GNS3 Node Operations

Manage network device nodes in GNS3 projects. Add devices from templates, control power state, and access consoles for configuration and troubleshooting.

When to Use

• Adding network devices (routers, switches, firewalls) to a lab
• Starting or stopping individual nodes
• Reloading nodes after configuration changes
• Suspending nodes to save state
• Starting or stopping all nodes in a project
• Getting console access information for device configuration
• Isolating nodes for testing without deleting links
