Cisco Announces Changes to CCNP
It's almost like those too-familiar infomercials that get so popular around New Year's - time to get rid of the fat and add some muscle. Cisco's done the same to CCNP with today's announcement of CCNP changes. Cisco starts by removing roughly half the topic breadth from the old CCNP: most every topic from ONT and ISCW is gone. Cisco then adds back a Troubleshooting exam that focuses on routing and switching with a few other topics. Today I'll begin an examination of this revised cert, with lots of links, some impressions, and a promise to more time in the coming weeks drilling down on the new exams.

CCNP track will be changing later this year
Cisco has made it official - the CCNP track will be changing later this year, and you have over *six months* to take the current exams!
You can take the BSCI, BCMSN, ONT, and ISCW exams all the way up to July 31, 2010 - and the current BSCI and BCMSN exams count on the new track!
Therefore, it's vital for you to get those first two exams done before the deadline - and it's certainly more than possible for my Bulldogs out there to get all four done in the next six months!

Topology Design for Routers Through the Lens of a Lab Exercise
Do you need two routers to practice routing commands for CCNA? Or do you really need 3 - or even 4? Likewise for CCNP, or one of the CCNA concentrations? And what topology do you need to use - which determines what interfaces to buy - so that you can test every function of every config option for that exam, and see the nuances that you might miss in a different topology? And what are those nuances in the first place? And what lab exercises should I use to learn all this? Well, you asked for it, and I liked the idea, so I'll blog it: some lab exercises that at the same time give us a backdrop to discuss lab topologies.

Ship sails with Cisco wireless
Nine hundred Cisco access points are allowing Royal Caribbean Cruise Lines to navigate the tricky waters of wireless at sea. As colleague Tim Greene reports, the world's longest cruise ship presented plenty of churning tides for a network encased in the steel hull of the vessel.

Spanning Tree Protocol and Failure Domains
Co-worker Pete Welcher recently helped a customer whose network experienced a spanning tree loop (i.e. a melt-down). Several things can be learned from thinking about the experience and how to avoid it.

Configuring Virtual Switching Systems
Looking to install VSS ? Well, recently I had the opportunity to install VSS in a customer’s Data Center as part of a complete network migration from an old Nortel Switch network to a new Cisco network using primarily Catalyst 6509 switches with Sup 720 – 10 G Supervisors.

Dear Hiring Manager:
I am seeking employment opportunities in the field of Cisco network engineering.
My career objective is to continue to study for Cisco certifications while working on production Cisco networks on the job.
I obtained the CCNP certification on July 24, 2011.
Since September 2008 I have been working as a Network Engineer for Sprint in Reston, Virginia. A description of my current job can be seen here.
For the ten years prior to that I was working for Sprint in the Broadband Access Delivery circuit test and turn up group in Atlanta, Georgia. There I performed physical layer testing on circuits ranging from DS3 to OC768. Mostly SONET transport network, some DWDM. Extensive use of T1 testing, narrow-band DACS, wideband DACS and broadband DACS. React test set. Loopback and acceptance testing with LECs.
See resume here.
Around October 2007 I started getting interested in Cisco certifications and the Cisco certification career path. I began to attend the Atlanta Cisco Study Group meetings in Atlanta, Georgia.
A couple of Cisco router engineers from Reston, Virginia came to Atlanta to provide some IP Activations training and I was fortunate to be able to attend those classes for 3 weeks.
Shortly thereafter, in August of 2008 I took an opportunity to work with the IP Network Activations team in Reston, Virginia near Washington, DC.
I have been working as an IP Network Activations engineer with Sprint/Nextel/Ericsson at the Reston, Virginia NOC since that time.
Here in Reston I am a member of the Cisco Mid-Atlantic User Group and Cisco IP Telephony User Group.
If you are an employer who's business revolves around Cisco IP routing and switching networks then I would be interested in talking with you.
I am interested in all of the Cisco tracks and would be willing to study whichever track is needed. Company paid training and company assisted training programs, along with the opportunity to work on cutting edge technologies with senior level Cisco Network Engineers and CCIE's, are my highest priorities.
What I bring to the table has been noted above along with an above average focus and propensity to study and learn Cisco routing and switching technologies.
Thank you for your time and consideration.
Sincerely,
Doug Kenline

Duplicate ASN Numbers
Organizations need an ASN to run BGP and route on the Internet. They are each assigned globally unique ASN(s) by their local Regional Internet Registry (RIR), who get them from IANA. A few weeks ago, the NANOG folks noticed that AS1712 had been registered by two different organizations (in France and Texas) that were both using the number to announce their separate network prefixes. ARIN issued a statement conveying that they were aware of the problem and were working to resolve it. We took a look at the data and found that AS1712 isn't the only dually-assigned ASN out there. In fact, even a root server didn't escape unscathed.

ISCW Down, Three To Go
I took and passed the ISCW test today. I was super-nervous going into it, which is weird for me, but I finally calmed down after the first few questions. Here’s my take. I don’t want to get into any trouble so I’m not going to include very much detail.

Explaining Etherchannel
This blog post will explain you all the differences in EtherChanneling that you can get. It’s known that you can get any type of wicked configuration on the R&S lab, especially since there are 4 switches, which are probably fully meshed with multiple links.
Why?

I have a Cisco 2500 router and I can't get it to boot up. It was working fine and now all of a sudden it won't boot up. I saw it go in to rommon> mode and then I just rebooted it and now it gets stuck on boot up.
I tried to hit ctrl-break to get into rommon mode within 60 seconds of powering down and back on. It gets the > prompt but no response from any keys at that prompt.
Anybody have any ideas. I think the router is shot and is now hazerdous waste.
click to imbiggen.
I think this is the message that might have a clue in it.
%SYS-4-CONFIG_NEWER: Configurations from version 11.2 may not be correctly understood.
This is what it looks like if I don't hit ctrl-break to try to get in to rommon mode. It's gets this far but no farther. It gets stuck right here.
Also posted at PacketLife community lab forum here.
Update: Now it's working. Never mind.
