Thanks for the response , let me explain the scenario am using fmc 7.4.1 and for trunk config i didn't found actually as i have may be 30 vlans which will traverse from distribution switch to core switch under transparent firewall ftd and didn't found trunk configuration on fmc so that vlan tags can be travel from distribution switch to firewall then to core switch actually core switch is acting as gateway for all vlans, we can't use firewall as gateway.
bridge i already created for distribution switch as ingress and to core switch as egress but since no trunk configuration so multiple vlan cannot travel but if i assigned one vlan its working fine but i want multiple vlan tags should travel with bridge so that core switch as gateway can be used for all users under the transparent firewall.
Regards
