Whenever you are preparing for the Cisco CCNA ®, Cisco CCNP®, and Cisco CCIP® certifications especially when you are doing a self-study the major concern is lab experience to answer the simulated questions. Often many of us end up looking for real Cisco hardware from eBay, as most of the present day simulators fail to fulfill our requirements. To certain extent GNS3 did an amazing job by emulating the power of Cisco IOS in our machines. But GNS3 does have some limitations; when it comes to switching GNS3 have no answer.
Current high end systems fail to handle most complex GNS3 topologies. To ease all these hurdles Cisco has an answer. Yeah you can experience the Cisco real labs. A more flexible option is here known as Cisco Learning Labs. For the first time, Cisco certifications aspirers can secure hands-on Cisco IOS® Software lab practice for both routing and core switching.

When you are preparing for Cisco CCNP- Switch Exam, IP SLA is one of the key topics included at quite later stage even surprised David Hucaby the author of the title “CCNP Switch Official Certification Guide” Even he included the supplementary material for the “CCNP Switch Official Certification Guide”
The Cisco IOS IP Service Level Agreement better known as IPSLA is a feature which was introduced in the IOS version 11.2 under the name of Response Time Responder (RTR). Later on Cisco sensed RTR is creating some sort of confusion as some of reference texts referred RTR as Real time responder; hence they renamed RTR as Service Assurance Agent (SAA). Even SAA didn’t stick for long time and now it’s known as IP SLA. IP SLA is truly excellent for built-in network testing. In fact, it is a key ingredient for sophisticated implementations of Performance Routing (PfR).
At its introduction in IOS 11.2 version under the name of RTR it had very limited offerings
- ICMP Ping
- ICMP Echo Path
- IBM SNANativeEcho
The Cisco IOS IP Service Level Agreement (IP SLA) feature can be used to gather realistic information about how specific types of traffic are being handled end-to-end across a network. To do this, an IP SLA device runs a preconfigured test and generates traffic that is destined for a far end device. As the far end responds with packets that are received back at the source, IP SLA gathers data about what happened along the way.
IP SLA is capable of running following tests in Cisco Switches and routers
|Test Type||Description||IP SLA Required on Target?|
|icmp-echo||ICMP Echo response time||No|
|path-echo||Hop-by-hop and end-to-end response times over path discovered from ICMP Echo||No|
|path-jitter||Hop-by-hop jitter over ICMP Echo path||Yes|
|dns||DNS query response time||No|
|dhcp||DHCP IP address request response time||No|
|ftp||FTP file retrieval response time||No|
|http||Web page retrieval response time||No|
|udp-echo||End-to-end response time of UDP echo||No|
|udp-jitter||Round trip delay, one-way delay, one-way jitter, one-way packet loss, and connectivity using UDP packets||Yes|
|tcp-connect||Response time to build a TCP connection with a host||No|
As I am working with Nexus 7000, Nexus 5000 and 2000 Series Switches, I discovered by default Telnet Server is disabled in a NX-OS devices such as Nexus 7000, Nexus 5000 and 2000 Series Switches.
We all know Telnet protocol enables TCP/IP connections to a host. Telnet allows a user at one site to establish a TCP connection to a login server at another site and then passes the keystrokes from one device to the other. Telnet can accept either an IP address or a domain name as the remote device address.
