Configuring SONET/SDH Alarms

CTC/TL1 has sophisticated SONET/SDH alarm reporting capabilities. As a card in the ONS node, the
ML-Series card reports alarms to CTC/TL-1 like any other ONS card. On the ONS 15454 SONET, the
ML-Series card reports Telcordia GR-253 SONET alarms in the Alarms panel of CTC. For more
All SONET/SDH alarms appear by default But to provision the reporting of SONET/SDH alarms on the
information on alarms and alarm definitions, refer to the "Alarm Troubleshooting" chapter of the
Cisco IOS CLI, perform the following steps beginning in global configuration mode:

Configuring SONET/SDH Delay Triggers

You can set path alarms listed as triggers to bring down the line protocol of the POS interface. When you

Purpose
Enters interface configuration mode and specifies the POS
interface to configure.
Permits console logging of selected SONET/SDH alarms.
Use the no form of the command to disable reporting of a
specific alarm.
The alarms are as follows:
Purpose
• all—All alarms/signals
Enters interface configuration mode and specifies the POS
interface to configure.
encap—Path encapsulation mismatch
•
Permits logging of selected SONET/SDH alarms. Use the no
• pais—Path alarm indication signal
form of the command to disable reporting of a specific alarm.
plop—Path loss of pointer
•
The alarms are as follows:
ppdi—Path payload defect indication
•
all—All alarms/signals
•
pplm—Payload label, C2 mismatch
•
• encap—Path encapsulation mismatch
prdi—Path remote defect indication
•
• pais—Path alarm indication signal
ptim—Path trace identifier mismatch
•
• plop—Path loss of pointer
puneq—Path label equivalent to zero
•
ppdi—Path payload defect indication
•
sd-ber-b3—PBIP BER in excess of SD threshold
•
• pplm—Payload label, C2 mismatch
sf-ber-b3—PBIP BER in excess of SF threshold
•
prdi—Path remote defect indication
•
Returns to the privileged EXEC mode.
ptim—Path trace identifier mismatch
•
(Optional) Saves configuration changes to NVRAM.
puneq—Path label equivalent to zero
•
sd-ber-b3—PBIP BER in excess of SD threshold
•
sf-ber-b3—PBIP BER in excess of SF threshold
•
Returns to the privileged EXEC mode.
