Mac Pro - Link Aggregation Group

Hi community, 
does any now know in what mode the virtual interface feature LAG (Link Aggregation Group) on a MacPro operates?
The LACP modes are: On / Active / Passive / Off 
And what driver mode is used?
The driver modes are: Round-robin / Active-backup / XOR (balance-xor) / Broadcast / Adaptive transmit load balancing (balance-tlb) / Adaptive load balancing (balance-alb)
There is nothing to ajust.
Kind regards,
Nils

Link Aggregation only works when the device at the other end of the Links understands the commands of Link Aggregation Protocol. These tend to be Industrial-Strength Switches and Routers, not the affordable ones most Homeowners buy.
The constraints of the other device, listed in its manual, will determine the best choices.

    Somehow the Notes app on my personal iPhone 4 has synced with my workplace Mac Pro.  How do I change this?

    They do not have the same apple id's.  I want to sync notes to my personal computer through icloud - just not my work computer. I will try to delete the account for my work Mac the way you suggest.  I just can't figure out how my Mac Pro linked to my personal iPhone.  They are separate accounts, separate ids, separate emails, Mac Pro account was set up by the IT guy at work.  Thanks for your help.

  • Mac Pro 6,1 STILL having issues with Open CL (4K scaling and SpeedGrade direct link grades)

    I've seen the staff responses to the issues of the new Mac Pro GPU saying that 10.9.4 fixes everything. For me, it has fixed my export issues, so I'm glad. I'm no longer getting lines and artifacts on my renders.
    That's great.
    However, I'm still having several issues, and they seem to be linked to Adobe and Open CL.
    Here's a video that shows what's going on:
    mac pro issues july 7 - YouTube
    Issue #1
    Like most of you probably, I'm doing 1080p exports of most things I'm working on. The first project shows a 1080p timeline with a mix of 4k, 5k, and 720p footage. Because zooming in so much on a 720p file in a 4k timeline looks so crappy, I'm doing 1080p timelines and scaling everything to the size it needs to be. I started in a 4k timeline then switched to 1080p because the 720p footage looked so terrible. However, in the 4k timeline, I didn't have any of the issues I'm showing in this first part of the video.
    When I switched to the 1080p timeline, I discovered a weird quirk: When I resize the 4k (or 5k) footage to the size it needs to be (which varies based on the frame I want), it goes back to the 100% view when I'm scrubbing through it. When I pause, the size of the video goes back to the way I set it. I show this in the video. Then I show what was my working solution for the time being: "scale to frame size", which brings all the videos to the size of the sequence frame size and works fine. Later, I turn off OpenCL in premiere and when I scrub through the video, it doesn't zoom back in or only stay at the size I set when stopped. For some reason all of these issues only happen at 50% scale or smaller. It doesn't happen at, say, 60%.
    I've tested this with raw R3D files and other 4K (or 5K) clips (even clips exported from After Effects) and the same thing happens. It doesn't seem to happen with 2.5k footage or 1080p footage.
    Issue #2
    This is the second project you'll see in the video.
    After grading in speedgrade (through direct link) I open my project back up in premiere and start playing it back. The video plays back with delays and frame drops. Now normally, this would be expected. But this is 1080p pro res footage, and this is just an effect added, and the yellow bar appears indicating that open CL should be accelerating the playback and it should do so smoothly.
    Maybe I was just wrong in assuming that a simple grade from speedgrade would be able to playback smoothly. I turn off the grade, and it plays normally.
    But then, when I turn off open cl and leave the grade on, the video plays back without ANY issues.
    So to me, it seems I'm still having issues with Open CL and adobe. I've found fixes that make it work temporarily, I don't need that kind of answer. However, I would like this to work. Is there something I'm doing wrong? Something I need to do to get this to work?
    Here are my specs:
    Mac Pro 6,1 (Late 2013)
    3 GHz 8-Core Intel Xeon E5
    64 GB 1867 MHz DDR3 ECC
    AMD FirePro D700 6144 MB (x2)
    OSX 10.9.4
    Firmware: 2.20f18
    What you're seeing is latest version of Premiere (CC 2014, v8.0.0 [169] Build)
    Everything here is ProRes 422, running from a Promise Pegasus2 R4 RAID (drives: 4x Seagate Desktop HDD 4 TB SATA 6Gb/s NCQ 64MB Cache 3.5-Inch Internal Bare Drive ST4000DM000) (that's thunderbolt 2).
    I've done everything: I've restarted my computer hundreds of times, I've reset NVRAM and PRAM and done power cycles.
    This isn't just some issue that started with 10.9.3 of OSX, the 4k issues happened when I first switched to a 1080p sequence back in February (2014) or so, which means it was an issue even with 10.9.2 and the previous firmware release.
    I've reported this issue to adobe.

