    Actually LTM sync is little bit differ than other devices, the network part which include ip addresses, vlans, trunks, route,.... is not included in sync process. so you have to do it manually in both units, make sure you are using same name in each node, both should be identical

IP and VLAN information does not sync in HA except the floating IPs. So when you create a new VLAN you have to create on both boxes. Create Self IPs n both boxes. Create Floating IP on one box and status will change to "changes pending" so you can sync floating IPs. The reason is floating IP has to be same but self IPs have to be different on each box. If you don't create VLAN on other box and try to sync the floating IP, F5 will give you errors.
