MPLS QoS over L2oV

Hello,

I am using the L2oV feature of the iDirect x7 modem to extend MPLS over VSAT.  I am running into issues with the QoS b/c the iDirect system does not recognize the EXP bit.  Has anyone else tried to get iDirect to prioritize packets based on EXP bit and how did you overcome this obstacle?
