Cisco Cisco Prime Optical 9.6 Prospecto

From the above picture it can be seen that the subnetwork '

TestDwdm

’ is available under

"zoneDWDM" group as well as "WestZoneDWDM"  group.

Note: Duplicate subnetwork is under WestZoneDWDM group as it is unwanted subnet.

We need to delete the subnetwork 'TestDwdm’ from WestZoneDWDM group by logging into the
Oracle DB.

Step1: Select the duplicate subnetwork and click the Edit tab.

Step2: select the Delete option from the Edit menu (Select the duplicate subnetwork-->EDIT--
>DELETE).

In some cases even if you delete the duplicate subnetwork from CPO by the above steps, it will
reappear once you refresh the CPO.

In that case you could try to follow the below steps to delete the subnetwork:

Step1: Open the duplicated subnetwork by double-clicking the subnetwork.

Step2: Select all the nodes under the duplicated subnetwork, then right click and mark the nodes
as out of service.

Step3: Delete the nodes one by one from the Edit tab in CPO.

Note: Don’t select the delete all option from Edit tab, since it will delete the nodes from the active
and duplicate subnetworks.
In some case the above two option will not work and in that case we need to delete the duplicate
subnetwork by logging into the Oracle DB. This is a Known bug and the procedure to clear the
issue is described below by considering the above example as reference.

In the above example we need to delete the subnetwork 'TestDwdm’ from WestZoneDWDM group
by logging into the Oracle DB.

Step1: Log in to the Oracle database.
