Interface tracking on Cisco routers

Hi Guys

I am new to the forums but i have read a lot of topics in these forums and have seen you guys are very helpful. I also hope i am putting this in the correct section.

I need help with interface tracking on Cisco routers. I need a serial interface to track a fast ethernet interface.

My problem is my fast ethernet port went down due to a power issue but traffic was still coming through the serial interace targeted for the fastethernet interface. I need to track this interface so when it goes down it will shut down the serial interface so my other devices will know to route through the backup route.

I know this is not much information but im not sure what else to tell you. I don't have to much experience with cisco i only have 10 months experience and i don't know much about tracking interfaces. I would like to know is it possible to do this and if so could you please help me even if someone has any links to a web site that has the information. I have looked on google but im not sure if what i found is correct here is the link for the site i found http://www.cisco.com/en/US/docs/io [...] iptrk.html

Thanks.

Hi

I also forgot to mention i want to do this without using HSRP. I have another proprietary device that well divert traffic once it knows the serial link is down.

Thanks.

Hey

Thanks for the reply

I figured out eventually i couldn't do it that way but i think i might be able to make a script using tcl to get it to work. You wouldn't happen to no how to do that? Or even know any good links that could help me learn it?

Hi

I dont have another connection on the router to the same destination. I just need to shutdown the serial interface when the other interface goes down without using HSRP. The other interface is using x25 not IP. I no it's not possible to do what i need without making a tcl script so im learning it now and hopefully ill be able to figure out how to create a script for wat i need.
