Help!<br><br>we have one LAN hardware interface. However, the way I understand AIX is it creates two interfaces for this hardware. the en0 and et0 drivers. the en0 driver is used for TCP/IP communications. I've already assigned an IP address to this interface, we have code that creates sockets, and this all seems to work great. Yet, we also need to communicate link level. I know the et0 interface is configured IEEE 802.3 so it should support link level. I thought all we needed to do was open("/dev/et0"...). But there is no et0 device under the /dev directory. So I don't know what I'm doing wrong. Do I need to further config the et0 interface? Any suggestion on how to make our link level work?
