NOTE
Disabling of the auto cross-over function will require
crossed Ethernet cables for daisy-chaining the options.
12-93 Cable Error Length
Range: Function:
0* [0 -
65535 ]
If Cable Diagnostics is enabled in EN-90 Cable
Diagnostic, the built-in switch is possible via
Time Domain Reflectometry (TDR). This is a
measurement technique which detects common
cabling problems such as open circuits, short
circuits and impedance mismatches or breaks in
transmission cables. The distance from the
option to the error is displayed in metres with
an accuracy of +/- 2m. The value 0 means no
errors detected.
12-94 Broadcast Storm Protection
Range: Function:
-1
%*
[-1 -
20 %]
The built-in switch is capable of protecting the
switch system from receiving too many broadcast
packages, which can use up network resources.
The value indicates a percentage of the total
bandwidth that is allowed for broadcast messages.
Example:
The “OFF” means that the filter is disabled - all
broadcast messages will be passed through. The
value “0%” means that no broadcast messages will
be passed through. A value of “10%” means that
10% of the total bandwidth is allowed for
broadcast messages, if the amount of broadcast
messages increases above the 10% threshold, they
will be blocked.
12-95 Broadcast Storm Filter
Option: Function:
Applies to 12-94 Broadcast Storm
Protection; if the Broadcast Storm
Protection should also include
Multicast telegrams.

12-98 Interface Counters
Range: Function:
4000* [0 - 4294967296 ] Read only. Advanced Interface
counters, from built-in switch, can be
used for low-level trouble-shooting,
The parameter shows a sum of port 1
+ port 2.
12-99 Media Counters
Range: Function:
0* [0 - 4294967296 ] Read only. Advanced Interface counters,
from built-in switch, can be used for low-
level trouble-shooting, The parameter
shows a sum of port 1 + port 2.
