Cisco 871 Interfaces and Basic Configuration

July 30 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

It is obvious that Cisco is a computer networking giant around the world. It designs and manufactures routers, switches for both consumer and enterprise market.


The Cisco Router 800 series belongs to the lowest SOHO end. The most popular models in the 800 series are the 880 and 870 broadband access models which come with different types of WAN broadband interfaces. Cisco 871 routers are equipped with a 10/100 Ethernet WAN interface which means that your ISP should provide you with a broadband modem offering an Ethernet connection towards the customer.


Look at the following figure which shows the back panel of Cisco Router 871.



Ports FE0 up to FE3 under the LAN group can be used to connect internal computers or maybe to an internal switch to expand the number of internal ports (see points 1, 2 in the figure above). These ports are actually Layer 2 switch ports, and not regular Layer 3 router ports. They are assigned by default to VLAN 1. You can create more VLANs and assign each port to a different VLAN (870 series), thus creating extra segmentation for your internal LAN. You cannot configure IP addresses directly on the interface ports. The IP address must be configured on the Interface VLAN 1 and example below.

Port FE4 is the WAN interface which must be connected to the ISP DSL broadband modem (see point 3 in the figure above). This port is a normal Layer 3 router port, which means you can configure IP address directly on the interface port.


Default Configuration for 871 Routers

The Cisco 871 routers come with some preconfigured parameters (IP addresses etc.) which might be in conflict with your current network topology. What I suggest is to erase the factory’s default startup configuration before you begin configuring your router for the first time. This allows you to start with a clean state and configure the router with all the features you need and leave off any that you don’t want.


Connect with a console cable and after you get a command prompt execute the following:

Router> enable
Router# erase start


After you confirm the command, all the default configuration will be deleted. Power off the router device and then power on again.


You will get a prompt as below:

Would you like to enter the initial configuration dialog [yes/no?]

Type no and press Enter. This will give you a command prompt (Router>) and you are ready to configure your router from scratch.


Type show run to see the current configuration which looks like the following:

(Some output omitted)

Interface FastEthernet0
no IP address
interface FastEthernet1
no IP address
Interface Fast Ethernet2
no IP address
Interface FastEthernet3
no IP address
Interface FastEthernet4
no IP address
duplex auto
speed auto

Interface Vlan1
no IP address


Initial Interface Configuration

From the above output you can see that FE0 up to FE3 are shut down and also there are no IP addresses configured to any ports. You need first to enable FE0 to FE4 and then configure IP address under the “interface Vlan 1” and also under the “interface FastEthernet4” port. Notice that you cannot configure IP addresses under the “interface FastEthernet0″ up to “interface FastEthernet3″ ports. Those ports are Layer 2 switch ports and will inherit the IP address you assign under “interface Vlan1″.



Assume that the internal LAN has IP network range Also, our ISP has assigned us a static public IP address of . Let’s see the interface configuration below:

Router(config)# interface fastethernet 0
Router(config-int)# no shutdown
Router(config-int)# exit

Router(config)# interface fastethernet 1
Router(config-int)# no shutdown
Router(config-int)# exit

Router(config)# interface fastethernet 2
Router(config-int)# no shutdown
Router(config-int)# exit

Router(config)# interface fastethernet 3
Router(config-int)# no shutdown
Router(config-int)# exit

Router(config)# interface fastethernet 4
Router(config-int)# no shutdown
Router(config-int)# ip address
Router(config-int)# exit

Router(config)# interface vlan1
Router(config-int)# no shutdown
Router(config-int)# ip address
Router(config-int)# exit


Notice that we configured IP addresses only to fast Ethernet 4 and vlan1. By default, interfaces fast Ethernet 0 to 3 are assigned to VLAN1 so anything you connect to those interfaces (internal LAN hosts) will belong to vlan1 network range and they must have as default gateway the address


More Attentions

All the 800 series models come with a 4-port 10/100 managed switch used for connecting the internal LAN computers, and with an IOS software that supports security features including the Firewall set. The main difference of each model is the WAN interface. All models that end with “1” in the model number (i.e. 851, 861, 871, 881, 891) have a 10/100 Fast Ethernet interface as a WAN port. The other models have an xDSL type WAN port (i.e. ADSL, G.SHDL, and VDSL2). Also, all models have the option of a Wi-Fi Radio interface (the model number ends with a “W”, e.g. 851W, 857W, 861W etc.).

