Serial and ethernet ports

Lets say a router has one serial and one ethernet connection. Is there any way to tie the health of the serial link to the health of the ethernet port? What I want to happen is if the serial link goes down, the ethernet port also has to go down (stop responding to arps and any traffic directed to it).

Re: Serial and ethernet ports

I don't think there is such a feature but depending upon why you need to tie the health of the two, there might be other options like HSRP tracking:
