Edit Circuits

To edit a circuit, do the following steps:

1. Click Configuration > Layer 1 > Circuits and click Manage Circuits. The Manage Circuits page is displayed.
2. Right-click the desired circuit and click Edit circuit. The Edit circuit page is displayed.

   

3. Edit the required fields. For more details of the parameters refer the appropriate topics under Circuits.
   • The Common Details parameters are displayed from the selected circuit.
   • If you want to edit the source end parameters, edit the desired values under Source Info.
   • If you want to edit the destination end parameters, edit the desired values under Destination Info.

     NOTE: The time slots can be edited only for SDH/SONET client ports.

4. The graphical view of circuit is displayed. If you want to edit constraints click Show Constraints. The Inclusion Exclusion Constraints window is displayed. On Inclusion/Exclusion tab the constraints added while circuit creation can be removed. Select the constraint and select Remove. And close the window.

   NOTE: The constraints can be added only while Creating circuits from Topology View.

5. If you want to edit the bulk circuits present in the same path then enable Bulk Edit option and select the following option:
   • Matching Routes: Editing of circuit will be applied for all the circuits with the similar matching route.
   • Matching Route Segment: Editing of circuit will be applied for all the circuits of different routes with common segment ie some part of the route will be shared for different paths. For example, two paths from A-B-C-D nodes and A-B-E-F nodes, since both the paths share same segment A-B, the circuits can be edited for both paths.

     

6. If you want to edit the port of any node in the work path/protect path, do the following steps:
   1. Click Expand. The Out Going Links of <node IP> window is displayed.
   2. Double-click the desired out-going link on different port. The port is changed.
   3. Click Save to save the changes. A success message is displayed.
7. If you want to edit the timeslots of port on any node in the work path/protect path, do the following steps:
   1. Select the desired trunk in the graphical view. The time slot has to be edited in the Properties table.
   2. Click R to refresh the time slot details.
   3. Select the desired time slot.
   4. Click Save to save the changes. A success message is displayed.

      

8. If you want to add protect path to the work path ensure the 'Class of Service' is selected as Protected in Common Circuit Info and perform following steps:
   1. Select Protect Path under All Routes field.
   2. Select the source node.
   3. Click Expand. The out going links present on the node will be listed.
   4. Double-click the desired link.
   5. Click Save to save the changes. A success message is displayed.
9. If you want to remove a node/link on Work/Protect path perform following steps:
   1. Select the desired node/link in the graphical view.
   2. Click Delete. If you delete a node, all the links present on that node will be removed from the path.
   3. Click Save to save the changes. A success message is displayed.

NOTE: Editing of circuits can be done on all NEs wherever bridge and roll capable NEs are available. You can leverage this functionality to perform bridge and roll to prevent a traffic loss. However, depending upon the scenario, the edit circuit may or may not be traffic affecting.

The granularity (Capacity) of the circuit cannot be edited. Any circuits in "Conflict" state needs to be resolved either from TJ5500 or from the Node side to edit the same. After editing the circuits in "Pending" state, you have to manually activate them.

Topological Links in a circuit having same SRLG IDs assigned to them are referred to as SRLG Conflicting TLs. The information of such circuits are displayed under the Miscellaneous tab in Edit Circuit page.
