CRC error checking on interface

Unanswered Question
Mar 6th, 2008

Hi,

Is is possible to disable CRC error checking on any type of interface ? If possible what is the command for it. I know that I can configure crc 32 and crc 16 on interface. But can I stop crc error checking on an interface ?

Thanks

I have this problem too.

To disable the 32-bit CRC and return the interface to the default 16-bit CRC, enter the no crc 32 command.

Ex,

Router(config)# interface pos 7/1

Router(config-if)#no crc 32

No you can't, because crc is part of the transmission standards, and if you was to ignore crc, you would accept potentially corrupted data, with unpredictable consequences.

Hi,

crc 32 or crc 16 which will detect more transmission errors ?

Thanks

crc 32 is a more robust and better error detection code.

hope this helps, please rate post if it does!
