Hello Niranjan
I do not see an option just for pause-rate-limit. Can you try disabling it for all and see it disables it for pause-rate-limit as well?
20-08-5020-A(config)# no errdisable detect cause ?
all Enable error detection on all cases
link-flap Enable error disable detection on linkstate-flapping
loopback Enable error disable detection on loopback
20-08-5020-A(config)# no errdisable detect cause
Since you know a server is doing it, I would investigate why its sending so much pause.
Thanks
