Deploying Cisco ASA FirePOWER Services in the Data Center

January 3 2017 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall, #Networking, #Cisco & Cisco Network, #Cisco Technology - IT News

The Data Center is a one of popular words in network communication. And it can be definited as a very complex world.

The Data Center not only provides a rich set of services and architectures but also hosts the crown jewels of an organization. It is extremely important to maintain visibility of everything that is happening in the data center.

The concept of “north-to-south” and “east-to-west” is often used in describing the types of communication (or flow) within and to the outside of the data center:

  • North-to-south describes communication between end users and external entities.
  • East-to-west describes communication between entities in the data center.

The following Figure illustrates the concepts of north-to-south and east-to-west communication.

 

The data center has many different high-throughput and low-latency requirements, in addition to increased high-availability requirements. In addition, automated provisioning and control with orchestration, monitoring, and management tools are crucial.

The data center architecture consists of three primary modular layers with hierarchical interdependencies:

  • Data center foundation: This is the primary building block of the data center, on which all other services rely. Regardless of the size of the data center, the foundation must be resilient, scalable, and flexible to support data center services that add value, performance, and reliability. The data center foundation provides the computing necessary to support the applications that process information and the seamless transport between servers, storage, and the end users who access the applications.
  • Data center services: These services include infrastructure components to enhance the security of the applications and access to critical data. They also include virtual switching services to extend the network control in a seamless manner from the foundation network into the hypervisor systems on servers to increase control and reduce operational costs (as well as other application resilience services).
  • User services: These services include email, order processing, and file sharing or any other applications in the data center that rely on the data center foundation and services, like database applications, modeling, and transaction processing.

The Figure below illustrates some of the components of the data center services architecture.

 

Examples of the data center service insertion components include the following:

  • Firewalls (In the example illustrated in the Figure above, Cisco ASAs with FirePOWER modules are deployed.)
  • Intrusion prevention systems (IPS)
  • Application delivery features
  • Server load balancing
  • Network analysis tools (such as NetFlow)
  • Virtualized services deployed in a distributed manner along with virtual machines
  • Traffic direction with vPath and Nexus 1000v
  • Application Centric Infrastructure (ACI) automated framework components for service insertion

In the case of virtualized environments, the Cisco ASAv (virtual machine) can be deployed to protect VM-to-VM communication. The Cisco ASA FirePOWER module in these environments is not supported, as the Cisco ASAv is just a virtual machine. Cisco FirePOWER virtual machines running network AMP can be deployed in those scenarios.

NOTE: The Cisco ASAv supports both traditional tiered data center deployments and the fabric-based deployments of Cisco ACI environments. The Cisco ASAv can also be deployed in cloud environments like Amazon Web Services (AWS).

The Cisco ASA with FirePOWER modules can be deployed in geographically dispersed cluster environments.

The following Figure shows an example in which four Cisco ASAs with FirePOWER modules are deployed in two separate sites (site A and site B).

 

In the example illustrated in the Figure above, the cluster of four Cisco ASAs is fully extended between the two data centers, using the cluster control links (CCL) operating at Layer 2 with a latency of less than 10 milliseconds. A single spanned EtherChannel for transient data is used on the cluster side. The local data links are also configured with EtherChannels at the switch pairs on each site.

TIP: The data VLANs between the switches are not extended to prevent network loops.

December 20 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Networking, #Cisco & Cisco Network

You should hear of the Fat, Thin, and Fit APs. What are they?

The terms thin and fat have been applied to WLAN access points (APs) in many different ways.

  • Some vendors use thin AP to refer to entry-level/residential-grade products with few advanced features, in comparison to fat APs rich with enterprise network features like VLAN tagging and SNMP-based management.
  • Some use thin AP to refer to products that can't be configured or used on their own, but instead are part of a WLAN switching system that governs both setup and operation. In this case, a fat AP is any stand-alone AP, no matter how extensive that AP's feature set.
  • Some use thin AP to refer to products that offload selected tasks to an upstream server -- for example, communicating with 802.1X Authentication Servers, generating encryption keys, acting as a VPN gateway, or re-routing traffic for cross-network mobility. In comparison, any of these tasks could be performed directly on a fat AP, without relying on an upstream server.

In the autonomous architecture, the WTPs (Wireless Termination Point) completely implement and terminate the 802.11 function so that frames on the wired LAN are 802.3 frames. Each WTP can be independently managed as a separate network entity on the network. The access point in such a network is often called a Fat AP.

FAT APs in Autonomous WLAN Network Architecture

 

During the initial stages of WLAN deployment, most APs were autonomous APs, and manageable as independent entities in the network. During the past few years, centralized architectures (discussed next) with ACs and WTPs have gained popularity. The primary advantage of the centralized architecture is that it provides network administrators with a structured and hierarchical mode of control for multiple WTPs in the enterprise.

