Putting the ‘Flexible’ in Flexible Radio Assignment

Putting the ‘Flexible’ in Flexible Radio Assignment

Flexible Radio Assignment-Cisco

Flexible Radio Assignment-Cisco

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.

802.11ac Wave 2’s Impact is World Wide, WHY?

July 13 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP, #Cisco & Cisco Network, #Cisco Technology - IT News

802.11ac Wave 2’s Impact is World Wide

802.11ac Wave 2’s Impact is World Wide

802.11ac Wave 2 APs

802.11ac Wave 2 APs

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 performa
nce.

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 eve
nts.

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 registra
tion

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.

Three Steps to Ignite Your Enterprise Digital Journey

July 7 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco News, #Cisco Technology - IT News

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.

Cisco Industrial Ethernet 1000 Series Switches, How It Works?

July 1 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall, #Cisco Technology - IT News

Cisco Industrial Ethernet 1000 Series Switches' ROLE

Cisco Industrial Ethernet 1000 Series Switches' ROLE

Cisco Industrial Switches have a big family, including the Cisco IE 2000, IE 3000, IE 4000 and IE 5000 Series Switches and the new IE 1000 Series.

The Cisco Industrial Ethernet 1000 Series---Lightly Managed Switches for Industrial Environments

The Cisco Industrial Ethernet 1000 (IE1000) Series Switches enable industrial network connectivity where traditional unmanaged switches lack the required performance and do not offer visibility and control.

Cisco IE1000 is a lightly managed Layer 2 switch designed for industrial users to better achieve productivity and network reliability, a primary element to business success.

The traditional industrial Ethernet switch of the past was a DIN rail unmanaged switch with few Ethernet ports to interconnect various nodes, including computer, HMI, PLC, I/O, drive, and sensors. The main challenge when deploying unmanaged switches is that it is difficult to monitor and troubleshoot issues that impact operational productivity. The IE1000 offers basic management for QoS, and security along with monitoring capability, which are essential in industrial environments.

The Cisco IE1000 Series has the option of Power over Ethernet (PoE) applications. Cisco IE1000 switches are designed to meet IEEE 802.3af (PoE) and 802.3at (PoE+) standards for network devices such as wireless access points, IP surveillance cameras, display monitors, and PoE-enabled industrial devices. One benefit of a PoE network solution is that it reduces the time and cost of having power cabling or outlets installed by certified electricians. The IE1000 PoE series is for industry users that seek flexible, low-cost, and easy-to-use installation solutions.

How It Works

As soon as you power up the IE1000, you can access the switch using a web browser to start the network connectivity. The IE1000 boots within 30 seconds from power up. It also allows you to monitor traffic flows, and Ethernet port utilization. You can administratively shut down or block unwanted devices in case of safety or security concern.

You can prioritize traffic on a per-port basis to assure that the critical traffic is delivered end to end with priority. In addition, the Cisco IE1000 transports industrial protocol traffic such as Ethernet/IP, PROFINET, and Modbus/TCP without extra provisioning. The support of SNMP, alarm relay, and syslog allows you to uncover errors before the network stops totally.

Solution Highlights and Capabilities

The Cisco IE1000 Series Switches support the features and capabilities sufficient for industrial usage, including:

Port density: 5, 6, 8, and 10

• FE copper or GE fiber uplink ports

• 4 or 8 Fast Ethernet downlinks

• Up to 8 PoE/PoE+ ports

• Data load optimization with VLAN awareness

IGMP and DHCP snooping

• Web GUI-based provisioning and monitoring with no need for extensive IT knowledge

• High reliability and five-year hardware warranty

Benefits

• Minimized downtime: troubleshoot, monitor, and diagnose with Web-based GUI tool.

• Improved network resiliency: spanning tree enables network link redundancy and fast link recovery.

• Increased network security: port security allows disabling ports to control what gets connected to the network.

• Critical traffic prioritization: guaranteed delivery of mission critical end devices traffic.

• Reduced overall TCO: VLANs allow for logical segmentation in a single switch, which reduces total number of switches needed.

Use Case Examples

• Machine builders: Connects complex I/O and automation gears

• Panel builders and panel shops: for electricians to manage Ethernet connectivity.

• PoE solution for smart cities: Connects Wi-Fi access points and IP camera in locations without flexible power outlet or in spaceconstrained roadside cabinets.

