Hello Folks, I have a peculiar problem. I have followed postings in the forum and I believe your experience with Cisco networks will help answer my question.
I have a Cisco 2960 with Gigabit SFP module. I connected a third party addon SFP GBIC to 2960 switch and I get the following error that disables the interface. *Mar 16 21:05:15.720: %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi0/2 has bad crc *Mar 16 21:05:15.720: %PM-4-ERR_DISABLE: gbic-invalid error detected on Gi0/2, putting Gi0/2 in err-disable state After checking online I found these two command lines that corrects the error on the Cisco 2960 switch and brings the interface up. 1) no errdisable detect cause gbic-invalid 2) service unsupported-transceiver Cisco 2960 switch however reported a warning on entering the second command: "Warning: When Cisco determines that a fault or defect can be traced to the use of third-party transceivers installed by a customer or reseller, then, at Cisco's discretion, Cisco may withhold support under warranty or a Cisco support program. In the course of providing support for a Cisco networking product Cisco may require that the end user install Cisco transceivers if Cisco determines that removing third-party parts will assist Cisco in diagnosing the cause of a support issue." I understand Cisco's warranty terms mentioned in the above Warning. My worry is, is it safe to do this. Is it likely I will have problems in future with the switch. Am I likely to experience abnormal data transfer on the network in future? Thank You Pamela Pomary ICT Dept.
