Study Tips – Retain What You Read

April 1, 2018 at 5:20 pm

Study Tips

Most of us spend at least some of our study time for the next great IT Certification reading from books, whitepapers, or online documentation. But how effective this process is depends on how much we retain! Here are some tips for retaining more as you read!

  • Stop and reflect – just read some really important facts about a technology? Look away from the material and really think and reflect on it. This will help retention immensely. It is something we often forget to do because we are typically trying to study as quickly as possible.
  • Repeat, then repeat – consider drills, flash cards, or exercises, and consider doing them over a nice long period. Most recommend repetition over long-stage, spaced intervals to keep information fresh. Reinforcing new concepts every week or two helps it become known facts.
  • Create a catchy word or phase – the famous All People Seem To Need Data Processing or Please Do Not Throw Sausage Pizza Away is so famous because it works! One I learned from Keith Barker is the Port Security violation modes in Cisco networking. I always struggled to remember which one did not log and violations and was not recommended by Cisco. He taught me to just remember them in alphabetical order. P – R – S. Protect – Restrict – Shutdown. I never forgot that Protect is the lame one again as that order also reflects action severity!
  • Remove distractions – the ping of a cell phone, a desk photograph, music, e-mail – and of these might take you out of the zone you want to be in while reading!
  • Make connections – try and tie what you learn into other facts that you have memorized. The OSI Model is a great example of this as you can place new technologies in their appropriate layer and make connections with surrounding technologies.
  • Prioritize what counts – as you are reading, constantly reflect on what the most important information is so you can really focus on that!

Cisco – Migrating from STP to RSTP

February 11, 2018 at 8:05 pm

CCIE

A frequent CCIE-level written exam topic is STP (PVST+) to RSTP (Rapid-PVST) migrations. This post covers the high points you should be aware of.

Some Quick Notes

  • BackboneFast and UplinkFast are no longer necessary in RSTP environments as the equivalent advantages are built-in to RSTP
  • BPDUs are version 2 in RSTP which is compatible with version 0
  • All ports now send BPDUs and they act as a keepalive mechanism
  • The new port roles are designated, root, alternate, and backup
  • The new port states are forwarding, discarding, and learning
  • The new port types are shared, edge (PortFast), and P2P
  • When an RSTP port receives a legacy BPDU, it reverts back to compatible behavior and performance enhancement benefits are lost
  • BackboneFast is configured on all switches in order to function in STP and UplinkFast is configured on access layer devices

Migrating

  • You are not forced into removing the BackboneFast and UplinkFast commands – if they are left in place, they do not impact the operation of RSTP
  • Removing the Uplinkfast command impacts the bridge priority and port cost values, so be sure you consider this
  • CatOS (FLASHBACK!) does not permit the BackboneFast command within RSTP so you must remove it in that legacy case
  • Plan a phased migration and use a maintenance window as traffic flows can be impacted
  • The configuration of the features such as PortFast, BPDUguard, BPDUfilter, root guard, and loopguard are applicable in rapid-PVST+ mode also
