Full duplex Nic settings

Hello,
I use the bootcd.iso, to make an image from a brandnew pc and put it on a
special ZEN server. It works, but it is ****ing slow. We use cisco
switches and have a 100 full duplex network speed in our workstation
settings. So NO autosensing! How (and in which config file) can I change
the settings in the bootcd.iso image so I have a 100 full duplex
connection instead of auto sensing?

I included 'mii-tool' in our images. It's available on a lot of Linux
systems and can be used to view and adjust the settings of the NIC.
Just run 'mii-tool' to view the settings or run
'mii-tool -F 100baseTx-FD'
to set it to 100 Mb Full Duplex.
HTH.

B200M3 and Vsphere 5.1 - Unable to set NIC speed to 10gb full duplex

Hi,
My first post here!
I got 4 B200M3 blades with VIC 1240 and 1280. I have installed vSphere 5.1 on them. The blades are configed with a number of NIC's.
The NIC's get a speed of 20gb full duplex(set on auto negotiation) and i would like to set them to 10gb full duplex. When i try to change it in vSphere i get an error message
"Call "HostNetworkSystem.UpdatePhysicalNicLinkSpeed" for object "networkSystem-1264" on vCenter Server "xxxxxxxxxxxxxx" failed.
Operation failed, diagnostics report: Forcing 1000Mbps or faster may not be supported on this network device, please use auto-negotiation instead"
After some searching it looks like you sometimes have to upgrade vSphere with new drivers to get these things to work?
Anyone got any ideas that can help me?
// Fredrik

Hi Fredrik,
A few quick questions:
1) What is the driver type and the version on the vnics? here is the HCL for the required driver versions:
http://www.cisco.com/en/US/docs/unified_computing/ucs/interoperability/matrix/r_hcl_B_rel2.04.pdf
2) Did you install 5.1 direct or did you upgrade from 5.0? For this blade you need to use the CISCO OEM Custom ESXi image. We still do not have the 5.1 image published, however the 5.0 and 5.0 U1 are avaiable for use. Here is the download location:

Mac Pro 10.6.5 100baseTX Full Duplex Not Working

Hi Guys,
I am having some trouble with the Mac Pros that I support in my office (Early 2009 Model). Our network uses 100baseTX Full Duplex on all of our connections in a mixed PC/Mac environment. This was working perfectly fine until we updated our Mac Pros to 10.6.5 (Went straight from 10.5.6 to 10.6.5).
Every Mac Pro now has itself set to automatically detect the speed, and they keep setting themselves to 100/Half. If I go in and manually adjust it, setting it to 100/Full, I lose all connectivity to the ethernet (it doesn't even recognize that a cable is plugged in). This is causing a lot of troubles for our Mac users trying to access files on our shared drives. It is taking them about 5 minutes to download a 30MB file, rather than the 3 seconds it should.
I tried booting to our portable 10.5.6 drive and 100/Full works just fine. Our PowerMacs on 10.4.11 also work fine on 100/full. I tried using Cocktail and Sudo to force the change, but again the ethernet drops out. The problem persists through all user accounts on all the effected Macs. I have tried a fresh install of 10.6 and the problem persists. If I downgrade back to 10.5 the problem is gone. I know it is not an issue with the network because 2000 other machines are working just fine, and the affected ones work fine when downgraded.
I just spent a good hour on the phone with AppleCare, but after insisting it was a problem with our network for the first 45 minutes, they came to the conclusion that they simply could not help me. According to them, if I want networking help, I need to convince my company to spend $2,800 on their enterprise support, and even then they don't know if they will be able to help me. So, it looks like I am on my own here.
Anyone have any thoughts on what is going on or how to fix it?

The only possibility that I can see is that it is a software problem on these Macs.
There is always a certain level of slack engineering into all these devices. When you start updating one part of a network, you risk exceeding the slack. It is always possible that the problem is with the router hardware or cabling. Certainly, the problem would be with 10.6.5 too. But if you jump to one conclusion or the other without troubleshooting you risk waiting forever for a fix that will never come.
So, what you have to do is connect these Macs to some other router/hub running 100BT/Full (with settings as close to default as possible) with cables that you know are rated at that speed. If that fails, submit a bug report to Apple. If it works, take your router/hub and put it in the network cabinet and connect it to the Mac Pro with the existing cable. If that fails, sue whomever installed the cable and redo it (network people sometimes try to save money with cable). If that works, look at the existing router/hub and see if it has any bugs or firmware updates available. At this point, you could submit a bug to Apple with precise details about your router/hub and also submit one to the manufacturer of the router/hub. Apple will either fix the problem or contact the router/hub manufacturer and get a fix. Once you know precisely what connection is causing the problem, there may be other ways to address it either on the router/hub side or on the Mac side.

