How can I Remove an ip helper router wide??

[mctiesman]

I have an old legacy ip helper address I need to clean on various pieces of network gear. Does anyone know some kind of black magic command that would allow me to remove the ip helper from numerous interfaces without having to touch each interface? Would using the range command still work even if some of the interfaces do not have the ip helper I am trying to remove? Thanks.

I believe the range command would work. Since you're removing a command that may, or may not, be defined, it shouldn't raise an issue on the interfaces where it's not defined.

Only issue that comes to mind, if you try a range command for interfaces that don't exist, then I believe the command will fail.
