What’s the Cisco IOS?
Cisco IOS (originally Internetwork Operating System) is the software used on the vast majority of Cisco Systems routers and current Cisco network switches. (Earlier switches ran CatOS.)
IOS is a package of routing, switching, internetworking and telecommunications functions tightly integrated with a multitasking operating system.
Cisco IOS is versioned using three numbers and some letters, in the general form a.b(c.d)e, where:
a is the major version number.
b is the minor version number.
c is the release number, which begins at one and increments as new releases in the same a.b train are released.
d (omitted from general releases) is the interim build number.
e (zero, one or two letters) is the release train identifier, such as none (which designates the mainline, see below), T (for Technology), E (for Enterprise), S (for Service provider), XA as a special functionality train, XB as a different special functionality train, etc.
Most Cisco products that run IOS also have one or more "feature sets" or "packages", typically eight packages for Cisco routers and five packages for Cisco network switches. For example, Cisco IOS releases meant for use on Catalyst switches are available as "standard" versions (providing only basic IP routing), "enhanced" versions, which provide full IPv4 routing support, and "advanced IP services" versions, which provide the enhanced features as well as IPv6 support.
Each individual package corresponds to one service category, such as IP data, Converged voice and data, Security and VPN. More info visit White Paper: Cisco IOS and NX-OS Software Reference Guide
A&Q about Cisco IOS (from Yahoo Answer)
Q: Help needed to upgrade my cisco switch ios?
I have connected my switch via console cable, I have set up a tftp server on my PC when I try to update the ios it keeps timing out.
A: First, your computer with the tftp server and the switch need to be connected via the network. When the switch pulls the image, it's not through the console cable, but rather an ethernet port.
Second, your new IOS image needs to be in the correct folder on your local hard drive so the tftp server can reach the file and serve it to clients that ask. This varies greatly by tftp server, so I can't give you clear directions for how to do this.
Third, your switch needs an IP address assigned to a vlan interface. Typically, vlan 1 is used, but more advanced users can use a different one. The configuration usually looks like:
interface vlan 1
ip address w.x.y.z 255.255.255.0
To do a little troubleshooting, try pinging your computer from the switch and then ping the switch from your computer. Due to firewalls, this may or may not work, but it's a good tool.
Lastly, once you are sure that connectivity is in place, you issue the command "copy tftp flash" from the switch. The switch will ask you the IP address of the tftp server, then the filename, and then it will probably ask you if you want to erase the flash. You should usually press "enter" to confirm "yes" to erase the flash, otherwise you'll run out of room in the memory. If you do not receive the question to erase the flash, that means there is a connectivity issue.
Hope this helps.
Q: How I can install IOS into cisco switch 3560 series?
In my cisco switch 3560 series hasn't IOS system and I cann't into priveleged EXEC mode. "enable" function cann't run!
A: The first thing you need to do is recover the password so you can "enable" privileged mode - you need to "break" as the switch is about to load…
1/ Put the new IOS onto a tftp server (if you don't have one, google for "tftp server free download").
2/ Get the switch onto the same network as your tftp server.
3/ decide if you have enough room in either flash or RAM (depending on your switch) and
copy tftp flash

Many electronic stars promote their tablets one after the other while iPad is sweeping over the world, such as Samsung’s Galaxy Tab, Lenovo’s LePad, Acer’s Iconia Tab and so forth. To follow this fashion and share market with other competitors, CISCO also announced that it would bring Cisco’s Cius Android tablet to AT&T in the following fall. Cisco Cius, Android-based, business-aimed, is a “mobile collaboration tablet that delivers virtual desktop integration with anywhere, anytime access to the full range of Cisco collaboration and communication applications, including HD video.”(John Chambers, Cisco CEO)
Also to aim at business sect, the Cius doesn’t appear to be a consumer product. It’s compatible with Cisco’s suite of business software tools, and designed to be able to connect mobile employees with the right people and right content from within the network. To our surprise, CISCO’s Cius is fully interoperable with telepresence tools, offers HD video streaming, multi-party conferencing, email, messaging, browsing and the ability to produce, edit and share content stored either locally or on the cloud.
And it features a front-mounted 720p HD camera that refreshes at up to 30 frames per second; Wi-Fi-enabled, comes with an accelerometer, has a detachable battery and a 5-megapixel rear-facing camera.
Cisco first unveiled the Cius tablet last summer. At the time, the company said the device would sell for less than $1,000. However, Cisco has yet to reveal pricing for the tablet. AT&T also failed to say how much it will charge for access to its HSPA+ network from the device.
