To Go Ahead with Cisco

July 31 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

 

After four years of hard work it’s time to celebrate – the London 2012 Olympic and Paralympic Games are finally here. But for Cisco, and the athletes, challenges still lie ahead…

 

As the London 2012 procession makes its final push to Stratford, the country is full of anticipation and excitement.

 

The London 2012 Festival has transformed our streets with music, events and performances building up to tomorrow’s Opening Ceremony.

 

Yet for the athletes at the heart of the Games, such as Gold medalist Tim Brabants, this is a time to remain calm and focused. Tim’s most critical work begins when the starting gun is fired. And with potentially 8 billion collective eyes watching every stroke of his kayak paddle in full HD, now is not the time to lose concentration.

 

Tim is not alone in being ready for this moment. Cisco–the Official Network Infrastructure Provider for London 2012 has been working hard behind the scenes to deliver the cutting- edge infrastructure needed to make sure the Games run without a hitch. For example, they will seamlessly connect nearly 100 different locations across the UK into one virtual Games venue while managing the network traffic of 200,000 visitors and media personnel via 1,800 wireless access points. Like Tim, Cisco faces a monumental task that leaves no room for error. Fortunately they are just as prepared.

 

For Cisco, getting it right first time is imperative to the success of the Games.

 

So while the world’s most famous Olympians take centre stage, behind the scenes a much less celebrated, yet vital, team will ensure that spectators around the world enjoy and share what’s set to be the most connected Games ever.

 

Cisco’s philosophy “Built for the Human Network” could have been made for this moment. They believe technology shouldn’t define what we do, but provide the backdrop that makes human excellence possible.

 

Combined with a track record that includes the Beijing 2008 Games and FIFA World Cup 2010 – as well as working with top Fortune 500 Companies, telecoms and utility providers – Cisco has the experience and passion necessary to embrace their biggest challenge yet.

To start, they helped build the London Organising Committee of the Olympic Games (Locog) from scratch.

 

Working with their fellow technology partners, Cisco, helped to develop Locog’s conferencing and collaboration software. Starting with just two employees working on the Games in 2009, Cisco now has upwards of 80 employees and volunteers all dedicated to the smooth running of Locog and London 2012.

 

Four years on, Cisco has succeeded in creating one of the most robust, secure and available network infrastructures the world has ever seen. The stadia, venues and infrastructure built around the Olympic Park are second to none and Cisco’s borderless network infrastructure will connect it all together.

 

The Challenge

“The IT systems for London 2012 will process 30 per cent more information than any other Games in history and Cisco networking is at the heart of it,”says Neil Crockett, managing director for London 2012 at Cisco Systems With a huge increase in network traffic from previous Olympic Games, Cisco is braced to provide recordbreaking amounts of data, video and voice via a fully converged IP network for the very first time ever. With 1,800 wireless access points, 16,500 IP telephones, 65,000 active connections and 80,000 data ports they are fully prepared for the network demands of the 11 million reporters, fans, athletes and staff descending upon London this summer.

 

The network infrastructure will not only cope with staggering amounts of data, but will also be responsible for connecting nearly 100 locations – including 36 competition venues, 20 further venues such as the Olympic Village and operations centre, and around 50 other spectator and athlete sites including transport hubs, training grounds and ticketing booths.

 

A mission-critical network infrastructure also requires round-theclock technical support. Cisco is ready to provide rapid-response expert assistance and support to their fellow technology partners in their roles, to ensure successful delivery of the London 2012 Olympic and Paralympic Games. What’s more, they are upping their support to their non-Olympic customers, helping them keep their businesses running as usual during this busy time.

 

Game-changing technology

In 2008 Tim Brabants took Britian’s first ever kayaking Gold – but no one witnessed his historic victory live on a tablet device. Unsurprisingly, technology has changed a lot since Beijing.

 

High Definition has become virtually synonymous with sports broadcasting, and smart phones have worked their way into our psyches, becoming indispensable to our lives.

 

Part of Cisco’s challenge was anticipating how technology would evolve over four years, while developing infrastructure to cope with future innovations.

 

Cisco has created network infrastructure to meet new consumer demands – such as watching the Games in full HD, or relying on quick and secure network connections.

