Tragedy or Comedy, When Cisco Faces Juniper

June 24 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Today, for business, satisfying and attracting customers is indispensable. That’s because customer requires better service and multifunctional products. Yet to meet customer’s need poses challenges. And the competition between counterparts is fierce. Because my work is related to Cisco, so I’d like to take Cisco as an example to analyze Cisco and its competitor Juniper.





Cisco was founded in 1984 and quickly became dominant. In its acquisitions, it focused on integrating marketing functions, not integrating the technology that it acquired. Cisco’s approach is based on multiple hardware boxes. Each hardware box runs proprietary software, and a different chip. For customers that has created huge complexity.



Juniper founded in 1996, the first serious challenge to Cisco. Jim Duffy notes in Network World that with the growing importance of the Internet, venture capitalists and unhappy Cisco customers invested a start-up in order to build a better mousetrap, specifically for service providers. Juniper’s first year was nurtured with early investments from the AT&T, Ericsson, Lucent, Nortel, Siemens/New bridge Networks, 3Com and UUNET. IBM agreed to develop custom chips for Juniper’s Internet routers.


Network Router Showdown: Cisco vs. Juniper

By TechNewsWorld.com

Cisco does have competitors, especially in sectors that crave speed. For example, when service providers like MCI/WorldCom, Sprint or AT&T update their infrastructure, they increasingly are choosing to buy from Cisco rival Juniper Networks (Nasdaq: JNPR). In fact, Liscom said, 23 of the 25 major service providers now use Juniper routers.


Juniper routers increasingly are being used in the infrastructures of governments' and financial institutions' intranets. According to her, Juniper boxes are purpose-built to handle new services, such as VPNs (Virtual Private Networks) that are tunneled over existing IP networks.


By Tutorialsweb.com

Operationally, both Cisco and Juniper routers are based on different hardware and software concepts. Cisco routers use Cisco IOS and Juniper routers use JUNOS.


Applications wise, both Cisco and Juniper cater to similar market segments. However, both have some advantages in certain areas compared to the other. Cisco, being the first to enter the market, has better market penetration. One of the strong areas of Cisco is the low-end router market including remote-office, and branch-office connectivity solutions. Both Cisco and Juniper provide high-end router solutions that offer gigabit transfers and advanced security routing solutions.


Cisco vs. Juniper, Tragedy or Comedy

From the analysis above we know that in fact both Cisco and Juniper have its own advantages in the market. The research and targeted consumer are little different, they share different markets. No winner, just comedy.

Routers, To See Different Types of Routers

June 20 2011 , Written by ciscorouterswitch Published on #Cisco Routers

There are several types of routers you may hear of: wired router, wireless router.



More detailed classification: Internal router (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; Backbone router (BR): Interfaces to backbone; Autonomous system boundary router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails.


If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of router. Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go. Generally, Routers that we used can either be wired or wireless. 


A wired router will generally connect to your computer and computers or hardware through an Ethernet cable.  This happens with the use of output ports. And the only input port provided on a router will be used for the Internet. 


A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections.  You will know the router you are using is wireless if it comes with an antenna.  The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the router, provided they have password access.


Two Typical Routers We Usually Used


Commercial Router

If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router.  These routers are much more powerful than what you would purchase at your local electronics or computer store.  The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem.  Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN. (Cisco is a leading router manufacturer to aim to provide router and networking solution to small, medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town.  The commercial-grade router will be used to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other. The local area network may consist of one large office within a building. In that case, you could have multiple LANs connecting to the WAN through one or multiple routers.


Consumer Routers

If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store. Generally you will want a router that serves as a wireless access point (WAP). It should also be a network switch. The wireless access point (WAP) basically provides the wireless access that everyone wants. That wireless access can be both to the Internet and to other computers in the home or office. Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths. Some of the lower priced consumer routers will not have a very strong firewall. (Cisco Linksys E-series routers, powerful home routers, are welcomed by a lot of Cisco fans, more info of Cisco’ home product store you can visit Cisco’s official site: cisco.com).

Identifying What is Router, Switch and Hub

June 17 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Internet colors and changes the world by broadening our horizon and connecting people around the world together.


Referring to network, some networking devices and equipments you must know. These are router switch and hub, which are all computer networking devices that let you connect one or more computers to other computers, net to other nets. Each has two or more connectors called ports into which you plug in the cables to make the connection.


How are data transfer and the implementation of networking protocols made possible in this powerful network? It is made possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. It is made possible because of networking devices that regulate data traffic over the whole network, providing connectivity and control. The network design is based on the OSI (Open Systems Interconnection) model.