Now, AT&T announced that it will sell CISCO’s Cius to enterprise users this fall. Cisco is shifting away from the consumer market. Besides the business-focused tablet---th Cius, the typical example is that Cisco killed off Flip video camera business and refocused its operation on core routing (all types of Cisco enterprise-based routers: Cisco1800/1900/2800/2900 series, etc., switching (Cisco switch catalyst 2960/3560/3750, 4500 series, etc.) and services, collaboration, architectures, and video.
No matter what difficulties Cisco need to face, we still believe that Cisco is a leader in networking solution, services for enterprises.
What Cisco brings to us next like surprising Cius? We are looking forward to it.
Recently, when you open internet to search news related to Cisco, title keywords like reorganize, recover, return, regain and refocus are common seen among Cisco news. Owing to increasing competitors such as Netgear, Juniper, Huawei, etc. all these have their own advantages, and share certain market with Cisco. So for Cisco’s part, there is a very fierce competition between itself and others. Moreover, there are many facts that show Cisco facing a big challenge, for example, Cisco has lost share in recent years in routers, and shut down its Flip video camera division in order to refocus on its core capability of router and switch.
Deciding to share enterprise market with Cisco, Huawei, Technologies Co., China’s largest telephone-network equipment maker, is expanding beyond its traditional business of supplying equipment for phone networks as it strives to more than triple sales to $100 billion in the next 10 years. The push to win more orders from businesses and government agencies may pose its biggest threat to Cisco. And Cisco now is actively searching for partners to enhance its competitive power, such as cooperating with Xerox to offer print services via the cloud through Cisco’s data center technology. HP, another challenger for Cisco, has introduced products supporting a new architecture namely FlexNetwork, which is directly targeting the Cisco's Borderless Networks strategy.
Meanwhile, Cisco also pays attention to their inner management to improve its efficiency while solving problems. Although Cisco has lost its Flip focus, faced more competition, it still has big predominance in routers, switches and service for business and enterprise. Cisco still retains 70% or so of the total switch market. And enterprise and business are Cisco’s main target market.
As we known, Cisco owns many types of routers and switches aim at providing the most professional service for small to large enterprise, such as popular series Cisco 1800 series, 1900 series, new items like Cisco 2911; Cisco switches series like switches 2960, 3560 series…
Frankly, even though Cisco faces many challenges from its counterpart, its core service is still competitive. Of cause, refocusing on its core, concentrate business and enterprise, all these actions can help Cisco keep a good condition among international market.
Which of the following is a reason why IPv6 has been developed?
a. IPv4 addresses are not secure. / b. IPv4 addresses are running out. / c. Dynamic address allocation is desired. / d. Mobile IP networking is needed.
What version of IOS do I need to run on a Cisco 3550 and 3560 to support IPv6?
Which routers are IPv6 enabled? Can anybody suggest me any IPv6 enabled routers?
Have you ever come to similar problems? With more netizen and faster development of internet, mobile internet, more and more people require a better enjoyment of surfing on the net and a higher internet security, we usually like to compare IPv4 with IPv6, often ask others that what IPv6 will bring to us?...
IPv6, a version of the Internet Protocol (IP), is designed to succeed Internet Protocol version 4 (IPv4). The Internet's growth has created a need for more addresses than IPv4 is capable of. IPv6 allows for vastly more numerical addresses, but switching from IPv4 to IPv6 may be a difficult process.
Comparison to IPv4
Pv6 specifies a new packet format, designed to minimize packet header processing by routers.
Advantages comparing to IPv4
Larger address space: The most important feature of IPv6 is a much larger address space than in IPv4. The length of an IPv6 address is 128 bits, but 32 bits in IPv4.
Multicasting: Multicasting (the transmission of a packet to multiple destinations in a single send operation) is part of the base specification in IPv6. In IPv4 this is an optional although commonly implemented feature.
Stateless address auto configuration (SLAAC): The packet header in IPv6 is simpler than that used in IPv4. IPv6 routers do not perform fragmentation…
Mobility: IPv6 routers may also support network mobility which allows entire subnets to move to a new router connection point without renumbering.
More advantages…such as options extensibility, jumbo grams.
Speak of cloud computing, we quickly think of our internet and the coming trend---the mobile internet. Right, cloud computing technology will change the future of internet. It owns the magical power of enabling users of "the cloud" can share computer functions by connecting, via the Internet or direct connection, to a specialized data center that holds all the data and programs necessary for their needs.
Cloud computing comes into focus only when you think about what IT always needs: a way to increase capacity or add capabilities on the fly without investing in new infrastructure, training new personnel, or licensing new software. Cloud computing encompasses any subscription-based or pay-per-use service that, in real time over the Internet, extends IT's existing capabilities.
Today, we all are looking forward to fantastic experience got from internet, because we can read and share almost all the topics related to our life, such as music, movie, shopping, technology, science, literature, entertainment, military, politic, etc. So what cloud computing really means to the future of mobile internet? We are really ready to engage in this topic.
