13.13 Monitoring the data traffic
The device lets you forward data packets that pass through the device to a destination port. There
you can monitor and evaluate the data packets.
The device provides you with the following options:

Port Mirroring
13.13.1 Port Mirroring
The Port Mirroring function lets you copy data packets from physical source ports to a physical
destination port.
You monitor the data traffic on the source ports in the sending and receiving directions with a
management tool connected on the destination port, for example an RMON probe. The function has
no affect on the data traffic running on the source ports.
Figure 48: Example
On the destination port, the device only forwards the data packets copied from the source ports.
Before you switch on the Port Mirroring function, mark the checkbox Allow management to access the
device management via the destination port. The device lets users access the device management
via the destination port without interrupting the active Port Mirroring session.
Note: The device duplicates multicasts, broadcasts and unknown unicasts on the destination port.
The VLAN settings on the destination port remain unchanged. Prerequisite for access to the device
management on the destination port is that the destination port is a member of the device
management VLAN.
