This intuitive network can automate mundane day-to-day operations, which shifts IT time and money to focus on creativity and design. Cisco IOS XE continually evolves and transforms to anticipate customer needs with exponential results, creating and driving new industries and fostering innovations that have yet to be envisioned. At Cisco, security is our top priority.
In addition to offering industry-leading security products and services, Cisco is building in security and trust across our solutions portfolio. That includes switches, routers, servers, and cloud solutions. Our approach is much more than just adding security as an afterthought to existing products. The result is that security is a primary design consideration, deeply integrated into the underlying architecture. This built-in security provides platform integrity, facilitates secure communications, guards against counterfeit products and tampering, gives customers confidence that their Cisco products are genuine and unmodified, and helps make sure that the data coming from your Cisco infrastructure can be trusted.
These features have positive compliance implications for our customers. For example, validation of a digital signature on the Cisco IOS Software installed on a platform is evidence that an auditor can use to state that the software on that platform is genuine and unmodified. Table 1. Primary features. If you want to be able to critically analyze your Cisco platforms with a firm understanding of the internal workings within the router, this is a fantastic book.
Perhaps the greatest part of the book was the end - it ties everything together with applied QoS. The need for QoS becomes so apparent, since the operation of the router is no longer a mystery. After readings this book, you will be competent in the understanding of the operation of the Cisco router I feel like I robbed Cisco Press and the authors. I was looking for this information to supplement the information provided in the support exam documentation and the performance field guide from MG Hill, and online docs.
This book has great information but does need to have a different name as I thought this would be more geared toward how the IOS was actually programmed and give a better understanding of IOS versions. If you troubleshoot networks this is part of the magic bullet needed to help in understanding memory and memory pool allocation, IOS Resource Management, processes, CPU, buffers, and cache.
The book spends quite a bit of time on large scale routers and needs to give a bit more focus on smaller scale equipement, also the information on Netflow is only 5 pages long. Awesome, I got this book and is like new. Thank you so much :. This book centers around buffer allocations and buffering problems. It will give you a better understanding of when different buffers are used.
You definitely have to read between the lines to fill in what all is happening to the data as it flows through the router in different ways. This is not a book for beginners. Excellent book for anyone wanting to know exactly how Cisco IOS software and router hardware really works. Functionally complete explanation of the different switching methods that IOS employs, as well as an in-depth view of a few hardware architectures. Also includes a large poster-size flow chart in the back of the book illustrating the steps packets take from being received to being routed and sent back out for several different architectures.
Book has a lot of good info but it's short on details. For example, the discussion on processes is informative but doesn elucidate on which process is which priority and what scenerios can prempt the priorties. You will have to look at the output of a router yourself to figure this out. Of course getting the same info from Cisco TAC is almost impossible! Good reference on the internal architecture of the the and series boxes. Overpriced for the quantity of info but worth-while addition to a reference library.
