I've recently adquired 2 aruba switches 3800 series model JL076A. I've stacked them and interconcted to HA FOrtinet 500D cluster.
I've created some vlans in order to separate broadcast traffic between offices.
I can ping all interfaces and hosts from the switch, but I've realized that the ping from 1 host on vlan SALES can't ping a host in vlan MARKETING.
18.104.22.168 - cluster Fortinet 500D (interfaces 1/47,1/48,2/47,2/48)
A pc connected to 1/9 with ip 22.214.171.124 is able to ping 126.96.36.199 but it can't ping a pc in port 1/15 with ip 188.8.131.52. both pcs have GW the ip of the switch (184.108.40.206 and 220.127.116.11 respectively)
Can anyone help me?
Here is the config.

I think you have to add routes between those two subnets in the Fortinet cluster since the routing is being handled by the FW.
I wonder if you could provide us with the routing table just to confirm this

So the traffic between departments is kept in the switch to avoid floadding the Fortis. Only especific traffic going to the internet will be sent to the gateway.
So the stack is in charge of interconnect the vlans.
But, why is not working??