 

Cisco Games face brings a human touch to Cisco’s offering. Visitors to the Cisco Cloud in Stratford can upload their favourite photos of the Games in order to create a 3D artwork commemorating their unique experience of London 2012. Londoners aren’t the only ones who can join in the fun – the application is also available online for fans nationwide.

 

Looking beyond tomorrow

With technology continually evolving, and sustainability and urban regeneration high on the agenda, Cisco needed vision to create a network infrastructure that would take the 2012 Games, London and the UK into the future.

 

The British Innovation Gateway (BIG) is the start of Cisco’s five-year effort to drive economic growth through high-tech innovation. Launched in January 2011 by David Cameron and global CEO John Chambers it will repurpose the infrastructure of London 2012 to foster entrepreneurship and enable small and medium high-tech businesses in a sustainable and scalable way.

 

“I welcome this major statement of support from Cisco,” says David Cameron. “This will help create many new jobs and opportunities, and support our drive to diversify our economy and generate sus tainabl e economic growth.”

 

Cisco’s network infrastructure will also connect research clusters, higher education establishments and science parks all over the country. They will continue to support STEM initiatives in schools, inspiring young people to study maths and sciences. By encouraging collaborations and innovation in this crucial area of the economy, Cisco will continue to have a hand in London’s 2012 legacy for years to come.

 

Over the final hurdle

Coordinating the network infrastructure for an event equivalent to 46 World Championships is no small accomplishment – but Cisco is not resting on its laurels. Their staff will continue to work around the clock throughout the Games to make sure the hard work dedicated to this Herculean effort results in a personal success worthy of Gold.

 

“Preparation is very, very key to ultimate performance,” says Tim Brabant as he looks forward to his own challenge at Eton Dorney. It’s a sentiment perfectly echoed by Cisco over the past four years. And now everything is finally in place – the network infrastructure tested to the limits.

 

They’ve completed two extensive technical rehearsals.

 

They’ve run over 200,000 hours of testing. They’ve passed the final sign off from the London 2012 Organising Committee.

 

Now let’s see what Cisco, and Great Britain, can do.

How to Select Your Cisco Products?

July 30 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco & Cisco Network

 

Today, WAN technologies most often take advantage of high-speed connections, such as T-1 and E-1. Additional WAN technologies exist, including Frame Relay, ISDN, and dial-up asynchronous connections. ISDN or dial-up is used if infrequent connection is made. If a connection is used for more than two to four hours, you should use a Frame Relay or a leased line. Based on the different services available through the service provider, you can select Cisco products that can fulfill your office requirements.Select-Your-Cisco-Products.jpg

Selecting Hubs

Cisco has various hub products. You can select hubs according to the type of connection required. Higher-end hubs offer network management port and console connections, middle-end hubs offer both 10 Mbps and 100 Mbps auto-sensing connections, and the lower-end hubs offer only 10 Mbps connections. Examples of fast hub series of Cisco are Cisco Fh100, Cisco Fh200, Cisco Fh300, and Cisco Fh400. Examples of micro hub series are Cisco MH1500 and Cisco MH1528.

Selecting Routers

Routers are the most popular Cisco products. To select a router, you must first know the port density and the interface speed required based on the LAN or WAN technologies used. In addition, you must identify the capacity and performance requirements of your business. The cost of the router varies according to the features you select.

Selecting Switches

A switch can be used instead of a hub in newer networks. Most switches are configured to limit collision domains, which often provides a limited security feature because users will not be able to sniff traffic as easily as in a standard hub-based network. This feature can cause confusion when using a network sniffer to analyze traffic. It is possible, however, to analyze packets on a switched network by enabling mirroring on the switch, or by using a dedicated port that allows authorized users to view all network traffic. It is important to consider whether you need 10, 100, or 1000 Mbps for each desktop or to connect between switches. To select a switch, you must consider various issues, such as business requirements, requirements for inter-switch links and trunking, port density, and type of user interface.

Product Selection Criteria

When selecting the right products for any network environment, keep the following considerations in mind:

  • Will the device be used as a core device, distribution device, or access device?
  • Does the device provide the functions that your business requires?
  • Does the device have adequate number of ports and the right mix of interfaces as required by your business?
  • Do you have to pay a lot for installing the device or can it be easily installed?
  • Can the device be centrally managed from an SNMP Management station or do you have to physically access the device to manage it?
  • Is the migration path easy?
  • How well does the device handle redundancy requirements?
  • Do you have to change your existing infrastructure, such as cabling or existing devices, to install the new device? You may use the Cisco’s official website to gather more information to select products based on your requirements.

