Chapter 4 Configuring Interfaces
Configuring the ML-Series POS Interfaces
To configure path alarms as triggers and specify a delay, perform the following steps beginning in global
configuration mode:
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 trigger
defect {all | ber_sf_b3 | encap
| pais | plop | ppdi | pplm |
prdi | ptim | puneq}
Configures certain path defects as triggers to bring down the
POS interface. The configurable triggers are as follows:
• all—All link down alarm failures
• ber_sd_b3—PBIP BER in excess of SD threshold
failure
• ber_sf_b3—PBIP BER in excess of SD threshold failure
(default)
• encap—Path Signal Label Encapsulation Mismatch
failure (default)
• pais—Path Alarm Indication Signal failure (default)
• plop—Path Loss of Pointer failure (default)
• ppdi—Path Payload Defect Indication failure (default)
• pplm—Payload label mismatch path (default)
• prdi—Path Remote Defect Indication failure (default)
• ptim—Path Trace Indicator Mismatch failure (default)
• puneq—Path Label Equivalent to Zero failure (default)
Step 3
Router(config-if)# pos trigger
delay
millisecond
Sets waiting period before the line protocol of the interface
goes down. Delay can be set from 200 to 2000 ms. If no time
intervals are specified, the default delay is set to 200 ms.
Step 4
Router(config-if)# end
Returns to the privileged EXEC mode.
Step 5
Router# copy running-config
startup-config
(Optional) Saves configuration changes to NVRAM.
