How to set dual management port correctly?

Solution

Dual management port is a policy for logging in web UI. When you enable dual management ports, you need to set different IP to controller 1 and 2 so that you can login web UI by these two IPs at the same time. However, when master controller is failed, the IP will not failover since slave controller has its own IP.
Therefore, if you find that you cannot access web UI from IP on the master controller, you can try to access web UI from IP on slave controller no matter the cause is that controller indeed fails or network cable is unplugged.

If you don’t enable dual management ports, management port is available to access only on the master controller. In our design, even there is only one management port IP (on the master controller), this IP will fail over to the slave (alive) controller if the master controller gets failed.
It won’t be an issue if both management ports are connected to the same switch, but make sure both ports are on the same network segment or VLAN.
However, notice that if network cable on management port on the master controller is unplugged, there are no other ways to access web UI since IP will not fail over if just network cable is unplugged.
