Cisco Newbie Help with L2 and L3 Devices

In a phone interview, you should be going off your own knowledge.

However, as a clue, you might want to do some research on subjects such as:

- Virtual LANs (VLAN)

- VTP (VLAN Trunking Protocol): VLAN database revision numbers especially, when you are adding a new swich to the network!

- Routing protocols

Then again, if you don't actually understand what you are talking about over the phone, then it will REALLY stick out! :-)

Cheers, I've not had the chance to add a new network device yet, just some support!!

Thanks for the info!!!

I will echo the VTP answer, as that is the one area that will bring down your whole network if you don't know what you are doing. The rest of the answers are things to do/check to make sure your install is prepared correctly and goes in smoothly without last minute changes and on the fly configuration.

management IPs vtp domains/revision trunking configurations

And on the routing side, routing protocols, addressing, configurations, summarization, route-maps, etc.

SPANNING TREE!
