Lỗi không nhận thẻ SFP Cisco-SFP GBIC-SECURITY CHECK FAIL AND GBIC-INVALID

 

PROBLEM:

I recently had to use some none Cisco 10Gbs copper SFP’s in a 3850 stack. On inserting the SFP’s the interfaces went into err-disabled status and looking in the log I was getting the message “Warning: SFP gbic-security check fail” and “gbic-invalid”.



SOLUTION:

Using the below commands I was able to get the device to not put the the interface into err-disabled when a non Cisco SFP was used.

service unsupported-transceiver
no errdisable detect cause gbic-invalid

 

I then had run a shut and a no shut on the interface, after that everything came up fine and everything looked good when looking at the capabilities of the interface.
