Figure 94: Remote Port Mirroring Example Network Topology

In this example:
Interface is a Layer 2 interface and interface
ge-0/0/0
that serve as connections for employee computers.
Interface ge-0/0/10 is a Layer 2 interface that connects to another switch.
VLAN is configured on all switches in the topology to carry the mirrored
remote-analyzer
traffic.
NOTE: The interface connected to the remote monitoring station must be a
member of VLAN
switches between the monitored switch and the monitoring station.
Mirroring All Employee Traffic for Remote Analysis
To configure port mirroring for remote traffic analysis for all incoming and outgoing
employee traffic, perform these tasks:
To quickly configure port mirroring for remote traffic analysis for incoming and outgoing
employee traffic, copy the following commands and paste them into the switch terminal
window:
