• AIX networking basics: lsdev -Cc adapter, en/et interfaces, smitty tcpip, and netsvc.conf

  AIX exposes each Ethernet adapter as two possible interface types (en for standard Ethernet, et for IEEE 802.3), configures TCP/IP mainly through smitty tcpip / mktcpip rather than a single flat file, and controls name-resolution order with /etc/netsvc.conf or the NSORDER variable; an address set only with ifconfig does not survive a reboot.
