Resetting Cisco IOS configuration
July 17th, 2006
You can use the following Cisco IOS commands to reset the Cisco configuration back to factory defaults:
write erase
This will clear the startup-config and fill it up with factory defaults.
delete flash:vlan.dat
Most Cisco IOS switches keep VLAN configuration data — like VTP protocol data, active VLANs, and so on — in flash memory, in a file called vlan.dat.

Wow just a bit of the old “crazy” in here today. Didn’t take long.

For problem-11, shouldn’t it be 305,000?
