type in int ? and it will show you what you can enter. chances are you need to enter int f0 or int f0/0

that did it. thanks!

one more question:

when I try backing up the conifg off of the router via tftp I keep getting an error opening the backup file (timed out).

on the system I am transferring the file to i see a file with the correct name, but it is '0' bytes in size.

is there something I am supposed to do before I start the transfer to allow it to copy?
