Delete Routers from the Active Interfaces Page

You can delete a router on the Active Interfaces page. Deleting the router in this way effectively deletes its interfaces so you reclaim the storage capacity that the interfaces used. The router is not deleted from the system entirely.

If you delete a router, its historical data, interfaces, CVIs, and traps are deleted. 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. Disable the router interfaces, if they are not disabled already:
   1. Open the Available Interfaces page:
      • Select Administration from the NFA console menu.

        The Administration page opens.

      • Select System: Enable in the Administration menu.

        The Available Interfaces page opens.

   2. Locate the router by using the Search function or by paging through the table contents.
   3. Select the check box next to the router.

      You can select and disable multiple routers simultaneously. All of the selections must be on the same display page, however. Moving to a different page clears any selections that you made on the previous page.

   4. Click Disable.

      A confirmation message opens, which asks if you want to disable all the interfaces for the router.

   5. Click Yes in the message box.

      The Enabled status is changed to No for the interfaces. New data from the interfaces is no longer collected or shown in reports, but data that is already collected is still available for reports.

   6. (Optional) Update the Enabled value for the router by refreshing the page. For example, press F5, navigate away from the page and back, or perform a new search for the router.
3. Open the Active Interfaces page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Interfaces: Physical & Virtual from the Administration menu.

      The Active Interfaces page opens, which lists the current routers and their active interfaces.

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

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

6. Click Yes in the message box.

   The following events result:

   • The confirmation message closes.
   • The router is deleted from the Active Interfaces page.
   • 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.

   The router is not deleted from the system permanently. If you enable its interfaces and the interfaces begin to send flow, the router reappears on the Active Interfaces page.
