> Let me state up front I know sod all about TCPIP ... 1. Consult the minimally one person in your "shop" who has been educated in matters to do with the Internet Protocol (IP) and its related protocols such as TCP and see what he or she thinks about your configuration definitions. 2. Perhaps both of you could consult the following redpaper which I found excellent on its first topic VLANs and appears to be as excellent on the topic of VSWITCH.[1] Linux on IBM eServer zSeries and S/390: VSWITCH and VLAN Features of z/VM 4.4 http://www.redbooks.ibm.com/abstracts/redp3719.html 3. Such questions as this are best posed in list IBMTCP-L where there is the greater concentration of expertise in the products of which the first manifestation was the first version of "TCP/IP for VM" back in the early '90s. Having said that, many of the denizens of that list also keep an eye on IBM-MAIN.

Posters should always state precisely *which* manuals they are following for very obvious reasons one of which is to avoid responders mentioning what is already known! - [1] However I need to qualify this by saying that "VM guru" Alan Altmark has been less keen on this redpaper saying that the latest edition of the manual "(z/VM) Connectivity" should be used for everything to do with VSWITCH. The latest I can easily locate is the following: http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/HCSC9C00/ - Chris Mason On Wed, 20 Jun 2012 04:53:19 -0500, Ron MacRae <[email protected]> wrote: >Hi all, > I have a VM & zLinux vswitch issue that I'm hoping someone can help me > with.