After getting the general knowledge of router, switch and hub, you may are confused with these three devices. If they are all networking equiments that act as mediators at various levels of this networking model. What is the difference among them? Let’s do that and check it out.


The first is router, which connect two or more computing networks together. It is a highly intelligent device with embedded software that are used to control the flow of data packets across diverse networks, and charged with the responsibility of controlling the inter network data traffic.


A switch is charged with the job of connecting smaller segments of a single network into a connected whole. They are extensively used in Ethernet local area networks.


The last one, hub, connecting various Ethernet devices to integrate them into a whole network segment. It is one of the most basic hardware devices that connect two or more Ethernet terminals in a network.


More features of router, switch and hub

Router: Functional on the network layer of the OSI model, and it is also known as level 3. They integrate logical subnet together and their operation is made possible by inbuilt operating systems. They are designed to calculate the best possible path for transmission of data packets between networks. The basis for routing of data through a router is the use of Internet protocol addresses.


Switch is functional on the layer 2 of the OSI model. This layer is often referred to as the data link layer. Network switches transfer data across a network segment using MAC addresses for reference.


A hub operates only at layer 1 level of OSI model, which is the physical layer. Integrating Ethernet terminals together is its only function and it is a passive device used for data transfer.


Among these three networking devices, hub is gradually less used, and the most popular today is router. How much you get from this analysis?


If you need a router or switch, the following table of comparison between router and switch make you clearer.





More expensive than hubs or switches

Costlier than hubs


Cisco, Juniper Networks, Belkin, Extreme Networks, Huawei, Netgear

Cisco, Sun Systems, Oracle, Belkin, Linksys, and Net Gear, Huawei


Routers connect two or more logical subnets, which do not necessarily map 1-1 to the physical interfaces of the router.

Network switches inspect data packets as they are received, determining the source and destination device of that packet, and forwarding it appropriately


A router is a piece of hardware tailored to the tasks of routing and forwarding information. Routers generally contain a specialized operating system, RAM, NVRAM, flash memory, and one or more processors, as well as two or more network interfaces.

A way of routing electricity and data flow patterns through circuits based on binary decisions

Technical Specifications:

Routers operate at Layer 3 (Network) of the OSI model.

Network switches operate at layer two (Data Link Layer) of the OSI model.

Rate of Collision:


Switch having a connection that can carry both transmitted and received signals at the same time that we know this as a full-duplex communications. This will reduce or minimizes the possibility of collisions.

Less or More? Cisco Restructures Its Consumer Market

June 16 2011 , Written by ciscorouterswitch Published on #Cisco Routers

It’s not a secret for all that Cisco is restructuring its consumer market, including giving up flip video camera business, bracing for its biggest layoffs, refocusing on Cisco’s core networking, integratng Cisco umi into the company's Business TelePresence product line, assessing core video technology integration of Cisco's Eos media solutions business….



Also Cisco claimed that it would exit aspects of its consumer businesses and realign the remaining consumer business to support four of its five key company priorities – core routing, switching and services; collaboration; architectures; and video. As to this innovative and constructive programs, John Chambers, Cisco chairman and CEO, explains that Cisco‘s key, targeted moves in support of its network-centric platform strategy will help Cisco and its service provider customers optimize and expand their offerings for consumers, and help ensure the network's ability to deliver on those offerings.


Well, more benefits or more disadvantages Cisco refocus on its core technology, which means that it will provide better networking solutions and services for its target enterprises, have more potential partners to realize its projects. Just like losing weight, Cisco is cut down its consumer business that seems not bring better profits and improve its core technology. So for this aspect, it’s not bad news for Cisco and enterprise. And for personal consumer, although it cannot enjoy the further surprise by upgrading flip video camera, they also can get more advantages from networking innovation.


Who will benefit more or more disbennifit? Less or more? It depends on whether those restructuring measures become effective or bring practical effects? Let’s looking forward to it!

Cisco’s ASR 9000, Designed for the Zettabyte Era

June 9 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News



CISCO-ASR-9000.jpgCisco is never giving up innovation, so it is always upgrading its core technology to bring more professional networking solutions and better network services to our CISCO users and enterprise. Recently, exactly, June, 2011, to help service providers meet the rising tide of traffic generated and to help businesses make the transition to IPv6, Cisco’s newly released Visual Networking Index Forecast (VNI) marks the beginning of what the company calls the "Zettabyte Era," and its new ASR 9000 Series aggregation-services routers.


The new Cisco ASR 9000 system consists of the new Cisco ASR 9922 Router and high-density 10G and 100G interfaces for the network edge and the Cisco ASR 9000v for the network aggregation layer, as well as the existing Cisco ASR 9010 and Cisco ASR 9006 Routers.


