Re: auto-negotiate not reliable
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
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.

RE: auto-negotiate not reliable
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. -Original Message- From: Healis, Jim [mailto:[EMAIL PROTECTED]] Sent: Monday, September 11, 2000 12:54 PM To: 'Doug Laing'; [EMAIL PROTECTED] Subject: RE: auto-negotiate not reliable I have seen problems like this with certain NIC cards, in particular my experience has been poor with 3Com PC Cards.

RE: auto-negotiate not reliable
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
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 Deepak Doug Laing wrote: Can someone explain to me why auto-negotiate on a Catalyst 5500 and a NIC is not always reliable. **NOTE: New CCNA/CCDA List has been formed.
