How to Set Port Security on a Cisco Catalyst Switch?

October 28 2011 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

If you want to ensure that only a certain device—for example, a server—is plugged into a particular switch port, you can configure the MAC address of the server as a static entry associated with the switch port.Cisco-switches.jpg

 

Configure port security

Configuring the Port Security feature is relatively easy. In its simplest form, port security requires going to an already enabled switch port and entering the port-security Interface Mode command. Here’s an example:

Switch# config t

 

Switch(config)# int fa0/22

 

Switch(config-if)# switchport port-security ?

 

aging Port-security aging commands

mac-address Secure mac address

maximum Max secure addresses

violation Security violation mode

 

Switch(config-if)# switchport port-security

 

Switch(config-if)#^Z

 

By entering the most basic command to configure port security, we accepted the default settings of only allowing one MAC address, determining that MAC address from the first device that communicates on this switch port, and shutting down that switch port if another MAC address attempts to communicate via the port. But you don’t have to accept the defaults.

 

You can also configure port security on a range of ports. Here’s an example:

Switch)# config t

 

Switch(config)# int range fastEthernet 0/1 - 12

 

Switch(config-if)# switchport port-security

 

However, you need to be very careful with this option if you enter this command on an uplink port that goes to more than one device. As soon as the second device sends a packet, the entire port will shut down.

 

View the status of port security

 

Once you’ve configured port security and the Ethernet device on that port has sent traffic, the switch will record the MAC address and secure the port using that address. To find out the status of port security on the switch.

 

Switch# show port-security address

 

Disabling Port Security in Cisco Switch/Cisco Catalyst Switch

 

Now we will see an example how to disable port security in cisco security.We have configured fa0/22 for port security now if you want to disable port security follow these steps

Switch# config t

 

Switch(config)# int fa0/22

 

Switch(config-if)# no switchport port-security

 

Switch(config-if)# end

Cisco on UC for SMBs

October 26 2011 , Written by Cisco & Cisco Router, Network Switch Published on #Networking

Cisco is well known for its networking prowess and commitment to Unified Communications (UC) for the enterprise.  What may be less known is its equally deep commitment to UC for SMBs.  According to Cisco, SMBs can benefit from UC in several ways including;

  • Collaboration
  • Communication
  • Business Process Integration
  • Increased Productivity

I recently had the opportunity to speak with Mark Monday, Vice President and General Manager, Cisco’s Small Business Technology Group, to learn more about Cisco’s view of UC and the SMB market. 

TR: SMBs are often without technical specialists, so can you give us a plain English overview of UC?

Monday: Cisco has a small business technology group, and an effort around small business, is because we understand that they typically don’t have an IT professional on staff.  In fact, most of them go out of house for IT services in some way.  So they’re getting that IT professional service from a service provider or maybe even a local VAR in their community.  The question about UC for SMBs is really a combination of IP telephony and the ability to take that traffic, that IP phone call, and do something different with it than you might be able to do with a normal phone system.  For instance, capture voice mail and send it to your e-mail, thereby enabling you to use that information in multiple ways once it’s in your e-mail As examples, you might forward it or store it as text.  So, UC really brings together IP, telephony, and some of the applications used within the framework of the SMB all together into a solution.

 

TR: Where does Cisco fit in to this picture?

Monday: Cisco’s Small Business Technology Group primarily works with our channel partners who serve the customer.

Today, in the SMB sphere, we’re really seeing two primary methods used to get to UC.  They’re typically trading out an older phone system, usually a key system, which was probably acquired before the year 2000.  These systems have aged out in many ways such as expired warranties. Most SMBs are now moving to some sort of UC via either a service, operated by a service provider who offers them what might be defined as a hosted system, or a new premises-based UC system such as a Cisco UC 300 or UC 500.  While hosted services is a growing business it’s still a fraction of the premises-based implementations.

 

TR: UC is rapidly replacing POTS/PBXs at the enterprise level and you’ve stated that SMBs are moving to UC, but from my experience many seem reluctant.  What do you most often hear as their reasons for not implementing UC?

Monday: I haven’t really found a customer who doesn’t want to implement UC.  Then it’s a question of balancing the intensity of the requirement against the costs of acquisition, implementation and ongoing support. In these uncertain economic times, the value proposition has to be compelling.  I tend to see that everybody wants UC; the question is, when they move to it.

 

TR: Is there a generalized cost/benefit rule of thumb that SMBs can apply when evaluating UC?