Cisco on June 7 also introduced a new innovation called nV (network virtualization) technology, which was created to make network management easier and grow capacity by collapsing the network edge, aggregation and access layers into a single ASR 9000 system.


According to Cisco officials, the new ASR 9000 system combined with the nV technology offers 36 times the capacity of other competing products at 96 terabits per second. With such capacity, users could stream recordings of all Super Bowls, World Cup and Cricket World Cup matches in less than a second, or download 180,000 DVDs every minute, the vendor said.


The combination also means operating cost savings of up to 70 percent compared with competing edge platforms, simplified IPv6 transition and support for Cisco’s Videoscape technology.


More Facts about the ASR 9000 system:

Network simplification and savings are achieved through plug-and-play capabilities, singular point-of-service management using Cisco Prime for Internet Protocol Next-Generation Network (IP NGN), cost-effective configurations and ease-of-deployment features. This capability is available to the more than 500 existing Cisco ASR 9000 customers via an upgrade.

Cisco Videoscape technology is supported with the Cisco Integrated Service Module for caching, streaming and monitoring to optimize and monetize the video experience.


From Official Cisco

The Cisco ASR 9000 Series can be positioned for the following applications:

Residential any-play services, including cable, DSL, Passive Optical Network (PON), and Ethernet to the X (ETTx)

Business Layer 2 VPN and Layer 3 VPN services

Mobile aggregation

Video service-delivery networks



According to Cisco, the ASR 9000v product is available now, with the ASR 9922 becoming available early next year. But existing customers won’t have to deploy all new gear to take advantage of Cisco’s new virtualization technology. Cisco says the 500 operators who have already bought ASR 9000 gear will be able to introduce the intelligence with a simple upgrade.


The company already has several customers for the technology, including China Telecom, Cox Communications, Comcast and FastWeb. Verizon Wireless also uses Cisco's ASR 9000 routers.

Should Cisco Merge with Dell?

June 1 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

Cisco.jpegCisco has unleashed a world of hurt on its shareholders, masquerading as a consumer company that sells Flip phones, Umi telepresence, and Linksys routers. There's nothing wrong with selling gadgets to consumers. Apple does it brilliantly, and profitably. But Cisco isn't Apple.


In a sense, Apple might be a place where Cisco can find comfort in its time of trouble. People forget how screwed up Apple was in the 90s. The fact that Apple turned it around can provide a ray of hope to Cisco shareholders and the company's beleaguered CEO, John Chambers. If Chambers can keep his job.


Server and PC marker Dell has also had its share of problems in recent years – accounting scandals, poor sales execution, and exploding products – but of late, it has been on the upswing. It has had some success building custom servers for hyper scale data centers. It bought its way into the storage racket proper instead of just reselling other companies' kit (LSI and EMC, mainly). And it moved into services with its Perot Systems acquisition.


The rub is that Dell's Dell.jpegnetworking business is no more real than its storage business used to be. It is merely rebranding kit from Brocade and others. Until Dell fixes that, it will not be a credible infrastructure stack player.


Meanwhile, Cisco has done a remarkable job building a server business out of nothing with its "California" Unified Computing System blade and rack servers – and with a fair amount of actual engineering – but it is not a profitable volume manufacturer any more than IBM was. Big Blue couldn't cut it in printers, memory, disk drives, and PCs, and Cisco is having trouble with anything other than core switches and routers.


One could argue that Cisco should not have entered the server market at all, but that is an over-simplified view. No doubt, the move into servers has not only annoyed Cisco's former partners in the server business, but compelled them to start selling their own networking products, either rebadged (from Brocade, Juniper, or Blade Network Technologies) or built with the help of ODMs (Sun and now Oracle does this, and so does Dell).


More about Cisco Switching Business

What is hurting Cisco's switching business? Mellanox, Juniper, Brocade, Extreme Networks, Arista Networks, and IBM can make faster and lower-cost top-of-rack switches, and there are cheaper alternatives to Cisco's end-of-row plain-vanilla Catalyst 6000 and converged Nexus 7000 switches.


Chambers (Cisco’s CEO) may believe that the price/performance of the Nexus 7000 compared to earlier Catalyst products is what is driving Cisco's switching biz down. But it is probably more accurate to say that Cisco's prices are too high relative to the competition.


Even though competitors shared a certain market, Cisco is still proud of its core offer and service. Every CISCO user knows that what Cisco attract him to choose it.Dell and Cisco-copy-1


Related: Cisco owns a large number of popular Cisco switches among enterprise users. To serve enterprise better, Cisco instantly improve its service and networking solution. Now, let’s check some star Cisco switches: Cisco 2960, Cisco 3560, Cisco 3750, and Cisco 4500…which type you prefer to?

