Cisco ONS 15310-CL and Cisco ONS 15310-MA Troubleshooting Guide, R7.0
Chapter 2 Alarm Troubleshooting
2.7.192 RFI-P
A Remote Fault Indication (RFI) Line condition occurs when the ONS 15310-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
Step 1 Log into the node at the far-end of the reporting ONS 15310-CL or ONS 15310-MA.
Step 2 Identify and clear any alarms, particularly the “LOS (OCN)” alarm on page 2-98.
Step 3 If the condition 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).
2.7.192 RFI-P
Default Severity: Not Reported (NR), Non-Service-Affecting (NSA)
SONET Logical Objects: STSMON, STSTRM
An RFI Path condition occurs when the ONS 15310-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
Step 1 Verify that the ports are enabled and in service (IS) on the reporting ONS 15310-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.
Step 2 To find the path and node failure, verify the integrity of the SONET STS circuit path at each of the
intermediate SONET nodes.
Step 3 Clear alarms in the node with the failure, especially the “UNEQ-P” alarm on page 2-142.
Step 4 If the condition 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).