Mix Cisco Access Points? It’s Okay

June 8 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Technology - IT News, #Cisco Wireless - Cisco Wireless AP

Don’t Sweat the Small Stuff: It’s Okay to Mix Cisco Access Points

Don’t Sweat the Small Stuff: It’s Okay to Mix Cisco Access Points

FCC 14-30 is a hot topic these weeks. In early June 2016, the FCC published FCC 14-30 Order, which now allows the use of three additional channels (120, 124, and 128) as well as other power adjustment and updated DFS regulations. Cisco’s compliance with new rules requires the assignment of hardware to a regulatory domain, indicating which rules the device complies.

In the following part, let’s read the reviews written by Jim Florwick (a member of the Technical Marketing Engineering team for Cisco's Wireless Business Unit). He talked about Why “It’s Okay to Mix Cisco Access Points”

Don’t Sweat the Small Stuff: It’s Okay to Mix Cisco Access Points

The new –B regulatory domain was designed to take the place of –A so that access points will be compliant with the FCC 14-30 Order. Per the FCC order, access points shipped before June 1, 2016 are grandfathered to adhere to –A requirements. Access points shipped after the June 1 date must meet the –B requirements. This includes changes in DFS detection requirements, which must re-certify according to the new rules.

I’ve been hearing from a lot of customers who don’t want to mix the two regulatory domains in their networks. But there simply is no reason not to do so.

There are a few nice things in a –B access point that aren’t available in an –A access point. Things that we all want: more 5 GHz channels and more power in U-NII 1. However, other than those minor changes, the –B and –A access points are the same. There are absolutely no operational issues in running both –A and –B on the same controller or controllers.

For example, let’s say you’re adding some access points or building out a new area – and you mix –A and –B access points, what will happen in terms of operations?

If the new channels aren’t added to the DCA list—and by default, they are not—they will not be assigned to any of the –B capable access points. If the new channels are added to the DCA list, it will only be assigned to the –B access points. This won’t be a problem as the clients will still use 120, 124, 128 where it’s available.

I have been in this industry for a long time and I’m not aware of any clients that support U-NII 1, 2, 3 that have failed in these channels. If, for some reason this does happen, simply remove the channels. No harm, no foul.

That leaves different allowed transmit (TX) power. There will be no issues here either – since TPC still works the same as it always has. The Cisco access point product line still operates with a mix of allowed powers in the 5 GHz UNII bands under the –A rules. The Neighbor Discovery Protocol is normalized for this reason and Radio Resource Management (RRM) works just fine. There are no known issues with mixing –B and –A radios in the same air on the same controller. If a user wants to stay consistent about power implications, simply set TPC Max to enforce max power to –A globally and in RF Profiles when in use.

In the last sentence I talked about consistency, and there are a lot of customers—myself included—that just don’t like the idea of a mixing anything. I go so far as to stay away from milkshakes and just eat ice cream cones, when I want a cool treat. But the reality is this is not like mixing Cisco Aironet 1130 and Aironet 3700 Access Points in the same room. Once your –A and –B access points are plugged in and running no one would ever know that a mix existed.

We don’t have operational hiccups absorbing this change like some of our other competitors. At Cisco, we’ve been running mixed environments in Alpha production networks since the Cisco AP 1810 was in development—and that’s a fair amount of time to find irregularities and observe errors. Cisco Mobility Express is built on a –B access point, and supports the –A access points. These devices have been tested over thousands of hours and work as expected.

There is really no reason other than just the perception of a mix to be worried. With that being said, I’m heading down to the ice cream shop and enjoying a frosty milkshake. I hear that they’re really great!

  • Automation. This area is centered on IT speed and simplicity. Today’s networking professionals are CLI jockeys, but that will offer less value as time goes on. The network is evolving to software with software-defined networking, open APIs, network function virtualization and more. These new technologies provide networking IT with unprecedented agility that helps IT deliver business requirements faster and can free up cycles to support more strategic projects for their organization.
  • Security. While digital technologies have opened up new opportunities, they have also introduced a level of risk. As we see the proliferation of mobile devices and cloud adoption, the network perimeter is evolving and the attack surface has the potential to grow significantly. To combat that risk, networking professionals will be able to offer the business a new approach to inject security pervasively through the network, which can be the sensor and enforcer of security threats.

Using DHCP and DHCP Option 82

March 30 2016 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network, #Cisco Technology - IT News

DHCP Option 82 Operation

DHCP Option 82 Operation

DHCP is short for Dynamic Host Configuration Protocol. We know that DHCP is used in LAN environments to dynamically assign host IP addresses from a centralized server, which reduces the overhead of administrating IP addresses.

I’ve read an article “DHCP Snooping and DHCP Snooping Configuration” that is about a CCIE’s experience. In that article it also shares the DHCP Option 82 concept.

In this article we will share some info of using the DHCP Option 82.