Best Reasons to Buy Used Cisco Hardware

July 29 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

For most businesses, Cisco network hardware is their top choice to improve networking performance, or to expand the network because of business growth. We know that Cisco is famous for providing its professional networking solutions and network equipment with high performance for small, midsized and large enterprises and head offices. But the problem is that brand new Cisco equipment is more expensive than others and used CISCO network hardware. In fact, used Cisco hardware is also considered by many businesses, for buying used cisco network products can save cost and it still keeps good condition and high performance.


Possible reasons why you choose used Cisco equipment:

Cost Savings, More Discount – Of course, it is obvious that refurbished Cisco equipment is going to be much cheaper than buying a new Cisco router or switch right off the assembly line. But the savings to an I.T. department can be considerable without sacrificing anything with regards to quality and reliability. A company can save up to 90% off of the original retail price for certain Cisco models.  If the equipment performs well and the performance is satisfactory, such lower-priced models of routers, switches, firewall security or Cisco memory can be a financial lifesaver. The savings can be so considerable that it may make sense to by replacement equipment to have on hand as insurance; when a network goes down, every minute of downtime can cost money.


Reliability – Most reputable used Cisco vendors perform refurbishment that restores the Cisco equipment to like new condition. In addition, the networking hardware is thoroughly tested, plus the entire process is backed by a quality-assurance system that is certified by a third party. A dealer that has an ISO-certified quality management process will help to ensure that the equipment you get will perform at its best and last a long time.


Service – The best used Cisco dealers offer unbeatable service; usually better than you can receive from most new equipment dealers. The equipment they sell should have an excellent warranty. And if anything should go wrong, they should be easy to reach and be sending out replacement equipment immediately. Also, top vendors should offer a next business day replacement program that will provide new equipment before the old equipment needs to be sent back. Speed is of the essence!


Another important point, that is if you are considering buying used Cisco network hardware, you should lookfor a reliable and reputable Cisco supplier. Often there are unscrupulous dealers who will sell you inferior or even counterfeit equipment. Be certain that the company you are dealing with offers top-quality Cisco networking equipment, that it has been in business for a long time, that it has testimonials and references you can check, and that it backs up the equipment with a bona fide warranty.

It's Time to Buy Cisco?

July 21 2011 , Written by ciscorouterswitch Published on #Cisco Technology - IT News

Last week, search engine giant, Google (GOOG) jumped 15% in one day.


About six weeks ago, I wrote a post stating that Google was undervalued by 33%, and worth buying at around $500 per share. Since then it’s jumped to $600, a whopping 20% jump, more if you managed to get in at the low point. Quite a strong move for a large cap stock.


I still think the story for Google is strong, but if I didn’t already own it, I wouldn’t necessarily buy it today. Instead, I’d look for another cheap stock, something a little more boring.


As I wrote about in a previous post on investing in boring stocks, I prefer unloved, boring stocks with no growth prospects over exciting, glamor stocks. Incidentally, the stock I mentioned in that post, Johnson & Johnson (JNJ), is up over 10% in the past four months.


One of the stocks I’d consider is Cisco (CSCO).


This tech giant has lost its luster, with the stock price having gone nowhere for the past ten years.


I blame the poor leadership of the CEO, John Chambers, for the stock's performance. But at today’s prices, it probably doesn’t matter how incompetent management is.


Cisco currently trades for $15.66 with a newly introduced dividend yield of 1.50%. It trades for a P/E of 12.2, but more importantly it trades for a P/FCF of only 9.2.


FCF or free-cash-flow is one of my favorite metrics when valuing stocks. It’s the cash left over after all the expenses have been paid out, and capital expenditures have been made. Unlike earnings, free-cash-flow is very hard to manipulate. Over the past decade, even though Cisco’s share price has stagnanted, the free-cash-flow has more than doubled from $4.1 billion to $9.2 billion.


For a stable, profitable market leader like Cisco, ten times free-cash-flow is a great deal. As Warren Buffett indicated in his purchase of Lubrizol, it’s okay to pay 20 times free-cash-flow for a great company.


Cisco also has an incredibly strong balance sheet, with about $40 billion in cash or $7.80 per share in cash – that’s almost half of its stock value.


Even though Cisco faces increasing competition and has a penchant for wasting money on acquisitions that don’t seem to make any sense, it still has a wide economic moat. Cisco makes devices that move internet traffic, and the amount of internet traffic is increasing every day.


