Delete Routers from the System

If you delete a router on the Available Interfaces page, the router is deleted from the system entirely. The deletion removes the router, its configuration information, 15-minute (historical) data, interfaces, CVIs, and traps. The deletion also affects any aggregations, views, and reports that previously included the interfaces.

Note: If the interfaces from the deleted router begin to send flow again, a new router appears on the Available Interfaces page. If the program is configured to enable new interfaces automatically, the new router and interfaces also appear on the Active Interfaces page. The new router inherits the current tenant-domain setting of its parent Harvester. Configuration 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.

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 its check box.
4. Click Delete.

   A confirmation message opens.

5. Click Yes.

   The following events result:

   • The confirmation message closes.
   • The router is deleted from the system, the Available Interfaces page, and the Active Interfaces page.
   • The router configuration information is deleted from the NFA console server.
   • All related interfaces, CVIs, 15-minute (historical) data, 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.
