3097.1Disable heartbeat=SQELEMAN::PAIVAHawkeye - Network Support @GEOFri Dec 29 1995 11:279
    I'd say NO because you'll be in an IEEE 802.3 Ethernet network and not
    an Ethernet V2 one. However, if you have a VMS system for instance
    you'll should see your "Carrier Detect Check Failure" counter increment
    whenever you send a packet (in the DECnet IV line counters).
    
    Cheers,

3097.2Turn it ON.MSDOA::REEDJohn Reed @CBO = Network ServicesFri Dec 29 1995 23:5711
    Heartbeat should ALWAYS be enabled, regardless of IEEE 802.3, or
    ENET_II.  The ONLY time to disable heartbeat is if the NIC side of the
    transceiver is connected to a repeater port, or a DELNI  (The DELNI
    only because someone MIGHT attach a repeater to the DELNI).
    
    Both instances in your example (#1, and #2) are showing the MAU
    connected to the AUI port of a bridge.  In both of these cases there is
    no question.  The SQE should be enabled.