Centralized Architecture

The centralized architecture is a hierarchical architecture that involves a WLAN controller that is responsible for configuration, control, and management of several WTPs. The WLAN controller is also known as the Access Controller (AC). The 802.11 function is split between the WTP and the AC. Because the WTPs in this model have a reduced function as compared to the autonomous architecture, they are also known as Thin APs. Some of the functions on the APs are variable, as discussed in the following section.

Thin APs in Centralized WLAN Network Architecture

 

Distributed Architecture

In the distributed architecture, the various WTPs can form distributed networks with other WTPs through wired or wireless connections. A mesh network of WTPs is one example of such an architecture. The WTPs in the mesh can be linked with 802.11 links or wired 802.3 links. This architecture is often used in municipal networks and other deployments where an outdoor component is involved. This article does not address the distributed architecture.

WTP Functions Fat, Thin, and Fit APs

To understand the autonomous and centralized architecture, it is useful to look at the functions performed by the APs. We start with the Fat APs, which form the core of the autonomous architecture, followed by the Thin APs, which were specified as part of the WLAN switch- or controller-based centralized architecture. The article will then outline the functions of a new variant called the Fit AP, an optimized version of the AP for centralized architectures.

Fat Access Points

Figure1 shows an example of an autonomous network with a fat access point. The AP is an addressable node in the network with its own IP address on its interfaces. It can forward traffic between the wired and wireless interfaces. It can also have more than one wired interface and can forward traffic between the wired interfaces similar to a Layer 2 or Layer 3 switch. Connectivity to the wired enterprise can be through a Layer 2 or Layer 3 network.

It is important to understand that there is no backhauling of traffic from the Fat AP to another device through tunnels. This aspect is important and is addressed when discussing the other AP types. In addition, Fat APs can provide router-like functions such as the Dynamic Host Configuration Protocol (DHCP) server capabilities.

Management of the AP is done through a protocol such as the Simple Network Management Protocol (SNMP) or the Hypertext Transfer Protocol (HTTP) for Web-based management and a Command-Line Interface (CLI). To manage multiple APs, the network manager has to connect to each AP through one of these management schemes. Each AP shows up on the network map as a separate node. Any aggregation of the nodes for management and control has to be done at the Network Management System (NMS) level, which involves development of an NMS application.

Fat APs also have enhanced capabilities such as Access Control Lists (ACLs), which permit filtering of traffic for specific WLAN clients. Another significant capability of these devices is configuration and enforcement of Quality of Service (QoS)-related functions. For example, traffic from specific mobile stations might need to have a higher priority than others. Or, you might need to insert and enforce IEEE 802.1p priority or Differentiated Services Code Point (DSCP) for traffic from mobile stations. In summary, these APs act like a switch or router in that they provide many of the functions of such devices.

The downside of such APs is complexity. Fat APs tend to be built on powerful hardware and require complex software. These devices are expensive to install and maintain because of the complexity. Nevertheless, the devices have uses in smaller network installations.

Some Fat AP installations still use a controller at the back end for control and management functions. These controllers lead to a slightly scaled-down version of the Fat AP, called, not surprisingly, a Fit AP, discussed later.

Thin Access Points

As their name indicates, Thin APs are intended to reduce the complexity of APs. An important motivation for this reduction is the location of APs. In several enterprises, APs are plenum-mounted (and thus in hard-to-reach areas) so that they can provide optimum radio connectivity for end stations. In environments like warehouses, this is even more evident. For such reasons, network managers prefer to install APs just once and not have to perform complex maintenance on them.

Thin APs are often known as intelligent antennas, in that their primary function is to receive and transmit wireless traffic. They backhaul the wireless frames to a controller where the frames are processed before being switched to the wired LAN (see the Figure ‘Thin APs in Centralized WLAN Network Architecture’).

The APs use a (typically secure) tunnel to backhaul the wireless traffic to the controller. In their most basic form, Thin APs do not even perform WLAN encryption such as Wired Equivalence Privacy (WEP) or WiFi Protected Access (WPA/WPA2). This encryption is done at the controller the APs just transmit or receive the encrypted wireless frames, thereby keeping the APs simple and avoiding the necessity to upgrade their hardware or software.

The introduction of WPA2 necessitated encryption on the controller. Although WPA was hardware-compatible with WEP and required only a firmware upgrade, WPA2 was not backward-compatible. Instead of replacing APs across the enterprise, network managers could just backhaul the wireless traffic to the controller where the WPA2 decryption was done, and the frames were sent on the wired LAN.

The protocol between the AP and the controller for carrying the control and data traffic was proprietary. Also, there is no capability to manage the AP as a single entity on the Layer 2/3 network it can be managed only through the controller, to which the NMS can communicate through HTTP, SNMP, or CLI/Telnet. A controller can manage and control multiple APs, implying that the controller should be based on powerful hardware and often be able to perform switching and routing functions. Another important requirement is that the connectivity and tunnel between the AP and the AC should ensure low delay for packets between those two entities.

