Thanks David. I thought I saw this working sometime before and the previous
response from Lea says it works for him, so are you saying this will not
work?
That could be a problem because we are trying to run RDS(Resource
Dependency Service) which uses NMAP from the mainframe.

Nmap relies on packets that require layer 2 responses. Unless you
explicitly have set up TYPE ETHERNET guest LANs or are using layer 2
VSWITCH, you won't ever get any responses, because the OSA ucode
intercepts them, so nmap decides things are down.
Wrt to arp, yes, that's normal. The layer 3 OSA code is intercepting ARP
before you see it, so the host has no arp cache. Saves a few cycles in
that your guest doesn't have to respond to every ARP request, but
confuses the heck out of normal network tools.
