Cant configure LAG Interface to have Trunk to Aruba Switch

[RolandBaumgaertner72]

Hi,

I have a new FG50G with 7.4.8 and I created on the Web GUI a LAG Interface to connect lan1 and lan2 to port 1/1/1 and 1/1/2 of aruba6000 Switch. Under the LAG Interface I created different Vlans with DHCP. Connecting to the aruba I dont get automatically an IP, also on the Web Gui, the LAG and the Vlans show Link Down.

I connected both correctly and the Aruba shows VLANs on the Aruba CX 6000 are up and assigned correctly to the LAG so that the failure has to be on the FG side. I deleted the config and started new, creating the LAG Interface with CLI but when I configure and type NEXT, I get a a failure:

Attribute 'vdom' MUST be set. Command fail. Return code 1

I dont use a vdom (FGT50G-7.4.8-FW-build2795-250523:opmode=0:vdom=0:user=admin)

Is this a limitation on the FG model or my FortiOS so that I cant create a LAG Interface?

Thanks and regards,

hi,

by default the vdom should be root , when needed to be assigned.
