GBIC_SECURITY_CRYPT-4-ID_MISMATCH: Identification check failed for GBIC in port X

There could be a situations that you insert optic’s in Cisco ASR 900 series and get such alarm:

 

GBIC_SECURITY_CRYPT-4-ID_MISMATCH: Identification check failed for GBIC in port

 

This alarm means that equipment recognize module as Cisco SFP, but existing SFP type is not supported in Cisco ASR series. This could be the case with BX-U/D models or other models which sometimes are not supported in all platforms.

To have a check if current SFP is supported under Cisco platform can use the Cisco transceiver compatibility matrix.

You can use following commands, so that these modules are not turned off by Cisco device:

service-unsupported transceiver

Or:

service-unsupported transceiver
errdisable recovery cause all
errdisable recovery interval 30
