Symbol: EMPD
Address Offset: 000B4h
Default Value: 00000000h
Access:
Read/Write
This specifies if a given priority should allow multicast cells to be dropped.
Bits
Description
31:4
Reserved
This specifies if a given priority should allow multicast cells to be dropped. If a bit is
1, then the output port processor does not assert backpressure for the corresponding multicast
queue. If a bit is 0, then the output port processor prevents dropping of multicast cells by
asserting backpressure to the central scheduler. Bit 3 is for priority 3, bit 2 is for priority 2, bit 1
is for priority 1, and bit 0 is for priority 0.
