Sorry, I thought we were talking about HiperSockets. Let's use "device" or "subchannel" to talk about the addresses defined in IOCP/HCD. Leave the word "interface" to apply to a TCP/IP link (3 devices/subchannels/addresses). 240 is indeed the OSD chpid device limit on z800/z900. (Increased to 480 on z890/z990.) That yields a maximum of 80 IP interfaces. If you've defined an OSAD, then that reduces you to 79 IP interfaces. > So, I don't know where the 127 device limit comes from. An MVS thing, I guess. I try not to ask "Why?"
