HA

starboy, that's fine. in order to create a DSC you only need core configurations such as interface/vlan/self IPs and then create your configsync, mirror and failover interfaces etc. See the following link for more help: Creating a basic active-active configuration

Once it's setup you can then start to create objects such as pools/nodes/VIPs etc. and can be synced to peer device.

Hope this helps,
