Re: DATA _CRC_ERROR on GBIC

Hi.

Are you using Cisco-supplied SFP or is it third-party SFP? If it is the latter, that's most probably the cause.

There is a command (a hidden one) which enables the switch to accept third-party SFP. It is "service unsupported-transceiver". Be aware, though, that if you use that command, Cisco reserves the right to not provide you service in case of problems if they deem the third-party SFP to be the cause of problem.

You might have to upgrade to newer versions than the ones you have (especially on the 3560) to have the support for the command.
