Chapter 6 Configuring POS on the ML-Series Card
Configuring the POS Interface
Configuring SONET Alarms
All SONET alarms are logged on the Cisco IOS CLI by default. But to provision or disable the reporting
of SONET 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 6-8.
Configuring SONET 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
| pplm | prdi | ptim | puneq |
sd-ber-b3 | sf-ber-b3}
Permits console logging of selected SONET 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.
