I am trying to connect "sfp-1ge-fe-e-t" sfp module to CISCO Catalyst C3560G-48TS switch.
When i pluged module to the port and following error was shown:
%GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port Gi0/49 has bad crc
Then I searched solution for the problem, so I found several solution that describes same steps.
I tried following commands:
# service unsupported-transceiver # no errdisable detect cause sfp-config-mismatch # no errdisable detect cause gbic-invalid
But it didn't help actually. I couldn't turn on GBIC ports. It always shows "status down, protocol down".
show idprom interface gigabitEthernet 0/49 command doesn't show anything.
I have been experiencing with the proplem for two days.
Which steps should i follow? what is the real solution? Thanks in advance
