Remove interface from running linux server

How to remove network interface without reboot? Don't want to do "/etc/init.d/network restart" just want to completely remove one interface without a reboot. Thanks

thanks, but don't think ifdown will do it. :-) I'm told by the network admins here that "ifdown" only puts the interface in a down state, but the ip address still remains on the interface, where we are looking for a running way to do the equivalent of getting rid of ifcfg-ethX and doing /etc/init.d/network restart". I think the previous post "ifconfig ethX destroy" is a more likely solution, but thank you very much for your response anyway, it is appreciated.

You need to edit the file /etc/sysconfig/network-scripts/ifcfg-ethX. Set ONBOOT=no.