3Com elxl in Solaris 10: Force full duplex?

After being up for a few hours, my Solaris 10 (11/06 release, patched up to date), appears to virtually stop functioning network-wise; throughput goes to single-digits/second. I'm guessing this is a duplex mis-match, but editing /kernel/drv/elxl.conf to force full-duplex kills the NIC altogether, generating a stream of errors.
Searching this forum shows discussions of stuff like this going back to Solaris 8, but most threads are inconclusive.
Anyone have a final conclusion?

But when I want
a static ip by putting the ip in hostname.bcme0 it
gives me this in bootup(pasted only the interesting
bits):As the filename hostname.bcme0 already suggests you don't enter an IP adress there but a hostname. The IP adres is then picked up by checking the hostname against /etc/inet/hosts.
You might want to check out http://docs.sun.com/app/docs/doc/816-4554/816-4554#hic for more information on this matter.

How do I set up the port interface for the WAN side of my RVS4000 to 100T Full Duplex?

How do I set up the port interface for the WAN side of my RVS4000? The ISP says I need to set it to 100T Full Duplex, but where would I do that? In the Router's administration GUI I can't find any options to make such settings for the WAN side.

The setup of the folders in Finder is entirely up to you. Whatever suits your needs is what you should do. Lightroom will be fine no matter how you set it up.
So I'm not really sure what your question is.

10.6 update disables full duplex ethernet

Updated to 10.6 and immediately lost all internet connectivity. Network control panel reported "Cable Unplugged."
Restarted in 10.5.8 -- 100Mb connection worked fine.
Restarted again and back in 10.6, I fiddled with settings and found that by manually switching to "half-duplex" ethernet (under the "advanced" tab) internet connectivity returned. (Connectivity also resumes if I choose the "automatic" configuration, because that too switches over to half-duplex). Either way, the working connection seems a noticeably slower than 10.5.8, which I assume is the difference between half and full duplex.
Any ideas on how to restore the connection to full duplex?

Thanks for the tips
It is looking more and more like a driver issue with the Intel Pro 1000 card that came with the Mac Pro. I've found people with similar loss of full duplex with this card (sometimes unrelated to Snow Leopard).
Intel no longer supports the card or driver apparently, having sold that operation to www.small-tree.com. SmallTree's Web site states that a problem exists with the driver and Snow Leopard and offers a possible work-around at http://www.small-tree.com/gigabit-ethernet-driver-download-a/198.htm.
(The driver must be installed with the current ethernet card removed. Unfortunately, every how-to guide I've seen assumes you're replacing the easy-to-access PCI cards, but the preinstalled Mac Pro card appears to be hidden back behind the main fan and I don't see an easy way to get to it.
Am I missing something obvious?)

WAN Port Full Duplex

I have connected my UC540 latest software pack to a FIOS Box. i'm only getting half the speed.
Can someone post the steps on CLI to make the WAN interface full duplex please?

It would be `interface FastEthernet0/0` for a UC540 actually.
In any case, I believe they are set to "auto" by default... which should have chosen full duplex.
From his description it sounds more likely that he has a throughput problem than a half-duplex issue.
How fast is your FIOS connection? The UC500's aren't really designed for very high speed WANs.
The other thing to check would be traffic shaping settings, if misconfiged, they could certainly limit your speed.

Half to Full Duplex

I am looking at an ASA5510 that is using the management port for several VPN connections. It has connected at 100/HD and I am not sure what will happen if I start trying to force that to full-duplex. Will this take down the port? Will it cause any of the VPN connections to drop? Unfortunately, this is a live box and an outage would not be good.
Any help would be appreciated. Thanks.

Will this take down the port? Will it cause any of the VPN connections to drop?
Changing port transmission settings on any live port either on asa or switch or router will bring down the port for few ms and brought backup quickly..but connections most likely will be dropped and will required to reconnect.
suggestion is to make port changes during non-production hours.

