IPPM enables LTE cards to monitor near-end path PM data on individual synchronous transport signal
(STS) payloads. After enabling IPPM on provisioned STS ports, service providers can monitor large
amounts of STS traffic through intermediate nodes, thus making troubleshooting and maintenance
activities more efficient.
IPPM occurs only on STS paths that have IPPM enabled, and TCAs are raised only for PM parameters
on the selected IPPM paths. The monitored IPPMs are STS CV-P, STS ES-P, STS SES-P, STS UAS-P,
and STS FC-P. To enable IPPM, refer to the Cisco ONS 15600 Procedure Guide.
The ONS 15600 performs IPPM by examining the overhead in the monitored path and reading all of the
near-end path performance monitoring parameters in the incoming transmission direction. The IPPM
process allows the path overhead to pass bidirectionally through the node completely unaltered.
