.17). You can now host your own custom or third party KVM lightweight applications directly on your ISR 4000 or ASR 1000.
Kernel-based Virtual Machines, the KVM, are the standard virtualization technology in the embedded Linux world. If you’re writing applications to be hosted across a network, odds are you’re already using it. The ability to virtualize across the network is a key aspect of Cisco DNA so this capability dovetails very nicely with the larger solution for enterprise environments.
Get the Most from Your Branch Router
Many lightweight applications and network functions needed in a modern network or branch office are available as virtual machines (VM). If you need to host some of these functions in the network, use your Cisco router to do it instead of deploying a dedicated appliance at your branch site.
You’ll reduce complexity and cost by making use of spare compute horsepower that’s already in your router. Very efficient.
Run the Apps You Need...
Use the Cisco 4000 Series Integrated Services Router (ISR) and ASR 1000 Series Aggregation Services Router to host not only Cisco apps, but also third-party and homegrown Linux-based apps. These routers’ Cisco IOS XE operating system supports the Kernel-based Virtual Machine (KVM), a virtualization infrastructure for the Linux kernel that turns it into a hypervisor.
Both routers use a customized high-performance data plane for forwarding and manipulating packets. The control plane is entirely Linux running on an x86 Intel CPU. We designed the routers with extra CPU capacity for hosting VMs.
You can also turn to the Cisco 4000 Series ISR and ASR 1000 Series to host other network functions that can be deployed as VMs, including:
• Windows domain controller
• Print servers
• Network analytics
• Network functions such as WAN optimization (Cisco WAAS), intrusion detection and prevention (Snort IPS), and visibility and security intelligence (Cisco Stealthwatch Learning Network License)
Hosting those VMs directly on your existing physical router makes a whole lot of sense.
...With the Performance You Expect
VMs are not hosted in the data plane of the router, so there is no performance impact on packet forwarding or feature processing. Critical control plane functions run at a higher priority than hosted VMs.
This is industry-standard Linux virtualization at its finest.

You can relax when you have Cisco Aironet 3800 Series Access Points deployed and running.
Why? Cisco Aironet 3800 Series Access Points and Cisco Aironet 2800 Series Access Points support 802.11ac Wave 2, increasing bandwidth for more devices. Cisco goes beyond the industry standard to provide advanced innovation that self-optimizes your network in unpredicted times of high density, with a feature called Cisco Flexible Radio Assignment.
In addition to the device deluge, there are times when a lot of people moving in and out of your network can complicate a high-density network environment. A manual approach to recalibrating your wireless network every time there is an unexpected usage change isn’t practical. Flexible Radio Assignment automatically adapts to these temporary high-density environment changes.
Flexible Radio Assignment is a Cisco innovation designed to provide a better mobile user experience for high-density networks by automatically detecting when a large number of devices are connected to a network. Once the detection is made, Flexible Radio Assignment changes its dual radios in the access point from 2.4 GHz/5 GHz to 5 GHz/5 GHz to serve more clients. The access point performs this function while still monitoring the network for security threats and RF interference that may affect performance.
Flexible Radio Assignment has three different modes of operation:
• Default operating mode, which serves clients on both 2.4 GHz and 5 GHz
• Dual 5-GHz mode, which serves clients on both 5-GHz radios
• Wireless security monitoring, which scans both 2.4 GHz and 5 GHz for security threats while also serving 5-GHz clients
How do these features work in an everyday setting?
The best way to describe this feature is by returning to the original scenario of a large number of office workers expecting to hear a speech from the boss.
As the first group of workers trickles into the conference room, the Cisco Aironet 3800 Series Access Points automatically determine that there is ample 2.4-GHz and 5-GHz wireless coverage. During the minutes before the meeting, these access points use the wireless security-monitoring mode in the 2.4-GHz radio to continually scan both bands for RF interference or security threats. Cisco CleanAir Technology eliminates any detected interference while rogue detection and containment and wireless intrusion prevention systems (wIPS) rectify security threats.
As the meeting looms closer and the high-density scenario is realized, Flexible Radio Assignment adapts in real time, and the Cisco access point radios provide the precise amount of 2.4-GHz and 5-GHz coverage. Some access points will convert both radios to the 5-GHz band to serve the additional clients and provide better coverage and performance during the high-density event.