Monday: Yes. There’s lots of that kind of material available on our own web-site and through our partners. Our partners tend to be able to walk in the customer’s door and walk them through a compelling ROI to move to a UC solution. A cost benefit example is that the new technologies use a different sort of trunking verses the older technology which required specific and specialized trunk for different features (e.g. separate phone lines and data lines).  Now all of that service can be supported on one single line so you can use your data connection for your phone through what’s called SIP trunking.  The immediate benefit is the cost saving from reducing your number and variety of trunks to one.

 

TR: I know that each implementation is different for a variety of factors so you can’t give us a blanket price, but what about benefits? What are the most common benefits received by SMBs who implement a UC solution?

Monday: One of the biggest benefits we see with our SMB customers is the ability to have an off-premises extension [OPX] to a home office at virtually no network cost because the home usually already has an Internet connection.  Although this may be possible with legacy telephone systems, implementation is generally difficult and prohibitively expensive. With UC today it’s possible today to take a phone home and connect it through a secure tunnel back to the office.  This way the phone at home behaves as though it’s your desktop phone at work, as a shared line, or a unique number at home.  So you can have someone working from home that needs to participate in the office business, but is unable to come into the office.  This same capability can be easily extended to temporary locations such as a vacation home.

  

TR: How do people find our more?

Monday: I encourage Cisco customers to connect with a service provider or local Cisco channel partner of ours.  Of course, people can visit http://www.cisco.com/go/smb to get a personal sense of what Cisco solutions can do for their business.

 

TR: Is there anything else you’d like to add?

Monday: We truly want to encourage SMBs to take advantage of the technologies that are available. We recognize that there haven’t been a lot of purpose built solutions for SMBs in the past. At Cisco we’ve learned from our successes with enterprise systems and leveraged that knowledge to develop rock-solid, purpose-built SMB solutions. So we can take some of the pain away, if you will, and deliver enterprise like technology to SMBs

Cisco 1841 Modular Router: Q&A to Its Full Background and Features

October 19 2011 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Routers

Cisco-1841-Modular-Router-Q-A-to-Its-Full-Background-and-Fe.jpg

Q. What are the Cisco 1800 Series Integrated Services Routers?

A. The Cisco 1800 Series is part of the Cisco Integrated Services Router product line. The Cisco 1800 Series consists of the Cisco 1800 Series fixed routers and the Cisco 1841 modular router.

 

Q. Why did Cisco Systems introduce the Cisco 1800 Series?

A. Cisco introduced the Cisco 1800 Series to allow the secure deployment of multiple, integrated services at wire-speed performance. In general, the integrated services router product line provides high performance while running simultaneous services such as data, security, and quality of service (QoS) in one integrated routing platform. The best-in-class Cisco 1800 Series architecture has been specifically designed to meet requirements of small-to-medium-sized businesses (SMBs) and small enterprise branch offices as well as service provider-managed services applications. The Cisco 1800 Series delivers secure concurrent services at wire-speed performance and allows for lower operational and capital expenditures because of the high degree of integration and ease of installation, management, and deployment.

 

Q. What is the Cisco 1841 Integrated Services Router?

A. The Cisco 1841 is a modular router that is designed to intelligently integrate data and security services into one single, resilient system for fast, scalable delivery of mission-critical business applications. It is specifically engineered for customers who want to securely deploy multiple, concurrent services at wire-speed performance with security and QoS features enabled. The Cisco 1841 comes in a desktop form factor with two modular WAN-interface-card (WIC) or high-speed WIC (HWIC) slots for data connectivity. It offers hardware-based encryption for Data Encryption Standard (DES), Triple DES (3DES), Advanced Encryption Standard (AES), and Secure Sockets Layer (SSL) VPN as well as Cisco IOS® Firewall and Cisco IOS Intrusion Prevention System, which can be enabled through an optional Cisco IOS Software security image. The Cisco 1841 router provides two integrated 10/100BASE-T Fast Ethernet ports onboard, an integrated USB port (1.1), as well as an internal advanced-integration-module (AIM) slot. The modular form factor of the Cisco 1841 helps ensure investment protection with WICs and HWICs that are compatible with the Cisco 2800 and Cisco 3800 Series Integrated Services Routers.

 

Q. With the introduction of the Cisco 1800 Series, what are the plans for the current Cisco 1700 Series Modular Access Routers?

A. The Cisco 1700 Series will reach end of sale on March 27, 2006. New feature development for the Cisco 1700 Series will be available through Cisco IOS Software Release 12.4T with bug-fix support through Cisco IOS Software Release 12.5 Mainline.

 

Q. Does the Cisco 1841 offer a bundled security, data, and broadband solution similar to the Cisco 1700 Series?

A. Yes. Bundled security solutions with support for hardware-based encryption for DES, 3DES, AES, SSL VPN, Cisco IOS Firewall, and Cisco IOS Intrusion Prevention System are available for the Cisco 1841. Bundled data and DSL solutions are also available for the Cisco 1841.

