Hello folks -
I have a stack of 3750 switches that are trunked to several 2960 switches using MMF (LT/SC connector). The SFP that is in use is GLC-GE-100FX.
However, all the trunk ports between the 3750 and the 2960's are running on half duplex. There is no manual setting on either the 3750 or the 2960 configured for half duplex.
So I am not sure why these trunks are running at half duplex. On the 2960's, under the trunk interface, I don't even have an option to set the duplex manually.
Any thoughts would be appreciated.