It’s only a matter of time before Cisco becomes a $25 stock again.

Cisco Expands Wi-Fi Coverage for Fans in the Sports Stadium and Entertainment Venues

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

Cisco announced its Connected Stadium Wi-Fi initiative which includes an enhanced access point, improved antennas and services to further its leadership in networking and telecommunications.


Cisco Connected Stadium Wi-Fi provides high-capacity; blanket Wi-Fi coverage on a converged and customizable network for all persons in attendance at the event, including employees, back office and press operations. It is generally available in stadiums, arenas and other congested environments. Fans are demanding a new set of services and with this access to Wi-Fi you'll be able to see app providers and physical service providers deliver a new experience in live venues. Other uses of the technology include the ability for fans to watch video highlights, view stadium information and allows operators and venue owners the use of advertising on the network for additional revenue.


Core to the solution is Cisco’s first purpose-built access point, the Aironet 3500p, an evolution of the Aironet 3500 that was announced last year, and designed to meet the performance and aesthetic needs of high-density environments. This new access point optimizes performance through a high-density directional antenna and special configuration that allows precise focus of the wireless airwaves into a concentrated area. Each venue is different, and Cisco said that each system of access points will need to be tailored depending on the size and structure of the venue. Cisco retails each access point at $1,500 and said that a stadium which seats 50,000 fans would need around 350 access points for full coverage.


With the increase of fans using smartphones and tablets to share daily info, experience and work, the Wi-Fi Coverage in the Sports Stadium and Entertainment Venues is expanded, which is benefiting people who like to work or share things in public, such as Starbucks, bars, clubs, sports stadiums. And now Cisco Connected Stadium Wi-Fi is delivering rich and interactive experiences pervasively to fans anytime, anywhere.

Cisco’s Cius Tablet is Coming

July 4 2011 , Written by ciscorouterswitch Published on #Cisco Routers

Cisco Systems’ new Android-based Cius media tablet featuring enterprise-class security capabilities will go on sale July 31 at a street price of $750, according to Cisco’s announcement. The Cius seemed interesting enough when it has been first reported since one year ago. For Cisco Cius, it’s good to avoid going headlong against Apple's iPad in the consumer space.


"There is room out there for tablet vendors who can crack the enterprise space in niche areas that might actually prove both sizable and profitable," Hilwa (director of applications development software at IDC) said. "This requires a special enterprise sales capability and likely a vertically focused strategy that homes in on the value proposition of the device for the requirements of a specific industry scenario."


Referring to Cisco’s official elaboration as follows, we can get a general impression of Cisco Cius.



An ultra-portable, mobile collaboration enterprise tablet that offers access to essential business applications and technologies.



Preparing for a New Way of Working

Extends the power of participation to everyone, liberating users from the confines of geographic and organizational boundaries.

Delivers the enterprise-class mobility, security, and manageability required by IT organizations.

Fosters a new way of working with a new class of collaborative applications created by Cisco and our partners.


The First Collaborative Tablet Built for Business

Almost Anyone Can Benefit from Cisco Cius

Cisco Cius tablet delivers the same rich computing, communications, and collaboration experience in the office, around campus, and off-campus, so it can improve the productivity of virtually any worker.


With comprehensive collaborative capabilities, busy executives - whether they are in or out of the office - can make audio or video calls; create, edit, and share video; attend telepresence sessions; conference; IM; and send email messages.


With constant connectivity and real-time HD video, sales representatives can be responsive to customers and give impromptu presentations to prospects everywhere.

With transparent mobility and virtual computing, knowledge workers (based on their roles and preferences) can stop lugging around heavy laptops, and still be able to compute, communicate, and collaborate in conference rooms, corridors, and cafeterias.


With rich video collaboration, office-based administrative assistants can make communications more personal and more effective with the people they support.


With the ability to send and receive data and video anywhere, case workers can enter information when mobile, interact with colleagues all the time, and never have to return to their desks to access, update, or send files.


The Cisco Cius runs on Google's Android 2.2 and Intel's low-power Atom Z650 processor, spokesperson Molly Ford wrote in an e-mail. "The Intel Atom Z650 processor has strong video capabilities, including the ability to enable multi-point videoconferencing in specific use cases," Ford wrote. "The Atom Z650 processor can also decode video at a 1080p resolution and encode at a 720p resolution."


Why Cisco/Cisco Cius

Cisco Cius is part of a complete solution, which includes the:

Cisco Cius tablet
