Chapter 2 Alarm Troubleshooting

Alarm Procedures

Clear the RPRW Condition

Step 1 Look for and clear any service-affecting SONET path-level alarms on the affected circuit, such as the

“LOP-P” alarm on page 2-98, “PLM-P” alarm on page 2-122, or the “TIM-P” alarm on page 2-148.

Clearing this alarm can also clear RPRW.

Step 2 If the condition does not clear, look for and clear any service alarms for the Ethernet card itself, such as

the “CARLOSS (CE100T, CEMR)” alarm on page 2-37 or the “TPTFAIL” alarm on page 2-149.

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).

2.7.206 RUNCFG-SAVENEED

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Object: EQPT

The Run Configuration Save Needed condition occurs when you change the running configuration file

for ML-100T-8 card. It is a reminder that you must save the change to the startup configuration file for

it to be permanent.

The condition clears after you save the running configuration to the startup configuration, such as by

entering the following command at the CLI:

copy run start

at the privileged EXEC mode of the Cisco IOS CLI. If you do not save the change, the change is lost

after the card reboots. If the command “copy run start” is executed in configuration mode and not

privileged EXEC mode, the running configuration will be saved, but the alarm will not clear.

2.7.207 SD

Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)

SONET Logical Objects: DS1, DS3

A Signal Degrade condition for a DS-1 or DS-3 signal on a 15310-CL-CTX, DS1-28/DS3-EC1-3, or

DS1-84/DS3-EC1-3 card occurs when the quality of an electrical signal has exceeded the BER signal

degrade threshold. Signal degrade is defined by Telcordia as a soft failure condition. SD and signal fail

(SF) both monitor the incoming BER and are similar conditions, but SD is triggered at a lower bit error

rate than SF.

The BER threshold is user-provisionable and has a range for SD from 1E–9 dBm to 1E–5 dBm.

SD can be reported on electrical ports that are In-Service and Normal (IS-NR); Out-of-Service and

Autonomous, Automatic In-Service (OOS-AU,AIS); or OOS-MA,MT, but not in the Out-of-Service and

Management, Disabled (OOS-MA,DSBLD) service state. The BER count increase associated with this

alarm does not take an IS-NR port out of service, but if it occurs on an AINS port, the alarm prevents

the port from going into service.

The SD condition clears when the BER level falls to one-tenth of the threshold level that triggered the

condition. A BER increase is sometimes caused by a physical fiber problem (including a faulty fiber

connection), a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice. SD can also

be caused by repeated 15310-CL-CTX card resets that in turn can cause switching on the lines or paths.
