Description
SE_INPUT_PORT_FAIL
(14:11)
Bit 14 corresponds to port 3, bit 13 corresponds to port 2, bit 12 corresponds to port 1
and bit 11 corresponds to port 0 as follows:
1
Indicates one of the following:
•
•
•
•
No SOC or “10” pattern was present on a switch fabric port input, or
invalid cell code, or
bad idle cell code, or
fabric out of synch.
0
The switch fabric input was normal.
Refer to “SOC Coding” on page 47, “SOC Inversions” on page 47, “Redundant Cell
Present Coding” on page 47, “Idle Cell Pattern Checking” on page 47, Table 3 on page
51, and to Table 5 on page 52 for more information about the SE_INPUT_PORT_FAIL
interrupt.
BP_REMOTE_FAIL
(10:7)
Bit 10 corresponds to port 3, bit 9 corresponds to port 2, bit 8 corresponds to port 1 and
bit 7 corresponds to port 0 as follows:
1
The forward data path from the QRT to the QSE was found to be bad
through signaling on the BP_ACK_IN(3:0) line.
0
The forward data path from the QRT to the QSE was good.
Refer to “Remote Data Path Failure Indication” on page 48, “Liveness of Backpressure
Signal” on page 48, “BP_ACK Remote Failure Detection” on page 50, Table 2 on page
50, and to Table 4 on page 52 for more information about the BP_REMOTE_FAIL
interrupt.
BP_ACK_FAIL
(6:3)
Bit 6 corresponds to port 3, bit 5 corresponds to port 2, bit 4 corresponds to port 1 and
bit 3 corresponds to port 0 as follows:
1
0
BP_ACK_IN(3:0) did not have the special code.
BP_ACK_IN(3:0) had the special code.
Refer to “Liveness of Backpressure Signal” on page 48, “BP_ACK_IN Pattern Check-
ing” on page 49, “BP_ACK Inversion Checking” on page 49, Table 2 on page 50, and to
Table 4 on page 52 for more information about the BP_ACK_FAIL interrupt.
OUT_WD_INT
(2)
1
0
At least one of the UTOPIA output watchdogs is currently expired.
None of the UTOPIA output watchdogs is currently expired.
EQD_INT
(1)
1
0
The device is in the empty congestion state.
The device is not in the empty congestion state.
Reserved
(0)
Initialize to 0 at initial setup. Software modifications to these locations after setup may
cause incorrect operation.