D. enter the "boot system flash c2500-js-l" command in the configuration file

 

Answers

1) ABD. If a workstation moves, there is a good chance the move is within the same VLAN. If we have a good design of a single subnet within each VLAN, there will be no need to reconfigure the workstation with a new layer 3 addresses. Each VLAN defines a broadcast domain.

2) BC. Full duplex Ethernet uses 2 pair of wires just like half duplex Ethernet. With full duplex, 1 pair is dedicated for one machine to transmit and the other pair is dedicated for the other machine to transmit. It only works on point-to-point links, no hubs are allowed.

3) C. Network application data is encapsulated in a segment. A segment is encapsulated in a packet. A packet is encapsulated in a frame. The frame is sent as bits across the wire. At the other side of the communication, the encapsulation is stripped off layer by layer until the receiving computer has obtained the Application layer information.

4) CE. The address, although it looks like a broadcast, is not. By virtue of its subnet mask, the address is simply a host on the very large 172.16.16.0 255.255.240.0 network.

5) ABD. The subnet mask is used to identify the network portion and the host portion of the address. For example, when you use the default subnet mask of 255.255.0.0, the first two 255.255 octets represent the network address and the last two 0.0 octets represent the host addresses. These octets are representation of binary numbers where 11111111 equals 255. In binary, the host portion of the address cannot be all 1's or all 0's. This is a class B address, so the last 2 octets represent the host portion of the address.

6) ADE. Routers are more complex devices than switches or bridges. This complexity gives more administrative control and functionality than switches or bridges, but slows down the device, which increases latency. Since VLANs are individual broadcast domains, routers are used for inter-VLAN communication.

7) C. Address resolution protocol is used by TCP/IP to find the MAC of a station that you already know the IP address of. To send a packet over Ethernet, Token Ring or FDDI, you must have a Data Link header containing a destination MAC address. RARP is the opposite of ARP, resolves the IP address to a known MAC address. BOOTP, DNS and DHCP offer remote booting, name services, and dynamic IP addressing services.

8) CD. The "show int" and "show interface" command is an abbreviation of the command "show interfaces" and lists all the interfaces on the router along with current statistics for these interfaces.

9) ABC. When the hardware is up that means that we are receiving carrier detect from the other side. When the line protocol is down that means we are not able to actually send or receive frames on that line, which could be a connector, keep alive or clock rate problem.

10) B. If the last 4 bits of the configuration register equal 0000, then the router will boot into ROM monitor mode and not load any operating system. Entering "boot system rom" in the configuration file will cause the router to load the operating system from ROM (assuming the configuration register ends in 0x2 through 0xf). ROM in all caps is the accepted way to notate read-only memory; while not case sensitive the lower case rom is normally used at the command line in the Cisco IOS.

Cisco Acquires Virtuata for Cloud Security

July 18 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

We caught up with tech-industry analyst Zeus Kerravala for feedback on Cisco's acquisition of Virtuata. He believes Virtuata fits in well with Cisco's overall acquisition strategy, which inks big deals and small deals when necessary to fill out its portfolio. In fact, Cisco has acquired five companies this year, four of them focused on the data center and networking.

 virtuata.png

Cisco quietly acquired a privately held company that has been developing capabilities for securing virtual and cloud environments. Cisco did not disclose the financial terms of the deal.

 

Virtuata secures machine level information in data centers and cloud environments. Together, Cisco and Virtuata will enable consistent and enhanced security for virtual machines allowing customers to accelerate the deployment of multi-tenant, multi-hypervisor cloud infrastructures, according to Hilton Romanski, a vice president and head of Cisco's Corporate Business Development.

 

Filling Out UCS

"Cloud and virtualization are significant disrupters in the market. When customers move to these environments, security concerns arise where infrastructure is shared across multiple applications, business units or even organizations," Romanski said.

 

"As more and more business applications move to virtualized platforms, security and isolation become necessary conditions at the virtual machine level. This acquisition is highly complementary to Cisco's vision of a unified data center that securely connects people and businesses with applications and data through virtual and cloud environments."

