Toggling Serial Interface

Hi,

I have configured 2600 series router for internet connection, but the problem is that my router's serial interface is not stable >the message am getting is "%LINE PROTO-5-UPDOWN : Line protocol on Interface serial 0/0 , changed state to down"....again after 10 to 15 seconds i am getting ""%LINE PROTO-5-UPDOWN : Line protocol on Interface serial 0/0 , changed state to up"

Means the status of serial interface is toggling.I have checked Keepalive, encapsulation on both sides.

I am looking for immediate response from you guys..

thanks

rijo

Re: Toggling Serial Interface

this is because your Data circuit is not working properly. troubleshoot the data circuit. Its purely data circuit problem.not anything related to configs.
