Delete Routers from the Active Interfaces Page

You can delete a router on the Active Interfaces page, but leave it in place on the Available Interfaces page. For example, you may want to delete a router in this way to address capacity issues. Later, you can restore the router (but not its historical data) by enabling its interfaces on the Available Interfaces page.

Deleting a router removes its interfaces, CVIs, 15-minute (historical) data, and traps. The deletion also affects any related aggregations, views, and reports.

Note: If you delete the router from the Available Interfaces page, the system has no further record of the router.

Follow these steps:

1. Verify that the router is no longer sending flows to the product.
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 provided the selections are on the same page.

   4. Click Disable.

      A confirmation message opens.

   5. Click Yes.

      The Enabled status for the interfaces changes to 'No.' New data from the interfaces is no longer collected or shown in reports. 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, by pressing F5.
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.

4. Locate the router and select its check box.
5. Click Delete.

   A confirmation message opens.

6. Click Yes.

   The following events result:

   • The confirmation message closes.
   • The router is deleted from the Active Interfaces page and stops consuming capacity.
   • 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.

Note: A router that you delete from the Active Interfaces page reappears if the router interfaces are enabled on the Available Interfaces page and the interfaces begin to send flow again.
