Version
9.4.0

You can configure xHA with dedicated managment enabled on both nodes, or without. xHA can be configured with IPv4-only, IPv6-only, or dual-stacked (IPv4 and IPv6 eth0 interface addresses) DNS/DHCP Servers.

xHA with dedicated management enabled requires the configuration of new IP addresses for the Management interface (eth2) and the Services interface (eth0). If the DNS/DHCP Servers are IPv4-only or IPv6-only, only one new address is required for the Services interface when creating a xHA pair. If eth0 is dual-stacked, both a new IPv4 address and a new IPv6 address will be required for the Services interface when creating an xHA pair.

xHA with dedicated management disabled requires only the configuration of new IP addresses on the eth0 interface, which handles both Management and Services traffic. If the DNS/DHCP Servers are IPv4-only or IPv6-only, only one new address is required for eth0 when creating a xHA pair. If eth0 is dual-stacked, both a new IPv4 address and a new IPv6 address will be required for the eth0 interface when creating an xHA pair.

Note: Address Manager v9.4.0 supports xHA on DNS/DHCP Servers running software version 9.2.0 or greater only.
For more information on the prerequisites for creating an xHA pair, refer to Prerequisites for xHA.
Attention:
  • You can't configure interface and network settings of DNS/DHCP Servers that are part of a functioning xHA pair. Configure interface and network settings before creating a high-availability pair.
  • You can't configure interfaces if the DNS/DHCP Server is under Address Manager control. Remove the DNS/DHCP Server from Address Manager control to configure interfaces.
  • You can't configure interfaces if network redundancy (bonding) is enabled. Disable redundancy from the Administration Console to configure interfaces. Disabling bonding will also remove the DNS/DHCP Server from Address Manager control.
