HP 5820X Switch - Configuring Traffic Mirroring; Mirroring Traffic to an Interface

189
Configuring traffic mirroring
Traffic mirroring is the action of copying the specified packets to the specified destination for packet
analyzing and monitoring.
You can configure mirroring traffic to an interface or to the CPU.
• Mirroring traffic to an interface: copies the matching packets on an interface to a destination
interface.
• Mirroring traffic to the CPU: copies the matching packets on an interface to a CPU (the CPU of the
device where the traffic mirroring-enabled interface resides).
To configure traffic mirroring, you must enter the view of an existing traffic behavior.
NOTE:
In a traffic behavior, the action of mirroring traffic to an interface and the action of mirroring traffic to
a CPU is mutually exclusive.