    That crash appears to be casued by the Facebook plug-in.
    Create a new account (systempreferences -> accounts or Users & Groups on 10.7 and 10.8), make a new Library in that account, import some shots  and see if the problem is repeated there. If it is, then a re-install of the app might be indicated. If it's not, then it's likely the app is okay and the problem is something in the main account.

  • Mac OS X Server v10.7 does not show the ethernet link aggregated interface I created in Server Hardware Network Dialogue window. Are link aggregated ethernet connections not supported in Lion Server?

    Mac OS X Server v10.7 does not show the ethernet link aggregated interface i created. Does Lion server support ethernet link aggregated interfaces?

    Thanks for responding Cold--
    Hardware: Mac Pro  3.0 GHZ quad core xeon
    I read the link but it still does not explain why the aggregated dual ethernet interface does not show up in the Network tab of the hardware section Lion Server. I was able to see it on the network and looks to be using a single static IP that I assigned. My concern was that is this supported and will it allow for failover and double performance of the single network interface.
    Any thoughts?
    Thanks again!

  • I can't download movies.  I'm taking a cinema class where the professor provides a link to to a movie to be watched.  I am unable to access the link on my mac pro.  is there an app or software download that will allow me to do this?

    I can't download movies.  I'm taking a cinema class where I am required to watch movies.  My professor provides the link on an electronic blackboard for the movies.  I can't access the link on my mac pro notebook.  Is there an app or software download that can help with this?  I can access the link fine on a pc.

    The "right click" is a function of the OS and those keyboard commands do not work on the iPad at all with the built in virtual keyboard. I don't use an external keyboard - so I cannot attest to the possibility of that working - but there are no keyboard shortcuts with the iPad keyboard.

  • I have a Mac Pro using Lion, with a SSD for system.  Restored drive from backup.  Now logon password doesn't work.  Account password still works.  Changing password in user group preferences no longer works to change logon password.

    I have a Mac Pro using Lion, with SSD for system drive.  Drive stopped booting, but otherwise appeared healthy.  Restored from system backup.  Now drive seems to work properly, BUT my logon password no longer works.  Password OK for account; can access system preferences, and change user password there BUT logon still refuses to accept password.  No luck changing password for that account after adding new administrator account and logging on from that account.  Suggestions?  Thanks.

    If you redirect Accounts to another location (not on the Boot Drive) you need to direct them back there again after a restore.

    ... Unlock the lock, then hold down Control as you click on an Account to get access to the Advanced Options pane.

  • Hi Group: I think my "Macintosh H.D." disappeared off my desk top when I cloned the drive in setting up ext drive. The space at top rt corner went blank, the drive shows in disk utility, startup window, in the finder it shows up as "my Mac Pro'Help"

    Hi Group:
    In trying to set up an ext Drive for different purpose, I cloned my Macintosh H.D. drive and saved on another drive. Then I cloned the data on the Ext, used my orig. DVD to install sy on it, 4 attempts before it would accept the install. Did a reboot to confirm install no luck, and noticed that the space at top rt of D/T blank, the 2nd,3rd,& 4th bay Drives appeared below a blank space. My Mac H.D. appears in startup window & D/U but in finder Pref it is listed as " my name Mac Pro". The desk top has stayed the same, I can use startup to S/U  in all drives with a Sy, including Macintosh H. D. altho no icon or other clue that I am booted in it.
    During all my attempts with cloning and saving etc I think I made it invisible. I am not comfortable to try Terminal to find out. I will be totally thankful for all suggestions.
    I am using a Mac Pro (2008) with OS 10.6.8
    The external drive is on Firewire
    I used Disk Utility to set up drive
    I used  CCC to clone
    Thanks Funoptics

    go to finder preferences then side bar. make sure hard disk is ticked.

