Parse PAN-OS and Panorama XML or set-format exports into the shared firewall schema. Use when input contains vsys, device-group, security rulebase, address-group, application-default, security-profile-group, set deviceconfig, or XML entry/member elements, including audit, conversion, diff, summary, and explanation tasks.
Use this skill to parse Palo Alto PAN-OS firewall or Panorama configuration exports into the shared vendor-neutral firewall intermediate schema. It primarily targets XML exports and also covers flat set-style output when available, including vsys, device-groups, shared objects, zones, address/service/application objects, security rules, NAT rules, routes, profiles, tags, User-ID references, and system settings.
Panorama inheritance and rulebase placement are critical. Preserve shared/device-group/vsys context, distinguish pre-rules and post-rules, and record unresolved inherited references rather than flattening them silently.
Scope and routing
Use only for PAN-OS or Panorama XML and set-format syntax. Hand off ASA/FTD access-list, nameif, or object network input to parsing-cisco-configs, FortiOS blocks to parsing-fortinet-configs, and Junos hierarchy or set security to parsing-srx-configs. Verify production-bound results against current device documentation and output. Downstream consumers are the audit, conversion, and diff skills.
Input Format
PAN-OS configs come in two formats. Auto-detect which one:
XML format — show running-config, running-config.xml export, or Panorama config
Set format — show config flat output with set <path> <value> lines
Detection: Check if input starts with < or contains XML tags → XML mode. Lines starting with set → set-format mode.
Set-format tokenization: Handle double-quoted strings (preserve as single tokens), [ ] bracket list notation (expand to multiple values), and inline # comments. Example: set deviceconfig system hostname fw1 maps to XML path deviceconfig.system.hostname = fw1.
XML Structure Conventions
PAN-OS XML uses two critical element patterns:
<entry name="..."> — Named objects. Always treat as arrays even when single.
Use findVsysEntries() logic: try each path, collect all vsys entries.
Extraction Pipeline
1. Zones
Path: zone.entry[]
Extract: zone name (from @name attribute), zone type (from child element: network.layer3,
network.layer2, network.virtual-wire, network.tap), interfaces list.
2. Address Objects
Path: address.entry[]
Types — detect by which child element exists:
<sctp><port> → protocol: "sctp" — platform-conditional: valid only on PAN-OS 9.0+ platforms with SCTP security enabled (warn: limited support)
PAN-OS service objects are TCP/UDP (and conditionally SCTP) port objects only. ICMP matching is application-based (the ping/icmp App-IDs), not a service-object protocol. If any other protocol child element appears, capture its XML in residual_raw and add a warning.
Also extract <description> from service objects.
5. Service Groups
Path: service-group.entry[]
Extract <members><member> list.
Also extract <description> from service groups.
6. Applications (Custom)
Path: application.entry[]
Extract: name, description, default port from <default><port><member>.
Port format: tcp/80,443 or udp/53 — parse protocol and port range.
services — <service><member> list (often "application-default")
action — <action> child element name: allow, deny, drop, reset-client, reset-server, reset-both
Preserve drop as action: "drop" (distinct from deny), consistent with references/parsing-patterns.md and the schema. Do not collapse drop into deny. Add a conversion warning only for target platforms that cannot distinguish a silent drop from an explicit deny.
log_start — <log-start>yes</log-start>
log_end — <log-end>yes</log-end>
disabled — <disabled>yes</disabled>
description — <description> text
tags — <tag><member> list
schedule — <schedule> text
source_users — <source-user><member> list (User-ID)
Warn if non-"any" values found: User-ID has no direct equivalent on most platforms
url_categories — <category><member> list
Security profiles — check <profile-setting>. Map PAN-OS profile names to the
security_profiles schema keys (left = PAN-OS XML element, right = schema key):
<group><member> → profile_group name, then resolve from profile-group definitions
<profiles> → individual profiles:
<virus><member> → virus
<spyware><member> → anti-spyware
<vulnerability><member> → idp (PAN-OS calls this Vulnerability Protection / IPS; the schema key is idp)
<url-filtering><member> → url-filtering
<file-blocking><member> → file-blocking
<wildfire-analysis><member> → wildfire
<data-filtering><member> → dlp
9. NAT Rules
Path: rulebase.nat.rules.entry[]
For each rule:
Determine NAT type from <source-translation> and/or <destination-translation> presence
Source NAT:<source-translation> with <dynamic-ip-and-port> (interface or translated-address)
or <static-ip> with <translated-address>
Destination NAT:<destination-translation> with <translated-address> and optional <translated-port>
Both: has both source and destination translation → type: "source-and-destination"
Aggregate-ethernet (ae1): LAG with layer3 IP, MTU, sub-units
Loopback (loopback.N): IP and description
VLAN (vlan.N): IP and VLAN tag
Tunnel (tunnel.N): IP for VPN binding
Derive interface type from name: ae*=lag, loopback*=loopback, tunnel*=tunnel, vlan*=vlan.
