c2960 duplex mismatch errors

I have a ws-c2960g-48 tc-l software ver 12.2.25 SEE3 that when I use SFP GLC-GE-100FX I get duplex errors ports 45-48 do not have the option to set duplex full on them. How do you change duplex from auto to duplex full on them?

Jim,

Under the interface specify the media type ( media-type sfp ) then try changing settings see if that works.

go through this document for reference
