L2ProtocolTunnel Traffic P-Bit value of 5

Hello,

I have a Customer where his Layer 2 encapsulated traffic is remark with a priority bit 5 even is send with mark of 0.

He is using Me3400s and is using L2 protocol tunneling

Test equip Sender   ----gi0/1  Me3400  gi 0/13 -----Me6500 --------(Tunnel)------Juniper Switch----( Recever equipment )


Im assuming this is how it should work, Cos for the encapsulated traffic such as CDP,STP,LLDP is always 5 right ?