With Thin APs, QoS enforcement and ACL-based filtering are handled at the controller not a problem because all the frames from the AP have to pass through the controller anyway. Centralized control functions for ACLs and QoS are not new they were implemented in networks with Fat APs too. Such installations have controllers that act as the gateway for managing traffic from APs to the wired network. However, the controller function takes on a new dimension with Thin APs, especially with respect to the data plane and forwarding functions. The controller function subsequently was integrated into Ethernet switches that connected the wireless and wired LANs the motivation for the family of devices known as WLAN switches.

The Wireless MAC architecture in this scenario is known as the Remote MAC architecture. The entire set of 802.11 MAC functions is offloaded to the WLAN controller, including the delay-sensitive MAC functions.

Fit Access Points

Fit APs are gaining in popularity in that they try to take advantage of the best of both worlds that is, the Fat APs and the Thin APs. A Fit AP provides the wireless encryption while using the AC for the actual key exchange. This approach is used for newer APs that use the latest wireless chipsets supporting WPA2. The management and policy functions reside on the controller that connects to multiple APs through tunnels.

Also, Fit APs provide additional functions such as DHCP relay for the station to obtain an IP address through DHCP. In addition, Fit APs can perform functions such as VLAN tagging based on the Service Set Identifier (SSID) that the client uses to associate with the AP (when the AP supports multiple SSIDs).

Two types of MAC implementations are possible with Fit APs, known as the Local MAC and the Split MAC architectures. Local MAC is where all the wireless MAC functions are performed at the AP. The complete 802.11 MAC functions, including management and control frame processing, are resident on the APs. These functions include time-sensitive functions (also known as Real Time MAC functions).

The Split MAC architecture divides the implementation of the MAC functions between the AP and the controller. The real-time MAC functions include functions such as beacon generation, probe transmission and response, control frame processing (for example Request to Send and Clear to Send RTS and CTS), retransmission, and so on. The non-real time functions include authentication and deauthentication; association and reassociation; bridging between Ethernet and Wireless LAN; fragmentation; and so on.

Vendors differ in the type of functions that are split between the AP and the controller, and in some cases, even about what constitutes real time. One common implementation of a Fit AP involves local MAC at the AP and control and management functions at the AP.

Introducing Cisco Software-Defined Storage Solutions

November 23 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco & Cisco Network, #Technology, #IT, #Data Center

Today the Storage plays a more and more important role in the data center: from storing email messages and documents to saving business-critical information, intellectual property, and transaction detail. As businesses continue to become more connected, the old ways of storing and archiving data are changing to accommodate growing amounts of data and demand for anytime, anywhere access to information.

Historically, IT organizations transitioned from systems with individual disk drives to storage arrays that allowed disk drives to be grouped together to form a larger area of capacity. When fast and easy access to more capacity was needed, storage area networks (SANs) and network attached storage (NAS) emerged to deliver capacity over the network. More recently, integrated systems and hyper-converged infrastructure have been added to networks to simplify resource acquisition and deployment and facilitate easy scaling. As companies try to balance storage access, performance, and cost, software-defined storage is becoming more popular, taking this evolution a step farther.

Software-defined storage is the next phase of server virtualization technology, moving beyond virtual machines to virtual data stores. It combines industry-standard x86-architecture servers that are optimized for direct-attached storage (DAS) with a distributed software abstraction layer. This intelligent software transforms systems into a single, logical pool of cost-effective, scale-out storage resources that are easily integrated and managed within your data center.

Top 10 Facts about Cisco Wireless You Should Know

October 24 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Networking, #Cisco Wireless - Cisco Wireless AP, #Cisco & Cisco Network

In this article we will share 10 facts of Cisco wireless that you should know. Cisco Wireless related facts may make you shout out: “Really?”

really,top 10 facts...

If you have any suggestions for additions, please share with us or go to the original page to have a discussion.

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   1.1.1.118       Static  Yes    No  

management       1    untagged   1.1.1.111       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':

(Cisco Controller)

Welcome to the Cisco Wizard Configuration Tool

Use the '-' character to backup

Would you like to terminate autoinstall? [yes]:

<snip>

Management Interface VLAN Identifier (0 = untagged): 0

 

2) AP Image Names: w7 vs w8

ap image names:

w7 = standalone

w8 = lightweight

examples:

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

Autonomous/IOS/Standalone image:

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.

Example:

Same physical ap's, the first is shipped with a lightweight image, the second with an IOS image:

AIR-LAP1142N-A-K9

AIR-AP1142N-A-K9

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

Bootp-Broadcast: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

http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html#wp78157

These Access Points will not join a controller running code later than supported.

 

7) AP console settings

•9600 baud

•8 data bits

•1 stop bit

•No parity

*********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.

 

9) Multicast

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.

…More Discussion

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. 

http://www.cisco.com/en/US/docs/wireless/controller/5500/tech_notes/Wireless_Software_Compatibility_Matrix.html#wp99531 

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.

Introducing Cisco HDX (High Density Experience): Enhanced

October 7 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Cisco & Cisco Network

Cisco HDX Manages Performance on Crowded Wi-Fi Networks Wi-Fi traffic is everywhere.

Cisco HDX Manages Performance on Crowded Wi-Fi Networks Wi-Fi traffic is everywhere.

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.
