(12.4.1-en) LAN Interfaces in IGEL OS 12

You can use the LAN tray app for quick ethernet network configurations. For details, see (12.4.1-en) Tray Applications in IGEL OS 12.

Predictable Network Interface Names (PNINs)

The names of Ethernet and WLAN interfaces are predictable network interface names (PNINs), see Predictable Network Interface Names. This ensures the stability of interface names on reboot and generally improves the reliability of associating configurations with interfaces.

• As "eth0", "eth1", and "wlan0" have been replaced by PNINs, configurations or custom scripts that include the old names of Ethernet and WLAN interfaces, e.g. eth0, eth2, wlan0, have to be adjusted. 
  The following already existing configurations do NOT require manual adjustment since old names eth0, eth1, etc. will internally be replaced by the correct PNINs automatically:

• To view the PNINs and the order of the configured interfaces, you can use the following commands. The default interface is always listed first, the second interface is listed second, etc.
  Ethernet (LAN): cat /config/net/en-interfaces
  WLAN: cat /config/net/wl-interfaces
  (Note: Only the first wireless interface (former wlan0) is supported. All other wireless interfaces will be ignored.)

• If you need to configure more than two Ethernet interfaces, go to System > Registry > network.interfaces.ethernet.device% and add an instance by clicking Add Instance.
  To explicitly assign a configuration instance to a certain interface, enter the corresponding PNIN for the registry key network.interfaces.ethernet.device%.ifname.
