Delete Routers Permanently

If you delete a router on the Available Interfaces, the router is deleted from the system permanently. The deletion removes the router, the related historical data, interfaces, CVIs, and traps. The deletion also affects any aggregations, views, and reports that previously included the router interfaces.

Follow these steps:

1. Verify that the router is no longer sending flows to CA Network Flow Analysis.
2. Open the Available Interfaces page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select System: Enable Interfaces in the Administration menu.

      The Available Interfaces page opens.

3. Locate the router and select the check box next to it.
4. Click Delete.

   A confirmation message opens, which asks you to confirm the deletion.

5. Click Yes in the message box.

   The following events result:

   • The confirmation message closes.
   • The router is deleted from the system and from the Available Interfaces page permanently.
   • All related historical data is purged permanently.
   • All related interfaces, CVIs, and traps are deleted.
   • The router is deleted from any related aggregations.
   • The data for the deleted interfaces no longer appears in the NFA console or in reports.

Note: If the router you delete has any active interfaces, a new router can appear if all of the following conditions are met:

• You deleted the original router from the Available Interfaces page.
• You configured interfaces to be enabled automatically: You set the Auto-Enable Interfaces setting to True on the Application Settings page.
• The router interfaces begin to send flow again.

In this case, a new router appears on both the Available Interfaces page and the Active Interfaces page. The new router inherits the current tenant-domain setting of its parent Harvester. Any customized settings for the previous router are lost. If your deployment includes CA Performance Center, the router polls by using the SNMP profiles that are assigned to the Harvester tenant.