 

Cisco is acquiring both the technology and the talent that makes up Virtuata. The company said the combination offers a unique infrastructure expertise in virtualization, cloud and security domains to Cisco's data center and cloud product portfolio, including its Unified Computing System (UCS) and Nexus-based Unified Fabric portfolio.

 

Cisco's UCS is a converged data center platform that delivers programmable infrastructure in bare-metal, virtualized and cloud computing environments. The system integrates Cisco servers and network and I/O resources into one system.

 

The Right Security Move

"The Virtuata acquisition reinforces Cisco's build, buy, partner innovation framework and supports our strategy of providing best-in-class solutions for our customers," Romanski said. "It is well-aligned to our strategic goals to develop innovative virtualization, cloud and security technologies, while also cultivating top talent."

 

We caught up with Zeus Kerravala, principal analyst at ZK Research, to get his take on the small acquisition. He told us Virtuata fits in well with Cisco's overall acquisition strategy, which inks big deals and small deals when necessary to fill out its portfolio. Cisco has acquired five companies this year. Four of them have been focused on the data center and networking.

 

"This fits squarely into the cloud and data center space, which has been a big focus for Cisco. That's the area of IT that's been the most opportunistic right now because you've got this coming together of compute, storage and networking gear. Almost all vendors in that space, be it Dell, HP or Cisco, are fighting for more and more footprint," Kerravala said.

 

"With security being by far the biggest inhibitor to broader cloud adoption, this is probably the right move for Cisco to make. I think Virtuata is a good addition to its cloud portfolio. It makes a lot of sense for them."

Cisco Routers---Linksys EA4500 Review

July 16 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

It's not every day simple Wi-Fi routers make headlines by angering just about all of Internet but that is exactly what Cisco managed to do with its latest packet punting products.

 

Cisco introduced a new and innovative (yes, really) feature called Connect Cloud with its spruced-up home router range. That's a nebulous name but Connect Cloud lets you shift management of the router away from the device itself, to the web so that you can get to your home network from everywhere.linksys-ae4500.jpg

Also, Cisco made an app market for the routers so that developers could code useful programs that could take advantage of Connect Cloud. This is actually a pretty cool concept, although the apps are far and few between currently and mainly aimed paranoid people wanting to monitor and filter traffic.

 

However, the way Cisco launched Connect Cloud into this world is a case study in how not to do these things.

 

First, Cisco pushed out the service automatically as an update for the firmware that controls routers.

 

That is, Connect Cloud was installed on existing Cisco routers without anyone realising what had happened until they went to take a look at the management web page and discovered that instead of ending up at the box itself people were redirected to a site on the Internet.

 

In order to manage your router, you had to sign up at the Cisco Connect Cloud site. If you didn't, it was impossible to manage the router.

 

That's drastic enough, and should never happen without Cisco customers consenting to the change.

 

It gets worse though: if you signed up to the Connect Cloud service, the initial terms and conditions banned customers from using it "for obscene, pornographic, or offensive purposes" and also for infringing on "another's right, including but not limited to intellectual property rights".

 

The terms and conditions also said that Cisco would monitor the network traffic and Internet history of customers.

 

Adding insult to injury, Cisco threatened to disconnect users who didn't comply with the harsh terms with disconnection from the Connect Cloud service.

 

Long story short, the whole thing blew up spectacularly as enraged Cisco customers vented their fury online.

 

Cisco scrambled to repair the damage and has since removed some of the offending clauses, saying they were inserted by mistake. It remains to be seen if this is enough to restore the trust Cisco lost with customers, some of which are now installing alternative firmware on their routers.

 

Get off my cloud
The Connect Cloud furore happened before I received my review sample of the Cisco Linksys EA4500, the current range topping home Wi-Fi router from the US networking company, and I was wondering what I'd make of it.

Let's deal with the Connect Cloud feature first: I like the idea, but not Cisco's implementation of it.

Having remote access to your home network across the Internet and by using Android and iOS apps is a useful idea as it brings your network to the cloud in seamless fashion. 

Connect Cloud needs an active Internet connection for set up however as well as a computer and don't lose that set-up CD that comes with the EA4500. You can configure the EA4500 without it, but with Connect Cloud in the mix and separate passwords for that service and the router itself, it's a complicated process.

 

Also, Connect Cloud is hosted in the United States. Being that far away from New Zealand, the Connect Cloud interface is sluggish to use. The built-in speed test feature shows low results as it's also in the US and the whole Connect Cloud service is focused on Americans.

