The IP Interface Settings page lists information about network interfaces configured for the a host. Depending on your host deployment, you may or may not be able to Whether or not you can modify information on this page depends on how your host was deployed. BloxOne supports interface modifications modification of interfaces for the following deployments: BloxOne BloxOne VM, BloxOne BloxOne Appliance, and BloxOne and BloxOne Container. If
If you have multiple network interfaces configured for the a host, you can enable or disable them as well as and set routing priorities by configuring routing metrics. You can also modify the network configuration for physical appliances or and virtual appliances that were deployed through OVA deployments , by using the a downloaded Infoblox image. If you have configured multiple network interfaces on your Kubernetes-based hosts, all the Ethernet ports are will be displayed in on this sectionpage. For information about using multiple interfaces, see Multiple Network Interfaces for Hosts.
You can configure IPv4-only or IPv4/IPv6 dual-stack networks for a host. However, IPv4/IPv6 dual-stack networks are not supported if you plan to enable DNS or DHCP services on the host, IPv4/IPv6 dual-stack networks will not be supported.
On On the IP Interface Settings page of the Edit <Host> wizard, you can view or update IP interface settings, as follows:
1. Select the
...
checkbox of the network interface from the list, and
...
click Edit.
2. In the Edit IP Interface Settings section,
...
specify the following:
Network Interface: Displays the name The names (such as enp1s0 and enp2s0) of the Ethernet ports on the appliance, such as enp1s0 or enp2s0. You can configure up to two network interfaces for the same network gateway. All network interfaces you have configured appear in the table. You cannot modify this field. You can configure up to two network interfaces for the same network gateway.
Interface Type: Displays whether the network interface is WAN or LANWAN or LAN, based on your deployment. You may or may not be able to change the interface type. When your hosts have multiple interfaces, the lowest metric interface will be marked as WAN and as WAN and the rest of the interfaces will be marked as LANas LAN. The interface type you configure here defines the interface binding, also known as the interface label, between the BloxOne service and the interface on which the service runs.
IPv4 MTU: Enter the The maximum transmission unit for the IPv4 network, which is the size of the largest protocol data-unit that can be communicated in a single network-layer transaction. Valid values are Enter a value from 576 to 9001. The default value is 1500.
If you are
...
configuring a dual-stack network for the host, you must set the minimum MTU value for the IPv4 address
...
to 1280
...
; if you do not, the IPv6 address will not be functional.
IPv4 Network Mode: Displays An indication of whether the IPv4 interface is being configured for as DHCP or Static. When it is configured for as DHCP, the IP address is dynamically assigned, so you cannot modify the IP address associated with the interface is assigned dynamically and cannot be modified. When it is configured as Static, you must assign a valid IPv4 address for the interface.
Gateway: Displays the The gateway used for the interface. Each IPv4 gateway supports up to two network interfaces. If you configure more than two network interfaces for the same gateway, the gateway address will not be displayed for those interfacesthem.
IPv4 CIDR: The IPv4 address and netmask.
IPv4 Metric: A metric is a value that you assign to an IP route for a particular interface, for routing purposes. Valid IPv4 metric values are from 0 (default) to 4294967294. The default value is 0. The
BloxOne uses the metric value

to determine which interface

is to be used for cloud

communications. The metric value is important if you have multiple network interfaces configured with the gateway. The lower the metric value, the higher the priority the interface has in the IP routing table. For example, when you set the metric value
...
to 0 for one interface and 20 for another, the interface with the metric value 0
...
will have a higher priority
...
and
...
will become the primary interface to be used for cloud traffic that goes through the configured gateway. If the primary interface

is down, the traffic will go through the next prioritized interface. If you configure the same metric value for two interfaces, the system will decide and take the best route
...
(the one with
...
fewest hops) to the destination via the associated interface. If the number of hops is the same for both paths, the traffic will be load-balanced between the two associated interfaces.
IPv6 MTU: Enter the The maximum transmission unit for the IPv6 network, which is the size of the largest protocol data unit that can be communicated in a single network-layer transaction. Valid values are Enter a value from 1280 to 9001 . The default value is 1500. This value must be and greater than or equal to the IPv4 MTU. The default value is 1500.
If you are
...
configuring a dual-stack network for the host, you must set the minimum MTU value for the IPv4 address
...
to 1280
...
; if you do not, the IPv6 address will not be functional. In addition, the IPv6 MTU must be greater than or equal to the IPv4 MTU.
IPV6 Network Mode: If configured, displays whether the IPv6 interface is being configured as DHCP, RA, Auto Select, or Static.
DHCP: When configured for DHCP, the The IP address is dynamically assigned by the DHCP server, so you cannot modify the IP address associated with the interface.
RA: When configured as (router advertisements, the ): The host in your IPv6 network auto-generated generates a link-local address to communicate with other hosts or neighbors on the same network.
Auto Select: When configured as Auto Select, the system selected The system selects the best way to obtain an IPv6 address for the host.
Static: When configured as Static, you have manually assigned You have to manually assign a valid IPv6 address, CIDR, and a gateway for the host.
Gateway: The default gateway used for the IPv6 interface.
IPv6 CIDR: The IPv6 address and CIDR associated with the interface.
IPv6 Metric: A metric is a value that you assign to an IP route for a particular interface, for routing purposes. Valid metric values are from 0 to 4294967294. The , and the default value is 1024.
The metric value is used by BloxOne to determine which interface should be used for cloud communication. The metric value is important if you have multiple network interfaces configured with a gateway. The lower the metric value, the higher the priority the interface has in the IP routing table.

Interface State: Indicates : An indication of whether the admin state of the configured network interface is administratively Enabled or Disabledhas been enabled or disabled administratively. All network interfaces , except other than the one with the lowest metric value , are Disabled by defaultare disabled by default; a disabled network interface will not be in use, but the configuration will stay intact. To use a specific interface, you must first toggle the state to Enabled (green). When the network interface is disabled, it will not be in use, but the configuration stays intact.

Enable Service Traffic: Displays An indication of whether the BloxOne service is enabled on all IP interfaces or only on LAN.
On all IP Interfaces: This indicates that BloxOne services for this host are enabled on all IP interfaces for this host.
LAN: This indicates that the BloxOne services for this host are enabled only on LAN for this host..