Cisco Allies with Xerox on Managed Print, Outsourced Cloud Services

May 31 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

As buddies, CISCO and Xerox will ally to bring more managed print services, mobile print services and cloud IT outsourcing to solution providers, particularly to Cisco partners who haven’t delved into managed print arena, said executives.


“Xerox and Cisco think networking and print managed services are a great combination. They’re like peanut butter and jelly,” said Rick Dastin, president of Xerox Enterprise Business Group. “And it tastes good too.”


The solutions CISCO and Xerox offered will benefit customers as the list below.

A. Xerox Managed Print Services (MPS) over Cisco Borderless Networks: The partners mean to consolidate IT and print management using the network's embedded security, WAN optimization and Internetwork Operating System (IOS) software. It will monitor print technology and supposedly reduce operating costs, protect confidential data from any location, and improve employee productivity with advanced mobile and cloud printing applications.


B. Xerox Cloud ITO Services built on Cisco's UCS and Vblock infrastructure: It will accelerate customer rollout of new IT services, so they can respond better to changing needs of the workforce and reduce IT costs through a private, public or hybrid cloud environment. These infrastructure-as-a-service and cloud consulting services as well as private cloud deployments will come from ACS, a Xerox company.


C. Xerox Mobile Print Solution on Cisco virtual desktop clients and its Cius tablet: Mobile workers will be able to print from any e-mail-enabled device including Cisco's virtual desktops clients and Cius tablets to any enabled printer using Cisco Borderless Networks and Wireless LAN solutions from any location.      


As we known, Cisco has many partners, such as famous Dell and Microsoft; they also have some items to be buddies. What surprise will Cisco bring to Cisco users and customers; we are looking forward to it.


Related: Cisco’s core market is Cisco routers and Cisco switches for small to large enterprises. If you would like to know about Cisco routers or Cisco switches like purchasing, price, types and routers’ features you can visit Cisco.com or routerswitch.com to see more…

After Salesforce.com, Cisco is the Second Popular Company in Silicon Valley

May 25 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

NetBase Solutions, a SOCIAL MEDIA ANALYTICAL COMPANY, delivered a report recently, showing that Cisco is more popular than other Silicon Valley enterprises, just followed the Salesforce.com.



This report may make Cisco confident of recovering from difficulties while Cisco is surrounded by bad news for its terrible performance.


Why did Cisco can regain too much applause from social networks? From what customers really care about; maybe we can get the answer. Even though Cisco shut down flip video camera business, will eliminate up to 4000 jobs in the near future, didn’t get support from investors, it is still a minion in social Medias. More important is that most Cisco users are satisfied with its network equipment, especially routers, switches and firewall security for family and enterprises.


Actually, Cisco and Salesforce.com have been partners for several years, working together to help you join online conversations about your company and take control of the customer experience in Web channels outside your company’s domain. The typical project between Cisco and Salesforce.com is to combine Salesforce.com's Service Cloud 2 and Cisco's Unified Communications to deliver a complete cloud computing solution for customer service. The solution empowers small and medium sized companies to run their customer service completely in the cloud. They share a vision about moving technology into the cloud and leveraging social networking sites like Facebook, Twitter and Google to deliver services to their customers where they are already collaborating.


Because of increasing popularity of talking and sharing anything with each other on internet, more and more enterprises and groups are willing to make full use of the social media service to enlarge their business, intensify market competition to meet challenges from counterparts and other related markets.


Although Cisco faces a big challenge from consumer market as well as enterprise market, it still keeps its own superiority, providing high quality Cisco routers and switches for SOHO, small, medium and large enterprises, better services for consumers. Now Cisco is actively learning how to innovate faster and delight its clients through a radically different approach to management, which will make its prospects bright.

Cisco IOS, How Much You Know About Cisco IOS?

May 19 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News


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:

configure terminal

interface vlan 1

ip address w.x.y.z

no shut


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.

Source(s): http://www.cisco.com/en/US/products/hw/switches/ps700


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


Cisco IOS Download Tips

Generally, if you want to download or upgrade Cisco IOS while having a used Cisco router or didn’t buy Cisco router, options offered here will help you get the Cisco IOS:

1.       Download the Cisco IOS from somewhere like a bit torrent or a file sharing program.

2.       Purchase a maintenance contract for the hardware and download the software.

3.       Buy the IOS from a reseller. (The cost of the software will vary based on the model of the router you are buying it for and the features of the OS you are wanting.)
