Register Descriptions
Note: ABR Congestion Indication is done in RM cells of the backward ABR connection.
In Bi-directional Mode, these cells are handled by the opposite core (therefore
ABRdir must be 1 for each ABR QID). In Mini-switch Mode, these cells can be
handled from the same or opposite core depending on configuration. (If only one
core will be used ,ABRdir must be 0 for each ABR QID.)
flag 2
CI-Flag:
Whenever a cell is accepted the respective queue threshold values
are checked. In case a CI condition is detected, this condition is
stored in flag2 for further recognition by resource monitoring
operation (ABR).
It is recommended to set this bit to 0 during queue setup.
Do not Write during normal operation.
flag 1
NI-Flag:
Whenever a cell is accepted the respective queue threshold values
are checked. In case a NI condition is detected, this condition is
stored in flag1 for further recognition by resource monitoring
operation (ABR).
It is recommended to set this bit to 0 during queue setup.
Do not Write during normal operation.
flag 0
•
EFCI-Flag:
Whenever a cell is accepted the respective queue threshold values
are checked. In case a EFCI condition is detected, this condition is
stored in flag0 for further recognition by resource monitoring
operation (ABR).
It is recommended to set this bit to 0 during queue setup.
Do not Write during normal operation.