Back-populate lag_members on aggregate interfaces after parsing all interfaces.
Subinterface zone inheritance: if a subinterface has no zone but its parent does, inherit the parent's zone.
Path: mgt-config.users.entry[]
Extract: username, SSH public key (ssh-public-key or older public-key), role from permissions (superuser→super-admin, devicereader→read-only, deviceadmin→admin).
Only migrate users with SSH keys; warn about others.
IKE crypto profiles: encryption, integrity, DH groups, lifetime
IPsec crypto profiles: ESP encryption/authentication, DH group (PFS), lifetime
IKE gateways: version (IKEv1/v2), auth method (PSK or certificate), PSK presence (mask the value as "****"), local/peer address, local/peer ID, crypto profile reference, local cert + CA profile
Flag weak algorithms (DES/3DES, MD5, DH group ≤ 5)
Zone protection:network.profiles.zone-protection-profile.entry[]
Syslog:shared.log-settings.syslog.entry[]
Virtual wire:network.virtual-wire.entry[]
16. Application Resolution (L7 → Canonical)
PAN-OS has the richest L7 application model of any firewall vendor. Security policies use
<application><member> to match traffic by application signature, independent of port.
Resolution steps for each application name in a policy:
Service object/group check: If the name matches a service object or service group → promote
to the services array (PAN-OS sometimes places port-based matches in the application field)
Application group check: If the name matches an application-group.entry[] → add to policy's
app_groups array
Custom application check: If the name matches a application.entry[] (custom app) → keep it
as an L7 application reference under applications/apps. Capture its <default><port> definition
as app metadata / a conversion hint (e.g. default_port), but do NOT replace the application with a
service object — a custom App-ID remains an L7 application.
Cross-vendor canonical resolution: Resolve through the app mapping table

application-default service: When a policy sets <service><member>application-default</member>,
PAN-OS uses each application's built-in default port. For the IR, keep services: ["application-default"]
and rely on the apps array for resolution. During conversion to port-based platforms, decompose
each resolved app's default port into explicit service matches.
On policy output: For each resolved app, populate apps array:
{ vendor_name: "ssl", canonical: "https", confidence: 1.0, category: "web" }
Custom applications (application.entry[]): Extract the <default><port><member> list.
Format is tcp/80,443 or udp/53 — parse protocol and port range and attach it as app metadata
(e.g. a default_port field / conversion hint) on the custom app's entry under applications/apps.
Keep the custom app as an L7 application reference; do NOT create a service object or move it into the
policy's services array. Only decompose the default port into explicit service matches during target
conversion when the target platform requires it. Set confidence: 0.9 since custom apps may not have
an exact canonical equivalent.
Unresolvable apps: PAN-OS has 3000+ built-in application signatures. Many are vendor-specific
(e.g., palo-alto-networks, fortinet). For unknown apps, set confidence: 0.0, preserve the
vendor_name, and warn. These will go to residual during conversion.
If a member is itself an application group → recurse
If a member is a custom application → extract its port definition
Store in application_groups with canonical member names.
Mixed groups: If a group contains both L7 apps and port-based services, split them:
L7 apps → application_groups, port-based → service_groups.
17. Multi-vsys
If multiple vsys entries found:
Parse each independently
Tag all policies and objects with _vsys: "vsys1" etc.
Merge into flat arrays
Re-index _rule_index sequentially
18. Residual Config Capture
Capture unhandled configuration sections. In XML mode, serialize unhandled elements back to XML strings. Categorize into: VPN Tunnels, IKE, IPsec Crypto, QoS, DNS Proxy, Shared Objects, PKI/Certificates, Security Profiles, Custom Applications, Policy-Based Forwarding, Panorama Config, Other. Store in residual_raw.
