Dual link from CE to PE

I wonder how it can be done to connect dual link from CE to PE and have an active/standby function. Can it be setup by using RIPv2 between CE and PE? Please Help.

This can certainly be done using RIPv2. You just need to use the offset-list command to increase the metric on the updates received via the "standby" link. Here's a brief example:
int se0/0
description active link
int se0/1
description standby link
router rip
offset-list 1 in 1 se0/1
access-list 1 permit any
You also need to do the same on the PE side.
Hope this helps,

No Video from Mini-DisplayPort or DVI, only Dual-Link DVI

Just got my new Mac Pro 6-Core delivered. Out of the box, there were problems. I have a Dell 27" monitor that takes Dual-Link DVI, DisplayPort, or HDMI and a Dell 22" monitor that takes DVI, VGA, or HDMI. I am using a DisplayPort to Mini-DisplayPort cable to connect my 27" monitor to the Mac Pro and a DVI cable for my 22" monitor. I have the ATI 5870 graphics card installed OEM.
The problem is that the graphics card appears to not be switching to Mini-DisplayPort or DVI for output. It only works when I plug in a Dual-Link DVI cable to my 27" monitor. At that point, I get a video feed on my screen on a hard boot. At this point, I can then plug in my Mini-DisplayPort cable to my Mac Pro and unplug the Dual-Link DVI cable, and it switches video feeds perfectly. The problem then is that when I restart the computer, or power off and power on, the problem starts all over again. I HAVE to boot using the Dual-Link DVI cable for anything to work.
Ideas? Called AppleCare, waiting on engineering to see what they have to say. All the cables work perfectly when I plug them into my MacBook Pro (Late 2008). I am stumped.

I seem to be having similar problems. I bought the same system (6-core Westmere with the 5870 graphic card installed OEM) last month and I seem to be having problems running two Dell monitors which I know to be perfectly fine.
For the past month, I've been using a 24" Dell U2410 monitor with my Mac Pro using a DVI cable. Absolutely no problems at all. I then purchased another 24" Dell U2410 with the intention of running with dual displays. To prepare for this, I bought two mini-DisplayPort to DisplayPort cables from Monoprice. When I finally received the second display, I turned off the computer, hooked up both monitors through DisplayPort using the two mini-DisplayPort connections on the graphics card and turned on the system. I got two black screens. I tried to use keyboard commands to bring up the shutdown dialog box but it wasn't working. So I was forced to do a hard shutdown by holding down the power button for 10 seconds.
I went through a series of combinations of power cycles for the displays and computer and still two black screens. Finally, I went back to square one, a single display through a DVI cable. Again, a black screen. At this point, I disconnected the display from the computer. Power cycled the display (this initiates the self-test for the Dell display), hooked it up to the Mac Pro, turned it on, and it worked. I had one working display. Then I plugged in the second display using the mini-DisplayPort to Display port cable and that worked also. Finally, two working displays. For some reason, the Mac Pro recognized the display using the DisplayPort as the primary monitor. I rebooted the Mac Pro and the monitors continued to work properly. I booted into Windows 7 and again, no problems. I went back to OS X and used the computer for the night. When I was done, it put it to sleep.
This morning, when I tried to wake it up, same problems. I had to go through a series of power cycles and cable swapping to finally get a single screen to work.
I went through some of the troubleshooting documents here in the Support area and found this one:
http://support.apple.com/kb/HT4279
I am going to pick up the Apple mini-DisplayPort to DVI adapter and try running the display as two DVI monitors. Hopefully this will fix those problems. If the AppleCare engineer is able to give you anymore information, please let us know. This is a worrisome issue.

Mac Mini using dual-link to ACD 30" wake from sleep problem?

I have a new mac mini and rather new 30"ACD using the display port via dual link adaptor. The screen looks find but sometimes when I put the mini to sleep and turn the display off, and then turn the display on and wake the mac mini, nothing appears on the display. I don't think it is every time, but it occurs. I have my keyboard attached to the display with the usb connection, and so I can choose from the display options to turn the mac mini off or put to sleep when turning off the display manually. I have used this sometimes but prefer not to.
When the display doesn't show any image I have to hard shut down the mac mini, then start it up and leave the display on, then the image shows up.
Is there a solution to this? I don't mind using any one surefire way to wake the whole system wake from sleep. Either turn off or turn on the option where turning off screen also brings up option to put mac mini to sleep or turn off. Don't use that option at all. Attach the keyboard only to the mac mini directly, etc.
Any solutions would be appreciated.

What is the firmware version of your Mini DisplayPort to Dual-Link DVI Adapter? I've read many reports on how this particular piece of Apple kit is just not working properly (http://www.9to5mac.com/DisplayPort-Dual-Link-DVI-Adapter, http://foliovision.com/2009/12/20/apple-dual-dvi-mini-displayport-adapter-mb571z).
I've seen some people report that running firmware version 1.02 (or now 1.03?) solves their problems. I've also heard that people have had to resort to actually exchange their adapter in an Apple Store and hunt through new boxes to find adapters with the proper firmware version.