Checksumming/Full Duplex on WUSB-G w/SpeedBoost

Hi. I am using a wireless router for internet, and have recently had problems with the 2.01 patch of World of Warcraft. One of the technical suggestions they recommend is setting Checksum Overload to off, and 100x Full Duplex. I do not have either of those settings on my router.
Furthermore, when I try to login into 192.68.1.1, I am prompted for name and password. I leave name blank and enter "admin" (no quotes) for password, but this is not correct. I have never changed the settings of this router.
I believe it has the latest drivers (not sure of specific #)
If anyone can help me adjust the checksum and full duplex options, I would be grateful.
If it is helpful for resolving the greater WoW problem, I can post the description I left on the WoW tech support forums

Checksum Offloading is a hardware function of some high performance network cards - the card does the calculation and inserts the checksum into the packet. This reduces network overhead (CPU Utilization) on the PC.
The USB device does not have this feature.
You did not say what model router you have, but the manual can be downloaded from the www.linksys.com page under support -> Downloads - you need to select your model.
But the short answer is to press and hold the reset botton for at least 10 seconds. This button is located on the back of the router, next to the Internet connection - it is inside a small hole. You need a small pointed object to press on it (a straitened out paperclip works). Then you will need to reconfigure the router as it will be like it just came out of the box...

Can I force my AE into full duplex mode?

I have a newer (Late 2013) Airport Extreme for my office. My new internet provider is sending me a non-negotiating, full duplex signal. Because the AE want's to negotiate, my speeds are very slow. Is there a way to change my WAN settings to force a full duplex signal?

Older version of Airport Utility (5.6) allowed you to change it. What version of the Airport Utility are you using?
It will appear that you can change the setting using AirPort Utility 5.x......but the change will not "stick" after you try to update the settings on the AirPort. The AirPort will still be set to "Automatic" due to different firmware in the newer AirPort and Time Capsule.
Apple Support confirmed this recently, as did the local Genius Bar, after we tested at the Apple Store.

Full duplex with a 100 FX connection

Hello,
I have a WS-2960-24TC-L running with c2960-lanbase-mz.122-40.SE.bin with two GLC-GE-100FX= in it.
I am trying to link this switch to a 3750 with a GLC-GE-100FX= and a WS-2955C-12.
The 2960 always auto negotiate to 100 half with both switches. In the 3750 I can force the port to Full duplex but the DUPLEX command in not ava lable on gig 0/1-2.
I would be nice to have a 100 Full link between the switches.
Can you help me ?

Current GigE is full-duplex only.
You might try using a 10/100 port (as a trunk port if necessary).
You can also try another cable, preferably a commercially made cable in good condition. Poorly terminated hand-made cables, or cables that have been kinked, stretched, crushed {etc} can cause the ports to downshift.
Good Luck

Ettus USRP B200 full duplex at 16 or 32 MSPS?

I am testing the B200 with two different PCs, both running Ubuntu 14.04 LTS.
One is a 4 year old Core i7 PC with an Intel MB and a NEC Corporation uPD720200 USB 3.0 controller.
The other is a 1 year old Asus G750 laptop with an Intel 8 Series/C220 USB 3.0 controller.
Both machines can handle sustained (a few hours) 350+ MB/second transfers from a Point Grey USB 3.0 camera over a 3 meter cable with zero USB 3.0 errors reported by Point Grey's software. Note this is one direction of data flow over USB 3.0, not full duplex. The PC reached 356 MB/second. The laptop reached 369 MB/second. Both error free over periods of about 1 hour.
The B200 can reliably TX and RX (full duplex) at a common data rate of 4 MSPS on both machines.
8 MSPS full duplex is intermittently OK (occasional buffer overruns on both machines). Note: (8 MSPS) * (2 bytes/sample) * 2 (RX + TX) * 2 (I + Q) = 64 MB/second... fairly low for what USB 3.0 is capable of.
16 and 32 MSPS full duplex is never reliable (all runs result in buffer overruns and missing RX or TX data).
Command I'm using (set for 8 MSPS):
nice -20 ./txrx_loopback_to_file --file samples.dat --type float
--nsamps 50000000 --tx-rate 8000000 --rx-rate 8000000 --tx-freq
915000000.000000 --rx-freq 916000000.000000 --tx-gain 0.000000
--rx-gain 0.000000 --wave-type RAMP --wave-freq 10000.000000
Note this is 1 channel TX + 1 channel RX full duplex. Wire format is "sc16" (16 bits per sample over the bus I believe). Data format is "fc32" (32 bit float). I've tried both the stable and unstable UHD drivers.
I also observed that a moderate bend of the USB 3.0 cable will noticeably reduce reliability. Nothing too severe as to permanently deform or damage the cable.
I suspect RFI is affecting the USB 3.0 signals.
*** Questions ***
Any suggestions on how to achieve reliable 16 or 32 MSPS full duplex transfers? Hopefully reliable as in sustained full-duplex TX and RX or an average of 15 minutes between data transfer errors.
Has anyone placed their USRP B200 or B210 in a metal enclosure? Was reliabliity affected?
Has anyone tested their B200 / B210 with different USB host controllers and found a controller that is ideal for full-duplex TX+RX at the 16 or 32 MSPS rates?
Do full duplex TX+RX configurations create a significantly greater I/O challenge over USB versus TX-only or RX-only?
Or is the USRP B200 / B210 simply not the best hardware for doing sustained 16 or 32 MSPS full duplex TX and RX? Better to use a PCI Express interface SDR?

