8.1 Service Mirroring
When troubleshooting complex operational problems, customer packets can be
examined as they traverse the network. One way to accomplish this is with an
overlay of network analyzers established at multiple points of presence, together with
skilled technicians to operate them to decode the data provided. This method of
traffic mirroring often requires setting up complex filters in multiple switches and/or
routers. These are, at best, only able to mirror from one port to another on the same
device.
Nokia Service Mirroring extends and integrates these capabilities into the network
and provides significant operational benefits. Each system can mirror packets from
a defined set of ports to any destination point in the network.
Original packets are forwarded while a copy is sent out the mirrored port to the
mirroring (destination) port. Service mirroring allows an operator to see the actual
traffic on a customer's service with a sniffer sitting in a central location. In many
cases, this reduces the need for a separate, costly overlay sniffer network.
8.2 Mirror Implementation
Mirroring can be implemented on ingress or egress PORTS.
