Remote Port Mirroring Example
Remote port mirroring uses the analyzers shown in the aggregation network in Site A.
The VLAN traffic on monitored links from the access network is tagged and assigned to a dedicated L2
VLAN. Monitored links are configured in two source sessions shown with orange and green circles. Each
source session uses a separate reserved VLAN to transmit mirrored packets (mirrored source-session
traffic is shown with an orange or green circle with a blue border).
The reserved VLANs transport the mirrored traffic in sessions (blue pipes) to the destination analyzers in
the local network. Two destination sessions are shown: one for the reserved VLAN that transports
orange-circle traffic; one for the reserved VLAN that transports green-circle traffic.
Configuring Remote Port Mirroring
Remote port mirroring requires a source session (monitored ports on different source switches), a
reserved tagged VLAN for transporting mirrored traffic (configured on source, intermediate, and
destination switches), and a destination session (destination ports connected to analyzers on destination
switches).