19. Implicit Rules
After parsing all explicit policies, append per-context:
Implicit: Intra-zone Allow — per zone, action: "allow", _implicit: true
(for each zone, src_zones = dst_zones = [zone_name])
Implicit-rule name values (e.g. "default-deny", "Implicit: Default Deny") are free-form labels; consumers must match implicit rules on _implicit: true, never on the name.
Output Format
Present results in the intermediate schema format documented in references/intermediate-schema.md.
Note: schema sections not yet populated by this pipeline (e.g., security_profile_objects, routing_contexts) are emitted empty ([]/{}); any unhandled source constructs are captured in residual_raw rather than dropped.
Full intermediate-schema emission is optional for single live-device work. The complete JSON schema exists primarily for cross-vendor conversion and multi-config diffing. When interpreting or auditing a single live device pulled via the XML API for an ops/audit task, it is fine to reason directly from the XML config and skip full schema emission — extract the sections relevant to the question. Emit the full schema when the parse will feed firewall-config-conversion, firewall-config-diff, or another config for comparison.
Parser Quality Gates
Before returning a parse, run these common quality gates and include the results in the response:
Format and scope detection — report detected vendor, platform family, config format, version clues, virtual context names (VDOM/vsys/logical-system/routing-instance), and whether input appears complete or partial.
Schema conformance — emit the vendor-neutral JSON sections defined in references/intermediate-schema.md; use empty arrays/objects for absent sections rather than omitting expected top-level keys.
Object counts — summarize counts for zones, interfaces, address objects/groups, service/application objects/groups, policies, NAT rules, routes, VPNs, HA, admin users, and residual blocks.
Reference resolution — list unresolved object, service/application, zone/interface, profile, route, VPN, and NAT references with source rule/context where possible.
Ordering preservation — preserve security policy order, NAT order, and route order when relevant. For Panorama, encode the full merged evaluation order (shared → device-group pre-rulebase → local/vsys rulebase → device-group post-rulebase, with nested device-group inheritance) using _rule_index. The schema defines only _rule_index and _vsys for PAN-OS context, so record device-group / pre-vs-post origin in metadata.warnings or residual_raw rather than inventing a context field.
State preservation — preserve disabled/inactive objects and rules, comments/descriptions, tags, schedules/time-ranges, negation flags, logging settings, and profile attachments.
Residual capture — put unsupported or ambiguous source lines/blocks into residual_raw with enough context for manual review. Do not silently drop unknown syntax.
Warnings and assumptions — populate metadata.warnings with parser limitations, partial-input assumptions, ambiguous conversions, and version-specific caveats.
Conversion readiness — if the user asks for migration/conversion, explicitly separate parsed facts from proposed target-platform design choices and call out non-isomorphic features.
A high-quality parse is not just valid JSON: it must make uncertainty visible. Prefer a complete parse with warnings and residuals over a clean-looking parse that hides unsupported constructs.
Analysis Checks
After extraction, run these checks and report findings:
Unused objects — address/service objects not referenced by any policy
Shadowed policies — rules fully covered by earlier rules
Overly permissive — rules with any/any or negate patterns covering everything
Missing logging — permit rules without log-end enabled
Disabled policies — rules with <disabled>yes</disabled>
Duplicate objects — same value, different names
Empty groups — groups with no members
Dynamic groups — flag for manual review (no static equivalent)
User-ID dependencies — rules relying on source-user for access control
URL category dependencies — rules using URL categories for access control
Reference Files
references/config-format.md — PAN-OS XML structure reference
references/fixture-expected-output.json — Expected high-level intermediate-schema output for the minimal fixture
Secret Handling
Never emit secrets raw. IKE/VPN pre-shared keys, routing-protocol authentication keys (BGP/OSPF), and user password hashes must be masked as "****" (or reduced to a presence flag) with a metadata.warnings entry noting the redaction — matching the shared-schema convention ("psk": "****").
Common Pitfalls
Do not collapse Panorama shared, device-group, and vsys scopes without preserving source context.
Preserve pre-rulebase vs post-rulebase order; rule placement changes behavior.
application-default is not a normal service object. Represent it explicitly and warn during cross-vendor conversion.
Application, service, URL category, tag, and profile references can look similar; resolve each against the correct object tree.
Disabled rules, negation, User-ID fields, and dynamic address groups are easy to lose; capture them explicitly or warn.
