Ethernet settings

The next section is the setup of the Ethernet interface.

ℹ Note
The Ethernet settings and profiles are only valid and processed by the device if the
ETH-WiFi Brigde is disabled .


Enable or disable the ethernet interface

Options: ON/OFF

Default: ON

Ethernet Settings - Connection Profile

Similar as to the regular settings, it is possible to create multiple profiles for ethernet connections. It is HIGHLY recommended to only use ONE Ethernet interface profile as deep network technology knowledge is required to configure multiple profiles.


Connection name

Default: Wired connection

Description: Give the ethernet connection a unique name.

Connect automatically when resources available

Default: ON

Description: Connect this profile automatically when the resources for this connection become available. When disabled the profile will be parked in the configuration, but not actively used.

Auto-connect priority

Type: int32

Default: 0

Description: Priority for profiles that are configured to auto connect, this setting spans over all profiles of all interfaces where the auto-connect setting is set to true. A higher number means higher priority.

The number of times to auto-connect

Type: int32

Default: -1

Description: Number of times to retry to connect the profile automatically before giving up. When autoconnection fails after the given number of retries, the next highest priority profile will be used. A value of zero means retry forever.

IPv4 address of DNS server(s)

Type: string

Default: <empty>

Description: It is possible to setup three additional DNS servers if required.

IPv4 Address

IP address used for either static IP, when method is set to manual or DHCP server configurations when the shared method is selected. The CIRD notation is used to define the subnet mask.

Info
By using e.g.
192.168.82.1/24 the device will be part of the 192.168.82.0 network and will allow access or communication from IPs in the range of 192.168.82.1 - 192.168.82.254
Important
As security measure it is advisable to tighten the allowed IPs on the network as possible, for instance to use
/29 or 255.255.255.248 subnet to only allow (only) 6 address on the network, with 192.168.82.0 is the network address and 192.168.82.7 is the broadcast address and 192.168.82.1 - 192.168.82.6 remains available.

IP configuration method

Available options:

  • auto the interface will be configured as DHCP client and therefore will be assigned a IP address from an external DHCP router.
  • manual , or also called static IP mode. In manual mode, the IPV4 Address defines the network and mask, the device IP is set through IPV4 Gateway , which is described below.
  • link-local , a link-local address is a network address that is valid only for communications on a local link, i.e. within a subnetwork that a host is connected to. The device will auto-negotiate a IP address in the 169.254.0.0/16 network.
  • shared , in the shared mode the device is setup as DHCP Server.

    In this mode, the Network Manager will configure the DHCP server to provide a static IP range for static IPs which is 10% of the range with a max of 8 IPs. The remaining IP in the range are for dynamic assignment.

Default: link-local

Description: IP configuration method, by default the interface is set to use link-local, i.e. auto-ip configuration which makes sure that the device does not disrupt an existing network when plugged in.

The gateway associated with this configuration

Type: string in DNN format.

Default: <empty>

Description: Gateway IP address, usually only needs to be set when manual , i.e. static-ip network configuration method was selected. Keep in mind this should be in the given subnet range.

Routing metric used to make a routing decision

Type: int32

Default: -1

Description: Routing metric, lower values have higher priority. Set to -1 for automatic assignment based on interface type. This option will allow you to prioritize one interface over the other when accessing the internet, depending on interface or connection availability.

First IPv4 address in DHCP range

This option is only available if the IP configuration method is set to shared .

Type: string

Default: <configured automatically>

Description: First IP address of the DHCP range, which the DHCP server will hand-out in a lease.

Last IPv4 address in DHCP range

This option is only available if the IP configuration method is set to shared .

Type: string

Default: <configured automatically>

Description: Last IP address of the DHCP range, which the DHCP server will hand-out in a lease.
