Hi, I have been experimenting with setting up OSA-ICC cards on a z114. These are OSA Express3 cards with 4 ports / 2 channels. Let's look at a single channel in this card, named CHPID 200.
These are the configuration parameters for this card: > Channel ID: 0200 > LAN port type: OSA-ICC 3270 > > Physical Port 0 > Server name: [empty] > Host IP address: 10.0.0.10 > TCP port (1-65535): 23 > Subnet mask: 255.255.255.0 > MTU size(B): 1492 > > Physical Port 1 > Server name: [empty] > Host IP address: 10.0.1.10 > TCP port (1-65535): 3270 > Subnet mask: 255.255.255.0 > MTU size(B): 1492 > > Default gateway: 10.0.0.1 My most pressing confusion is related to the IP. A configuration with the two ports in the same subnet is considered invalid, yet there is only a single channel-level gateway that seems to be definable. If I try to assign e.g. 10.0.0.10 and 10.0.0.20 with default gateway 10.0.0.1 I get the following error: > // @@@ Error 1057: Host IP for Physical Port 0 and Physical Port 1 are defined in the same segment If I can only define a single channel-level gateway, and the ports cannot be in the same L2, how is this second port intended to be used? One port routable and one port accessible only from the same L2? My second question is if there is any way around the TCP port number not being able to be reused. I would love all my OSA-ICC to use TCP port 23, but it seems that even though the ports need separate IP addresses, the TCP port cannot be the same between the two ports. Is that correct? The error I get when I try to re-use the same port is: > // @@@ Error 1055: Host port value used for previous physical port definition: 23 for PORT 0. Thanks for any insights / experiences. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
