Port Mirroring#
Port mirroring replicates a network's traffic to a VM NIC, allowing packet analysis for monitoring or diagnostics.
To Configure Port Mirroring#
- Enable Port Mirroring in the network settings.
- Select North/South - to copy packets that traverse the network router.
- Select East/West* - to copy packets that traverse the router AND all intra-network packets.
* East/West port mirroring is typically only recommended as a temporary setting for diagnostics purposes; using it for long durations can impact performance as it replicates all network traffic. {.is-warning}

- (Re)boot the VM.
- Operating system/application software of choice can be used in the VM for packet analysis.
