Cisco mds MAC_RX_BAD_WORDS_FROM

Hello, 

I can not find a description in the documentation "error stat name".
I'm interested in what it means
"FCP_CNTR_MAC_RX_BAD_WORDS_FROM_D"

Is this a problem in SFP module ?

Re: Cisco mds MAC_RX_BAD_WORDS_FROM

Greetings.

You may want to check #sh module internal exceptionlog module 1

Are your transceiver power levels ok? #show int fc1/26 transceiver details

Could be issue with transceiver, cable, or device on other end of this link.

 

Also, are these numbers continuing to increment?

 

Thanks,

Kirk...

No, this happens when the link down/up between the switch and storage system.
