Communications to the HMC, Communications to NTP Servers if you use NTP for your time source for Server Time Protocol(STP). A couple of uses that you would need connectivity from the SE Laptops for.

There are two NIC's in the HMC, and there are two NIC's in each service element. What we did is let IBM install their own private network with switch between the HMC, and SE's on their own private IP's. Then we also cabled up the alternate NIC's in all to our internal network for Web access to the HMC. The reason we cabled up our SE's to the internal network was because we intend on using the PROCOPS function of SA390 to control Hardware based functions at some point. It is all IP based traffic. _________________________________________________________________ Dave Jousma Assistant Vice President, Mainframe Services [email protected] 1830 East Paris, Grand Rapids, MI 49546 MD RSCB1G p 616.653.8429 f 616.653.8497 -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Staller, Allan Sent: Thursday, March 05, 2009 11:00 AM To: [email protected] Subject: Re: z/10 HMC/SE LAN IIRC, the z10 HMCs no longer support token ring. 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> This e-mail transmission contains information that is confidential and may be privileged.
