Circuits can also be created by using the "Create Circuit from Topology View" option. This option is to help the user to refer to the topological links (TLs) by looking at the Topology view or to use Topology view to select the required TLs rather than using the text based TLs under the Create Circuit option. Globally Excluded nodes and links will not be shown for circuit creation.
To create circuit from Topology view, do the following steps:
Click Configuration > Layer 1 > Create Circuit From Topology View. The Create Circuit From Topology View page is displayed.
Select or enter the details for Common Circuit Info, Source Info, and Destination Info depending upon the type of circuit to be created. For more details refer topics under section Create P2P/MEP circuits.
Auto Path option creates the shortest path between Source node and Destination node automatically.
Select the check box if you want find path automatically. Two new options are displayed, Disjointedness and No Of Path.
To create a circuit in which the trunks are not repeated between the source and destination node, do the following steps:
Click Link Diverse option in the Disjointedness drop-down menu.
Select the No of Path desired between source and destination node.
Click Find Path. The shortest path is displayed under the Topology View tab.
To create a circuit in which the work and protect path do not share same SRLG IDs, do the following steps:
Click SRLG Diverse option in the Disjointedness drop-down menu. By default the Class Of Service becomes protected.
Click Find Path. The circuit with work and protect path is displayed under the Topology View tab.
Under Constraints, select the constraints to include or exclude the nodes/links in the work and protect paths of the circuit being created.
Select the check box against Add Include/Exclude Constraints. The topology view will be displayed.
Select the radio button against Include Nodes/Link to include the selected node/link under Work Path. Select the desired Node/TL in the topology view. If the TL is selected, then TL direction window will be displayed. Click OK to confirm.
Click Done next to the Include Nodes/Link in the left pane. The message Include Constraints Added Successfully for WORK_PATH is displayed.
Select the radio button against Exclude Nodes/Link to exclude the selected node/link under Work Path. Select the desired Node/TL in the topology view. If the TL is selected, then TL direction window will be displayed. Click OK to confirm.
Click Done next to the Exclude Nodes/Link in the left pane. The message Exclude Constraints Added Successfully for WORK_PATH is displayed.
Similarly include and/or exclude the nodes/links for the protect path also.
The nodes/links that are included or excluded in the circuit will be displayed in different colors. The legends can be viewed by clicking on next to the Add Include/Exclude Constraints.
Click Show Constraints link to view the constraints. Inclusion Exclusion Constraint window is displayed.
If you want to remove the constraint select the constraint and click Remove.
Under Route Creation, select the check box for Start with Topology View option and click Start Route Creation. The graphical view is shown at the right side of the window. The Topology View is displayed with the source node in black color and destination node in gray color. The following figure shows the trunks associated source node being highlighted in pink:
You have to manually select the work path from source to destination. The user can select the desired work path in the network.
Select the desired out-going links in the Topology View associated with the source node. The node will get added automatically in the graphical view. The out-going links associated with the added node is highlighted in pink color.
Repeat above step until the destination node is reached.
Click and select Protect mode from the drop-down menu to add protect path.
Check the Enable Link selection from Topology View option.
Select the desired out-going link to add the protect path to the desired work path or the segment of the work path in the Topology View.
Click Protect. The protect path will get added automatically in the graphical view. The protect path is designated by dotted line in the graphical view.
To add a protect continue path, select the Protect continue from the drop-down menu.
Select the Create option. The circuits data will be planned and it will be stored in the NMS database OR Select the Create & Activate option. The data will be stored on the node as well as the NMS.
Circuits will be in "Pending state" when Create Circuit is opted.
Circuits will be in "Active state" when Create & Activate Circuit is opted.
NOTE: If the drop-down list does not display any customer names, the user can create customer by clicking on the C link available against this field. The Create Customer page is displayed. Refer Manage Customers section for further details.
If the "Enable link selection from Topology View" option is unchecked, the user can select the TLs from Topology view, only in case of those TLs which are not part of the same partition needs to be selected from the Expand button in the Topology View.
Checking the "Enable link selection from Topology View" option disables the Expand button function, but user can still perform all the operations using Topology View.
The Source and the Destination nodes selected can be across different EMS or partitions. To view the shortest path between the source and the destination node, select the source node and the destination node, and then choose the shortest path icon. This will highlight the shortest path. This is applicable for the nodes within the same partition.
On the right pane of Create circuit from Topologyview page, select Miscellaneous tab. Under Remark, the user can add remarks or notes while creating a circuit.
next to the Add Include/Exclude Constraints.
