Narbik’s Bootcamp – Day 5 (QoS etc)

We started the day with 3550/60 per-port per-vlan QoS and then moved on to mls qos. Narbik talked about Policers, IP Prec, DSCP values and went in detail to show us how IP Prec and DSCP values are derived. He went over Priority Queueing, Custom Queueing and explained the issues with those. According to him, the problem with PQ was that if you had more traffic in the queue higher than yours, then your queue will always starve.

He explained MQC aka CPS (Class-map, Policy Map, Service Policy). Its amazing how he can spit the options after ever "?". I even tried to double check so I can pick on his mistakes but didn't happen.

We covered Marking, CBWFQ, LLQ, Class-based compression, Filtering, CAR, Class-based policing, Random Early Detect, Frame-Relay traffic shaping, Class-based shaping etc.

His QoS lecture was amazing and one of the guys who was attending this 2nd time said this was totally different from last time and he picked up so much more stuff this time around. So basically his lectures are different EVERYTIME unlike some vendors that go over the power points and you can be sure to see the same material doesn't matter if you attend their bootcamp after a month or a year.

At the end of the lecture he provided some tips for the actual lab and recommended that we reattend his class before we attempt the lab.

My overall reaction to the bootcamp is that I WISH I had this opportunity earlier right after I passed my written. I know Ethan did the same mistake where he wasted his time fooling around with different things before finally attending Narbik's class.

Well it's never too late so I am glad I got to talk to Ethan and booked Narbik's class. I am planning to reattend his class on Aug 11th 2008 in Pasadena, CA. My plan is to finish all his workbooks before then and go in the class wellprepared. If you have ANY questions about my experience, feel free to contact me.