 

Q. What is the performance of the Cisco 1841?

A. The Cisco 1841 is a new-generation, best-in-class router platform designed to deliver multiple concurrent services at wire-speed performance up to single T1/E1/xDSL speeds. Chassis performance has been increased up to five-fold, and security performance increased up to seven-fold compared to the Cisco 1700 Series. The single T1/E1/xDSL value quoted here represents IMIX packet sizes in higher-than-typical Cisco 1841 services configurations. In less service-heavy environments, actual WAN throughput
will be higher.

 

Q. How does the Cisco 1841 router compare to the Cisco 1721 router that is the current Cisco 1700 Series data-only version?

A. The Cisco 1841 router provides significant additional value compared to the Cisco 1721 router by offering more than a five-fold performance increase. It also integrates hardware-based encryption that can be enabled with an optional Cisco IOS Software security image while simultaneously supporting multiple services such as security, data, and QoS, and providing increased slot performance and density. Also, more than 30 existing Cisco 1700 Series WICs and multiflex trunk interface cards (voice WICs [VWICs]) (for data only) are supported. Further, both of the modular slots on the Cisco 1841 router are HWIC slots that offer greater speeds and higher port density.

 

Note: The WIC/HWIC/VWIC (in data mode only) slots on the Cisco 1841 router do not support Cisco product-based inline power,
or Power over Ethernet (PoE). This support is offered beginning with the Cisco 2801 Integrated Services Router as part of the Cisco 2800 Series.

 

Q. What are the basic specifications for the Cisco 1841 router?

What Does Cisco Attract You?

October 18 2011 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Technology - IT News

Cisco provides a network that can securely and reliably handle all types of traffic, throughout the entire network, over virtually any media, while providing consistent service delivery to all users.What-Cisco-attract-you.jpeg

 

Cisco is proud of being a recognized worldwide leader in networking. Now, when the technology industry is going through a period of dramatic change, it remains the market leader in multiple areas, such as routing and switching, unified communications, mobility, and security. The company helped catalyze the industry's move toward IP, and, now that it is fully under way, Cisco is at the center of fundamental changes in the way the world communicates.

 

Innovation, something indispensable, helps Cisco and famous companies win customers’ praise. And this reputation is caused in part by the Cisco development strategy of "build, partner, and acquire." Beyond corporate innovation, Cisco also helps to shape innovation throughout the industry by actively participating in virtually every group concerned with networking standards.

 

To be simple, as a company whose own success depends on its network systems, Cisco fully understands this relationship. In today's environment of mergers, acquisitions, and global expansion, businesses now require network systems that enable technology innovation and business-critical services not only at the headquarters, but across geographically disparate corporate campuses, throughout the branches, and out to remote workers. Cisco can provide an end-to-end network, composed of systems specifically designed to address the unique needs of each place in the network, connected by a common infrastructure and a common operating system and manageable from a central location as a single, cohesive entity.

 

Because Cisco envisions the network as a whole, it designs and develops products, technologies, and solutions that provide business benefits across the entire network. Consider, for example, the enablement of advanced technologies. Advanced technologies, such as voice over IP (VoIP), require the support of intelligent network services. Although many networking vendors support these services, the level and methods of support often vary from one device to another and from one place in the network to another, making configuration and interoperation difficult. With Cisco network systems, intelligent network services, such as quality of service (QoS) and encryption, are consistently supported and preserved across the entire network, enabling the same secure and high-quality service delivery regardless of whether the user is at headquarters or in a local branch.


 

Cisco-copy-1.jpegCisco applies this same broad view to network management, providing tools to manage the network as a whole. For example, the Cisco integrated services routers use 802.1ag to provide end-to-end service manageability. Another example is the Cisco Network Application Analysis (NAPA) Solution, which also takes a holistic approach to management, providing an end-to-end view as it monitors and analyzes the entire network to optimize the relationship between application performance and network resources.

 

Moreover, Cisco understands the relationship between all elements of the network: that an improvement in management or security capabilities can often mean a decrease in performance. Cisco is constantly looking for innovative ways to eliminate these types of tradeoffs. One such innovation is the Cisco Catalyst 6500 Supervisor Engine 32 Programmable Intelligent Services Accelerator (PISA), which eliminates the tradeoff by providing hardware acceleration of intelligent services, such as stateful application intelligence and day-zero security services, at multigigabit speeds.

