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.

> According to the manuals we are following ...

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:
