Reorganize, Refocus, Can Cisco Recover with Confidence?

May 11 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

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.

 recover-with-confidence1.jpeg

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.

Why We Need IPv6? IPv6 VS IPv4

May 6 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

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.

 ipv6-ipv4.jpeg

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.

Cloud Computing, A New Fad in the Mobile Internet’s Future

May 3 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

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.

cloud6

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…

Friendly Environment, Harmonious Communication Required

April 22 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

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.

 62914aabtw1dg1z94fvmmj.jpg

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.

Router? Switch? Be Clear the Difference Between Router and Switch.

April 11 2011 , Written by ciscorouterswitch Published on #Cisco Routers

When someone talk about Cisco router, or Cisco switch with me, I’m very confused about this. Router? Switch? What are they? What are they used for? Oh, My Lady Gaga, complicated.

 

However, after I have found some details of router and switch, it seems a little interesting. Because both router and switch are tightly related to network, to internet. If you have PCs, if you need to email to somebody, or if you want to chat with friends, they are necessarily contained. Haha, eager to get more information of router and switch. I search many details and “the difference between router and switch” through Google. Now, I’d like share some key info about router and switch.

router-vs-hub-vs-switch.jpg

 

What’s a router? A router is a more sophisticated network device than either a switch or a hub. It is a device that forwards data packets across computer networks, and perform the data "traffic directing" functions on the Internet. On the Internet or on a large corporate network, for example, routers serve as intermediate destinations for network traffic. These routers receive TCP/IP packets, look inside each packet to identify the source and target IP addresses, then forward these packets as needed to ensure the data reaches its final destination. Routers for home networks (often called broadband routers) also can join multiple networks. These routers are designed specifically to join the home (LAN) to the Internet (WAN) for the purpose of Internet connection sharing. In contrast, neither hubs nor switches are capable of joining multiple networks or sharing an Internet connection.

 

And switch? A network switch or switching hub is a computer networking device that connects network segments. The term commonly refers to a multi-port network bridge that processes and routes data at the data link layer (layer 2) of the OSI model. By paying attention to the traffic that comes across it, it can "learn" where particular addresses are. For example, if it sees traffic from machine A coming in on port 2, it now knows that machine A is connected to that port and that traffic to machine A needs to only be sent to that port and not any of the others.

 

The two pieces of equipment (router and switch) look so similar and perform some similar functions, but each has its own distinct function to perform on a network. To be simple, switches create a network. Routers connect networks. A router links computers to the Internet, so users can share the connection. A router acts as a dispatcher, choosing the best path for information to travel so it's received quickly.

 

So what do you need? A router or switch? After got these above, you can make sure that which you need. And more information of Cisco sale, you can visit RouterSwitch.com

How to Configure Cisco ASA 5505?

April 8 2011 , Written by ciscorouterswitch Published on #Cisco Routers

The Cisco ASA 5505 Firewall is the smallest model in the new 5500 Cisco series of hardware appliances. Although this model is suitable for small businesses, branch offices or even home use, its firewall security capabilities are the same as the biggest models like 5510, 5520, 5540, etc.

 

The Adaptive Security technology of the ASA firewalls offers solid and reliable firewall protection, advanced application aware security, denial of service attack protection and much more. Moreover, the performance of the ASA 5505 appliance supports 150Mbps firewall throughput and 4000 firewall connections per second, which is more than enough for small networks.

 

The difference of the 5505 model from the bigger ASA models is that it has an 8-port 10/100 switch which acts as Layer 2 only. That is, you cannot configure the physical ports as Layer 3 ports, rather you have to create interface VlANs and assign the Layer 2 interfaces in each VLAN.

 

By default, interface Ethernet0/0 is assigned to VLAN 2 and its the outside interface (the one which connects to the Internet), and the other 7 interfaces (Ethernet0/1 to 0/7) are assigned by default to VLAN 1 and are used for connecting to the internal network.

 

Basic Steps to Configure Cisco ASA 5505:

Step1: Configure the internal interface vlan

ASA5505 (config)# interface Vlan 1

ASA5505 (config-if)# nameif inside

ASA5505 (config-if)# security-level 100

ASA5505 (config-if)# ip address 192.168.1.1 255.255.255.0

ASA5505 (config-if)# no shut

 

Step 2: Configure the external interface vlan (connected to Internet)

ASA5505 (config)# interface Vlan 2

ASA5505 (config-if)# nameif outside

ASA5505 (config-if)# security-level 0

ASA5505 (config-if)# ip address 200.200.200.1 255.255.255.0

ASA5505 (config-if)# no shut

 

Step 3: Assign Ethernet 0/0 to Vlan 2

ASA5505 (config)# interface Ethernet0/0

ASA5505 (config-if)# switchport access vlan 2

ASA5505 (config-if)# no shut

 

Step 4: Enable the rest interfaces with no shut

ASA5505 (config)# interface Ethernet0/1

ASA5505 (config-if)# no shut

Do the same for Ethernet0/1 to 0/7.

 

Step 5: Configure PAT on the outside interface

ASA5505 (config)# global (outside) 1 interface

ASA5505 (config)# nat (inside) 1 0.0.0.0 0.0.0.0

 

PS: PDATE for ASA Version 8.3

From March 2010, Cisco announced the new Cisco ASA software version 8.3. This version introduced several important configuration changes, especially on the NAT/PAT mechanism. The “global” command is no longer supported. NAT (static and dynamic) and PAT are configured under network objects. The PAT configuration below is for ASA 8.3 and later:

object network obj_any

subnet 0.0.0.0 0.0.0.0

nat (inside, outside) dynamic interface

 

Step 6: Configure default route towards the ISP (assume default gateway is 200.200.200.2)

ASA5505 (config)# route outside 0.0.0.0 0.0.0.0 200.200.200.2 1

The above steps are the absolutely necessary steps you need to configure for making the appliance operational. Of course there are much more configuration details that you need to implement in order to enhance the security and functionality of your appliance, such as Access Control Lists, Static NAT, DHCP, DMZ zones, authentication etc.

Cisco Notes:

Cisco ASA 5500 Series: Stop security attacks before they affect business continuity. Cisco ASA 5500 Series Adaptive Security Appliances provide intelligent threat defense and highly secure communications services. These solutions help organizations lower their deployment and operational costs while delivering comprehensive network security for networks of all sizes

A Date with Video Chat’s Time

April 7 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Zoya Fallah shared her fantastic experience of Her first Cisco ūmi Call With her dad with Cisco readers and friends, details from her description: “Recently, my dad bought me a Cisco ūmi Home TelePresence system so we could keep in touch face to face. I must say, being able to see him in my living room whenever I want is fantastic. Our first call was ideal, because his cousin Ruthie happened to be visiting from Ohio. I’d never met her before (although she says we met when I was a baby). It was so cool to “meet” her in person, and put a face to the name I’d heard for so long. It really was like being there.” In some ways, it indicates a new level of video chat.

112.jpg

 

Nowadays, with the development of Information Technology, video call, video chat, and video conferencing have been built around us and our connecting world. Video has lost its mystery since we can carried a device mobile phone, digital camera or camcorder, iPhone, iPad or Flip capable of recording video. What’s more, in an age of YouTube and Facebook, people can share their favorite experience and story with people who come from all over the world.

 

Today a typical home broadband connection can easily handle full-screen standard definition video and a good one can do HD. In addition, nearly all laptops feature built-in cameras. Indeed, video chat and video call change our daily life.

 

Mobile devices, however, are still a challenge because of the challenges of moving quality video over wireless networks. So network manufacturer such as Cisco, Netgear, TP-LINK, Huawei, trying to find a best solution to improve people’s video chat and call. 3G, 4G, Wi-Fi, in some sense, achieved the situation on video chat.

 

It’s obvious that video calling and chat are becoming increasingly important. Achieving its full benefit is going to require continuing network improvement, especially in wireless. With the effort of network manufacturer, we hope that we can enjoy the convenience that brought from Information Technology.

 

Cisco Notes: Besides Cisco’s new ūmi Home TelePresence system, Cisco supplies different types of Cisco IP Phones VoiP to business and clients. More info about Cisco IP Phones VOIP series you can visit RouterSwitch.com to see.
