If a switch gets rebooted and the settings haven't been "wr"d, when it comes back up things will be all wrong. I want to see what the current vlan settings are vs what has been "wr"d.

Thanks!!

Edit:

Er... I meant like the difference between current show int status and what will get set if the switch gets rebooted. Thanks!

Show running-config vs. show startup-config. As long as the switch is in vtp transparent mode the vlan info will show up.
