SD WAN issue

[jensthms]

I was trying to do SD WAN cofiguration in fortinet VM(6.0) in gns3 before going live in production. But i cant add members to SDWAN, it shows error FAILED DEPENDENCY. What could be the reason?. I also checked whether the interface adding is there in any policy. I can add one interface to SDWAN,when adding second one it shows failed dependency error.

Try diagnose sys cmdb refcnt show system.interface.name <interface name>

I also checked whether it is referenced anywhere but cant find anything.

backup your fortigate and use a text editor to scan through the backup text file.

items to look for

- port 9 HA enabled

- ntp setup on interface

- user that has the interface on it's gui defined

Possible suggestion:

Add port2 to the SDWAN by itself and save that cfg then load an unencrypted backup copy into a text editor and add port3 to the SDWAN members.  Load that back into the fgt vm - try to monitor the console output while it is booting and/or perform diagnose debug config-error-log read at the CLI after you gain access the console.

The above method is ugly in my opinion, but may work.  I recall an old bug from the 4.3/5.0 days where just doing something in the GUI causes certain interfaces to "become dependence".  That said, as a suggestion it maybe remotely possible that this problem is browser related - try using a different browser.
