3.5.7 Deleting NEs
Note If a CTC-based NE is deleted and then DCC connectivity to the deleted NE is removed, CTM rediscovers
the deleted NE. If DCC connectivity is removed before deleting the NE, CTM does not rediscover the
NE. Therefore, remove DCC connectivity to the NE before deleting the NE from CTM.
3.5.7.2 Deleting Multiple NEs
Step 1 For each NE that will be deleted:
a. In the Domain Explorer tree, select the NE that will be deleted.
b. In the Status tab of the Network Element Properties pane, set the Operational State field to
Out of Service; then, click Save.
Step 2 In the Domain Explorer tree, select again all the NEs that will be deleted. To select multiple NEs, press
and hold down the Ctrl button; then, click each NE that will be deleted.
Step 3 You can delete the selected instance of the NEs or all instances of the NEs:
• Deleting the selected instance of the NE—Only the specific NEs that you selected in the Domain
Explorer tree will be deleted. To delete the selected instance of the NEs, choose Edit > Delete; then,
click Yes in the confirmation dialog box. If the selected NEs are the last instance of the NE, the NEs
are placed in the Deleted Network Elements group.
Note A GNE that has associated subtending NEs cannot be deleted. A subtending NE can be
disassociated from the GNE by removing the NE from the CTM domain or by assigning it
to a different GNE.
• Deleting all instances of the NEs—All NEs in the user domain that have the same NE ID as the NE
being deleted will be deleted. To delete all instances of the selected NEs, choose Edit > Delete All;
then, click Yes in the confirmation dialog box. The NEs are placed in the Deleted Network Elements
group.
Note Both the Delete and Delete All menu options are enabled if at least one of the selected NEs can
be deleted. The confirmation dialog box lists the NEs that can and cannot be deleted.
Note You can use the mouse to drag and drop the selected NEs to the Deleted Network Elements group
only if all the selected NEs can be deleted.
3.5.7.3 Using the prune_ne.sh Script to Remove an Out-of-Service NE from the Database
Note It is recommended that you delete an out-of-service NE from the CTM client (see 3.5.7.1 Deleting a
Single NE, page 3-25 or 3.5.7.2 Deleting Multiple NEs, page 3-26), because doing so does not involve
stopping and starting the CTM server.