  • I have a new Mac Pro.  I want to use my old Mac Pro as a storage drive for photos and old documents, linked to my new Mac Pro.  How do I set up the old computer?

    I have a new Mac Pro.  I want to use my old Mac Pro as a storage drive for photos and old documents, linked to my new Mac Pro.  How do I set up the old computer?  Both computers have OS X10.9.3.  Currently they are connected by a Firewire 800 cable.

    You certainly could keep the old Mac Pro in Firewire mode (hold down the T key on its keyboard as you boot) to show its drives on the new MP. This is basically as fast as putting the drives into a Firewire enclosure.
    Or you could boot it normally and share its files over the network using the Sharing panel of System Preferences. If you turn on both File and Screen Sharing, you don't even need to have a monitor attached - you can do all administration using screen sharing. However, this method requires that you open all files over the network, which will be slower than the direct-connect method above, and may also not work with all applications.

  • Can I run two 2560x1440 monitors (dual link DVI) on a new Mac Pro?

    I have two Monoprice Zero-G IPS monitors, which can run at resolutions of 2560x1440 using a dual-link DVI adapter.  This is what I am currently using on my old 2008 Mac Pro.
    If i get a new model Mac Pro, could I continue this arrangement at the max resolution by using two Thunderbolt/Minidisplay port to Dual link DVI adapters (and, I assume, using two of the USB ports as I do now)?
    Frankly, I dont need the power of a new Mac Pro but my old one is long in the tooth.  I'd get a retina Macbook and use it as my desktop, but I cant think of any way to run both monitors at full resolution on the Macbook Pro.  I dont want to run them at HDMI resolution.
    Thanks in advance!

    Adapters go from $9 to $54, the latter having heat-sink which is not needed in an open cMP.
    Some support both as in either or but not two at the same time, SATA interface on the PCIe afapter, or an M.2 type
    While other PCIe "solutions" exist they are not OS independent or machine, the XP941 suffers from none of those concerns as it is bootable in all Mac Pro 1,1 thru 5,1, and is the only one for 200-7 models (and 2008 are iffy) so you can 'take it with you' if you move to a new cMP.
    Old controller, you need two SSDs in RAID0 to get 900MB/sec writes.
    Does not appear to be any of the real issues of PCIe slot and bus master, outside of you would exclude the 1x slot in the 2006 of course!
    The hardest part? getting these tiny M.2 blades, which are ~ 1" x 3.25" and have a tiny screw,  on the PCIe adapter.
    250GB SSD today are ~$120 + many do want SATA III PCIe (to get 550MB/sec and allow continued use of 4 x SATA II drive bays) runs ~$80-299. In some cases you then need a 2nd SSD. So if you want speed (vs size) then $240 + $100 and the $300 for XP941 256GB isn't bad.
    Finally, look for an Apple blade on ebay if running Yosemite - they vary, some are 2x (slow) M.2s and you want 4x but any are probably 700MB/sec and cost $400-700. No need with Apple part to worry about TRIM.
    Comparing 128GB SATA II $83 + $15 adapter vs PCIe XP941 128GB $140 + $24 is a 'toss-up' in cost but not performance, and one frees up drive bay and uses PCIe slot. (Generally 250GB are faster and better, the 128GB use to have 135MB/sec writes and $40 extras for 550MB and double storage makes sense, you never want an SSD to get down to 20% free, and you want to have 11% set aside for over-provisioning).
    So in a way you can get 1000MB/sec like nMP for $175-300 in any Mac Pro, and new faster blades are on the horizon offering 1400MB/sec.
    Kind of amazing, that M.2 support is in that old EFI all along waiting

