Chapter2 Alarm Troubleshooting
2.7.192 RFI-P
A Remote Fault Indication (RFI) Line condition occurs when the ONS15310-CL or ONS 15310-MA
detects an RFI in OC-3 or OC-12 port SONET overhead because of a fault in another node. Resolving
the fault in the adjoining node clears the RFI-L condition in the reporting node. RFI-L indicates that the
condition is occurring at the line level.

Clear the RFI-L Condition

Step1 Log into the node at the far-end of the reporting ONS15310-CL or ONS 15310-MA.
Step2 Identify and clear any alarms, particularly the “LOS (OCN)” alarm on page 2-98.
Step3 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call CiscoTAC (1-800-553-2447).
2.7.192 RFI-P
Default Severity: NotReported (NR), Non-Service-Affecting (NSA)
SONET Logical Objects: STSMON, STSTRM
An RFI Path condition occurs when the ONS15310-CL or ONS 15310-MA detects an RFI in the an
STS-1 signal SONET overhead because of a fault in another node. Resolving the fault in the adjoining
node clears the RFI-P condition in the reporting node. RFI-P occurs in the terminating node in that path
segment.

Clear the RFI-P Condition

Step1 Verify that the ports are enabled and in service (IS) on the reporting ONS15310-CL or ONS 15310-MA
by completing the following steps:
a. Confirm that the green ACT LED is on.
b. To determine whether the OC-3 or OC-12 port is in service, double-click the 15310-CL-CTX or
CTX2500 card in CTC to display the card view.
c. Click the Provisioning > Optical > Line tabs.
d. Verify that the Admin State column lists the port as IS.
e. If the Admin State column lists the port as OOS, click the column and choose IS. Click Apply.
Note If ports managed into IS administrative state are not receiving signals, the LOS alarm is
either raised or remains, and the port service state transitions to OOS-AU,FLT.
Step2 To find the path and node failure, verify the integrity of the SONET STS circuit path at each of the
intermediate SONET nodes.
Step3 Clear alarms in the node with the failure, especially the “UNEQ-P” alarm on page2-142.
Step4 If the condition does not clear, log into the Technical Support Website at
http://www.cisco.com/techsupport for more information or call CiscoTAC (1-800-553-2447).
