📖 Detailed Installation Guide →
Run a configurable SNMP agent on UDP 1061 with custom OID values. Perfect for testing SNMP clients without real hardware.
Key features:
- Custom OIDs with any value and type
- SNMPv1/v2c support
- Persistent configuration
- Web-based control
Use case: Simulate devices for NMS development and testing.
Execute SNMP walks against any device with automatic MIB resolution and data export.
Key features:
- Automatic OID → name resolution
- Bulk operations (GETBULK)
- JSON/CSV export
- Walk history
Use case: Test SNMP agent responses, validate walk implementations.
Send and receive SNMP traps with real-time monitoring and MIB-based trap browsing.
Key features:
- Trap Sender (Client): Send v1/v2c traps with custom varbinds
- Trap Receiver (Server): Real-time trap display on UDP 1162
- Trap Library: Browse 24+ available traps from loaded MIBs
- Auto-populate varbinds from library
Use case: Validate trap format/syntax for NMS development.
Upload, validate, and manage MIB files with automatic dependency resolution.
Key features:
- Drag-and-drop upload
- Syntax validation
- Dependency resolution
- Trap enumeration
- Statistics (objects, imports, traps)
Use case: Validate MIBs before deployment, centralized MIB library.
Interactive tree explorer for navigating OID hierarchies and understanding MIB structures.
Key features:
- Dual views: By module or standard OID hierarchy
- Real-time search: Find OIDs by name, numeric OID, or description
- Smart filtering: By module and type (scalars, tables, notifications)
- Tree navigation: Expandable with configurable depth (1-5 levels)
- Details panel: Full metadata, descriptions, varbinds
- Integration: Jump to Walker/Trap Sender with pre-filled data
- State persistence: Remembers your position
Use case: Explore MIB structures, understand OID relationships, find traps.
Manage authentication and system preferences.
Key features:
- Credential management (username + password with strength indicator)
- Auto-start toggles and session timeout (persisted to
app_settings.json) - Export or reset activity stats
- System info (version, author, description)
