    No.  Neither our SAS or DAS adapters support dual-MACs.  In fact, I
    don't know of any Digital FDDI products that support this "feature".
    It's certainly NOT an ANSI specification that dual-attach adapters
    support dual-MAC's...or we'd be out of compliance for many years now.

| 1485.2 | Got it! | JAHMAN::ELLIS | Peter S. Ellis Jr. - MBAd (More & Better Ads!) | Tue Oct 25 1994 12:13 | 4 | 
|  |     Thanks for that prompt answer, man.  My customer was trying to figure
    out how he could use a pair of DAS connections between GIGAswitches
    with both links active, and this came up during the discussion.
    pellis.

    I'm not that familiar with all of the connection possibilities of the
    GIGAswitch, but if the DAS connections are on the dual-ring, then both
    PHYs are active.  If you're dual-homing, only one is active (B) and the
    other is standby (A).  Neither option is predicated on having
    dual-MACs.  By the way, you may want to search for dual-MAC topics in
    this Notes conference.  I'm sure this topic has come up before.

|  |     Thanks, Larry; I'll do just that. While I'm at it, I'll post an entry
    in SCHOOL::GIGAswitch, as well.
    
    pellis.

|  |         ...in this notes conference, see notes 239.*, 288.*, 766.*, 818.*
    for additional discussion on 2 MACs and related concepts.
    
        The GIGAswitch/FDDI is just like our other devices.  With FGL-2
    cards, the GIGAswitch/FDDI can provide A/B/M/S ports.  With FGL-4
    cards, the GIGAswitch/FDDI currently provides S port support, but will
    soon also provide M port support.  None of them provide 2 MACs.
    
        I'm not quite sure what your customer is trying to achieve, but
    note that the GIGAswitch/FDDI provides M port support, which allows
    systems with DAS interfaces to dual home the interface to two different
    ports (on different devices, if desired).  Dual homing has nothing to
    do with 2 MACs, though...
