The majority of Cisco routers run Cisco IOS Software with the command-line interface (CLI). The CLI is used to interface with the device and send commands to the device. This is achieved through the use of a terminal, a terminal emulator, or a Telnet connection. Some routing cards, such as the Multilayer Switch Feature Card (MSFC) daughter card for the Catalyst 6000 series LAN switches, also run Cisco IOS Software.

feed How A Cisco Network Engineer Can Shape The World
January 15th, 2010
feed When asked what you wanted to be when you grew up, you probably didn’t say a Cisco network engineer. In fact, unless you had a computer geek or an engineer in your family, you probably didn’t say an engineer at all. Kids usually want to be things that they see as glamorous models of people who change their world: firefighters, athletes, and even teachers.
What to Know Before Upgrading Your Cisco Router
January 4th, 2010
feed Expanding the capacity of any high bandwidth network is always an involved process. The actual cost of upgrade hardware and the task of physically installing RAM memory into your Cisco routers’ expansion slots is simple enough, but most high-capacity data networks serve production environments which demand fault-tolerance and as near to total uptime as possible. In order to build a network that can be relied upon to guarantee this level of service, network engineers need to plan a long way ahead. In addition to ensuring the servers, workstations, cabling and software can handle increasing loads for years to come, when planning a new segment, a good engineer will consider the possible lifetime cost and load of each and every crucial device on the network. This includes Cisco routers! As it may be difficult to even temporarily disconnect a mission-critical router to upgrade its memory, one way to “future proof” your network is to upgrade the device at purchase – prior to installation. This may sound expensive, but in any truly high-bandwidth medium, the cost of downtime or loss of connectivity far outweighs the safe option of upgrading your routers memory to the maximum before installing it. If you do indeed decide to take the path of pre-upgrading a Cisco router for life, you will be choosing to save yourself from ever having to take it out of commission in order to install new Cisco DRAM memory or flash. Though the cost may be significant, not upgrading presents even more significant risks. It’s well known that a router is more likely to fail if it is run with insufficient RAM for it to cope with its workload. This raises the question of Cisco memory will be enough over the lifetime of a given product. Unfortunately, there’s no simple answer to this question: How much RAM a Cisco router is going to need changes depending on the enterprise and its scale, what sort of applications your network is (and will be) supporting, and of course, which series router you’re using. Cisco makes some forecasts and recommendations available to customers to assist in making this judgment. Generally, upgrading to the maximum memory your router is capable of supporting takes some of the guesswork out of this equation. The Cisco memory requirements for each are made available in individual the product specifications, and Cisco lists which product lines will be supported at least 18 months in advance. In this way, a diligent network analyst may make fairly accurate predictions of what their individual requirements will be for at least the next couple of years, and likely, much longer. After checking the installation procedure and maximum upgrade capacity for your particular Cisco router, you have two options, either purchasing the memory directly from Cisco at a considerable markup, or from a memory reseller such as PC Wholesale. Memory resellers offer a tremendous advantage over purchasing directly from Cisco for the budget conscious company – many times their prices can be up to 90% off Cisco’s list price, for the same exact memory!
Stretch the Business Budget with Used Cisco Equipment
December 16th, 2009
feed As the economy staggers through the recession, the cost of doing business has increased dramatically. This has encouraged businesses to investigate various ways to cut costs and stretch their budgets without cutting personnel. IT departments are often the hardest hit and are forced to make due with what they have, or purchase sub-par equipment, by industry standards, in order to meet budgets. Although Cisco routers set the benchmark for network platforms, out of the box they can be too expensive for fledgling or struggling businesses to pocket. In this adverse market, IT equipment has evolved to meet restricted demand, and deploying refurbished Cisco equipment becomes a more attractive option. Cisco switches are components typically coupled with the routers within the Cisco network. Ideally, most companies would prefer to purchase this IT equipment new, but in leu of the burgeoning economic situation it is not always the most viable alternative. Many businesses are now opting to employ refurbished, or used Cisco routers and switches. It also has become a common practice to deploy used Cisco IT equipment, as evidenced by the emergence of reliable vendors specializing in refurbished and re-marketed Cisco equipment. This serves as a testament to both the initial quality of Cisco routers in addition to the overall reliability of a used Cisco router. Regardless of rejuvenated demand, there are inherent risks to purchasing used Cisco equipment, mainly manifested by an overall fear of buying “used. ” The fear of premature or prescheduled failure permeates IT departments, despite that refurbished equipment is always tested to meet original manufacturer specifications. It is of vital importance to purchase used Cisco equipment through a reliable vendor. In order to choose the best vendor, it is necessary to consider the company’s reputation. Network Systems Resale specializes in selling both new and used Cisco equipment. Remarketed, gently used and surplus I. T. equipment is meticulously cleaned at their state-of-the-art testing facility in San Jose, California. The benefits of buying new are obvious, but vendors like Network Systems Resale offer adequate compensation in terms of warranties and customer service to make the purchase decision of used Cisco equipment less stressful. They provide a standard 90-day full replacement warranty on every purchase with extended warranty options of up to 1-year. Companies that succeed in this market tend to build a reputation based on customer service. Network Systems Resale is known for selling quality products both new and used, in addition to only selling used Cisco equipment that has been tested and deemed worthy for deployment. Another benefit of choosing a reliable vendor is their availability and customer service, for which Network System Resale is well reputed in both. Reliable vendors, such as Resale, selling reliable refurbished IT equipment makes the decision to purchase significantly less risky. Currently, used IT equipment is a niche market. It is apparent that the niche for used IT equipment will mostly likely expand. As Cisco continues to set the industry standard for network platforms, the demand for used Cisco equipment will follow. Before you cut personnel, look to cut your costs ands stretch the budget with refurbished IT Cisco equipment. Typical apprehensions about purchasing a used Cisco router can be quelled by partnering with a reliable vendor, such as Network Systems Resale.
Cisco Offer New Line Linux Routers
December 9th, 2009
feed Cisco is a top vendor in the networking arena and are fairly ubiquitous in enterprise environments. With the acquisition of Linksys, Cisco was able to enter into the consumer market to provide routing and switching for home networks with a proven brand.
Now it is looking to get into the SMB space with a router based on Linux to provide high quality service in non-enterprise business environments. Cisco will be phasing out the Linksys brand in favor of products branded as Cisco Small Business and Cisco Small Business Pro. Looking at this from the SMB side of the table, I can definitely see the upside both for Cisco’s business and for network admins who previously haven’t been able to justify big enterprise equipment for their SMB, but who are naturally attracted to the well-known Cisco brand.
Cisco initially built a task force to research the SMB market about a year ago and has entered the market with the AP541N wireless access point. The device should be less complex to configure and maintain than other devices because of its Linux-based configuration rather than the Cisco IOS. Read more
