2.7.420 TPTFAIL (G1000)
This TPTFAIL can be raised against Fibre Channel cards if the remote FC card port is down from
SIGLOSS or SYNCLOSS. In that case, the remote FC card port sends a PDI-P error code in the SONET
C2 byte and signals the local FC port transmitter to turn off (thus causing the local FC port to raise the
TPTFAIL alarm). A TPTFAIL can also be raised when a far-end receive fiber is pulled. This alarm can
be demoted when a facility loopback is placed on the FC_MR-4 port.
Clear the TPTFAIL (FCMR) Alarm
Find and clear any path alarms applying to the port. Refer to the correct section of this chapter for trouble
Step 1
clearing instructions. Clearing the path alarm also clears the TPTFAIL.
If the alarm does not clear, log into the Technical Support Website at http://www.cisco.com/techsupport

for more information or call Cisco TAC 1 800 553-2447 in order to report a Service-Affecting (SA)
problem.
2.7.420 TPTFAIL (G1000)
The Transport Layer Failure alarm for the G-Series Ethernet card indicates a break in the end-to-end
Ethernet link integrity feature of the ONS 15454 G1000-4 cards. TPTFAIL indicates a far-end condition
and not a problem with the port reporting TPTFAIL.
The TPTFAIL alarm indicates a problem on either the SONET path or the remote Ethernet port that
prevents the complete end-to-end Ethernet path from working. If any SONET path alarms such as the
"AIS-P" alarm on page
the
causes a TPTFAIL alarm. Also, if the far-end G1000-4 port Ethernet port is administratively disabled or
it is reporting the
indicates the
near-end port.
When a TPTFAIL alarm occurs, the near-end port is automatically disabled (transmit laser turned off).
In turn, the laser shutoff can also cause the external Ethernet device attached at the near end to detect a
link down and turn off its transmitter. This also causes a CARLOSS alarm to occur on the reporting port.
In all cases, the source problem is either in the SONET path being used by the G1000-4 port or the far-
end G1000-4 port to which it is mapped.
An occurrence of TPTFAIL on an ONS 15454 G1000-4 port indicates either a problem with the SONET
path that the port is using or with the far-end G1000-4 port that is mapped to the port.
Note For more information about Ethernet cards, refer to the Cisco ONS 15454 and
Cisco ONS 15454 SDH Ethernet Card Software Feature and Configuration Guide.
Clear the TPTFAIL (G1000) Alarm
Step 1 Clear any alarms being reported by the OC-N card on the G1000-4 circuit.
