In its most recent Form 10-Q filing (page 36) with the U.S. Securities and Exchange Commission, Cisco fretted: "In the second quarter and the first six months of fiscal 2009, our gross margin percentage decreased compared with the corresponding periods of fiscal 2008. "The decrease was driven by lower product gross margin, which was due to higher sales discounts and rebates." What's the identity of one of the culprits? Michael Morris From the Field: NX-OS Training Videos on YouTube
Since we've been on a Nexus switch track over the last couple weeks, first discussing the highlights of our Nexus Data Center design and then Virtual Port-channels (vPC), I thought it would be a good to share some NX-OS training videos that are on YouTube. Jamey Heary: Cisco Security Expert: Obama’s Electronic Health Records initiative could usher in a new wave of ID theft
With the stimulus bill all but signed it looks like the government will be handing out $19 billion in an effort to digitize America’s health record system. The problem is we have a noble goal but no plan or direction on how it should be accomplished. The stated goal, which has garnered substantial support, is to build a National Electronic Health Records (EHR) system. But the plan or direction on how to get us there is completely missing from the stimulus bill. When the government throws lots of money at a problem before they have a viable plan or even the framework of a plan in place disaster usually strikes. Reference the recent Tarp disaster for proof. Given the current stimulus bill’s ambiguity it looks like we are destined for yet another misuse of funds, this time with modernizing healthcare. Wendell Odom's Cisco Cert Zone: OSPF Puzzle V: Predicting Which LSAs are in Which Areas
Yikes! Of the 10 answers in 2 different questions last post, we've got at least a handful of choices for 9 of the 10 - and the answer that no one chose is actually a correct answer! I'll take that as confirmation that there's at least enough confusion on this topic as to be a useful discussion for those going after the CCNP routing test. And, it seems like for those that offered an opinion, there's no big difference in difficulty on the LSA questions that are mostly theoretical versus those that relay on variations of "show ip ospf database". So, I'll cover both styles, focusing on the more theoretical view of OSPF today. Larry Chaffin: Putting the realism into your network:"Change we can count on" with Obama Cyber Security Review. Kidding people....
Well president Obama ordered his National Security and Homeland Security advisors Feb. 9 to conduct an immediate review of the U.S. government's cyber-security plans, programs, and activities. The person heading the 60-day review will be Melissa Hathaway, who served as the cyber-security coordinator executive under Mike McConnell, former President Bush's Director of National Intelligence. Dennis Hartmann on Cisco Unified Communications: Cisco QoS - LLQ / CBWFQ and MQC Processing
In the past couple of blogs, we investigated the MQC, CB-WFQ, and LLQ. Since you’re familiar with the MQC policy-maps now, let’s discuss some details of the system. Similar to an access control list (ACL), a policy-map is processed by the router in a top down fashion. Each class is evaluated in the order they were put into the policy-map and the last class in the policy-map is always the class-default. The class-default is in every policy-map by default and it cannot be removed. The class-default has a classification policy that matches all traffic that has not been identified by any other class in the policy. Jimmy Ray Purser: Networking geek to geek: JTAG Hacking
One of my neighbors knocked on the door yesterday. I figured he wanted to borrow some tools or wanted me to fix his computer because he came over with a six'er of Newcastle. I think Dr. "Bones" McCoy said on Star Trek IV, "Beware of Romulans bearing gifts..." And English Ale beats the crap out of Romulan Ale any day! Come on in!!! Turns out, he was updating the firmware in his home router and accidentally kicked the power cord out of the router in the middle of an update. Can anything be done? I stalled for time until the last Newcastle was gone and then said maybe we can JTAG it. Author Expert: Brandon Carroll: EIRP in a nutshell
