Port Mirroring
Information on port mirroring
Data loss due to different data rates
If the maximum data rate of the mirrored port is higher than that of the monitor port, data
may be lost. The monitor port then no longer reflects the sequences on the mirrored port.
Port mirroring does not return a 1:1 representation of the network traffic. Bad frames, for
example, are discarded when they are received and are not forwarded via the mirror port.
Configuration for mirroring ports
The "Mirroring Configuration" screen appears if you click the "Mirroring" menu item.
Figure 4-51 Mirroring Configuration
With this check box, you can restrict communication via the monitor port.
● Enabled
The monitor port is taken out of normal frame switching.
You cannot configure or run diagnostics of the device, for example using WBM or CLI, via
the monitor port.
● Disabled
Communication via the monitor port is unrestricted.
You can use WBM, CLI and SNMP via the monitor port.
This option is enabled when the module ships.
