We are having CA unicenter spectrum NMS used for wan links monitering. We found that some links were flapping quite frequently over a perion of time. So we monitered the link for 12 hours but we did not see any interface resets in 12 hours. There were CRCs & input error's. So is it so that the link is down and up interface reset count remains the same. How to identify the exact problem. One soluation was to keep the continuous ping on the other end ip address of wan link. This is ok for 10/15 wan links but as we are monitering more that 650 links keeping continuous ping is not practical solution.
Thanks in advance
