To use this command, you must be in a user group associated with a task group that includes the proper task IDs. For detailed information about user groups and task IDs, see the Configuring AAA Services on Cisco IOS XR Software module of the Cisco IOS XR System Security Configuration Guide.

The DWDM controller supports two loopback operation modes for diagnostic purposes: internal and line. The terminal (internal) loopback mode allows the received data from the Layer 2 Framer (for example, a SONET/SDH framer for POS or Ethernet MAC for 10GE) of the PLIM to be looped back to the ingress side of the Framer. This allows the packets to be looped back to the PLIM. The line loopback mode allows the received trunk/DWDM line Rx to be connected to the trunk/DWDM line Tx towards the line. This is used for line diagnostics.

Examples

In the following example, all packets are looped back to the DWDM controller:

RP/0/RP0/CPU0:router(config)# controller dwdm 0/0/0/0

RP/0/RP0/CPU0:router(config-dwdm)# loopback internal

RP/0/RP0/CPU0:Router(config-dwdm)# pm 15-min otn report esr-pm-fe enable

Command	Description
show controller dwdm pm otn	Displays performance measurement information for the OTN layer.

pm otn threshold

To configure performance monitoring thresholds on the optical transport network (OTN) layer, use the pm otn threshold command in DWDM configuration mode. To disable TCA reporting, use the no form of this command.

pm {15-min | 24-hour} otn threshold otn-parameter threshold

no pm {15-min | 24-hour} otn report otn-parameter threshold

Syntax Description

15-min	Configures performance monitoring thresholds for 15-minute intervals.
24-hour	Configures performance monitoring thresholds for 24-hour intervals.
otn-parameter	Specific parameter for which to configure the threshold. OTN parameters can be as described in pm otn report.
threshold	Threshold for the performance monitoring parameter.

Defaults

No thresholds are configured.

rx-los-threshold

To configure the transponder receive power threshold on a OC-768c/STM-256c DWDM controller, use the rx-los-threshold command in DWDM configuration mode. To return the transponder receive power threshold to its default value, use the no form of this command.

rx-los-threshold power-level

no rx-los-threshold power-level

Syntax Description

power-level

Receive power level in units of 0.1 dBm. Values can range from -200 to 0, which corresponds to a LOS threshold range of -20 dBm to 0 dBm.

Defaults

power-level: -18 dBm
