Create Interface Aggregations

Create interface aggregations to combine traffic from two or more interfaces so the traffic is reported together.

For example, suppose that you create aggregations for each of several geographical regions. Operators use the aggregations in reports to review and compare the totals for specific regions. Before you created the aggregations, operators had the following problems:

• Data was scattered throughout reports.
• Values were not totaled by region, so quick overviews and comparisons were difficult to make.
• Operators spent too much time designing specialized reports to collect the data and create the totals needed.

Follow these steps:

1. Display the Aggregations Interface page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Interfaces: Aggregations from the Administration page menu.

      The Aggregation Interfaces page opens and shows the list of current interface aggregations.

2. Click New.

   The page changes to show options for adding an aggregation.

   Select interfaces to add to the aggregation by using any of the following methods:

   • Select routers: Select the check boxes next to one or more router names. You can select one router, multiple routers, or a combination of routers and individual interfaces from any routers that are not selected. When a router has been selected, you cannot select any of its individual interfaces.
   • Select interfaces: Click Expand All or click the arrow icon next to a router name, then select the interfaces from the list. To select all the interfaces for a router, select the check box in the heading row.
   • Filter the list to find routers or interfaces: Filter your view by entering a text string in the Search box, then clicking Search. You can search for a full or partial name or address of a router or interface. The router/interface list is filtered to display matching routers or routers that contain matching interfaces.
   • Filter the list to check your selections: Click Show Selected to filter the view to show only the routers that are selected or that contain selected interfaces. You can combine this function with a search string and with Expand All to locate and review your selections quickly.
3. Specify the following values, then click Save:
   • Routers and/or Interfaces: Select one or more of the routers or interfaces that are listed at the bottom of the page. Your selections are added to the aggregation.
   • Aggregation Name: Specify a name for the aggregation.
   • Description: (Optional) Add a notation to help identify the aggregation.
   • In Speed: (Optional) Specify the inbound speed of the selected interfaces.
   • Out Speed: (Optional) Specify the outbound speed of the selected interfaces.

     If you do not specify the In speed and Out speed, both values are set to 0 by default. Inaccurate speeds cause some report results to be inaccurate, such as percentage of utilization.

   • Type: (Optional) Select the mode of interface connection from the Type list, such as WAN or Ethernet.

     If you do not specify the interface type, the type is set to Unknown by default.

   The aggregation is automatically deployed within one minute of creation.
