PMI
Default Severity: Not Alarmed (NA), Non-Service-Affecting (NSA)
Logical objects: OCH, OMS, OTS
The Payload Missing Indication (PMI) condition is part of MSTP network-level alarm correlation. It is raised
at the far end when OTS or OMS optical payload is missing due to an LOS, LOS-P, or OPWR-LFAIL alarm
root cause. A single PMI condition is sent when every channel on the aggregated port is lost--that is, when
there are no pass-through channels or active added channels in service.
An LOS, LOS-P, or OPWR-LFAIL alarm on an MSTP circuit causes multiple alarms for each channel. R7.0
correlation simplifies troubleshooting by reporting a single alarm for multiple alarms having one root cause,
then demoting the root alarms so that they are only visible in the Conditions window (with Not Reported [NR]
severity.)
PMI clears when the optical channel is working on the aggregated or single-channel optical port.
Network-level alarm correlation is only supported for MSTP communication alarms. It is not supported for
equipment alarms.
