How a Cisco SE Navigates Cisco.com

At the time that I’m writing this I’ve been working at Cisco for just over 3 years as a Systems Engineer. Prior to that I worked for multiple Cisco customers and was heavily involved in Cisco technologies. I know what a monster cisco.com is and how hard it can be to find what you’re looking for.

Since starting at Cisco, the amount of time I’ve spent on cisco.com has shot up dramatically. Add to that studying for my CCIE and it goes up even more. In fact, cisco.com is probably the number 1 or 2 site I visit on a daily basis (in close competition with Google/searching).

After spending all this time on the site and given how vast the site is and how hard it can be to find that specific piece of information you’re looking for, I’m writing this post as an aid to help other techies, like myself, use the site more effectively.

OS X – Outlook Search “No Results”

The worst feeling for a geek:

This has happened to me twice now: upgrading Mac OS X from one release to another and after the dust settles, the search function in Outlook 2011 totally breaks and always returns “no results”. As we all know, email sucks and being able to deftly search through that mound of crap in your mail client is the only thing that makes it somewhat bearable.

Role Based Access Control in IOS

I don’t believe this is well known: Cisco IOS has Role Based Access Control (RBAC) which can be used to create and assign different levels of privileged access to the device. Without RBAC there are two access levels in IOS: a read-only mode with limited access to commands and no ability to modify the running config (also called privilege level 1) and enable mode with full administrative access. There is no middle ground; it’s all or nothing. RBAC allows creation of access levels somewhere between nothing and everything. A common use case is creating a role for the first line NOC analyst which might allow them to view the running config, configure interfaces, and configure named access-lists.

CCIE R&S – By the Numbers

When I started studying in earnest for my CCIE, I started a log of how I was spending my time studying, which books and papers I’d read, videos I’d watched, and so on. I thought it would be a neat exercise to look back afterwards at what it took to achieve this goal. I’m also somewhat self-deprecating and tend to minimize my accomplishments, so having this data is a way for me to remember that this wasn’t a small accomplishment at all.
