ADIN2111 evaluation board frame generator demo

Hello

I have the evaluation board of ADIN2111 and ADIN1100.

I tried to do the frame generator /checker demo using Fixed IP  referring to URL "wiki.analog.com/.../eval-adin2111ebz-user-guide "

I could show below on terminal

Could you tell me know what RX, Diff and Err means ?

(If possible, could you tell me how I can change the status of RX,Diff , Err =0 )

start
OK
CH1 -37.2 dB,CH2 MSE n/a , Rx 0, Diff 0, Err 0
CH1 -37.2 dB,CH2 MSE n/a , Rx 0, Diff 0, Err 0
CH1 -37.2 dB,CH2 MSE n/a , Rx 0, Diff 0, Err 0
CH1 -37.2 dB,CH2 MSE n/a , Rx 0, Diff 0, Err 0
CH1 -37.2 dB,CH2 MSE n/a , Rx 0, Diff 0, Err 0
stop
OK
