When it comes to Cisco Embedded Event Manager (EEM) on Cisco Nexus platform it slightly differs from the Cisco Catalyst 6500 Switch platform. In Cisco Nexus platform each line card module runs its own instance of EEM subsystem (an EEM Client), which results in handling of EEM events locally by the respective line card module. This in turn frees the supervisor Engine resources from managing the EEM event publication and executing policies across the chassis.
One more great advantage of distributed architecture is it further improves the latency of time taken to invoke the EEM policy execution.
Cisco Embedded Event Manager better known as EEM is a powerful feature included in Cisco IOS such as IOS-XR, IOS-XE and NX-OS. The Cisco EEM in simple terms is a technology developed by Cisco systems which allows you to run a script or a set of command upon an event.
The Cisco EEM allows the behavior of a Cisco device to adapt to specific user requirements by allowing scripting, thresholding, proactive actions, data collection and event management inside the Cisco device itself. Using EEM, problems can be identified and resolved automatically in advance by setting event triggers (called Event Detectors) to watch for specific types of situations or thresholds, or run a set of actions periodically.
With EEM, users can capture complex network events and run sophisticated programs on Cisco devices. The version of EEM on most Cisco devices is version 2.1, and the latest version is 3.0 which was introduced in IOS 12.4(22)T. EEM consists of three areas; Event Detectors, Policies and Programming languages.
When a situation is detected by EEM, it uses policies to invoke actions based on the type of event and the configured policy.
Last year I was eagerly waiting for the first Cisco Live of Middle East in Bahrain. But it was cancelled and I was disappointed. This year I was wondering when Cisco Systems with come out with their annual Cisco Expo Event. Yesterday while I was talking to one of the Cisco representative I came to know about the Cisco Expo 2011.
Cisco Systems are conducting the Cisco Expo Saudi Arabia, on the 5th and 6th of December 2011 at the King Fahad Cultural Centre, Riyadh Saudi Arabia. This year Cisco came out with a theme “Innovate Together”. Well I am sure this event provides a great opportunity to connect, collaborate and communicate with leading IT professionals in the region. Cisco Expo is a platform where we get an opportunity to discuss a variety of topics ranging from global megatrends, their societal and economic impact, to innovation and relevance to the technology architectures.
Cisco System and their partner have planned few presentations and demonstration will focus around the power of collaboration, video, cloud and virtualization, borderless network and emerging technologies that are transforming business to networked enterprises driving business results, productivity, competitiveness and societal change.
So want to be at Cisco Expo Saudi Arabia, register now.
Recently Cisco announced the introduction of new portfolio of switching products to augment the Cisco Unified Fabric product range. This range consists of Nexus data center switches and MDS storage switches that connect servers, data storage, and corporate networks seamlessly within the data center and cloud.

Cisco Systems announces the new Fabric 2 modules for Cisco Nexus 7000 Series switches. The newly announced Cisco Nexus 7000 Series Fabric-2 Modules for the Cisco Nexus 7000 Series chassis are separate fabric modules that provide parallel fabric channels to each I/O and supervisor module slot. From a scalability perspective, the new Fabric 2 module, enables the deployment of up to 768, 10 GbE ports in a Nexus 7000 chassis. The Fabric 2 module can deliver up to 550 Gbps per slot of performance. The new module also delivers connectivity, for only 9 watts of power per port.
Through the parallel forwarding architecture, a system capacity of more than 15 Tbps is achieved with the five fabric modules. The fabric module provides the central switching element for fully distributed forwarding on the I/O modules.
The newly announced Fabric 2 modules for Cisco Nexus 7000 Series switches is available for Cisco Nexus 7009, 7010 and 7018 Chassis. It seems Cisco Systems are coming out with a 9 slot chassis for Nexus 7000 Series Switch. The Fabric 2 module in combination with the supervisor and I/O modules supports virtual output queuing (VOQ) and credit-based arbitration to the crossbar switch to increase performance of the distributed forwarding system. VOQ and credit-based arbitration facilitate fair sharing of resources when a speed mismatch or contention for an uplink interface exists. The fabric architecture also enables future support for lossless Ethernet and unified I/O capabilities.
Some of the features and befits of the Cisco Nexus 7000 Series Fabric Modules are as follows
When it comes to preparation for Cisco CCNP TSHOOT 642-832 exam, you are not left with many choices, among the available the best sources are Cisco Press books. Personally for me, my experience helped me to pass the Cisco CCNP TSHOOT 642-832 exam. But for those who are new to industry they are dependent on study guides and CBT nuggets.
When it comes to study guides still Cisco Press titles are far superior to other publications. The Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” follows the typical Cisco Press approach, each chapters begins with “Do I know this Already?” quiz and then followed by the subject. This approach is good as it lets you know to determine the knowledge level of the topic; it gives a brief idea to plan out the approach for each chapter. The title comprises of 15 chapters and the final chapter deals with the final preparations for the exam.
The good thing I like about this title is the way how author “Kevin Wallace” presented the known topics from different perspective. Yeah he was quite successful in engaging with his readers and presenting the troubleshooting techniques. The inclusion of many case studies enhanced the author’s presentation and he was quite successful in reaching out the mass. Especially for those who passed CCNP Route and Switch exam they find not much in this title, but they will learn the troubleshooting and maintenance techniques for complex networks. The troubleshooting scenarios and methodology grabbed my attention and I like the way troubleshooting tickets were presented.
I have few suggestion to Cisco Press is to include the pdf version of the title with the CD. The CD also came with the Boson Exam Environment Engine (BEE), it was a huge disappointment for me as the practice exam failed to contain the simulated scenarios. The BEE contained only multiple choices, single choice, drag and drop style questions.
