Hi,
 
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 located.
 
------+-----------+--------+--------
       |            |         |
   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 product?
 
Thanks,
 
Matt
