While testing some new hardware I stumbled across a new command I
think can be quite useful. It is "config replace". What it does is
aloows you to load another config onto flash and "replace" the existing
config with a new config in a nice quick clean fashion. With the
optional "list" command the IOS will list all of the changes.
USBtest#conf replace usbflash0:running-config list
This will apply all necessary additions and deletions
to replace the current running configuration with the
contents of the specified configuration file, which is
assumed to be a complete configuration, not a partial
configuration. Enter Y if you are sure you want to proceed. ? [no]: y
!Pass 1
!List of Commands:
no hostname Replacetest
no interface Loopback0
interface FastEthernet0/0
no ip address 172.28.64.229 255.255.255.0
no router rip
hostname MAYDAY
interface FastEthernet0/0
ip address 172.28.64.222 255.255.255.0
end
My new config I replaced the old one with had no loopback interface
or router rip and had a new hostname. With replace the extraneous
commands are deleted automatically, no need to "no" them out in a
config file and no reloads!
Looks like it is available in 12.3, not sure exactly when it first
came out.
