Traffic Mirroring Overview
Traffic Mirroring Overview
Traffic mirroring is implemented by a QoS policy, which defines certain match criteria to match the
packets to be mirrored and defines the action of mirroring such packets to the specified destination.
Depending on different types of mirroring destinations, there are two types of traffic mirroring:
z
Mirroring to port: The desired traffic on a source port is replicated and sent to a destination port.
z
Mirroring to CPU: The desired traffic on a source port is replicated and sent to the CPU on the LPU
of the port for further analysis.
Remote Traffic Mirroring Overview
Remote traffic mirroring combines traffic mirroring with remote port mirroring to use a remote mirroring
group to mirror local packets matching the specified criteria to the specified destination port on a remote
device.
Remote traffic mirroring is implemented as follows: configure traffic mirroring on the local device to
mirror packets matching certain criteria to an egress port; configure a remote source mirroring group on
the local device and specify the destination port for traffic mirroring as the egress port, so that packets
sent to the destination port by traffic mirroring can be mirrored to the remote device by remote port
mirroring.

By default, the and keyword
is specified. That is, the
relation between the rules in
the class view is logic AND.
This operation leads you to