Overall the Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” is a good source for anyone who is preparing for Cisco CCNP TSHOO 642-832 exams and a helpful guide for those who wants to master troubleshooting.
Last week Cisco Systems announced its intention to acquire BNI Video, headquartered in Boxborough, Mass.,. BNI Videos are involved in supping video products to service providers that offer video back-office and content delivery network (CDN) analytic capabilities. This announcement is quite evident about Cisco intention to expand its capabilities in its Videoscape TV platform. The main aim of videoscape is to allow service providers to deliver compelling video experiences to any device over any Internet Protocol (IP) network.
“Cisco is committed to working with our service provider customers to deliver next-generation IP-based video experiences across devices,” said Marthin De Beer, senior vice president and general manager of Cisco’s Emerging Business Group. “Service providers globally are embracing our Videoscape vision, and today with the acquisition of BNI Video, we are augmenting our Videoscape platform and giving customers a clear migration path to Videoscape.”
“As a founding investor in BNI Video, Comcast Ventures recognized the potential for this technology to play a critical role in advancing video experiences for Comcast’s customers,” said Tony Werner, chief technology officer, Comcast. “With the combined expertise in IP video systems, Cisco and BNI Video offer service providers a compelling software and infrastructure platform to efficiently deliver video content to multiple devices.”
“Time Warner Cable invested early in BNI Video, as it brought a unique software platform to market that addresses the back-office complexities of delivering TV Everywhere services,” said Mike LaJoie, chief technology officer, Time Warner Cable. “Combining forces with Cisco presents an opportunity to take video service providers to the next level with Internet video, helping to manage networks more efficiently to deliver advanced TV entertainment experiences to consumers.”
Upon the close of the acquisition, BNI Video employees will be integrated into Cisco’s Service Provider Video Technology Group. Under the terms of the agreement, Cisco will pay approximately $99 million in cash and retention-based incentives in exchange for all shares of BNI Video. The acquisition is subject to various standard closing conditions and is expected to be complete in the second quarter of Cisco’s fiscal year 2012.
How to pass Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam? – Series 2
For those who are new to Cisco Domain, I strongly recommend them to read the Cisco Press title which for sure will help them to understand the approach they must apply, especially whenever they are troubleshooting any problem in a complex Cisco Network. Also I strongly suggest building a GNS3 topology based on solutions provided in the Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” and you can also make use of Cisco Press title “CCNP TSHOOT Lab Manual“.
The best thing I like about this lab manual is all configuration files can be downloaded from Cisco Press website. Practice makes man perfect; by troubleshooting various scenarios, which you can build using the above mentioned resource can help you in mastering CCNP TSHOOT topics and can, learn the various approach adapted to trouble shoot more complex Cisco networks. Of course nothing can replace the practical experience but when you simply don’t have that privilege, you can make use of GNS3.
I am hopeful by simply passing Route and Switch exam; you will gain enough confidence and expertise to pass the Cisco TSHOOT exam. Better luck for those who are appearing for the TSHOOT exam, make sure you watch THSOOT Strategies on YouTube by Kevin Wallace which does give you an idea how the real exams look like and do practice the CCNP TSHOOT demo exam available at Cisco web site.
How to pass Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam? – Series 1
Dear CCNP Certification aspires, the moment you pass the Cisco CCNP Route (642-902) and CCNP Switch (642-813) exams consider yourself you are ready for the Cisco CCNP TSHOOT (642-832) exam. The Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam basically aims at testing you knowledge and skills to plan and perform regular maintenance of complex Enterprise Switched and routed networks along with testing your skills well known network maintenance models like Cisco Lifecycle Services, FACPS, ITIL and TMN.
The secret behind passing the Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exam depends on how good you are at troubleshooting, your experience on maintain and managing complex networks, and of course the courage to challenge yourself by focusing and thinking logically on tickets appear on the real TSHOOT exam.
Since I passed the Cisco CCNP Troubleshooting and Maintaining Cisco IP Network (CCNP TSHOOT, 642-832) exams I was mentally ready to take the challenge of Cisco TSHOOT exam, but my busy schedule was preventing me. Finally I set the date when should I appear for the Cisco TSHOOT exam and I came out passing the exam. Believe me, it was the easiest Cisco Certification exam I appeared till date in my life.
When it comes to exam preparation I got hold of Cisco Press title “CCNP TSHOOT 642-832 Official Certification Guide” and checked the latest exam topology published by Cisco Systems. Yes Cisco System does reveal the topology which appears on the real exam, which itself will ease your burden of preparations. Since I possess over a decade of experience on maintaining and managing Complex Cisco Networks I didn’t find myself reading the Cisco Press title from cover to cover. Just read first two chapters for the sake of curiosity. But prepared the GNS3 topology based on the exam topology published by Cisco Systems and practiced few scenarios. I will cover the approach need to be adopted by CCNP aspirers who are pretty new to Cisco Networks in the upcoming post.
Currently we are working on the power calculation and the heat dissipation by the Data Center Switches. Rather looking at each individual catalog, I figured out Cisco Systems are offering a dynamic tool which helps to calculate the total power required, typical output power, total heal dissipation.
The tool is known as Cisco Power Calculator (CCO login required):/
This utility asks you the type of switch you are using, what kinds of modules you are using, type of supervisor engine etc. After providing all the details the utility provided you a in depth report and you can download the same in an excel sheet or in pdf format. I am attaching the sample report which I calculated for one of our Cisco Catalyst 6513 Switch.powercalc_catalyst_6500_09-27-2011
