Configured Operation: The operation to be performed with the Configured
SW File when the SU is connected, as well as after each reset: Null (do not
load), Load (load to Shadow), Run from Shadow or Set as Main.
SW Download Status: The status of the last SW download operation (or
None).
SU IDU Type: Basic or IDU-NG-4D1W
Number of Gateways: The number of Gateways connected to the SU
(including IDU-NG-4D1W, if exists).
Service Fault Status: OK or reason for denying services to the SU. The
reason can be:

NOTE
Another loop avoidance mechanism that is transparent to the operator is performed by the NPU:
The NPU scans packets received from the network (DATA port) and verifies that the SRC MAC in
the received packet does not match any of the addresses in the NPU's bridging table. If there is a
match it means that the source MAC address of the message received from the network side is
identical to a MAC address of a device behind one of the SUs served by the Base Station. In case
of a match, the NPU discards all packets designated to the device with this MAC address, until it's
aging time expires.

Summary Information:
Total Number of SUs: The total number of SUs in the database (including
connected and pre-configured SUs)
Total Connected SUs
SUs Connected to AU Slot N, where N=1-4, 7-9.

Loop problem. A loop was detected on the Ethernet side of the SU.
rbNetworkingError Trap will be sent, and services to this SU will be
denied until resetting the SU from the network (NPU) side (provided the
problem no longer exists). The problem is detectable through periodical
(every 5 seconds) transmissions to the Ethernet link of SNAP packets
with "AA AA 03" in the header, and the destination MAC address is
00:10:E7:00:00:01. If the SU receives this packet from the Ethernet, it
means that there is a loop and the SU will send an appropriate
message to the NPU.
Duplicate SU Name: The SU Name is already in use by another SU.
rbSuDuplicateName Trap will be sent and services to the SU will be
denied until another unique name is configured for the SU (see also
Section 4.9.6.3.1.1).
