Walt Disney is one of my personal heroes, and the following quote from him beautifully sets the stage for this blog post’s topic, curiosity:
We keep moving forward, opening new doors, and doing new things, because we’re curious, and curiosity keeps leading us down new paths.
– Walt Disney
Curiosity about how something works spurs on mastery of that topic. It motivates us to want to learn more. This blog post examines some of the benefits of having a healthy curiosity, steps to further develop your curiosity, and another tale from the trenches that illustrates how curiosity led to the development of one of my most popular Cisco training videos.
Albert Einstein said, “The important thing is not to stop questioning. Curiosity has its own reason for existing.” Are you curious how curiosity can help us in our Cisco careers? Let’s consider just a few benefits of curiosity.
At this point, you’re hopefully sold on the concept of curiosity being a very positive characteristic to have as a Cisco professional. This then leads to the question of how we cultivate a stronger curiosity within ourselves. Here are a few tips:
Let’s further assume that they are each assigned to troubleshooting a Spanning Tree Protocol (STP) issue in their network. Who do you think will ask the more effective troubleshooting questions?
The engineer who had been studying on their own time might look at the issue and be curious about which switch in the topology is acting as the root bridge and about the bridge priority of that switch.
The engineer who had not done as much independent study, might ask less effective questions. While they might be curious as to why the network wasn’t working correctly, their level of curiosity is constrained by their lack of understanding about the operation of STP.
The conclusion that we can draw is that the more we know about a technology, the more curious we become and the more effective questions we can ask.
Being a traditional teacher, standing up in front of a class, is not in everyone’s DNA. However, there are other ways to teach what you know. You can teach somebody one-on-one. You could write a technical white paper, or record a video tutorial. Whatever way best suits you, I encourage you to teach.
For example, you might curiously ask yourself, “What convergence time would I get if I reconfigured the Hot Standby Router Protocol (HSRP) Hello timer on my routers.” If you had a test bed environment, you could duplicate a portion of your production network and quickly determine the convergence time. This could then lead to the next question, and the next, and so on.
While studying for my second attempt at the CCIE Voice lab, one of the technologies on the lab blueprint that I (and many other lab candidates) found most challenging was Quality of Service (QoS) configuration on Cisco Catalyst 3750 Series switches.
After reading through the Cisco docs, whitepapers from CCIE training companies, and doing practice labs, I still didn’t completely get it. For example, the way Shared Round Robin and Shaped Round Robin worked was very confusing and unlike any other Cisco technology I’d ever seen.
I’d been creating YouTube training videos for some time, and I decided that what the industry needed was a comprehensive training video on Cisco Catalyst 3560 and 3750 QoS. Not only would creating such a video fill a need in the training space, it would force me to learn the technology such that I could explain it to others.
So, I got incredibly curious about all aspects of QoS on these switches. I would dissect the Cisco documentation and rewrite what I was learning, in my own words. The result was a 1 hour and 45 minute video entitled Cisco Catalyst 3560 and 3750 QoS Simplified… Seriously! This video has since become the most popular videos on my YouTube channel and has helped many CCIE R/S and CCIE Voice/Collaboration candidates get a better handle on this challenging topic.
