RX_CH_ALTERNATE_ENCODE
(16)
1
Enable RX_CH alternate congestion encoding. This set of values of the
RX_CH_EXP_MAX_QD and RX_CH_EXP_CONG_QD defines many
of the codepoints with higher values. This increases the resolution of the
congestion limits where they are used most of the time. The table is
shown in the text for RX_ALTERNATE_ENCODE.
Disable RX_CH alternate encoding. This setting uses the original set of
values which are approximately 2**N. The table is shown in the text for
RX_ALTERNATE_ENCODE.

DISABLE_P4
(15)
1
Disable the 4th instance of the P process. The P process updates the data
structures with the results of crossing the switch fabric. P4 works as a
pair with S4.
Enable this process.
0
DISABLE_P3
(14)
1
0
Disable the 3rd instance of the P process. P3 works as a pair with S3.
Enable this process.
DISABLE_P2
(13)
1
0
Disable the 2nd instance of the P process. P2 works as a pair with S2.
Enable this process.
DISABLE_P1
(12)
1
0
Disable the 1st instance of the P process. P1 works as a pair with S1.
Enable this process.
DISABLE_S4
(11)
1
Disable the 4th instance of the S process. The S process selects the cells
to be sent to the switch fabric. When
DISABLE_RANDOMIZATION=1, S4 is associated with switch fabric
port 3.
Enable this process.
0
DISABLE_S3
(10)
1
Disable the 3rd instance of the S process.When
DISABLE_RANDOMIZATION=1, S3 is associated with switch fabric
port 2.
0
Enable this process.
DISABLE_S2
(9)
1
Disable the 2nd instance of the S process. When
DISABLE_RANDOMIZATION=1, S2 is associated with switch fabric
port 1.
Enable this process.
0
DISABLE_S1
(8)
1
Disable the 1st instance of the S process. When
DISABLE_RANDOMIZATION=1, S1 is associated with switch fabric
port 0.
Enable this process.
0
DROP_ALL_RX_CELLS
(7)
1
0
Drop all cells received in the RX direction.
Normal operation.
DISABLE_U3
(6)
1
Disable the 3rd instance of the U process. The U process enqueues the
cells onto the data structures.
Enable this process.
0
DISABLE_U2
(5)
1
0
Disable the 2nd instance of the U process.
Enable this process.
