In a typical setup, the IEM and cloud access are reachable via default route and default gateway. In this case, enable the `Gateway Interface` check box for the network interface, for example either X1 or X2, to which the default router and the default gateway is connected to.
If this default network interface is not reachable or the connection to the interface fails, a connection to another network interface is attempted to be established.
MAC Address
Depending on the Edge Device Type, either `MAC Address`, `Ethernet Label` or both is available.
If the Edge Device Type requires a MAC address, this field is enabled.
In case both `MAC Address` and `Ethernet Label` are available, select 1 of them you want to use.
Enter the MAC address of the network interface which is currently configured.
Use colons as separations.
Example MAC address: 00:0c:29:82:3f:81
Ethernet Label
Depending on the Edge Device Type, either `MAC Address`, `Ethernet Label` or both is available.
If the Edge Device Type requires an Ethernet label, this field is enabled.
In case both `MAC Address` and `Ethernet Label` are available, select 1 of them you want to use.
Select the network interface you want to use to connect the Edge Device to the IEM.
DHCP
Enable or disable IP address assignment through DHCP.
If this check box is selected, the IP address is assigned through DHCP.
When the check box is disabled, static IP address assignment is used.
IPv4
Only enabled when DHCP is disabled.
IP address of the Edge Device in the network.
Input of the IP address is mandatory when DHCP is disabled.
Netmask
Only enabled when DHCP is disabled.
Subnet mask in the `255 255 0 0` format, for example.
Input of the subnet mask is mandatory when DHCP is disabled.
Gateway
Only enabled when DHCP is disabled.
IP address of the gateway.
Input of the IP address is mandatory when DHCP is disabled.
Primary DNS
Primary DNS server address.
Input of the DNS server address is optional.
Secondary DNS
Secondary DNS server address.
Input of the DNS server address is optional.
Start IP Address
L2 network access is optional.
Start of the L2 network access IP address range.
Number in the last octet must be even.
Input of Start IP Address is mandatory for L2 network access usage.
Netmask
Netmask defines the section in which the IP addresses are located.
Input of netmask is mandatory for L2 network access usage.
IP Address Range
Length of the IP address range for usage of Edge Apps with direct L2 network access.
Minimum IP address range is 2, maximum range is 256.
Valid displayed IP address range depends on last number in Start IP address, for example:
If last number of Start IP address is 16: 1, 2, 4, 8 and 16 is available.
If last number Start IP address is 172: 1, 2 and 4 is available.
If last number Start IP address is 0: 1, 2, 4, 8, 16, 32, 64, 128 and 256 is available.
Input of IP address range is mandatory for L2 network access usage.
NOTICE
MAC address and Ethernet label
It depends on the Edge Device Type which input type is required for the network interface settings, whether MAC address or Ethernet label.
The Edge Device builder by himself forces which type is required and must be provided to onboard the Edge Device to the IEM.
The parameters in the Layer 2 for Apps (L2) section and thus the configured Layer 2 network access is independent of the DHCP and Gateway Interface configuration.
Ensure that the Edge Device IP addresses and the configured L2 network access configurations do not collide with addresses of other devices in the network.
NOTICE
IP address and broadcast IP address of subnet
Do not use the IP address and the broadcast IP address of the subnet defined by the netmask for the configured IP address range.
For more information regarding the configuration of Docker IP address ranges, check the official Docker documentation.