John,
Thank you for your time and help.
Yes I have posted to the USRP-users mailing list along with more detailed test results. I've also corresponded with Matt Ettus.
Thank you for the link to benchmarks. I later found that. I have stopped using the B200 with the computer with the NEC controller although it did give similar results versus the laptop with the 8 Series/C220. I am now just testing with the Asus Laptop with the 8 Series/C220 controller.
I do appreciate that the PCIe or 10-gigabit based SDRs are more reliable. Matt told me this too. I would expect this based on the prices. I am more concerned that full duplex with the B200 appears almost useless. Maybe my 8 Series/C220 controller has electrical or RFI problems? Maybe my B200 is defective?
I am concerned with the $5000 cost for a PCIe or 10-gigabit Ethernet solution when a PCIe x4 capable FPGA now only cost $100 or $200 more than the FPGA and Cypress FX3 that the B200 uses.
I'm tempted to instead spend $5K to roll my own PCIe MIMO SDR for $750 to $1000 per board versus spending $5000 for one X300, RF daugtherboard and external PCIe kit. And I can customize it to my needs better. Per Vices did exactly this and offered a $750 (later revised to $2500) PCIe SDR board with 100 MHz simultaneous TX and RX bandwidth.

HP Color LaserJet CM2320fxi MFP - Full Duplex Problem

Hello!
I've got LaserJet CM232 and Win7 (x64). My problem is that when I'm printing for example 4 pages of a document it's printing only in full duplex, so 2 pages printed on both sides. I can't find where can I fix this duplex problem, I'd like to choose manually if it will be printing in full duplex or not. Help me find a solution, please.
Second problem refers to the time of printing. When I print something I have to wait several minutes to print it. Is that a RAM problem? More RAM memory will resolve this problem?
Thanks a lot for your replies! I'd really appreciate any help!
Best regards,
Kuba

Full Duplex Lost with Wave Files on SB Live! Value (W

Following a clean install upgrade from WinME to WinXP SP2 on a Dell Dimension 400 with an OEM-installed SB Li've! Value (WDM) PCI card onboard, full duplex wave audio (recording one wave file while playing back one or more other wave files) ups and disappears ? ME had it, XP doesn?t. The record side of software mixers I use on the XP OS (Quartz AudioMaster, NCH Swift Sound MixPad/WavePad) fail to acquire or record the wave signal(s) being played back by the mixer side of the application. Stand alone recorders (Roxio Easy Audio Capture, HotKey Sound Recorder) also fail to acquire or record the wave signal(s) being played back by the aforementioned mixers. But if I switch the record input to microphone during the record pass (on those apps that permit such midstream switching), the mic records without incident.
Creative?s Auto Update shows all drivers for the sound card are up to date. Applying Creative?s Knowledge Base Solution ID 645 passes all DXDIAG tests with no problems (text file results available if anyone cares to see them) but the manual test using twin Sound Recorders fails as the second copy (record-designated) Sound Recorder fails to acquire or record a signal from the first copy (playback-designated) Sound Recorder (no error codes display at any time). Clean booting WinXP and running the same record passes doesn?t rectify the problem.
Anyone know what?s going on here? And how to fix it's I?m stumped.
TIA . . .

For benefit of anyone who hits this thread in a search:
FWIW - Following 5-weeks of troubleshooting this problem with Microsoft Tech Support (including a parallel install of the XP SP2 OS), we reached the following conclusion: Since the OEM sound card (Creative Model CT4780) was known to operate in full-duplex mode without incident under my system's prior ME OS but the same card fails to consistently operate in full-duplex mode while running under a virgin parallel install of the XP OS, the source of my full-duplex problem must lie in the files and drivers resident on the XP OS CDROM and dropped to my system by the OS loader/installer. There really isn't any other plausible explanation. Absent its drivers, a sound card's nati've hardware state is either going to be full-duplex or it isn't - it would never be full-duplex sometimes and half-duplex (or simplex) the rest.
The problem was resolved when a retail, nearly identical, sound card (Creative Model SB040) and the drivers and files from its CDROM, were installed on the same system.
Perhaps, somewhere, drivers exist that will permit the CT4780 to operate consistently in full-duplex mode on an XP SP2 OS - but neither Microsoft, nor I, had any success in locating them.
