Recently purchased some 1000Base-T Mini-GBIC SFPs (MGBT1) under the impression that they were full-fledged Cisco devices with intent to use them in our 3560G-48TS. As I hotplug them in, I receive the following:
%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi0/48 has bad crc
%PM-4-ERR_DISABLE: gbic-invalid error detected on Gi0/48, putting Gi0/48 in err-disable state
The interfaces do not come online at this point, nor does it seem I can force them to. My research has found mixed feelings on whether this error is show-stopping or not.
I am running the following on my 3560G
Cisco IOS Software, C2960 Software (C2960-LANBASEK9-M), Version 12.2(44)SE6
Does anyone have any input as to whether the MGBT1 can actually (reliably) work with the 3560G and if so, how?
Please let me know if I have forgotten any critical information.
