Srivathsan, I think you're right. Is also suggested by this note in http://www.cisco.com/warp/public/125/12.html#topic8. "Note: Make sure you configure the DLCIs to correspond with the priority list, or the system will not use the correct queue."
The primary DLCI is linked to the subinterface. The secondary DLCIs are also implicit linked to this subinterface in the example below. interface Serial0.1 point-to-point ip address 4.0.1.1 255.255.255.0 frame-relay priority-dlci-group 1 140 180 190 200 frame-relay interface-dlci 140 So if you lose your primary DLCI (your subinterface), you also lose all other traffic on the secondary DLCIs.

This is coz it's the first dlci mentioned in the frame-relay priority-dlci-group command ( in the interface / subinterface configuration mode )that's always the primary . I quote the following from the cisco site.. " Implementation Considerations When implementing DLCI prioritization, please note the following points: If a secondary DLCI goes down, you lose traffic destined for that queue only. If you lose the primary DLCI, the subinterface goes down and you lose all traffic. " What does the second point mean...??
