Hi,

Please post both end interface configs (fiber ports). Also, make sure switch recognises the gbic. Do 'Show inter xx' it should tell you the gbic.

Thx

On both switches, can you please post the output to the following commands:

1.  sh version;

2.  sh logs;

3.  sh interface status

Are you sure of that model type? I can't find any switch with the model 3960G - are you sure they're not 2960G?

Anyway, have you tried the command "media-type sfp" on the ports you're using for the fibre link?

Cheers