 

In most cases, the network of a company or organization is not a single island. It is likely made up of multiple networks, including one or more campuses, some number of branches, remote teleworkers, and one or more data centers, all connected through a WAN or MAN. These businesses and organizations require solutions that work across the entire network, throughout all "places in the network."

 

Cisco understands and addresses the unique requirements of each place in the network:

 

Campus: Market factors are causing a shift in corporate structures. Reduced time to market translates to a greater need for interaction throughout a company. And as these companies become more adept and more dependent on technologies for this interaction, the network must provide a platform that enables and promotes enhanced communication and collaboration.

Cisco provides a platform designed for collaboration with the Campus Communication Fabric, which enables application proficiency, secure multimedia communications, improved productivity and innovation, business continuity, and efficient operations over a flexible infrastructure.

 

Branch/WAN: Historically, branch users have not been given the same priority as users at headquarters, enduring less-than-optimal response times, receiving a subset of services, and experiencing downtimes that are not tolerated at headquarters. But this is changing. Because of the increased number of acquisitions and mergers, along with the focus on local presence and global expansion, remote office workers have gained significant importance in the equation for business success. Today's branch users require the same consistent delivery of services and applications as headquarters users.

 

Cisco gives branch users an equal status with the Empowered Branch, which integrates the widest set of services and applications while optimizing their interoperability and performance for a consistent branch experience. At the WAN headend, Cisco offers services aggregation solutions that combine virtualized services integration, bandwidth optimization, and application intelligence to provide secure, intelligent routing of applications across the enterprise WAN.

 

Data center: The rapid proliferation of new applications combined with the increased complexity of these applications mean that IT managers require data center architectures that are more resilient, more adaptable, more manageable, and capable of serving users across geographically dispersed locations.

 

Cisco data center solutions are built on the principles of consolidation, virtualization, and automation to provide the security, availability, manageability, and optimized application delivery that enable superior service delivery and application performance.

 

 

Network Systems Components You Need to Know

When you look closer into each of these network systems, you find components that are industry leaders in their own right. Cisco provides one of the most robust, intelligent lines of integrated services routers, along with one of the most comprehensive, feature-rich portfolios of network switches.

 

Routing

Cisco routers allow organizations to build a foundation for an intelligent, self-defending network, featuring best-in-class security services and routing technologies for a low total cost of ownership and a high return on investment. These routers offer:

• Industry-leading services densities, bandwidth, availability, and performance options for maximum configuration flexibility and scalability for the most demanding networking environments

• Superior services performance and investment protection

• An integrated systems approach to embedded services that speeds application deployment and reduces operating costs and complexity

 

For the branch, Cisco provides a portfolio of routers designed for secure wire-speed delivery of concurrent wireless, data, voice, and video services with superior investment protection. Cisco integrated services routers embed security, mobility, LAN switching, and voice services inside the router as a single resilient system for ease of deployment, simplified management, and lower operating costs. They also support leading-edge WAN technologies, such as:

Optimized Edge Routing (OER), which helps enable intelligent network-traffic load distribution and dynamic failure detection of data paths at the WAN edge

• Group Encrypted Transport (GET) VPNs, a highly-scalable, tunnelless form of virtual private networking

• Wide-Area Application Services (WAAS), which combine application acceleration technologies with WAN optimization techniques

 

In addition to convenience, the Cisco integrated services routers provide investment protection. The integrated design enables a 70 percent reduction in operational expenses when compared to deploying multiple overlaid components in a branch to achieve the same services. Additionally, the modular design of the Cisco integrated services routers allows for easy integration of new services as well as the expansion of existing ones.

 

At the headend, Cisco offers an extensive WAN and MAN aggregation platform portfolio, which also provides a comprehensive set of highly secure, concurrent, and integrated services. Cisco services aggregation routers provide exceptional performance with aggregation speeds of up to 2 Mpps and support for as many as 16,000 Point-to-Point Protocol (PPP) sessions and 5000 VPN sessions per chassis. For optimization, these routers also support Network-Based Application Recognition for application optimization and OER. To help ensure the security of your network, these routers include support for IP Security (IPsec) encryption, an integrated stateful firewall, and support for identity-based access control.

 

Switching

Cisco offers a comprehensive portfolio of intelligent network switches, with a continuously expanding suite of intelligent services and advanced technologies to strengthen, simplify, and extend the value of the network infrastructure. As a leader in switching technology innovation, Cisco is constantly developing new ways to enable its customers to get more from their network infrastructure. Many Cisco innovations have evolved into industry standards, including Cisco EtherChannel (now the 802.3AD standard), Power over Ethernet (now the 802.3af standard), Multiple Instance Spanning Tree (now the 802.1s standard), and Interswitch Link (now the 802.1q standard).

