mediaopt full-duplex DOES NOT work..
Folks, you have been able to issue the command to force duplex since 10.0, problem is, it doesn't do anything.

I found this problem as well. It appears that you have to supply both link speed and duplex for it to take in OSX 10.2. I ran the following first:

I would also like to make these settings -- did this work for you?

I checked system.log in the Console and it reports that my ethernet is indeed still only running at half-duplex. :( Well the lesson here is: just because you don't get an error message anymore don't assume it's working.

Indeed there are many cards that don't honor user settings, including systems such as AIX and their implementation of Token-Ring adapters.

File sharing I can understand, but I'm not sure about the gripe about network performance. I routinely saturate 100baseT ethernet from my laptop (PBG3 Firewire -- Pismo). It keeps pace just fine with AIX systems at work, and AIX has a _very_ good network stack.
I see no particular problems with Jaguar, at least on my hardware, with either network throughput or latency. I do agree that, e.g., ifconfig should actually do what it's told to do, but I don't see performance issues.

I have just gone through the same problem with our network of Mac's and PC's.
We have both Cisco Catalyst 35xx-XL's and 29xx-XL's in our network that are interconnected using Gigabit Fibre. You need to stop the spanning tree protocol at port startup in these switches for the Mac's to autonegotiate the link correctly.
To do this either use the Cisco Cluster Management Suite (CMS) to turn ON PortFast and set Duplex and Speed to Auto, or add the following to your ports config using telnet:
interface FastEthernet0/4 %% Your interface here description MacTest %% port name switchport access vlan 4 %% vlan its in spanning-tree portfast %% This is the only nonstandard option ! %% and stops STP from delaying port/link startupThis has fixed most of our network issues with Mac's and all the NIC's report the correct duplex and speed at both the switch and the machine. Hope this helps.

I got this to work on an XServe and a G-4, but not on my G-3. You have to have the media option and the mediaopt option in the command or it will not do anything. For example: |
