CCNA

I've just completed my first CCNA training as a teacher.
Two weeks, ICND1 and ICND2

The course is much better, it's changed for good since 2006.

I liked very much L2 and L3 sections, very good explanations and pictures/slides, step-by-step examples.

It's still Frame-Relay there.... i wonder if it's still in use now, thanks God no IPX anymore, and very good IPv6 section

I didn't like the LABs. They are supposed to be used in a way when students do not see the devices, and use remote connectivity to manage remote devices.

So, i refused to use the proposed remote laboratory  and grab some devices i could find out-of-use in my work.

I've got a 3640, one 2811, a few 2960s, one 3400, a  2600, and 7200 in dynamips for some tests.

Good mix of routers/switches, one L2-L3 switch.

So, in  about 10 days my students had a chance to get a real experience - password restore, device connectivity, terminal cable connection and console program setup/use, IOS upgrade, an so on. We disassembled the 2600 (likely it's failed because one memory bank unlocked) and managed to restore it to normal operations, could see how the thing does NOT pass boot testing.

Yes, it's the same LABS as proposed in the course, BUT - it's real hands-on experience, which is very important, from technical and psychological aspects.

So, on the day 10 people who didn't even understood OSI levels  where pretty comfortable in setting up/running devices, ip stack, advanced switching features, NAT (via CLI), RIP, OSPF, EIGRP, and even some redistribution functions,IPv6 basic routing.

We also spent half a day 9 implementing their labs - they brought their ideas, tasks, real life challenges and we've solved them all.

I wanted to try myself in a teacher role, and i think it went very good.
The best measurement - a can hardly remember when students asked to go to a lunch or have break or being bored/tired.
