Intelligent Traffic Mirroring
Cisco SCE Connectivity
Traffic mirroring is implemented by sending the mirrored packets over a designated VLAN through a
predefined link of the Cisco SCE platform. The link that has been defined for traffic mirroring can be
either used exclusively for this purpose, or it can be one of the traffic ports, in which case the Tx capacity
of the link will be shared between the original egress traffic and the mirrored traffic.
The direction of the flow is preserved when mirrored, so traffic that is received on the subscriber
interface on either link is sent over a VLAN on the network interface over this predefined link. And
traffic that is received on the network interface on either link is sent over a VLAN on the subscriber
interface over this predefined link. The mirrored traffic does not return to the Cisco SCE platform.
Note
Enabling traffic mirroring is expected to impact the Cisco SCE performance due to the excessive
processing associated with it; the actual figure depending on the amount of the mirrored traffic. It is
recommended that you monitor Cisco SCE platform performance when enabling this capability.
