It has been a while since my last post. Let me show you why.
As I said in a previous post, this ain't easy. Five people out of 20 didn't pass the last test. The next test, tomorrow, 10 people aren't even going to attempt. This next test is a switching test. How hard can switching be? :)
If the only thing that someone is familiar with is 2 or 3, or even up to 100 computers/devices, switching is pretty much easy. Plug it in and turn it on. You don't have to worry about BPDU's, spanning tree loops, DHCP snooping, or any of the 100's of other issues that could happen. Once you get into the 100+ devices or multiple locations, layer 2 and layer 3 routing, and all the appropriate paths REALLY become an issue. What about Access Lists, Dyanmic NAT overload, EIGRP Stub and Sotally Stubby, or the Totally Not So Stubby routing protocols with summary addresses. Maybe routing protocol redistribution from OSPF into EIGRP. Now some may say, "But Tom, this is ROUTING!" A HA! Not layer 3 switches with InterVLAN routing. :)
In the long run, I do this all to be able to provide the very best to the Campbellsport School District.
As you see from the picture, I have my computer on. While I have been studying, and literally in class from before sun-up until after sun-down, and then usually until past midnight, I have been working remotely. Granted, I haven't been doing ALL of the same things I would have been doing if I didn't have to study for the tests, but I still have been doing a lot. I just compared all the code that has been changed on all the switches and routers since I have been gone; over 1500 lines of code changes!
And, for you techies, my most popular thing to type has been, "reload in 30" :) (This will reload a device in 30 minutes and restore the previous working config if what I type was bad).
Going to be a long night tonight.
Tom
