No, Dual FIFO does not mean "a pair of poodles." That would be Dual FOOFOO. Then again, it may be Dual FIDO. Anyway.... While browsing on CCO I found a better explanation of the Dual FIFO queue. This excerpt is taken from: http://www.cisco.com/univercd/cc/td/doc/cisintwk/intsolns/qossol/qosvoip.htm#xtocid635517 At the interface level, a FIFO queue is set up unless you have enabled FRF.12 fragmentation. In that case, a dual FIFO system is set up with a high priority queue and a low priority queue. The high priority queue receives the PQ traffic from all PVCs plus Layer 2 control traffic. The low priority queue receives all other traffic from all PVCs. Remember that Frame Relay traffic shaping (FRTS) is required for Frame Relay circuits whether FRF.12 fragmentation is enabled or not. FRTS provides the back-pressure mechanism to detect congestion per PVC. Support for ATM PVCs is available in Cisco IOS Release 12.2(1)T.
