Installing SFP Módules.

Hi I´am installing SFP Módules in Catalyst 2970 switch but are not Cisco SFP módules.

When I put SFP into SFP module Slots:

Gbic_security_Crypt_4_VN_Data_CRC_error.

2970 switch supports only Cisco SFP Modules??????

any idea.....troubleshooting.

Thank´s you.

Re: Installing SFP Módules.

1. %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port [dec] has bad crc.

This message means that the GBIC module was identified as a Cisco GBIC module, but it does not have a valid CRC in the EEPROM data. [dec] is the interface in which the module is installed.

Recommended Action: Verify that the software release that is running on the system supports the GBIC module. If the GBIC module is newer, a system software upgrade might be required. Even if the GBIC module is unrecognized by the system, the GBIC module might still operate properly, but it will have limited functionality.

2. %GBIC_SECURITY_CRYPT-4-VN_DATA_CRC_ERROR: GBIC in port [dec] has bad crc

The GBIC was identified as a Cisco GBIC, but it does not have a valid CRC in the EEPROM data.

Recommended Action: Verify that the Cisco IOS software running on the system supports the GBIC. If the GBIC is newer, a system software upgrade might be required. Even if the GBIC is unrecognized by the system, the GBIC may still operate properly but might have limited functionality.
