The Circuits tab displays information about network circuits including specific low-order circuits and
tunnels, high-order circuits, virtual concatenated (VCAT) circuits, aggregation points, and dense wavelength division multiplexing (DWDM) optical channel network connections (OCHNCs), optical channel client connections (OCHCCs), and optical channel trails (OCH trails). Not all circuit can be created on all platforms.
Circuit information includes status, state, source and destination node, slot, and port. You can view the
Circuits tab in all views. The Scope field expands or decreases the scope of the circuits shown, for example, in card view you can change the scope to node or network so that you can view all node or network circuits.

Displays the name of the circuit. The circuit name can be manually assigned or automatically generated.

For the ONS 15454 SDH, circuit types are HOP (high-order path circuit), LOP (low-order path circuit), VCT (VC low-order tunnel), VCA (VC low-order aggregation point), HOP_v (high-order VCAT circuit), and LOP_v (low-order VCAT circuit).
For the ONS 15600 SDH, the circuit type is HOP (high-order path circuit). LOP (low-order path circuit) is supported only when the ONS 15600 SDH is a pass-through node.
For DWDM circuits, circuit types are OCHNC, OCHNC DCN, OCHCC, and OCHTRAIL.

For the ONS 15454 SDH, the circuit sizes for low-order circuits are VC11 (with XC-VXC-10G card only), VC12, and VC3. High-order circuit sizes are VC4, VC4-3c, VC4-4c, VC4-6c, VC4-8c, VC4-16c, and VC4-64c. OCHNC sizes are Equipped not specific, Multi-rate, 2.5 Gbps No FEC (forward error correction), 2.5 Gbps FEC, 10 Gbps No FEC, and 10 Gbps FEC. High-order VCAT circuits are VC4- nv and VC4-4c- nv and low-order VCAT circuits are VC3- nv, where n is the number of members.
For the ONS 15600 SDH, the high-order circuit sizes are circuit size are VC3, VC4, VC4-4c, VC4-8c, VC4-16c, or VC4-64c. ASAP optical ports also allow circuit sizes of VC4-2c and VC4-3c.
OCHNC, OCHCC, and OCH trail sizes are Equipped not specific, Multi-rate, 2.5 Gbps No FEC, 2.5 Gbps FEC, 10 Gbps No FEC, and 10 Gbps FEC.

(DWDM circuits only) Displays the OCHNC wavelength.
|
|
Displays the circuit direction, either two-way or one-way.
|
|
(DWDM circuits only) The line direction of the OCHNC, OCHCC, or OCH trail, either Side B to Side A or Side A to Side B. If the direction is Side A to Side B, the channel exits from the node through the LINE-TX port of the Side B OSC-CSM, OPT-BST-E, OPT-BST-E, or OPT-AMP-17-C card, named the Side B Side Card by Cisco Transport Planner (typically these cards are hosted in Slot 17). If the direction is Side B to Side A, the channel exits from the node through the LINE-TX port of the Side A OSC-CSM, or OPT-BST, OPT-BST-E, or OPT-AMP-17-C card, named the Side A Side Card by Cisco Transport Planner (typically these cards are hosted in Slot 1).

Displays the circuit source in the format: node/slot/port “ port name” /virtual container/tributary unit group. (The port name appears in quotes.) Node and slot always appear; port “port name”/virtual container/tributary unit group might appear, depending on the source card, circuit type, and whether a name is assigned to the port. If the IEEE 802.17 Resilient Packet Ring (RPR) mode is enabled, the port will appear as pRPR East or pRPR West.
If the circuit is a concatenated size (VC4-2c, VC4-4c, VC4-8c, etc.), VCs used in the circuit are indicated by an ellipsis, for example, VC4-7..9 (VCs 7, 8, and 9) or VC4-10..12 (VC 10, 11, and 12). Note the following:
• |
If the port is on an ONS 15600 SDH ASAP card, the circuit source contains information about the pluggable interface module (PIM) and pluggable port module (PPM), in the format PIM-PPM-port_number. |
• |
If the port is on an ONS 15454 SDH MRC-N card, the port format is PPM-port_number. |
|
|
Displays the circuit destination in same format as the circuit source.
|
|
Displays the number of VLANs used by an Ethernet circuit.
|
|
Displays the number of internode links that constitute the circuit. Right-clicking the column displays a shortcut menu from which you can choose to show or hide circuit span detail. If Span Details is checked, the column name changes to “Spans.” This column displays all circuit span information.
|
|
|
|
Identifies whether or not a port on the circuit is in loopback.
|
|
|
|
Displays the Edit Circuits dialog box to edit the circuit highlighted in the Circuits table.
|
|
Deletes the circuits highlighted in the Circuits table. Do not delete more than 28 circuits at a time.
|
|
Displays the Circuit Filter dialog box to filter the display of circuits on the Circuits tab.
|
|
Displays the Search dialog box to search for circuits based on specific search criteria.
|
|
In node view, choose Network to display network circuits. In card view, choose Node to display node circuits or Network to display all network circuits.
|
|
Turns the filter on or off. CTC retains that last filter activation setting. For example, if you turn the filter on and then log out, CTC keeps the filter active the next time you log in.
