We just bought some used 2501 routers for educational purposes. Along with the routers came serial cables (DB-60 to V.35) so we could connect the routers back to back. After hours of troubleshooting we measured the cables and found out that the cables (DCE) had no shortening between the pins that are used by the router to detect the cable type.
My questions is:
Is there any chance we could override the cable detection in IOS so that the router brings the interface to state up without checking the cable? (The cable passed our measure test in all other aspects, i.e. the cable is functional, the only thing that is wrong is that the shoring pins is not shorted.)
If not, I believe we have to crack the cable open and short the pins manually?
(Do I need to point out that the cables obviously not are Cisco original?)
