How Traffic Mirroring Works
Traffic mirroring uses the same capabilities as VAS traffic forwarding, but the traffic does not return to
the Cisco SCE platform.
The following sections explain how traffic mirroring works:

Traffic Mirroring and SCA BB
When traffic mirroring is configured for a certain type of traffic, in addition to all its basic functions, the
SCA BB application decides whether each flow is to be mirrored or not, based on L7 classification.
Traffic mirroring rules are configured through the SCA BB console. These rules map the traffic to be
mirrored and analyzed to the VAS server groups. When a flow is marked for traffic mirroring, the VAS
server group for this flow is selected. If the group includes more than one VAS server, traffic will be
forwarded in such a way that the subscriber load is shared between the servers on the same group.
