Airports and Delays

I hate connecting flights. My flight from Newark to Austin is via Chicago. The first leg, no problems. The second? Well that’s another story. Flight is delayed nearly two hours because United can’t find a First Officer. His flight into Chicago is delayed. And now begins the domino effect of problems and frustration. Oh well, this too shall pass! Luckily I’ve got plenty of electronics to keep me occupied, aside from some snacks and beverages.


Cisco Nexus 3000 and VTP

If you want to use VTP on a Cisco Nexus 3000 series switch, you can just forget it. They only support transparent mode. That’s only useful if you have a VTP server somewhere else. I don’t understand why Cisco doesn’t support server and client modes in the 3000 series, especially when they support SVI. It’s not a license issue either. Cisco TAC confirmed this all, and the engineer that I spoke with is just as confused by all of this. Moral of the story is, don’t use 3000 series switches as your core layer if you wish to have them manage VTP. Oh well, my loss is your gain.


CCNP Security, Half Way There!

Last Friday, I took the second of four tests to complete the CCNP Security certification. And I passed! Cisco is changing the tests on April 21 this year, so I’m not sure if I’ll be able to cram in two more tests by then. I won’t lose any credit of what I’ve done so far, but all the testing material will become obsolete by then.
