1399.0. "Qustions re DEFTA" by WELCLU::ZELEZINSKI () Wed Jul 13 1994 10:04

    I am looking for help with a couple of questions raised by a customer
    who is building a Network Control Station based on an Alpha 3000/600S
    with multiple network connections including FDDI. This system will need
    to monitor all Network traffic therefore "promiscuous mode" on the FDDI
    is required. Is this supported on the DEFTA with OVMS and how is it set
    up ??
    The system also has to monitor VME based FDDI cards and for some reason
    the customer needs to know what ver of MAC we support and if possible
    what chip set we use, is it proprietry or from AMD ???
    Finally if using TCP/IP they achieve thru puts of 50Mbs will the Alpha
    processor be able to handle this amount of data as well as doing other 
    tasks ???

Yes.  The LAN chapter in the I/O User's Guide describes how to turn on 
promiscuous mode for a device using QIO.

All our adapters support promiscuous mode (as do all the Ethernet
adapters).

Alphas should have no trouble at all keeping up with 50 Mb TCP traffic.

Our adapters use our own MAC design, which is also the one sold by
Motorola.  Not that it makes any difference; they should all conform
to the FDDI standard...
