Fortigate 100D as Cisco switch port aggregation

[rohitchoudhary1978]

Hi, Please help me using my fortigate 100D as aggregate switch just as we do in Cisco layer 2 switch as below :

interface GigabitEthernet1/0/33  switchport trunk native vlan 400  switchport trunk allowed vlan 2,3,400  switchport mode trunk  switchport nonegotiate  channel-protocol lacp  channel-group 11 mode active ! interface GigabitEthernet1/0/34  switchport trunk native vlan 400  switchport trunk allowed vlan 2,3,400  switchport mode trunk  switchport nonegotiate  channel-protocol lacp  channel-group 11 mode active

and

interface Port-channel11  switchport trunk native vlan 400  switchport trunk allowed vlan 2,3,400  switchport mode trunk  switchport nonegotiate

I tried to do it as creating new interface 802.3ad aggregate with 2 ports but even after applying and enabling those ports, new interface shows down.  I have no idea if it is supported on FGT 100D.

Please help

Regards

Rohit K

FortiGate doesn't do L2 switching like those switches do. And it doesn't have concept of native vlan or access port. So you can't connect "VLAN 400" to non-tagged interface. 

You can still configure aggregated interfaces with LACP to connect to other switches/routers then put "tagged" VLANs on it. That part should come up. Share us your current config if that part doesn't come up.
