This notification-only object reports the address family, IPv4 or IPv6, of the cluster network interface used for private replication traffic between vCenter HA nodes. Admins use it to correctly interpret the accompanying vmwVchaPrivateAddressAddr value in a trap. For example, vmwVchaPrivateAddressType reading ipv4 tells the admin the private cluster network address reported alongside it should be read as an IPv4 address.
