If your only configuring the IP address, subnet mask & default gateway on the switch, there is very little point copying the config from switch to switch, as these are the basic requirements to be able to copy the config.
You can make this setup easy by typing the commands into a text file and simply copying and pasting via hyperterminal.
your text file would read something like:
conf t
int e0
ip address ###.###.###.### ###.###.###.###
no shut
!
ip default-gateway ###.###.###.###
once you have the basic ip setting configured, you can copy a config file via tftp.
To copy a config file from a switch to the tftp server use the command:
switch# copy startup-config tftp
then follow the prompts
to copy from a tftp server back to a switch:
switch# copy tftp startup-config
All the config is saved in the file called 'config' within flash:
