Technical Tip: Changing interface type from 'Redundant' to 'Aggregate'

[nevan]

Description	This article will describe the way to change the interface type from redundant to the interface type aggregate.
Scope	FortiGate.
Solution	It is not possible to change an interface type after creation from the GUI or CLI in FortiGate. The interface can be deleted and recreated, but this may be a time-consuming task if the interface has are many references and dependencies. CLI: config system interface     edit "INT-TST"         set vdom "root"         set type redundant         set member "port6" "port7" "port8" "port9" "port10"     next end Instead of deleting and recreating the interface, the type can be changed by loading a modified configuration backup, but this requires downtime and should be considered a maintenance task. As part of restoring the configuration, the unit will reboot. Reboot times are platform-dependent. Download the current configuration file and save it. Change the configuration manually by opening the config file in a text editor such as Notepad. config system interface     edit "INT-TST"         set vdom "root"         set type aggregate         set member "port6" "port7" "port8" "port9" "port10"     next end Upload the modified configuration file to FortiGate. Note this will cause the firewall and any connected HA cluster members to reboot. Once uploaded successfully, the configuration will be changed, and the interface type will be set as aggregate.
