Remote Port Mirroring Example
Remote port mirroring uses the analyzers shown in the aggregation network in Site A.
The VLAN trac on monitored links from the access network is tagged and assigned to a dedicated L2 VLAN. Monitored links are
congured 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 trac is shown with an orange or green circle with a blue border).
The reserved VLANs transport the mirrored trac 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 trac; one for the reserved VLAN that transports green-
circle trac.

Conguring Remote Port Mirroring
Remote port mirroring requires a source session (monitored ports on dierent source switches), a reserved tagged VLAN for transporting
mirrored trac (congured on source, intermediate, and destination switches), and a destination session (destination ports connected to
analyzers on destination switches).
