822 | Port Monitoringw w w . d e l l . c o m | s u p p o r t . d e l l . c o m 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 L2VLAN. Monitored links are configured in two source sessions shown with orange and green circles. Eachsource session uses a separate reserved VLAN to transmit mirrored packets (mirrored source-sessiontraffic 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 inthe local network. Two destination sessions are shown: one for the reserved VLAN that transportsorange-circle traffic; one for the reserved VLAN that transports green-circle traffic.Figure 38-9. Remote Port MirroringConfiguring Remote Port MirroringRemote port mirroring requires a source session (monitored ports on different source switches), a reservedtagged VLAN for transporting mirrored traffic (configured on source, intermediate, and destinationswitches), and a destination session (destination ports connected to analyzers on destination switches).Configuration NotesWhen you configure remote port mirroring, the following conditions apply:Reserved VLANMonitored VLANsMonitored Traffic withReserved VLAN Tag