 

If like many people you put the EA4500 behind a DSL modem and set the router to Bridge mode to avoid having two separate networks that can't talk to each other, Connect Cloud gets confused and randomly thinks your Internet connection is down - in which case you have to log locally to the router instead, so don't lose the password for the EA4500.

 

Normally, I never have to spend this much time with the admin interface on a router, and Cisco really needs to rethink the Connect Cloud concept.

 

The EA4500 is otherwise a good looking little box that provides fast throughput for wireless in the 2.4GHz and 5GHz bands: I was able reach 70-75Mbps in the former band, and 120-130Mbps in the latter, good figures both.

 

A fast Gigabit Ethernet network switch with four LAN is also included, and a fifth Internet port is included too, which is entirely logical for the EA4500 that's aimed at streaming high-definition video and other large files.

 

But, Cisco: why is the USB port for hard drives (and printers) only a 2.0 variant and not a newer 3.0 one? I could squeeze 175Mbps out of the USB 2.0 port, but USB 3.0 is much faster and better suited for the EA4500 which has a built-in media and ftp server for file sharing.

 

I also encountered a bug that meant my upload speed halved if I used the Internet port on the EA4500 to connect to my VDSL2 router. Not using the Internet port sorted out the problem. The problem has been reported to Cisco and I'll update the review if and when it is sorted out.

 

The Cisco EA4500 is a premium Wi-Fi router that performs well enough, but needs some annoying foibles fixed. This includes Connect Cloud.

 

What's good
Nice design
Good performance
Full range of features

Cisco to Break the 1-Gigabit Barrier on Enterprise WiFi Networks

July 12 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

The networking giant will introduce a 1G-bit access point in 2013 to accommodate the need for faster wireless enterprise networks, but competitors are expected to be close behind.wireless-network.jpg

Cisco Systems says it will be the first networking vendor to deliver 1-gigabit-per-second speeds on enterprise wireless networks when it introduces an 802.11ac-based access point next year, but a few other things have to also happen before that actually means something.

 

The 802.11ac WiFi standard, currently under development by the Institute of Electrical and Electronics Engineers (IEEE) standards body, would be the successor to the predominant 802.11n standard today. Cisco officials said 802.11ac is needed to handle the growing number of devices seeking wireless access to corporate networks as the smartphones and tablet computers people are bringing to work lack an Ethernet jack to plug into the wired network. 

 

They said Cisco will introduce an 802.11ac module in the first half of 2013 that can be plugged into an existing Cisco Aironet 3600 access point that runs on the 802.11n standard now, said Sujai Hajela, vice president and general manager of the wireless networking business unit at Cisco.

 

“It allows [customers] to upgrade and not have to go through the guesswork of, ‘Should we upgrade to 802.11n or go with 802.11ac?’ You can invest in 11n now and upgrade to 11ac with a new radio,” Hajela said, referring to the module. “It’s a way of future-proofing your network.”

Wired networks already operate at 1G-bps speeds and are quickly accelerating to 10G, 40G and even 100G speeds, but Hajela said Cisco would be the first to break the 1G-bps barrier on a wireless local area network (WLAN).

 

However, a few other things have to happen before end users can actually experience 1G-bps speeds on their wireless networks, said Mike Spanbauer, principal analyst at Current Analysis, a research firm.

 

First, the 1G-bps speeds Cisco is touting are dependent upon a number of variables, including radio frequency (RF) interference, the kind of antenna used, the strength of the endpoint radio and other factors. Second, 11ac-capable access points won’t mean much unless 11ac-enabled devices are there to connect to them. The smartphones, tablets and laptops currently shipping are still based on the 802.11n standard, although Spanbauer expects the endpoint devices will be on the market by the time the access points are.

 

And although Cisco may claim bragging rights as the first networking vendor to publicly declare a coming 1G-bps WLAN access point, Cisco’s competitors—particularly Aruba Networks and Hewlett-Packard—may not be far behind, he said. All three vendors were placed in the “Leaders” quadrant in a June Magic Quadrant report from research firm Gartner profiling the top vendors in both the wired and wireless networking equipment markets.

 

“I think that every one of those vendors is very aggressively working on 11ac themselves,” said Spanbauer.

