SONET/SDH Alarms

Configuring SONET/SDH Alarms

All SONET/SDH alarms appear by default But to provision the reporting of SONET/SDH alarms on the

Cisco IOS CLI, perform the following steps beginning in global configuration mode:

To determine which alarms are reported on the POS interface and to display the bit error rate (BER)

thresholds, use the show controllers pos command, as described in the “Monitoring and Verifying POS”

section on page 5-9.

Note

Cisco IOS alarm reporting commands apply only to the Cisco IOS CLI. SONET/SDH alarms reported

to the TCC2/TCC2P are not affected.

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

configure the path alarms as triggers, you can also specify a delay for the triggers using the pos trigger

delay command. You can set the delay from 200 to 2000 ms. If you do not specify a time interval, the

default delay is set to 200 ms.

Command Purpose

Step 1

Router(config)# interface pos

number

Enters interface configuration mode and specifies the POS

interface to configure.

Step 2

Router(config-if)# pos report

{all | encap | pais | plop | ppdi

sd-ber-b3 | sf-ber-b3}

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:

•

all—All alarms/signals

•

encap—Path encapsulation mismatch

•

pais—Path alarm indication signal

•

plop—Path loss of pointer

•

ppdi—Path payload defect indication

•

pplm—Payload label, C2 mismatch

•

prdi—Path remote defect indication

•

ptim—Path trace identifier mismatch

•

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

Step 3

Router(config-if)# end

Returns to the privileged EXEC mode.

Step 4

Router# copy running-config

startup-config

(Optional) Saves configuration changes to NVRAM.

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

information on alarms and alarm definitions, refer to the “Alarm Troubleshooting” chapter of the

Cisco ONS 15454 Troubleshooting Guide, or the Cisco ONS 15454 SDH Troubleshooting Guide.
