I have two single boards that placed in Chassis with a DTI switch. After creating configures VLAN Ethernet on both boards, I could not ping VLAN IP Address each other using Fabric Interface. Boards can ping by itself and pinging each other by using Base Interface. Can you tell me what I am missing here? What further steps I need to do in order to get VLAN communicate with different board via DTI switch. Thanks, Hoang
