7.2 Circuit Properties
•
# of VLANS—(Future use) The number of VLANs used by an Ethernet circuit.
•
# of Spans—The number of internode links that constitute the circuit. Right-clicking the column
shows a shortcut menu from which you can choose Span Details to show or hide circuit span detail.
For each node in the span, the span detail shows the
node/slot (card type)/port/virtual container
.
•
State—The circuit state; for details, see the
“7.2.3 Circuit States” section on page 7-7
.
The Filter button allows you to filter the circuits in network, node, or card view based on circuit name,
size, type, direction, and other attributes. In addition, you can export the Circuit window data in HTML,
comma-separated values (CSV), or tab-separated values (TSV) format using the Export command from
the File menu.

ONS 15600 SDH Circuit Window in Network View
The Circuit Filter feature allows you to reduce the number of circuits that appear in the Circuits window.
You can specify certain filter criteria, such as name, direction, and state; only the circuits that match the
criteria will appear in the Circuits window.
Note
You cannot set up low-order circuits to terminate on an ONS 15600 SDH node. However, you can create
both high-order and low-order circuits that have an ONS 15454 SDH source and destination with an
ONS 15600 SDH as a pass-through node. For information, see the
“7.18 Low-Order Traffic Routing
over an ONS 15600 SDH Hub Node” section on page 7-27
