omcipcap

omcipcap is an open-source GPON/XGS-PON OMCI semantic analysis framework for .pcap and .pcapng files.

It complements packet-level inspection tools such as Wireshark by reconstructing protocol-level engineering information from OMCI traffic.

Main features include:

Detect OMCI provisioning failures and error responses
Build and compare MIB snapshots
Analyze Extended VLAN Tagging Operation Configuration Data (ME 171)
Reconstruct T-CONT, GEM Port and Priority Queue relationships
Generate OMCI topology information
Produce structured JSON and Markdown output for automation and AI-assisted analysis
Support vendor-specific Managed Entity definitions and semantic extensions
