Well, you could check out the Nways Manager for AIX web site,
The LAN component of Nways Mgr includes the LNM application. This might be
kind of a big gun for what
you want to do, but it comes with applications to do device-specific
management of of IBM networking hardware,
and since that's what you have, it might be worth checking into. Runs on
top of Netview.

I am wondering if Netview provides a mechanism or add-on to support
MAC-Address based network configuration. For example, the way Netview works
for us now, say we have a Network segment (Net 160), with pc's connected to
it. When a node goes down, we know it is on 160 and where it is physically

       |            |         |
   Net 160    pc      xxx

We are moving to a switched environment, based on MAC-Addressing. So a PC
on Net 160 connects to an 8271 (8271A below) device which in turn is
connected to an 8274 (8274A) device. This 8274 device could be connected to
other 8274's. The pc is part of the virtual network 160 defined in the 8274
device. If we move the pc to another physical location, and connect to a
different 8271(8271B) which connects to a different 8274 (8274B) the pc can
still be part of the vlan 160. If the pc goes down, it will show as such in
the 160 segment, but we will have no way of knowing where that node is
physically connected.

  pc   ===>  8271 device A    --move--     pc  ==>  8271 device B
                        /                      pc              /
                       /                                       /
         8274 device A       connected       8274 device B
              net160          <========>       net160
               netX                                        netX
               netXX                                      netXX

Does Netview provide any support for this? If not, is there an add-on
