1549.0. "MAC CRC Error ???" by ZPOVC::CHINHENG () Mon Jan 09 1995 06:28

Hi,

   I have a customer system, SABLE running OSF/1 V3.0, with a DEFEA
   Fddi controller. This system keeps getting "fta0: MAC CRC Error",
   about 4-5 messages over a week.
 
   Can somebody help to explain what's "MAC CRC Error" and if there is
   any cause of alarm.

   Thanks for any comment/advise.

	This means the device/driver received a packet with bad CRC. This
	is a non-fatal error: packet is discarded (sender will transmit
	again in most cases).

	This might be due to bad hardware: module or cable. Perhaps 
	re-seeding or using another slot might help.
