My CCIE Lab experience

Filed under: cisco, Technology and Software — ciscotips @ 10:10 pm

I was all geared up for my CCIE R&S lab in san jose.  I was a bit nervous as most of my lab practice came from job experience, plus some online workbook scenarios. Not to mention that I relied more or less on a non-conventional style of study. Dynamips was definitely a great help especially if you are running your dynamips on UBuntu Linux ( I love it).

I arrived in San Jose 2 days before my lab, and tried to manage my stress and jet lag. I promised myself that I would not look back in to my notes, but guess what i was so stressed that I started looking back in to my Qos,multicast and IP securtiy notes. I tried to have a good night sleep before the exam, but I was not able to sleep. I was getting cisco dreams all night.

I woke up at 6:30 in the morning and got ready for the exam, I had a yogurt for my breakfast as it was my wife’s suggestion. Arrived at site, checked in and the front desk guy asked for my ID, then he checked  me in with other candidates waiting in the lobby. I could see some going through notes and other just confused and lost. Proctor arrived at 8:15 and he acquainted us with rules and regulations.

by the lunch hour I was pretty confident as i thought I was doing well but right after the lunch I had some doubts, I skipped a few questions and moved on to the next. I finished rest of the tasks and the time was already 4:30. 30 minutes to go and i had still few tasks left which i had skipped earlier. I went back to the tasks and tried to finish all of them. By the time I finished all the tasks , my time was up.

I came out still confident and with a great hope that I would clear the lab. I was awake again whole night as the proctor told me that I would get a result the next morning. I checked my mail almost three times in the night but nothing fruitful came out of it. In the morning at almost 7:15 AM, I checked my mail again and I could see a mail from cisco. I logged in to Cisco with my CCO id, my heart was beating fast. To my surprise, I could see FAIL next to my score. What went wrong , I asked myself. My technology score was black and white enough to show me where I messed up.

For my secont attempt, I’ve signed up for Narbik’s bootcamp in June, and am planning to retry my lab within a few weeks of completing the bootcamp.

Grep for Cisco commands

Filed under: cisco — ciscotips @ 6:52 am

To view a IOS line parser

Show parser dump

Its an excellent command to see the selected functionality of the command. we can use it just like a Grep in Unix.

 For example:

R1#sh parser dump interface | include queue
15 tx-queue-limit Number
15 dialer hold-queue <0-100> timeout <1-2147483>
15 dialer hold-queue <0-100>
15 dialer hold-queue
15 funi rate-queue Number Number
15 funi rate-queue tolerance svc pvc 0 strict
15 funi rate-queue tolerance svc pvc 0
15 funi rate-queue tolerance svc pvc <5-99> strict
15 funi rate-queue tolerance svc pvc <5-99>
15 funi rate-queue tolerance svc 0 strict
15 funi rate-queue tolerance svc 0
15 funi rate-queue tolerance svc <5-99> strict
15 funi rate-queue tolerance svc <5-99>
15 funi rate-queue Number Number
15 funi rate-queue tolerance svc pvc 0 strict
15 funi rate-queue tolerance svc pvc 0
15 funi rate-queue tolerance svc pvc <5-99> strict
15 funi rate-queue tolerance svc pvc <5-99>
15 funi rate-queue tolerance svc 0 strict
15 funi rate-queue tolerance svc 0
15 funi rate-queue tolerance svc <5-99> strict
15 funi rate-queue tolerance svc <5-99>
15 funi rate-queue Number Number
