how to add ip address on mc-lag trunk

[blackstark]

hello i have 2 switches maged by fortilink 

i have created a layer 2 port-channel (lacp) to my cisco switch . 

i would like to enable layer 3 on this port-channel 

how do i configure an ip address on the fortinet side?

do i use the cli of the fortigate or the fortiswitch?

i just want 1 ip address total on the fortinet side and 1 ip total on the cisco side . was thinking of using a /30 network for transport.

Hi @blackstark ,

I don't think FSW support the routed port like no-switchport feature of cisco. You can create an SVI and set the port connected to the cisco as member of this VLAN.
