[ Diagnostics > Ports > Port Mirroring ]
The
Port Mirroring
function lets you copy received and sent data packets from selected ports to a
destination port. You can watch and process the data stream using an analyzer or an RMON probe,
connected to the destination port. The data packets remain unmodified on the source port.
Note: To enable the access to the device management using the destination port, mark the
checkbox
Allow management
in the
Destination port
frame before you enable the
Port Mirroring
function.
Operation
Operation
Enables/disables the
Port Mirroring
function.
Possible values:

The
Port Mirroring
function is enabled.
The device copies the data packets from the selected source ports to the destination port.

The
Port Mirroring
function is disabled.
Destination port
Primary port
Specifies the destination port.
Suitable ports are those ports that are not used for the following purposes:
• Source port
• L2 redundancy protocols
Possible values:
no Port
(default setting)
No destination port selected.
<Port number>
Number of the destination port. The device copies the data packets from the source ports to this
port.
On the destination port, the device adds a VLAN tag to the data packets that the source port
transmits. The destination port transmits unmodified the data packets that the source port receives.
Note: The destination port needs sufficient bandwidth to absorb the data stream. If the copied data
stream exceeds the bandwidth of the destination port, then the device discards surplus data
packets on the destination port.
Secondary port
Specifies a second destination port.
