WHAT IT DOES

What bounce_interface does on HPE Aruba Networking Central MCP Server

AI agents invoke bounce_interface to trigger actions in HPE Aruba Networking Central MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why bounce_interface needs a policy

'Bouncing' an interface is a standard network operations term meaning to shut down and bring back up a port or interface. This is an Execute-level action (triggers an external operation on network hardware) with high severity because misuse could disrupt network connectivity for potentially many users or devices connected through that interface. Confidence is moderate due to empty description.

From the tool's definition Tool name 'bounce_interface' — empty description. 'Bounce' in networking means to disable and re-enable a network interface, which is an operational action that disrupts active traffic on that interface.
