Cisco IOS port configuration?
Is there a difference between using the disable option and the 'no' option. Example:
spanning-tree portfast disable
no spanning-tree portfast
Is there a difference between those 2 commands?

Yes there is a difference, however, it is very slight and subtle - the end result is the same, Portfast no longer runs on that port.
Spanning-tree portfast disable is an EXPLICIT command and will show up in a "show run" or "show start" command.
No spanning-tree portfast is an IMPLICIT command and will therefore NOT show up in the same output.
Hope that helps.
