In-band management IP addresses are an alternative to reserved HA management interfaces, and do not require reserving an interface exclusively for management access. They can be added to multiple interfaces on each cluster unit.
The in-band management IP address is accessible from the network that the cluster interface is connected to. It should be in the same subnet as the interface that you are adding it to. It cannot be in the same subnet as other interface IP addresses.
In-band management interfaces support ping, HTTP, HTTPS, and SNMP administrative access options.
Primary and secondary units send packets differently from an interface with a management IP address configured:
On the primary unit, packets are sent to destinations based on routing information.
On secondary units, packets can only be sent to destinations with the same management IP address segment.
In-band management IP address configuration is not synchronized to other cluster units.