This availability of the larger band is extremely helpful, as a majority of the audience is following the video feed of the conference over their wireless devices too.
Following the meeting, the access points return to default operating mode, offering 2.4-GHz/5-GHz coverage while other access points transition to wireless security monitoring mode.
The most amazing thing about this scenario is that, as the network administrator, you didn’t have to do anything to facilitate the extra bandwidth. The Cisco Aironet access point is intelligent enough to do the entire thing itself. This allows you to concentrate on more pressing issues.
Flexible Radio Assignment isn’t strictly for workplace environments.
It can be used in nearly any instance where a large group of people gather. Whether it’s in an educational setting, a hotel lobby, or a hospital, Flexible Radio Assignment is a boon to any wireless network.
From bring your own device (BYOD) to Internet-of-Things (IoT) devices, the proliferation of wireless items brings a new host of challenges as bandwidth-intense applications grow. Flexible Radio Assignment rises to these challenges and augments your wireless network to do more without making your job difficult.
Now if only the Flexible Radio Assignment could give Bob from accounting some new jokes.

Everyone says I love 802.11ac Wave 2. The Impact of 802.11ac Wave 2 is World Wide, Why? We also talked about the 802.11ac Wave 2 and 802.11ac Wave 2 Access Points a lot.
Yes, make no mistake the affect of the 802.11ac Wave 2 standard is going to be global and won’t just affect specific business areas.
One key part of Wave 2 802.11ac technology that helps keep your organization ahead of the capacity crunch is multi-user MIMO (MU-MIMO).
(MU-MIMO allows an access point to transmit to multiple clients at the same time, instead of sending data to a single client at a time. These parallel transmissions improve RF efficiency when client devices also support 802.11ac Wave 2.)
With Muti-User MIMO (MU-MIMO), 802.11ac Wave 2 clients are on and off the network so fast allowing for more legacy clients to be served. Plus 802.11ac Wave 2-enabled smart phones, laptops and tablets, will jump on the 5Ghz band leaving the 2.4GHz bands for older devices.
With the higher speeds of 802.11ac Wave 2, it takes a lot less time to transmit data than it did with previous Wi-Fi standards. This preserves battery life on Wave 2 clients. That means in the long run, updating your wireless network to 802.11ac Wave 2 standards will provide a better user experience for your users.
Now, let’s look at why 802.11ac Wave 2’s Impact is World Wide.
Schools need to support 802.11ac Wave 2 because more and more students are bringing devices to class. And it’s not to sneak a peek at the latest Taylor Swift video; educators are using tablets and other mobile devices as part of the education process. While additional devices and apps that will consume bandwidth are a big reason for the upgrade, it’s not the only thing. Schools need an 802.11ac Wave 2 network that can:
• Support up-to-the minute notification on mobile devices.
• Detect externally launched attacks and insider threats.
• Automatically adapts to environment changes for optimal performance.
Whether you’re a small coffee shop or a large department store, it’s not just your workers that need exemplary Wi-Fi, customers demand this service too. Cisco Aironet Access Points are great tools to gather data in order to understand customer traffic patterns and behaviors, prioritizing your business-driving apps and better protecting the privacy of your business. Your customers need to be able to jump on a network too and:
• Connect to a custom guest access network (which can be used as another advertising venue).
• Be able to find the things that they want, quicker.
• Adapt to flash crowds during sales events.
In the old days, putting out an array of stale donuts in the morning and offering travelers a bed for the night was the peak of hospitality luxury. Those days are long gone as guests are now a bit savvier than they once were and expect a multitude of high-end services. One of these services is a robust wireless network. If you’re in the hospitality game, you need an 802.11ac Wave 2 compliant network because:
• It delivers mobile check-in, key lock and room control
• It quickly deploys wireless access for conventions and social gatherings
• It adapts to crowd surges during high volume of registration
Where Does Cisco Fit In?
That third bullet brings me to one of the most amazing things about the Cisco Aironet Access Points, and that are the innovations that only Cisco delivers:
• Flexible Radio Assignment automatically adjusts radio bands to better serve the environment. A Cisco Aironet Access Point deployed in a hotel lobby can handle a crowd of people armed with mobile devices frantically looking to get settled in their rooms. Flexible Radio Assignment automatically triggers the access point to shift from the dual radios operation at 2.4GHz and 5GHz to both radios offering 5GHz.
