I shake my head around sometimes and see what falls out. That's what lands on these pages.

QoS Notes – IPP and DSCP Values

Back in the day, somebody decided that we all needed to have a Type of Service (ToS) field in the header of IP packets. Only God knows what this spawn of Satan wanted to do with it, but we’re stuck with it on the CCIE R&S exams. Can you tell I hate QoS?

CCIE R&S Written – Epic Fail (Again)

Yes, I failed. I think it’s pretty typical when you’re at Cisco Live, stay out drinking and smoking cigars until 1am, then sit the exam at 8am. Considering the situation I put myself in, I wasn’t very optimistic about the exam. I figured maybe a 40% chance I would pass since I didn’t really even study.

Cisco Live 2013 Insights – Catalyst 3850

Cisco Live is obviously the biggest networking event of the year, and Cisco likes to use all the attention to show off some of their new gear. I must say I was impressed with the Enterprise offerings including the 6807-XL, the 6880-X, the 4451-X, and the Sup 8-E for the 4500-E. Those boxes definitely gave me a bit of a tingle when I was checking them out, but my eyes opened up when I saw the 3850. The Catalyst 3850 is the next version of the 3k line of switches and the successor to the 3750-X.

Cisco Live 2013 Insights – Cisco Tactical Operations

While walking through the World of Solutions, we ran across a big black truck with lots of antennas all over it. It was obviously an emergency communications vehicle of some kind, but I was really surprised to see it was a Cisco truck. It turns out that Cisco has a Tactical Operations group that was formed to provide disaster responders with much-needed communications for FEMA, state EMA, fire, police, medical, etc.

JNCIS – Epic Win!

I quit my job…by design.  I start a new gig on Tuesday and am getting back to the world of Cisco.  As a last nod to Juniper, I decided to use an exam voucher I had and take the JNCIS-ENT…
