SecureStack B2
Firmware 4.00.26 


Express Forwarded traffic is not transmitted from high priority hardware queue 

If DiffServ is used to mark the DSCP value of a frame based on a keyword of "ef" or a value of 46 (with either of these yielding L3 Express Forwarding), as a side-function the outgoing L2 frame should be placed into the highest priority hardware queue (Queue 5) for transmission (5848). 

This side-functionality is broken, with the above-stated product and firmware. 

Upgrade to firmware 4.00.60 or higher.