• Cisco CleanAir remediates device impacting interference
• Optimized Roaming intelligently connects the proper access point as people move
• Multi-Gigabit Uplinks provides faster wired network offload on existing Ethernet
Your Cisco 802.11ac Wave 2 access points aren’t static. They offer investment protection via the ability to expand along with your organization with three ports located on the Cisco Access Point. A smart antenna port allows you to add either another antenna be it of the Stadium Panel, Directional or Location variety. A built-in module port is perfect for connecting hardware such as a video surveillance device. While a USB port allows you to add a Bluetooth capabiities.
Preparing for 802.11ac Wave 2 is not a one-sized-fits-all solution. Cisco has a wide access point portfolio that offers different solutions to fit different situations. The Cisco Aironet 1830 and 1850 Series Access Points are perfect fits for small to medium-sized businesses. These devices offer the functions and features of an enterprise-level access point and they are the lowest cost 802.11ac Wave 2 AP on the market today.
For mission-critical organizations, look no further that Cisco Aironet 2800 Series Access Point. More robust than the Cisco Aironet 1830 and 1850 Access Points, the 2800 Series is built for large sized organizations. Rounding out the portfolio is the Best-in-Class solution: the Cisco Aironet 3800 Access Point. This product is targeted specifically for larger areas such as stadiums and arenas.
What’s new? The network is an informational highway of intelligence, but today’s static infrastructure can’t see the intelligence. The first step in addressing this issue is increasing visibility into the network with insights and analytics. Next is automating network services to make it easy to deploy, manage and maintain.
Cisco’s new network innovations address both challenges, and include:
Insights and Experiences:
- Cisco Connected Mobile Experience (CMX) 10.2.2 – a software update with new features and enhancements for better customer engagement, operations and streamlined guest experiences
- Cisco Aironet 1560 Series Outdoor Access Point – Cisco’s first outdoor Access Point that extends 802.11ac Wave 2 Wi-Fi to high-density environments, the foundation to enable CMX for your outdoor environments.
- Cisco Catalyst 3650 Multigigabit Switch – a new Catalyst Multigigabit technology (based on NBASE-T standards) switch with up to 48 ports (12 MGig) and UPOE up to 60w for voice, video, and data performance assurance
Automation and Assurance:
- ASR 1001-HX and ASR 1002-HX– new fixed –HX chassis that offer WAN edge high availability and resiliency with Service Level Agreement (SLA) assurance in a small form factor.
- Cisco Unified Compute Services (UCS) E-Series – new 6-core single-wide compute blade for ISR 4000 with enhanced processing, memory and storage for 2x more app hosting.
- 3rd Party App Hosting on ISR 4000 & ASR 1000 – Cisco now supports KVM-based application hosted as container on Cisco Enterprise Routers, providing more choices and openness support for 3rd party or custom application.
What are the challenges Cisco is helping you overcome?
The roadmap to a digital network may seem simple, but there are significant challenges that must be overcome. With these new network innovations customers can tackle:
- WAN Edge Challenges–The WAN is the fabric that connects users to apps and things. It also is the central point between the enterprise core and its edges—from the core to campus/HQ, branches, cloud and fog or among enterprise private data centers. The WAN edge must balance between performance, visibility, and security to ensure the best user experience (i.e. quality of voice, video, and data).
- Branch Challenges–The branch is the first node of connection for users and guests to apps and things, as well as the first line of defense to nullify a threat. Given its small IT footprint and often remote locations, the branch challenges include application experience, connectivity, management and automation, threat detection and defense.
- Customer Experience Challenges–To deliver a personalized customer experience, two integral steps must happen in tandem: (i) ubiquitous and robust connection, indoors and outdoors, and (ii) user, app, and device intelligence.
How will the new innovations help customers?
This is always a question we ask ourselves when rolling out any new technology. Focusing on real business outcomes for your enterprise, Cisco and our DNA approach is built on three design principles.
- Services-centric to give enterprises the freedom to run services and applications when, where, and how they want it across the WAN and branch. Outcome: Faster service delivery.
- Software-driven by virtualizing and optimizing applications and network functions for effective deployment on any platform: physic, virtual, or a mix of both. Outcome: Freedom of choice.
- Automation of devices, apps and services for greater agility. Outcome: Less human errors.
Cisco DNA is the future of the network. These innovations allow you to reach greater network agility and achieve real business outcomes.
