Bit [3:0]:
Per source buffer reservation. Define the space in the FDB reserved for each port.
Expressed in multiples of 16 packets. For each packet 1536 bytes are reserved in the
memory.
Default
: 4'hA for 4MB memory
4'h6 for 2MB memory
4'h3 for 1MB memory
Bits [7:4]:
Expressed in multiples of 16 packets. Threshold for dropping all best effort frames when
destination port best effort queues reach UCC threshold and shared pool is all used and
source port reservation is at or below the PRG[7:4] level. Also the threshold for initiating UC
flow control.
Default
: 4'h6 for 4MB memory
4'h2 for 2MB memory
4'h1 for 1MB memory

Shared buffer size
Bits [7:0]:
Expressed in multiples of 8. Buffer reservation for shared pool.
- (Default 4G & 4M = 8'd62)
- (Default 4G & 2M = 8'd20)
- (Default 4G & 1M = 8'd08)
- (Default 8G & 4M = 8'd150)
- (Default 8G & 2M = 8'd55)
- (Default 8G & 1M = 8'd25)

Class 2 FCB Reservation
Bits [7:0]:
Buffer reservation for class 2 (third lowest priority). Granularity 2.
(Default 8'h00)
