FrameAssembly Documentation
Complete syntax specification, frameassembly reverse decompiler reference, stateful TCP flow rules, and Layer 2–7 protocol keywords.
User Guide & Quickstart
Introduction & Overview
What FrameAssembly is, bidirectional .fasm <-> .pcap compilation, and NetOps/SecOps use cases.
Getting Started with FrameAssembly
Installation, your first .pcap in 60 seconds, reverse PCAP decompilation, MAC formats, stateful TCP, and VLAN/QinQ/MPLS.
Practical Use Cases & Cookbook for Network Engineers
Copy-paste recipes for SNMPv3 traps, firewall ACLs, Suricata/Zeek IDS, SAN/TAC sanitization, and reverse PCAP workflows.
Multi-Host Network Topologies & Dual-Stack Scenarios
Multi-hop gateways, VLAN/QinQ trunks, MAC-only L2 switches, and polymorphic IPv4/IPv6 dual-stack flows.
FrameAssembly (.fasm) File Format & Media Type Specification
Canonical text/vnd.frameassembly language specification, lexical rules, and .fasm extension disambiguation.
Layer 2–7 Protocol Reference (81 Protocols)
Layer 2 — Switching, VLANs & Data-Link
ARP, 802.1Q VLAN, 802.1ad QinQ, LLDP, STP/RSTP, LACP, 802.1X EAPOL, and MPLS shim labels.
Layer 3 — Routing, Overlays, Tunnels & VPNs
ICMP, NDP, IGMP, MLD, OSPF, BGP, RIP, PIM, VRRP, HSRP, BFD, GRE, VXLAN, Geneve, IPsec, IKEv2, WireGuard, and OpenFlow.
Layer 4 — Stateful TCP, UDP & Telecom SCTP

Layer 7 — SNMPv1, SNMPv2c & Encrypted SNMPv3
GET, GETNEXT, GETBULK, SET, RESPONSE, TRAP, INFORM, and encrypted SNMPv3 USM (HMAC-SHA256 + AES-128).
Layer 7 — Core Infrastructure, Time, AAA & Flow Telemetry
DNS, mDNS, DHCP/DHCPv6, NTP, PTP, RADIUS, TACACS+, Syslog, NetFlow v5/v9, IPFIX, and sFlow.
Layer 7 — Web, Cloud, Transport Security, VoIP & Remote Access
HTTP/1.1, HTTP/2, gRPC, WebSocket, TLS 1.2/1.3, QUIC, SSH, Telnet, FTP, TFTP, WHOIS, SIP, RTP, RTSP, STUN, and SSDP.
Layer 7 — Mail, Identity, Storage, Databases & Message Brokers
SMTP, IMAP, POP3, Kerberos, LDAP, SMB2/3, NFS, PostgreSQL, MySQL, Redis, Memcached, MQTT, CoAP, and AMQP.
Layer 7 — Industrial Control Systems (ICS) & SCADA/OT
Modbus/TCP, DNP3 (IEEE 1815), Siemens S7comm, OPC UA, BACnet/IP, and EtherNet/IP (CIP).