I will show you how to enable the Telnet Server in NX-OS devices
VDC-Admin(config)# feature telnet
VDC-Admin(config)# show telnet server
telnet service enabled

Perhaps it’s better for the time being to disable the flash. According to the Adobe Security Advisory (APSA11-01) post there is a critical vulnerability exists in Adobe Flash Player 10.2.152.33 and earlier versions (Adobe Flash Player 10.2.154.18 and earlier for Chrome users) for Windows, Macintosh, Linux and Solaris operating systems, Adobe Flash Player 101.106.16 and earlier versions for Android, and the authplay.dll component that ships with Adobe Reader and Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh operating systems. There are reports that this vulnerability is being exploited in the wild in targeted attacks via a Flash (.swf) file embedded in a Microsoft Excel (.xls) file delivered as an email attachment. At this time, Adobe is not aware of attacks targeting Adobe Reader and Acrobat
Adobe is in the process of finalizing a fix for the issue and expect to make available an update for Flash Player 10.x and earlier versions for Windows, Macintosh, Linux, Solaris and Android, and an update for Adobe Acrobat X (10.0.1) and earlier 10.x and 9.x versions for Windows and Macintosh, Adobe Reader X (10.0.1) for Macintosh, and Adobe Reader 9.4.2 and earlier 9.x versions during the week of March 21, 2011
When you are preparing for the CCNP Switch (642-813) or BCMSN exam (642-812) there are quite a few topics which are important not only from the perspective of passing the “Implementing Cisco IP Switched Network” exam or BCMSN exam but also for the day to day network troubleshooting tasks.
One among the key topic is “spanning tree loop guard”. As the name itself suggests Loop Guard is a method used for ensuring no spanning tree protocol loops (STP) occurs in any network topology. Though STP loop guard feature can prevents STP loops as best it can, still chances of loops are there due to unidirectional link failure or congestions issues in the Cisco Switch. It’s always recommended, the loop guard feature to be used in conjunction with UDLD feature. I will cover about UDLD feature in one more article.
The basic function of loop guard feature is to prevent loops conservatively by preventing alternate or root ports from becoming DPs in the topology. If BPDUs are not received on a non-Designated Port, and Loop Guard is enabled, that port is moved into the STP loop-inconsistent Blocking state, instead of the Listening /Learning / Forwarding state.
Loop Guard operates only on ports that are considered point-to-point by the spanning tree, and it cannot be run in conjunction with Root Guard on an interface.
To enable Loop Guard on a Cisco Catalyst Switch, you can use the following IOS command in the global configuration mode
Microsoft Chief Research and strategy officer Craig Mundie and Don Mattrick, president of Microsoft’s Interactive Entertainment Business, have announced the release of a non-commercial Kinect for Windows software development kit (SDK) from Microsoft Research.
The newly designed SDK kit will give developers access to audio, programming interfaces, system application, and direct control of the Kinect sensors, so that they can create new applications based around the motion sensing device.
Microsoft plans to release a commercial version at later date , but the SDK will be a starter kit designed to make it simpler for the academic research and enthusiast communities to create rich natural user interfaces using Kinect technology.
“Microsoft’s investments in natural user interfaces are vital to our long-term vision of creating computers that are intuitive to use and able to do far more for us,” said Mundie. “The fruits of these research investments are manifesting across many of our products, Kinect for Xbox 360 among them.”
Microsoft is continuing to make developments and investments in natural user interfaces and its developments are appearing in Microsoft products such as Kinect for Xbox 360, Windows Phone 7, Microsoft Surface 2.0, Bing for mobile and Office 2010 Mini Translator
According to Cisco 2010 Annual Security Report, Windows-based Systems are less prone to attacks from spammers
According to Cisco 2010 Annual Security Report, scammers are targeting other operating Systems, platforms , mobile platforms, smart phones and tablets, rather than their prime focus Windows – based systems. The good news is that Windows-based Systems are less prone to attacks from spammers and cyber criminals
The report also shows that 2010 was the first year in the history of the internet that spam volumes decreased. However, despite a global shrinkage in spam, developed countries with broadband internet connections saw an increase in spam. These countries include France, Germany and the United Kingdom. In the United Kingdom spam volumes rose almost 99% from 2009 to 2010.
Some of the notable articles include in the Cisco 2010 Annual Security Report are
- Money Mules: The Linchpins of Cybercrime Networks
- Social Engineering: The “Seven Deadly Weaknesses” That Criminals Exploit
- Criminals Favoring Java Over PDFs
- Global Spam Update: Spam Down Globally, but on the Rise in Europe
- Android and Apple Operating Systems Likely Key Targets in 2011
Cisco’s report showed in increase in money mulling, where people are recruited to set up bank accounts or use their own to help scammers launder money. For futher details on the report do download the Cisco 2010 Annual Security Report
