I have NNI and subinterface cisco ASR9K

[ahmed.benabdalla9]

I have NNI on hu0/0/0/38 port and when I show int : 38980870 input errors, 38980846 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort 

I tried to trun this circut to the carrier they say they cant tested unless actual circute and this NNI has at least 25 subinterface to different sites , 

when I check each of the subinterface I cant see alot of input error or high CRC 

can you please advise ?

Check and make sure there is no duplex mismatch on the physical interface.

Hello @ahmed.benabdalla9 ,

you need to compare the input errors and the total input packets  the error ratio is :

( input errors ) / (inputerrors + inputPackets)

if this is less then 1% you are fine

Hope to help