Indeed, the fact is that we require better and more comprehensive service brought by internet, for example, with the smart phones, laptops, iPad and iPhones becoming more and more popular among consumers, they gradually like to share interesting things and hot topics anytime, anywhere. And it’s very possible to achieve it as the cloud computing technology and mobile internet develop fast.
Mobile internet, connecting to cloud computing technology, brings a new way of sharing personal experience with others, for mobile internet is an open world to allow internet users to download, upload and browse information as you like. Many telecom and networking giants like Google, Cisco, HP, IBM, Microsoft, etc. pay more attention to cloud computing technology’s application on their telecommunication and networking equipment, take Cisco as a typical example, Cisco helps organizations build, deploy, and use highly secure cloud services by providing essential infrastructure (to help customers build clouds, including networking, security, data center and unified computing solutions, systems management, and modular cloud elements.), new innovations (that broaden the reach and accelerate the use of clouds such as Cius, Cisco TelePresence, and IP phones.)…. Cisco works with a broad ecosystem of partners to help you realize the value delivered by cloud computing and accelerate business growth.
What can lead a new fad in the mobile internet world? Definitely, more magic will emerge in the future of mobile internet with wider cloud computing technology application.
Ren Zhengfei, the founder of Huawei, announced that they are confident of exceeding Cisco and Google in the future.
Over the past 23 years, Huawei has developed fast and achieved many great targets as a world-leading telecom solutions provider. It shares a certain market with Cisco and other competitors. Now, as the cloud computing bringing a great revolution in IT industry, Huawei puts aside its mystery and try to promote itself. Indeed, the policy of more communicating with public, media may help Huawei better improve its image as a leader in telecom industry. Cisco VS Huawei VS Google, who will take the first place in the IT field? It’s hard to say, because everyone has its own advantages.
Recently, Cisco also announced that it quit on the Flip to enhance its strongs of telecom solution. It’s obvious that the main competitors among telecom industry try to put most effort on researching more advanced solution to mobile net as the IT industry develop so fast.
Although other competitors such as Huawei, Juniper, Aruba, HP, etc. shared a certain market with Cisco around the world, Cisco’s always sticking to its strong points including supplying networking solution to medium and large enterprises. Cisco’s technology of safety, diversity, meets the medium-to-large sized business’ need.
Nowadays, as the cloud computing technology springs up and mobile telecommunication grows fast, telecom equipment manufacturers including Cisco, Huawei, HP, Microsoft, Brocade, etc. try to adjust its market and technology policies to help themselves better survive in market.
For routers, switches and computers becoming increasingly central to the digitalization of all kinds of industries, so no matter what policy Cisco, Juniper or Huawei takes, they can balance their market in the different aspects. Huawei PK Cisco, no winner, maybe cooperator.
Notes:Cisco, as the world’s leading telecom equipment designer and manufacturer, it owns many famous networking products among consumers, such as family, SOHO, small business, medium and large enterprises. Follow here to see hot Cisco products…
Today when I open ‘google search’, its ico has been changed into a picture of nature containing rill, waterfall, tree, lake, animals, etc. , the beautiful scene attract us and also remind us of protecting our living environment as well as increasing natural disasters, such as earthquake, tsunami, flood, drought… all of these warn human beings that we need live friendly with world.
Owing to fast social development, it’s obvious that process of urbanization becomes faster and faster, the distance among people is becoming closer and closer. Besides more modern buildings and heavy traffic, another important factor that tightly connect country to city is telecommunication.
Speak of telecommunication, what things will come to you mind? Internet? Media? Or Mobile phones? Indeed, we are engaged in a mobile internet world, more things and problems we can solve through internet. So no matter what industry you take, it’s vital for you to finish work by internet, or other electronic communication, it’s very important for you to communicate with our society, out nature and our world friendly and harmoniously.
For the larger consumption of energy and more serious environmental challenges, actions to handle these may be not too far to everyone or industry. Take some examples, The Envision Charlotte initiative has set a goal of reducing energy use by up to 20 percent within its perimeter through greater education of citizens and use of information technology. BC Hydro in Vancouver just announced that it will roll out 1.8 million smart meters based on Itron’s OpenWay technology, powered by Cisco ( world’s top networking equipment designer, e.g. Cisco router, Cisco switch, have you ever used?), to enable a more efficient grid and foster the use of renewable energy. And the city of Incheon, Korea is building in sustainability from the ground up.
So with the effort of all the human beings, the world, which makes us closer with modern transportation and communication (such as internet, media, newspaper, magazine, etc.), is becoming more harmonious, more comfortable, closer, safer and smarter.
