CDP Timers Plus Another Use For The “Default” Command

Filed under: Cool Commands,IOS — cciepursuit @ 4:17 pm

I was doing some ODR routing labs today and started mucking about with CDP timers (ODR uses CDP for advertisements).  This is important to note in case you get a task that requires you to change the convergence time of an ODR learned route.  CDP timers are changed at the global level.  The default values are 60 seconds for advertisements with a 180 second holddown time.

How to change CDP timers (must change timer(send) and holdtime separately):
sw4(config)#cdp ?
  advertise-v2  CDP sends version-2 advertisements
  holdtime      Specify the holdtime (in sec) to be sent in packets
  run           Enable CDP
  timer         Specify the rate at which CDP packets are sent       (in sec)

sw4(config)#cdp timer ?
  <5-254>  Rate at which CDP packets are sent (in  sec)

sw4(config)#cdp timer 5
sw4(config)#do sh cdp
Global CDP information:
        Sending CDP packets every 5 seconds
        Sending a holdtime value of 180 seconds
        Sending CDPv2 advertisements is  enabled

sw4(config)#cdp hold 15
Global CDP information:
        Sending CDP packets every 5 seconds
        Sending a holdtime value of 15 seconds
        Sending CDPv2 advertisements is  enabled

Here’s some weirdness: you can configure the holdtime to be less than the update timer:

sw4(config)#cdp timer 30
sw4(config)#cdp hold 10
sw4(config)#do sh cdp
Global CDP information:
        Sending CDP packets every 30 seconds
        Sending a holdtime value of 10 seconds
        Sending CDPv2 advertisements is  enabled

To set the CDP timers back to the defaults, you could manually set the “timer” value to 60 seconds and the “holdtime” value to 180 seconds, but let’s use the “default” command to return the timers:

sw4(config)#default cdp timer
sw4(config)#do sh cdp
Global CDP information:
        Sending CDP packets every 60 seconds
        Sending a holdtime value of 15 seconds
        Sending CDPv2 advertisements is  enabled
sw4(config)#default cdp hold
sw4(config)#do sh cdp
Global CDP information:
        Sending CDP packets every 60 seconds
        Sending a holdtime value of 180 seconds
        Sending CDPv2 advertisements is  enabled

Sweet!  I love the “default” command.

Most Popular CCIE Training Materials

Filed under: CCIE Lab Workbooks,Cisco Certification,Training Materials — cciepursuit @ 10:22 am

I had planned to blog about the materials that I believed to be the “Gold Standards” (by way of popularity) of CCIE preparation based on feedback in various CCIE forums.  I then decided to be a little more “scientific” about my results by finding posts by people who have recently passed the Routing and Switching CCIE lab and documenting what materials they used to study for the lab.  I went back through Group Study’s CCIE archive (as well as the Sadikhov CCIE lab forum) and pulled out the posts by folks who passed from January to June of this year.  I kept all of the posts that listed the materials that they used in their preparation.  I then put all of this information into a spreadsheet to analyze the results.

In the end I had 36 posts by people who have successfully passed the CCIE R&S lab exam over the last 6 months and bothered to post what study materials they used.  I have broken the material up into the following categories: Workbooks, Bootcamps, Mock Labs, Video Training, Technology Focused Labs, and Other Materials.

Here are the results:

Caveat Lector: This is not meant to be a comprehensive survey by any means.  There were also a few posts that were nonspecific about the actual product used.  I did not include any cases where the vendor was not specified, but if I ran across something like “I used material from IPexpert, IE, and NMC”, I counted that as an endorsement for the workbook of each listed vendor – although that may not have been the “material” that was used.  As mentioned before, I only counted posts that were from people who had passed the lab exam and posted what materials they used.  I am sure that I also missed a few posts.  Although Group Study is a very popular forum (actually it’s a mailing list) I am sure that there are plenty of people who have passed who have not posted their success there.  :-)  Finally, I have listed the links to the entries from which I pulled the data. For comparison, here was what I originally was going to post before pulling this data:

What I Did To Pass The Ccie Lab (Sadikhov CCIE Lab Forum – Multiple Passes)
http://www.sadikhov.com/forum/index.php?showtopic=67385

Soup-to-Nuts-to-???

Filed under: CCIE Lab Workbooks,Training Materials — cciepursuit @ 8:28 am

One of the training books I am considering purchasing is the CCBootcamp(NLI) Soup To Nuts workbook.  One of my co-workers (who is prepping for his 3rd lab attempt) swears by it and is using it to shore up his weaknesses for his upcoming lab attempt.  The workbook is available only in printed format and is pretty spendy ($695).  Maybe I should be using the past tense as the Soup To Nuts workbook has disappeared from CCBootcamps website.

It looks like they are releasing a new product called “NLI’s Cisco CCIE R&S Lab Technology Workbook” to replace the Soup To Nuts workbook:

NLI’s Cisco® CCIE® R&S Lab Technology Workbook
Book Content Outline

COMING SOON!

  • Multiple, in-depth, technology based practice lab scenarios.
  • Extensive step-by-step analysis and explanations for the configurations required to complete each lab.
  • No need to purchase expensive add-on guides that provide step-by-step analysis. This is a complete product.
  • Designed around our standard rental rack configuration.
  • Completely up-to-date and designed around the current CCIE® R&S Lab Exam.
  • 12.4 features included.
  • Initial and final configurations available for download.
  • Extensive product support at our very popular discussion site www.routerie.com with 20000+ users.
  • Click here to download a sample lab with solution – Coming Soon!

The content looks similar to the Soup To Nuts workbook (archived link).  I am guessing that CCBootcamp is updating the material and renaming the product.  The meaning of the original title might have been a little too obscure for most (myself included):

“Soup to nuts” is an English idiom conveying the meaning of “from beginning to end”. It is derived from the description of a complete meal, whose courses range from soup to a dessert of nuts. It is comparable to expressions in other languages, such as the Latin phrase ab ovo usque ad mala (“from the egg to the apples”), describing the typical Roman meal. It was originally used by D Ryan in the 18th century and has carried forward to our modern times.

Anyhoo…I will look forward to the new release.  I am still undecided as to whether or not I want to drop $700 on it though.  I still have a ton of material to work through before I even consider it.