DHCP also helps conserve limited IP address space because IP addresses no longer need to be permanently assigned to client devices; only those client devices that are connected to the network require IP addresses. The DHCP relay agent information feature (option 82) enables the DHCP relay agent (Catalyst switch) to include information about itself and the attached client when forwarding

DHCP requests from a DHCP client to a DHCP server. This basically extends the standard DHCP process by tagging the request with the information regarding the location of the requestor. (See the Figure “DHCP Option 82 Operation”)

...

The following are key elements required to support the DHCP option 82 feature:

• Clients supporting DHCP

• Relay agents supporting option 82

• DHCP server supporting option 82

The relay agent information option is inserted by the DHCP relay agent when forwarding the client-initiated DHCP request packets to a DHCP server. The servers recognizing the relay agent information option may use the information to assign IP addresses and to implement policies such as restricting the number of IP addresses that can be assigned to a single circuit ID. The circuit ID in relay agent option 82 contains information identifying the port location on which the request is arriving.

Note:

1. The DHCP option 82 feature is supported only when DHCP snooping is globally enabled and on the VLANs to which subscriber devices using this feature are assigned.

2. DHCP and the DHCP option 82 feature have not been validated in the lab for EttF version 1.1. At this time, Cisco recommends considering only DHCP with option 82 for the application servers at level 3.

Is It Cisco ClientLink 4.0 or ClientLink 3.0?

Optimize Your Mixed-Client Wi-Fi Network

Optimize Your Mixed-Client Wi-Fi Network

The Cisco ClientLink Advantage

The Cisco ClientLink Advantage

Mobile devices are so popular today, which range from laptops, tablets, smartphones to others. And now all kinds of mobile device types now connect to your wireless LAN. All these mobile devices might use a mix of new and old Wi-Fi technologies – 802.11ac, 802.11n, and 802.11a connections – for access. To keep the older and slower clients from impeding the performance of newer and faster 802.11ac Wave 1 and 2 connections, there is Cisco ClientLink.

ClientLink is a beamforming capability built into Cisco Aironet wireless LAN access points. When the access point (AP) concentrates signals toward the receiving client, that client is better able to “hear” the AP’s transmission, so throughput is greater. ClientLink also enhances performance in the uplink (client-to-AP) direction, so that the AP can also better hear the client communications. The result is improved performance in both directions.

By comparison, many competing 802.11ac-capable APs offer uplink-only enhancements, from client to access point. Many 802.11ac-capable AP suppliers also base their downlink enhancements on the optional transmit beamforming (TxBF) feature in 802.11ac, which requires TxCBF support in the client device to operate. Cisco ClientLink technology is unique in offering both uplink and downlink performance improvements, and it doesn’t require any special capabilities in the client device to work.

ClientLink works with all client technologies. It makes sure each client type always operates at the best possible rate, as determined by the 802.11 access technology supported, network conditions, and the distance of the client from the Wi-Fi AP. ClientLink helps maintain maximum client rates even at cell boundaries, when clients are farthest away from the AP.

How to Get the Most from 802.11ac?

The 802.11ac standard inherently provides performance increases compared with earlier 802.11 technology versions. But because 802.11-based equipment is backward-compatible with older versions of the standard, it pays to run a mixed-client network to get the most out of your device investments. At the same time, however, your older clients can delay communications for the faster 802.11ac clients, hindering 802.11ac performance benefits.

Cisco ClientLink overcomes this issue for more reliable mobile experiences. In Aironet 802.11ac APs, ClientLink uses four transmit antennas to focus transmissions in the direction of the Wi-Fi client, surpassing the industry norm. This support improves downlink signal-to-noise ratio (for better client “hearing”) and boosts the data rate over range so you can reduce coverage holes and enhance overall system performance. Table 1 illustrates the Cisco performance advantages of using ClientLink technology.

You get beamforming enhancements across your entire client population of new and old devices: Cisco ClientLink beamforming works with all client types, and IEEE-standard transmit beamforming (TxBF) is also built into all Cisco Wi-Fi-Certified 802.11ac access points to benefit the 802.11ac clients that support it.

ClientLink also works with multiuser multiple input, multiple output (MU-MIMO), part of the 802.11ac standard that enables concurrent transmissions between an AP and multiple 802.11ac client devices that also support MU-MIMO. As a result, Cisco ClientLink can now also provide performance boosts across a mixture of 802.11ac, 802.11 n, and 802.11a clients to further benefit your entire wireless network.

The wireless difference is in the implementation details. Turn to Cisco ClientLink-enhanced APs to get best performance from all Wi-Fi clients on your network.
