You can use port mirroring to analyze network traffic for debugging or troubleshooting purposes. Port mirroring allows you to copy all network packets or specific packets that are seen on the segment port (or an entire segment) to another segment port.
Port mirroring is supported on ENS and Non-ENS for Remote L3 Span session type.
Note: Port Mirroring is not recommended for monitoring because when used for longer durations performance is impacted.
