Two NIOS-X Servers can be added to an HA (High Availability) group. In case one NIOS-X Server is down, the second NIOS-X Server can take over DHCP lease management without causing downtime. High Availability can be configured as Active/Active, Active/Passive, Advanced Active/Passive or Anycast. For conceptual information, see High Availability for DHCP.

To view the list of HA groups, complete the following:

  1. From the Infoblox Portal, click Configure > Networking > IPAM/DHCP > HA Groups.

  2. The application displays the following information:

  • NAME: Displays the name of the HA group.

  • DESCRIPTION: Displays additional information about the HA group.

  • HA CONFIGURATION: Displays whether the configuration is Active/Active, Active/Passive, Advanced Active/Passive, or Anycast.

  • SERVICE INSTANCE 1: Displays the service instance associated with the HA group.

  • SERVICE INSTANCE 2: Displays the service instance associated with the HA group.

  • HA Status: Displays the following status:

    • Ok

    • failure

    • degraded

    • intermediate

    • unreachable

    • unknown

If a NIOS-X server is disconnected from the Infoblox Portal, the status is shown as degraded.

You can also perform the following in this tab:

  • Click ☰ to select and reorder the columns to be displayed on the interface.

The State can have the following values: ready, waiting, terminated, syncing, passive-backup, partner-down, load-balancing, backup, hot-standby, down, unreachable or unknown. If you do not want to view the details in the right panel, click info_pane-20240912-051742.png .
