I have just plugged some non Cisco Copper SFP's into 3560's I am getting *Mar 1 00:00:31.826: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi0/1 has bad crc I have tried the usual "service unsupported-transceiver" and no "errdisable detect cause gbic-invalid" But am still not getting the SFP to come up. Any other suggestions? Ta