  • Mac Mini Server Link aggregation - Thunderbolt or USB 3 gigabit ethernet adaptors

    I am setting up a late 2012 Mac Mini as a file server with Server 2.2. It has a Promise Pegasus R4 RAID and LaCie 4TB drives daisy chained via the Thunderbolt connection. 4 users on MacPro's will connect to the server to access these hard drives via gigabit ethernet.
    I imagine the gigabit ethernet will be the bottleneck, so I'm now looking at link aggregation. Not a problem on the MacPro's but the Mac Mini will require an adaptor to get a second gigabit port. From reading this forum I understand the Apple Thunderbolt to Gigabit adaptor will work, but I'm concerned that it will need to be fitted 3rd in line after the R4 and LaCie drives. The 10Gbps bandwidth Thunderbolt has, may cause another bottleneck with all three working off the same port?
    An option would be to use one of the USB 3 ports with this adaptor http://www.ebuyer.com/412005-startec...edium=products
    I believe it work with OSX, but I have no speed information or if OSX link aggregation will work using it.
    Any thoughts on the above would be appreciated and recommendations on a suitable Network Switch with LACP support welcome.

    At present Mountain Lion Server cannot use a LACP bond, in my experience only of course. http://www.small-tree.com/kb_results.asp?ID=59 describes LACP/Bonds do not show up in Server Admin GUI on Mountain Lion
    anyone know how to do it? or the location and the name of the plist file to configure the network interface in ML server?

  • Trying to link existing mac pro time machine backup to cloned startup drive

    Hi
    I have recently had to replace my startup drive on my Mac Pro as it was failing. I used SuperDuper! for this, and the clone is working fine as my new startup drive. I then went to run my next time machine backup (i backup to a time capsule), and time machine connected to the existing backup but wanted to backup everything as if backing up for the first time.
    So i did a bit of researching around, and found this hint:
    http://www.macosxhints.com/article.php?story=20090213071015789
    which changes the UUID registered with time machine, from the old drive to the new drive, so that it thinks that it's the old drive and carries on where it left off. i followed the instructions in the hint carefully and everything seemed to go right (i had to copy fsaclctl from an old leopard backup as it is missing in snow leopard). but when i ran the next backup again time machine wanted to backup everything.
    towards the bottom of the hint, there is a comment about the UUID generated under snow leopard, as follows:
    "I'm concerned that the output of xattr showed 37 hex pairs, not the 32 hex digits and dashes. By the looks -- I've forgotten all my ASCII -- it is a hex representation of the actual hex UUID (43 41 ...) and its dashes (2D), terminated with 00. That's arguably the same as the UUID, but not quite close enough to give me the warm & fuzzies"
    So if anyone can help me get this working right, using the method described in the hint, or some other method, i would be very grateful. Seems like my scenario isn't that uncommon (changing a startup drive), and it baffles me that there isn't a more straightforward way to make this work.
    thanks

    3. I am having troubles copying files(iphoto library) from my timemachine backup on to my imac.
    That's correct. Time Machine backups retain the original ownership and permissions. So one user doesn't have access to another user's data. Usually, that's a good thing.
    4. I don't need anything else except a few particular files, but everytime i try drag or copy it gives me the 'no privilege/permission error'.
    Your best bet may be to use +Migration Assistant+ to migrate the user account and selected data. Then log on as that user and use/copy the data as desired. See the pink box in #19 of Time Machine - Frequently Asked Questions (or use the link in *User Tips* at the top of this forum).