 

“[HP] is working on our 802.11ac portfolio of access points,” said Kevin Secino, a marketing manager within HP Networking, but emphasized that “our business objective is to be standards-compliant.” Furthermore, he noted that the 802.11ac standard is still in development and may not be finalized until sometime in 2013 anyway.

 

HP’s experience in wireless access points dates back to its acquisition of a company called Colubris in 2008, whose technology went into HP’s ProCurve line of wireless devices. It entered into a joint venture with 3Com to sell a line of wireless devices called the H3C line, which was followed by HP’s acquisition of 3Com in 2010.

 

While noting that competitors are expected to introduce 1G-bps access points in competition with Cisco, Current Analysis’ Spanbauer lauded Cisco for enabling its existing Aeronet 3600 WLAN access point devices already shipping and installed to be easily upgraded to 802.11ac when the time comes.

 

“It’s important to know that your wireless LAN vendor is going to be supporting and moving forward with the next specification,” he said.

 

HP’s Secino, meanwhile, said the company “has been very good in ensuring that customers’ investments are protected.”

How to Route Multiple VLANS through a Cisco Aironet 1300?

July 5 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Wireless - Cisco Wireless AP

Enable VLAN or Virtual Local Area Network forwarding through a Cisco Aironet 1300 by connecting to the Aironet Web administration interface. The Cisco Aironet 1300 can bridge network segments and forward VLANs between network segments once the Aironet native VLAN matches that of the switch connected to the Aironet. Configure the Cisco Aironet Native VLAN and VLANs you want to forward using a Web browser.

Cisco Changes Privacy Policy for Linksys Routers after Uproar

July 3 2012 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco News

Cisco Systems said a privacy policy for the Cisco Connect Cloud service that alarmed some customers was a mistake and has been removed.

 

The cloud service, which among other things allows users of some Wi-Fi home routers to manage their devices from away from home, went live last week and was included in an automatic firmware update to those routers. That brought a flood of complaints to online forums about both the firmware update and the privacy document, which said Cisco might track and share information about customers' Internet use and other data.

 

"We removed content that could have been misinterpreted as being inconsistent with Cisco's privacy statement based on a selective analysis," Cisco said in a statement.

 

"In a nutshell, this was just a mistake," Cisco spokesman David McCulloch said.

 

The specific privacy policy for the cloud service is contained in a "Cisco Connect Cloud Supplement," that expands upon Cisco's general corporate privacy policy. There is a link to the supplement on the right side of the general privacy page. Parts of the supplement, including the reference to collecting Internet history, have been removed. McCulloch said he could not immediately explain how the stricken language was included by mistake.

 

Some users of the Linksys EA3500 and EA4500 routers wrote on online forums last week that Cisco apparently had updated the firmware on their routers automatically without their consent. The new firmware prompted them to start managing their routers through the Cisco Connect Cloud service, which administers a router over the Internet instead of directly over the wireless LAN. Some users said they weren't able to keep managing their routers locally except through a limited interface that lacked features they were used to.

 

Along the way, one user pointed out a section of the privacy policy for Cisco Connect Cloud that said the company might keep track of a variety of information including Internet history and might share "aggregated and anonymous user experience information" with service providers and other third parties.

 

The updated privacy supplement for the cloud service says, "Cisco may collect and store detailed information regarding your network configuration and usage for the purpose of providing you technical networking support." It says that data will be associated with the customer only when he or she provides an ID number, randomly generated and under the user's control, to the support representative.

 

An administrator on the Cisco Home Community forum subsequently posted a link to instructions for downgrading the routers' firmware and opting out of future automatic upgrades.

 

But Cisco also responded to the complaints with a dedicated post to its official blog on Friday.

"Cisco Connect Cloud was delivered only to consumers who opted in to automatic updates. However, we apologize that the opt-out process for Cisco Connect Cloud and automatic updates was not more clear in this product release, and we are developing an updated version that will improve this process," Cisco Home Networking Vice President and General Manager Brett Wingo wrote in the blog post. The post directed customers who wanted to return to the traditional Linksys management software to call the Linksys customer support line.

 

The blog post also partly addressed the questions about the privacy policy but didn't say the "Cisco Connect Cloud Supplement" had been changed. McCullough said on Monday that the blog might be updated.

 

 Linksys is a brand used on products from Cisco's Home Networking Business Unit.
