was told the 8992 could not be used because JUMBO packets not support on network.?? so I guess that is a factor..?? \ From: Chris Mason <chrisma...@belgacom.net> To: IBM-MAIN@bama.ua.edu Date: 04/14/2010 08:48 AM Subject: Re: Fw: LINUX on the MAINFRAME Sent by: IBM Mainframe Discussion List <IBM-MAIN@bama.ua.edu> Ron I'll try to get back to you on this - and whatever else you that may be concerning you - when I have a chance. Meantime, in order to discover what MTU size applies to what type of interface, you should use the famous Figure 1, "Summary of DEVICE and LINK statements" in the z/OS Communications Server IP Configuration Reference manual - where, you will discover that the value for IPAQENET with Gigabit Ethernet is 8992.
