The SFP is a standard, and if there is any problem with that link, it is
just a reasonable expectation that you won't ask TAC to troubleshoot it
or tell you what is wrong with it, and obviously can't replace it.
There are certainly certified SFPs that work great and others that will
be flaky. If cisco makes a flaky model, it's our responsibility to
support/replace/fix that issue. If you have a problem with a 3rd party
SFP, you would just need to take it up with them.

You will only save money. SFP is a standard media just like USB ports.

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
