reliability 128/255, txload 1/255, rxload 1/255

Hi all,

Has anyone perhaps dealt with this issue before. I have some incidents where my clients reports links either (MW or FIBRE) saying the link is up but the "reliability" is LOW..

Se7/2/1:0 up up SDHACSI1 <DHA> 53/13837/00 | N4988 U3 IF2
CPEGNUMS01#sh int Se7/2/1:0
Serial7/2/1:0 is up, line protocol is up
Hardware is SPA-8XCHT1/E1
Description: SDHACSI1 <DHA> 53/13837/00 | N4988 U3 IF2
Internet address is 10.x.x.x/30
MTU 1500 bytes, BW 1984 Kbit/sec, DLY 20000 usec,
reliability 128/255, txload 1/255, rxload 1/255

If someone can please share some light on this as I have not dealt with this issue before and it occurs on different mediums.

I found this on Cisco Forum https://community.cisco.com/t5/swit...onship-to-input-rate-output-rate/td-p/2004028 and I think I've answered the question..

The reliability of an interface is always reported as a fraction of 255 (255/255 is 100% reliability), calculated as an exponential average over 5 minutes. So you want to see the reliability at 255/255. If this drops below this value, then you have problems on the link. Typically, any layer 1 or layer 2 issues will bring this number down say 228/255