  • Linking SCSI baed flat-bed scanner to new Mac Pro with PCI-Express

    I need information on how to link my current scanner (Microtek Scanmaker 4) with a recently ordered Mac Pro. It is a SCSI based peripheral, and the only (last) of my currently owned peripherals that I'll need after getting my new Mac Pro. I've been searching the internet for a modestly priced interface board that would serve me.
    I've invested several hundred dollars in the hardware and SilverFast software, and would prefer to use the old scanner rather than move to a newer USB or Firewire based scanner.
    I'd appreciate any leads. Does Apple have advice? So far I've not found any discussions that face the issue, but perhaps I've missed a dark corner of the support search domains.
    Thanks in advance, Carl

    Thanks Michael:
    My dilemma is that a high end scanner for photographic images (up to 3900 lpi) and firewire/USB 2.0 compatible costs about $600. The card you suggest was priced at about $400.
    If push comes to shove I guess I'll opt for a new scanner, and face the problem of firewire/USB obselence when it comes.
    A local resource suggested that the only reason we even worry about the availability of SCSI devices is that they are needed to interface with multi-thousand dollar scientific instruments.
    I was hoping to find a more modestly priced card, and thank you for the lead. It's a start!

  • Link aggregated between NAS and a switch: the Mac as a very slow access...

    Hello,
    in my Office we're working with Macs and PCs and all the data is on a NAS.
    Here is our configuration:
    NAS <-link1->Switch<-Link2->Macs or PC.
    Macs are connected with AFP protocol (because SMB is very slow).
    We want to use Link Aggregation between the NAS and the switch (with 802.3ad procotol) but when we do that all the Macs have a very slow access to the NAS. But all is OK with the PCs.
    What can we do? Is there a problem with macOS X and link aggregation?
    Thank you for your help.
    Nicolas

    Sorry, not sure what the question is exactly.
    You must have an Xserve, or Ethernet cards capable of Jumbo Frames for one, I assume the Switch & NAS are capable?
    Possible clues...

  • Magic Mouse won't work on mac pro with d-link dongle

    For the first time I am very unhappy with a purchase of an apple product. I today have finally gotten 2 of those magic mice; one is a present for my best friend (who is also excited) and the other one I wanted to keep for myself. Not more to say as an introduction.
    Before I went back home I tried my mouse on one of my late 2007 macbooks, and after the mm update everything was great. I loved the handling, the style, simply everything about that kewl new gadget. I couldn't wait to get home to connect it to my "big boy", my mac pro, where I usually work on all my tasks in my office.
    Since my "bb" is already a bit older (one of the first intel xeons -- 2x2 dual core engines, already upgraded for several times with drives and RAM) and didn't come yet with the internal bluetooth module I have a D-Link DWB-120M USB dongle in use which always has been reliable and so far has connected anything that cried for a bluetooth connection. Till today...
    I installed the software update 1.0 on my big boy and started the recognition routine. The name of the magic mouse appeared, it tried to connect, but then broke up with something I've never seen before: "The pairing attempt was unsuccessful. Click "Continue" to try again."
    I clicked "continue" for several times, read all the trouble shootings around the globe, reconnected it to my macbook (where it still worked fine and said, batteries are 100%), and finally must face the fact that maybe the dongle (or the procedure with it) must be the reason for the failure.
    I am not really a dull-one; so I finally understand that the D-Link DWB-120M from 2004 might be inoperable in regard of the magic mouse. My bluetooth logi mouse still works with it, but I cannot make the magic mouse work at all.
    So I want to ask into the big bubble if there are people around who could make the new mouse work on on a xeon mac pro with only a usb dongle, and which dongle it would be.. I already tried the support pages of D-Link, but, hey, ...should I really install IE6 or 7 on my mac to get support there??? I guess not.
    Any hint is appreciated. I gladly will get myself a working usb dongle for my big boy, which would make the magic mouse work on it.
    Thanks for your attention. Please add your experiences to my thread; maybe they're more people who would love to take advantage of your experiences.
    ..Blinky shiny magic mouse awaits its first job on big boy..
    Take care
    P

    PS: I run 10.5.8 on all of my macs. I didn't upgrade to snow leopard yet, which I expect would not change anything until the mouse update has been done on all of my macs.
    Thanks again
