The message that you get regard the redondancy for the service console. How many vNIC (physical network interface) have each of your vSwitch?
To have redondancy you must have 2 service console interface (vswif) on 2 different vSwitch or a vSwitch with 2 pNIC attach to it. This is considere as redondancy by VMware.
