In addition, there is a shared pool, which can store any type of frame. The registers related to the Buffer
Management logic are:
PRG- Port Reservation for Gigabit Ports and CPU port
SFCB- Share FCB Size
C2RS- Class 2 Reserved Size
C3RS- Class 3 Reserved Size
C4RS- Class 4 Reserved Size
C5RS- Class 5 Reserved Size
C6RS- Class 6 Reserved Size
C7RS- Class 7 Reserved Size
Figure 5 - Buffer Partition Scheme Used in the MVTX2802AG
7.8.1 Dropping When Buffers Are Scarce
Summarizing the two examples of local dropping discussed earlier in this chapter:
If a queue is a delay-bounded queue, we have a multilevel WRED drop scheme, designed to control delay
and partition bandwidth in case of congestion.
If a queue is a WFQ-scheduled queue, we have a multilevel WRED drop scheme, designed to prevent
congestion.
In addition to these reasons for dropping, the MVTX2802AG also drops frames when global buffer space becomes
scarce. The function of buffer management is to ensure that such droppings cause as little blocking as possible.
