On my 3750 switch on my 10Gig interface I am seeing "Transmit Discards". Can someone please direct me as to what could be causing this and how I check for it?

Hello Dan,

this may not mean that there is a real issue.

a L2 switch does not forward frames if it thinks the destination MAC address is out the same port on which the frame is received.

this is the MAC address filtering action.

please post the sh int ten x/y

Hope to help
