Pdi-P - Cisco NCS 2000 series Troubleshooting Manual

PDI-P

If the condition does not clear, log into the Technical Support Website at
for more information or call Cisco TAC (1 800 553-2447).
PDI-P
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical Object: STSMON, STSTRM
PDI-P is a set of application-specific codes indicating a signal label mismatch failure (SLMF) in the NCS
STS path overhead. The condition indicates to downstream equipment that there is a defect in one or more of
the directly mapped payloads contained in that STS synchronous payload envelope (SPE). For example, the
mismatch could occur in the overhead to the path selector in a downstream node configured as part of a path
protection. The PDI-P codes appear in the STS Signal Label (C2 byte).
An SLMF often occurs when the payload (for example, ATM) does not match what the signal label is reporting.
The
reported with the AIS, clearing PDI-P clears the AIS. PDI-P can also occur during an upgrade, but usually
clears itself and is not a valid condition.
A PDI-P condition reported on an OC-N port supporting a G1000-4 card circuit could result from the end-to-end
Ethernet link integrity feature of the G1000-4 card. If the link integrity is the cause of the path defect, it is
typically accompanied by the TPTFAIL (G1000) or the CARLOSS (G1000) reported against one or both
Ethernet ports terminating the circuit. If this is the case, clear the TPTFAIL and CARLOSS alarms to resolve
the PDI-P condition.
A PDI-P condition reported on an OC-N port supporting an ML-Series card circuit could result from the
end-to-end Ethernet link integrity feature of the ML-Series card. If the link integrity is the cause, it is typically
accompanied by the TPTFAIL (ML100T, ML1000, MLFX) reported against one or both POS ports terminating
the circuit. If TPTFAIL is reported against one or both of the POS ports, troubleshooting the accompanying
alarm clears the PDI-P condition. Refer to the SDH Ethernet Card Software Feature and Configuration Guide
for more information about ML-Series cards.
Warning The laser is on when the card is booted and the safety key is in the on position (labeled 1). The port does
not have to be in service for the laser to be on. The laser is off when the safety key is off (labeled 0).
Statement 293
Warning Invisible laser radiation could be emitted from the end of the unterminated fiber cable or connector.
Do not stare into the beam directly with optical instruments. Viewing the laser output with certain
optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm
could pose an eye hazard. Statement 1056
Warning
Use of controls, adjustments, or performing procedures other than those specified could result in
hazardous radiation exposure. Statement 1057
