Can anyone tell me what exactly the noise stats relate to when i run show line on a 2511 as on some ports the value is increasing all the time - is this due to attenuation on the cabling? Any ideas would be appreciated. Thanks
I believe that when the 2511 gets any electrical signal on those async lines which it can not process as valid communications signal it counts as noise. If something is connected and passes along any static or has a faulty connector, or anything like that it can cause increasing counters for noise.
Thanks for the info - I thought that this would be the case - do you think installing STP cabling or something like that would help? As i suspect that if the noise gets to high then it would start to clog the buffer and cause the router to crash. Cheers.
Hi Rick - yes we have the exact config you refer to - I think I will change the cable type to STP/FTP to see if that helps. I will post the results on here when I have them if you are still interested. Thanks mate.
