[Sunhelp] hme NIC lying?

[Foust, Kal E]

Were you using <ndd> command?  When I queried my environment, I couldn't get
an answer from the switch side.
I'm a long way from expert on this, but I just went through a problem
involving Cisco Switches and the hme cards installed in a e4500.  The "end
game" was that (in our environment) both ends needed to be set to half
duplex for best throughput.  The tip for me was in the SunSolve Infodoc
17416, dated 03/2000 which states:
 "Full Duplex is only supported when connecting two Sun systems back-to-back
using a crossover cable - IEEE Industry standards for Full Duplex
inter-operability between vendors will be completed in the near future."

Personally I found this astonishing, but the setting marriage between
devices solved our network problem.
Anyone that can shed some light on this, PLEASE speak up.

Strange query for all the network experts out there...

... Has anyone come across a case where the hme interface lies about what 
duplex setting it's using?

Reason being is that we've moved one of our interfaces from one hub to
another. 
The new hub
reckons that it's using full duplex, but the interface reckons on only 
half-duplex. And yes, we have tried the
original hub port (reported as full duplex) and other new hub ports (still 
half-duplex).

Any advice welcome...

Bob Cross.
