I have seen problems like this with certain NIC cards, in particular my
experience has been poor with 3Com PC Cards.  Also, auto-negotiation seems
to be problematic between Sun machines and Cisco equipment.  The best I can
tell is when both sides are set to "auto" they never are able to decide on
one setting or the other and eventually fail due to the numerous errors on
the interface that accrue while trying to negotiate.
I have always played with the settings on the switch port until I see no
errors.

Re: auto-negotiate not reliable

2000-09-11 Thread Dale Holmes

Different vendors implement auto-negotiate in different ways, and sometimes 
those ways are at odds... There is no way to tell whether the firmware in a 
given vendor's NIC is going to respond and react as Cisco expects it too in 
an autonegotiation process. As a general rule of thumb, regardless of 
vendor, when it really matters - explicitly set it... don't do 
auto-negotiation.

RE: auto-negotiate not reliable

2000-09-11 Thread Roan, Wayne

That is correct.  The cards and the switch will continue to "negotiate" for
every tranmission.  You need to change one of them to a certain speed.  They
are both trying to figure out which speed to run at.  If you make one run at
a certain speed, this problem will go away.  I always set the NIC to a
certain speed 10 or 100.

As far as I'm aware - auto-sense is not a "standard", there sren't defined
specifcations for each vendor to follow.

Re: auto-negotiate not reliable

2000-09-11 Thread Deepak Sharma

auto-negotiate is usually a no no.  Reasone being that switches and nics
are usally made by diff. vendors and react differently to each other..

hecki have 3com switches AND 3 com nic cardsand i still need to go
around the office in the morningand do a "winipcfg".lol
