“No IP Routing” was the answer

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


Recently one of our vendor added couple of new Cisco Catalyst 4506 Series distribution switches to our network for their PACS project.  Those two newly added Cisco 4506 Series distribution switches are connected to our Core Cisco Catalyst 6513Series Switches using a layer 23 uplink ( as a trunk port). For VLAN redundancy we are using HSRP protocol. The newly added Cisco 4506 Series distribution switches are configured in VTP Client mode, we could see the VTP status was updated and all the VLAN were created. But there was a problem; there was not communication between any of the VLANS in the new Cisco 4506 Series distribution switches, after trouble shooting we figured out “ip routing” was enabled. When we disabled the ip routing with “no ip routing” command everything started working.

Yasir Irfan Yasir Irfan Profile: Yasir Irfan

AMD has revealed details of two of its next generation x86 processor cores, codenamed Bulldozer and Bobcat.

The newly revealed two core designs are meant for high end PCs and servers, and low power notebooks and small form factor PCs respectively, and have been created from the ground up, according to AMD, to meet the requirements of specific form factors and usage models.

The Bulldozer core is  built on 32nm technology, which includes advanced power management features, and has been designed to balance dedicated and shared compute resources, for highly compact, high core count processor designs, along with new x86 instruction support (SSE4.1, SSE4.2, AVX, and XOP including 4-operand FMAC).

The newly revealed Bobcat core is designed specifically for small mobile devices, and is capable of providing 90% of the performance of mainstream PC performance in half the area of silicon, according to AMD. The core power gating and microarchitecture are optimized for low power, enabling sub-one watt operation, along with out-of-order instruction execution for higher performance.

“In my opinion, Bulldozer and Bobcat are not only two of the greatest technical achievements in AMD’s rich history, but two of the most important for the industry as well,” said Chekib Akrout, senior vice president and general manager, AMD Technology Development

CCNP SWITCH 642-813 Official Certification Guide- a new suppliment available

Yasir Irfan Yasir Irfan Profile: Yasir Irfan


All CCNP Certification aspirers, who ever have purchased CCNP SWITCH 642-813 Official Certification Guide new supplement content is available to cover up the additions made to the Cisco Switching Exam 642-813 after the above mentioned title was mentioned. You can directly download the additional contents from the Cisco Press page –look on the catalog page under “Updates”.

I went through the supplement content “How to prepare for the Planning Topics on the Exam”. The new supplement replaces the current content in the page 13 of the title CCNP SWITCH 642-813 Official Certification Guide. It deals with how to prepare for the planning topics on the exam, when compared to the book I could notice some changes, Cisco is emphasizing on the CCNP certified professionals to know more about planning and documentation ,though the exam might not directly test you to create a plan.  But the supplement does guide you to come up with an implementation plan, it deals with the business requirements, business constraints and technical requirements.

Cisco expects you to be aware of creating plans for implementing a network, and you may get a scenario, based on the scenario you are supposed to figure out what specific features you’ll need, what steps you’ll need to configure for each feature, which switch you’ll have to visit to type in configuration commands, and so on.

Even as you work through a scenario on the exam, you should spend time creating a verification plan so you can test and make sure each feature you have configured actually works as it should. Otherwise, whatever you typed into the switch emulators might not be correct and might not earn you valuable points.

Do download these additional supplements which are quite useful for the CCNP aspirers.
