it is a data link issue...forget about the masking. without ip or with ip configed ..if you have the correct cable for bach to back connection. i would only check the clock rate statement on the DCE side and make sure that the cable is good. do s sho contr serial X and check if in fact you have DCE on one side and DTE on the other Tariq wrote: Hello Everybody. I am getting very strange problem in my home network. I am getting Status is up and line protocol is down message. Please check the attached diagram. I am unable to coonect Serial 1 of Router 2 with Serial 1 of router 3 I applied clock rate 64000 command on serial 1 interface of Router 2. Encapsulation on both ends is HDLC. I changed keepalive but was no success. Default keepalive is 10. Cable and interface is is 100% ok thats why status is up. Line Protocol is down means that there is some problems on datalink layer. I think that it could be some masking problem. Please see it and let me know.
