SNMP Studio v1.0

Enterprise SNMP browser for Windows — WPF / MVVM / .NET 8

---

Architecture

SNMP.Core      — Interfaces, models, enums. No external dependencies.
SNMP.Engine    — All SNMP logic: client, negotiation, MIB parsing, translation, export.
SNMP.App       — WPF UI, ViewModels, DI wiring.
SNMP.Tests     — xUnit unit tests for classifier, translator, MIB repo, negotiation.

Key Components

Class	Responsibility
SnmpClient	GET / WALK (GETNEXT + GETBULK) / SET via SharpSnmpLib. Handles v1/v2c/v3.
NegotiationService	Auto-probes v2c → v1 → v3 across candidate communities. Returns a structured report.
MibRepository	Loads RFC ASN.1 MIB files, parses OBJECT-TYPE entries, caches by numeric OID.
OidTranslator	OID → symbolic name + description. Falls back to 80+ built-in standard OIDs. Interprets values (uptime, enums, speeds).
ErrorClassifier	Maps raw exceptions to categorised, user-friendly error messages.
ExportService	CSV / JSON export. Diagnostics ZIP bundle (logs + results + sanitised config — no secrets).
LogService	In-memory log with Info/Warn/Error/Debug levels and event notification.
MainViewModel	MVVM hub. Walk, GET, SET (write-guarded), negotiate, MIB import, printer quick view.

Features

• SNMP v1 / v2c / v3 (MD5, SHA1, SHA256, SHA512 auth; DES, AES128, AES256 priv)
• Auto-negotiate — probes the device to find a working version/community
• MIB Import — load .mib / .my / .txt MIB files from files or folders
• OID Translation — symbolic names + descriptions, 80+ RFC standard OIDs built in
• Human-readable context — uptime formatting, status enums, interface speed, supply levels
• Virtualized results grid — handles thousands of OIDs smoothly
• Write Mode — disabled by default, requires explicit toggle + confirmation
• SET — guarded write with OID / type / value, logged without secrets
• Printer Quick View — one-click query of common printer MIB fields (toner, status, serial)
• In-app diagnostics log — Info/Warn/Error/Debug with clear button
• Export — CSV, JSON, or full diagnostics ZIP bundle
• Cancellation — cancel any in-progress walk instantly