 

Cisco Catalyst switches are based on a superior design that employs a centralized architecture, which simplifies expansion and upgrades. They also use application-specific integrated circuit (ASIC) technology, which is better suited than merchant silicon (used by many other switch vendors) for the delivery of advanced features.

 

Additionally, Cisco Catalyst switches provide:

Superior service delivery from the wiring closet to the core, from the data center to the WAN edge with 10/100/1000 to the desktop, Fast Ethernet through 10 Gigabit Ethernet connections, and predictable wire-rate switching performance (even with QoS enabled)

• High level of availability with In-Service Software Upgrade (ISSU) and hot-swappable modules, which enable easy upgrades without service interruption, and nonstop forwarding with stateful switchover (NSF/SSO), which reduces the mean time to repair (MTTR) by allowing extremely fast supervisor switchover that is virtually transparent

• Exceptional scalability through options such as virtualization, which provides for the centralization of services and security policies while preserving the high-availability, manageability, security, and scalability benefits of the existing campus design (centralized management and security), and Power over Ethernet, which simplifies the addition of new endpoints

• Superior security with integrated support for identity-based access control and Cisco Catalyst integrated security features, as well as Cisco firewall and intrusion detection modules

• Industry-leading support for converged applications, including voice, video over IP, and mobility

 

For your business growth and success, this network should be a Cisco network. When you join the intelligent, resilient routing offered by the Cisco routing portfolio with the innovative high-performance switching offered by Cisco Catalyst switches; connect them through reliable, scalable Cisco IOS Software innovation; and manage them with the automated, integrated management offered by the Cisco network management portfolio, the result is a highly available, adaptable infrastructure that delivers secure, pervasive services through a cohesive network platform upon which you can deploy technology solutions that address today's business challenges and enable tomorrow's business success.

 

Having Cisco network systems throughout your network helps to accelerate deployment of new technologies, reduce the learning curve in your IT staff, protect the integrity of your network and the data that crosses it, and enables your users to achieve higher levels of productivity and responsiveness.

 

Add to this Cisco industry leadership, financial stability, commitment to innovation, and dedication to customers, and it is clear that Cisco is an excellent choice for your network systems: yesterday, today, and tomorrow.

Is the Next Cisco Systems Really Here?

October 11 2011 , Written by Cisco & Cisco Router, Network Switch Published on #Cisco Switches - Cisco Firewall

And so it begins. After a bleak summer that included 6,500 job cuts, Cisco Systems (CSCO) is working hard to raise its voice and rally partners. Channel Chief Edison Peres has issued a video blog to crystallize the company’s partner strategy. Andrew Sage, Cisco’s VP, Partner Led, is set to provide strategy updates soon. And CEO John Chambers (pictured) recently rallied the Cisco sales force to further support partners. All of the chatter includes Cisco executives talking about the “Next Cisco.” But has the Next Cisco really arrived?Cisco-Here.jpg

 

In the video blog, Peres reinforces the fact that 80 percent of sales involve partners:

As expected, Cisco has also simplified its messaging. Instead of focusing on roughly 50 markets, Cisco is zeroing in on five opportunities:

  1. Core (routing and switching)/Cisco Routers & Cisco Switches
  2. Collaboration
  3. Data center/virtualization
  4. Video
  5. Architectures for business transformation

Some folks on Wall Street are embracing Cisco’s streamlined focus. Auriga USA, an institutional broker, predicts that Cisco can grow faster than rivals over the next years while taking market share from Hewlett-Packard and Juniper Networks, according to Tech Trader Daily,

 

Still, let’s not forget that Cisco stumbled badly only a few months ago. First, the company essentially said “all is well” during Cisco Partner Summit (Feb. 28-March 3, 2011). But by April, Chambers conceded that Cisco had lost its focus. Cisco soon killed the Flip video camera. And by August 2011, Cisco cut roughly 6,500 positions.Cisco-right-here.jpg

 

But here’s where things get extra interesting. Sometime around the time Cisco started layoffs, Wall Street began to think that Cisco was in better shape than some of its rivals. And more recently, Hewlett-Packard’s decision to potentially sell or spin-off its PC division may have triggered some distractions within the halls of HP… potentially helping Cisco to gain some ground in the server market (though servers are not part of HP’s potential PC spin-off plan).

 

Yes, Cisco still has massive market share in switching and routing. And folks like Peres and Sage have the channel’s respect. But here’s one remaining riddle: How exactly does Sage’s role differ from Peres’s role? The VAR Guy expects to gain more answers and insights within the next few days…
