The IP INTERFACE SETTINGS page displays the following information for a specific host:

NETWORK INTERFACES

  • Network Interface: The names (such as enp1s0 and enp2s0) of the Ethernet ports on the appliance. All network interfaces you have configured appear in the table. You cannot modify this field.

  • Interface Label: The interface label defines the interface binding between the BloxOne service and the interface on which the service runs. This can also be the custom label you use to associate the host with the interface binding.

  • IPv4 Network Mode: An indication of whether the IPv4 interface is configured as DHCP or Static. When it is configured as DHCP, 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.

  • IPv4 CIDR: The IPv4 address and netmask of the IP interface. You can modify this field, if necessary.

  • IPv4 MTU: 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. 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.

  • Gateway: 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 them.

  • IPV6 Network Mode:

    • DHCP: The IP address is dynamically assigned by the DHCP server, so you cannot modify the IP address associated with the interface.

    • RA (router advertisements): The host in your IPv6 network auto-generates a link-local address to communicate with other hosts or neighbors on the same network.

    • Auto Select: The system selects the best way to obtain an IPv6 address for the host.

    • Static: You have to manually assign a valid IPv6 address, CIDR, and a gateway for the host.

  • IPv6 CIDR: The IPv6 address and CIDR associated with the interface.

  • Gateway: The default gateway used for the IPv6 interface.

Interface State: An indication of whether the admin state of the configured network interface has been enabled or disabled administratively. All network interfaces other than the one with the lowest metric value are disabled by default; a disabled network interface will not be in use, but the configuration will stay intact. To use a specific interface, toggle the state to Enabled (green).

VLAN INTERFACES

If you have configured virtual interfaces, the following is displayed for each virtual network:

  • Interface: The names (such as enp1s0 and enp2s0) of the Ethernet ports on the appliance. All virtual interfaces you have configured appear in the table. You cannot modify this field.

  • VLAN ID: The VLAN ID of the respective VLAN interface.

  • Interface Label: The interface label defines the interface binding between the BloxOne service and the interface on which the service runs. This can also be the custom label you use to associate the host with the interface binding.

  • VRF: The virtual routing and forwarding networks.

  • No labels
