Clear configuration of a removed linecard

Question: I removed a 48 port 10/100/1000BASETX module (WS-X6748-GE-TX ) from my 6509-E switch but the configuration of that module still remains in the running-configuration. How can I clear the configuration of a removed line card?

Answer: Well, this feature has been added to Cisco IOS recently, you need to issue the following global configuration command so when you remove a module, configuration of that module will be cleared,
module clear-config

If you want to negate this feature use:
no module clear-config
