A customer of mine was advised by another supplier to locally
adminstor the allocation of MAC addresses for new PCs being connected
to workgroup 10BaseT hubs for access to NetWare only.

I've stongly advised aginst this with arguments for being:

o	Original MAC addresses ensure uniqueness
o	Network Management s/w such as NMS can easily identify and
report
	MAC addresess in use/user connected, etc.

The only time I've seen MAC addresses being locally assigned (to
over-ride the manufacturer's address) has been in IBM AS/400
environments where the IBM admin specifies on the host which MAC
addresses can access the AS/400.

What are the benefits of this being done and why don't they just use
the originally assigned addresses?

Thanks,
Mike./
