Further Problem Description
The inventory information is kept in the Entity database and SNMP/MIB infrastructure is responsible to populate that database which has F0 PID and subtype after the system boots up, here these PID and other information are extracted from the module’s IDPROM. Here it is where issue occurs, the infra code is updating F0 Entity Database while IDPROM is not initialized. Therefore, software looks up Entity table with unknown, which results is "PID: ASR1000-FP-UNKNOWN".
