My CE told me that the z/890 used NETBIOS over Ethernet. TCP/IP was used only to verify connectivity with PING.

I thought they were TCP/IP only. Not sure if that came in w/the z/9 or the z/10. HTH, <snip> Any idea what protocol is used on the z/10 HMC / SE LAN? My CE wasn't sure, but he was thinking it was -not- TCP/IP. My network folks want to replace the IBM supplied Ethernet switch with a firewall/router appliance. The business need is to access the web server on the HMC for remote operation, and the way we did that on the outgoing machine was to just tap into that LAN. I'd prefer we kept out of that LAN and use the second NIC on the HMC. </snip> ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
