Aggregate links

Link aggregation enables you to bind two or more physical interfaces together to form an aggregated (combined) link. This new link has the bandwidth of all the links combined. If a link in the group fails, traffic is transferred automatically to the remaining interfaces.

Note

Link aggregation is only available in FortiAnalyzer models 2000E and higher and VMs.

To configure aggregate links:
  1. Go to System Settings > Network.
  2. In the Interface toolbar, click Create New. The Create New Interface page is displayed.
  3. In the Name field, enter a name for the interface.
  4. In the Members field, select the ports you want to include in the aggregate.
  5. In the IP Addess/Netmask field, enter the IP address for the aggregate link.
  6. In the Administrative Access field, select the access protocol.
  7. In the IPv6 Administrative Access area, select the access protocol.
  8. Set the LACP Speed to Slow or Fast.
  9. In the Minimum Links Up field, enter the number of aggregated ports that must be up.
    Note

    You must enter a minimum value of 2 for the aggregate links to work.

  10. Set Minimum Links Down to Operational or Administrative.
  11. In the Links up Delay, set the number of milliseconds to wait before considering the link is up.
  12. Click OK.

After the aggregate links are configured, log into FortiGate and go to Network > Interfaces, and configure an aggregation interface. For information, see Aggregation and redundancy in the FortiOS Administration Guide.

To enable the interface with the GUI:
  1. Go to System Settings > Network.
  2. In the Interface pane, double-click the aggregate interface to edit it. The Edit System Interface window opens.
  3. Set the Status to Enable.
To enable the interface with the CLI:

# config system interface

(interface)# edit Aggregation1

(Aggregation1)# set status up

(Aggregation1)# end
