GBIC errors on Cat 4006

I just installed a new Catalyst 4006 with two 1000BaseX Ethernet WS-X4418 modules. For several GBIC I got a message:

%SYS-3-P2_ERROR: 1/Failed to read gbic serial eeprom on port 3/2, try reinserting %SYS-4-PORT_GBICNOTSUPP:Port 3/2 gbic not supported

The show port command output says: "Unknown GBIC" instead of "1000BaseSX"

but the ports seems to works fine.

I found a Field Notice:

G5484, G5486, G5487 GBICs Generate Bad EPROM Errors

where it is asserted:

"The following available Catalyst software releases have fixed this problem when seeproms are available on the Cisco GBIC:

CatOS 5.5(5) and above

CatOS 6.2(3)and above"

I upgraded to CatOS 6.3(6) but the problem still persist.

Any suggestion ?

Thak You, Alessandro Asson

Re: GBIC errors on Cat 4006

If it is CISCO gbic, then open a TAC case to investigate this issue.

Re: GBIC errors on Cat 4006

I've just cut and paste the error message into Cisco 'Error Message Decoder' and the results were:

1. %SYS-4-PORT_GBICNOTSUPP: Port [dec]/[dec] GBIC is unsupported

This message indicates that an installed GBIC could not be identified because either the GBIC serial EPROM is bad or the GBIC is an unsupported version. [dec]/[dec] is the module number/port number of the faulty GBIC.

Recommended Action: If you are using a Cisco-supported GBIC, contact your technical support representative. Otherwise, either replace the unsupported GBIC with a supported GBIC or disregard the message.

Hope this helps.
