There are eight transmit queues in each transmit FIFO. Software has some flexibility in determining how packets are loaded into the queues and on how packet priorities are selected for transmission (how packets are removed and transmitted from queues). All ports on the switch have identical FIFO's. For the purposes of the below the transmit FIFO is switch egress even though the port 0 transmit FIFO is connected to the CPPI receive (also switch egress). The CPPI nomenclature is reversed from the Ethernet port nomenclature due to legacy reasons.
