If one stays long enough, the law of averages will invoke. It's natural in a way, every industry and companies, like life in general, has issues.
Stick to your core competencies that you demonstrated to get hired in the first place, and don't forget how to utilize and develop them to grow yourself.
Cisco is like a natural ecosystem, and it's now in the part of its lifestyle where there is ample room for many layers of management; many times perhaps driven by people who are skilled at taking full advantage of those opportunities.
If you aren't geared like that, don't try to be, focus on using your core skills to do the best you can; but don't sell out and completely buy in...remember who you are. There are many places for philosophies of the non-political worker who wants to focus on the technology and process...either it works or it doesn't...and if it doesn't...get it to work.
I miss working at Cisco but once I lost that personal connection to owning simple true functionality ownership, in a way I lost a big portion of what empowered me to be successful and thrive.
I sold out in a way because the money was good, and I explained away my own common-sense, that I really no longer was in a scenario to demonstrate my core skills.
Keep fully aware to be enabled to truly perform at providing your core skills; and if you can't, try to make sure you don't truly forget who you are.
It's a big world out there, lots of opportunities. Just keep growing yourself.