How do I get my Macbook Pro 15" to run dual monitor setup with Dual Link DVI outputs

I own have two 27" 2560x1440 WQHD LED IPS Computer monitors and have been trying to get them to work with my macbook pro 15" w retina for over a month now. I have purchased multiple products and nothing has worked. The big problem is that the only input that the monitors have is a Dual Link DVI input. The closest that i have gotten to getting them to work was this morning when I bought 2 Mini Display Port to Dual Link DVI Adapters for $99 a peice. Below is a link
http://store.apple.com/us/product/MB571Z/A/mini-displayport-to-dual-link-dvi-ada pter?afid=p219%7CGOUS&cid=AOS-US-KWG-PLA
Problem is that when I hook them up, I still only get a picture on one of the screens. Also, it requires you to plug into a mini Display port and USB port which takes up all of the space for me to run any othe peripherals. Though it has a built in USB port, when I plug my apple keybaord into it, I get an saying "USB Device Needs power, connect "keyboard Hub" to power or usb port on this mac"
I have looked everywhere for a docking station that would satisfy my needs, however, it does not exist. I use my macbook as my main office computer and take it home with me every night. I switched from the lenovo thinkpad to the macbook and have been satsified with my decision except for the fact that i cannot connect my monitors to it.
Please help!

Yes, that would work, however it would cost me $2000 for the monitors.

30'' Cinema Display with mini-display-port to dual link DVI adapter usb hub

Hi all, I don't know if any one of you experience this issue and can help me.
I am using an unibody macbook pro (late2008 model) to connect to a 30'' cinema display via the famous $100 mini diaplay port to dual link DVI adapter. I have connected the usb cable from the ACD to the adapter and the usb cable of the adapter to my macbook pro. This setting works fine under OSX 10.5.7.
When I am using Windows Vista under bootcamp the USB hub on the back of the ACD doesn't work. The device manager of Vista shows an excalmatory mark besides the device "Generic usb hub"; and it reports a problem of "the device cannot be started".
I doubted this problem is due to Windows cannot recognise the $100 adapter as a "generic usb hub"; and apple has not release a driver for this $100 adapter for windows.
Since my MBP only has 2 usb ports and the $100 adapter already occupied one, it would be very much helpful if the usb hub of the ACD can work just like in OSX. Can anyone think of any suggestion?
Much appreciated for reading this post and thank you.

i don't have an answer for you, but i feel your pain. very frustrating when this happens with Apple products and Vista/Bootcamp. wish they were more compatible, for it would make things so much easier for the consumer.

Apple's Mini Displayport to Dual link DVI Adapter... What to do?

So i'm doing a new setup with 6 monitors (Eyefinity 6), and i've got everything set up so far... Except for adapters. So i went and got 4 Of those Accel MDP to DVI SL adapters, in addition to the two passive that come with a card. Didn't work...
So i got two Apple Mini Displayport to Dual Link DVI Adapters... And boy, I should have read the reviews before buying them. They are giving me very strange issues. Not going above 800X600, serious graphics corruption on the monitors connected to the apple adapters, or odd resolutions that the monitors do not support.
So i'm wondering what to do. If possible, i'd like to get these to work somehow, as i got them for cheaper than other MDP to Dual Link adapters. They are both plugged in to the USB ports of my mac pro.
I've also heard something about a firmware version, 1.2 or something. Is there a way to update the firmware of these?
Thanks
-C

I'm using the Sapphire 5870 Eyefinity 6 Edition. Two of them in crossfire, supplied their power from an external 1200W PSU Devoted just to them.
It's under Windows 7, running on my mac Pro 2.26.
Hooking them both up to a iphone cube-wall charger keeps them up and running, but they fail to supply the necessary resolution (One only registers 640X The other dimension, the other thinks the monitor is 1920X1080, when it really is 1920X1200).
Not to mention, attempting to use any of them in an extended desktop led to a MACHINECHECKEXCEPTION bsod.
I can't find any sign of what the whole issue is, i'm having issues with the eyefinity setup itself too, so i dunno if its the adapters, the card, drivers, or what. The apple adapters are acting up on me though.

HT1338 Dual Link DVI Adapter Doesn't Work

I have a brand new MacBook Pro with Retina which replaced a 17" MacBook Pro. The 17" machine was connected via an Apple-branded Dual Link DVI adapter to a Dell 30" (2560 x 1600) external display - the best I can get the MacBook Pro/Retina to do is 1600 x 1000 using the same adapter that the 17" was using.
I have run all system updates - including one that was targeted at stability/support for external monitors - still cannot get better than 1600x1000 resolution.
Any advise?

Didn't find this answer on a general search, but once I submitted my post, the MORE LIKE THIS bar (right side of screen) showed up and gave me the answer! See below:
Update from Applecare: this problem made its way to engineering and they pointed out a 'hidden' way to fix this with no special 3rd party software:
When you bring up the resolutions for a given display, as its set to 'best for display' hold down the 'option' key while clicking 'scaled'. The scaled menu should now show all the resolutions supported by the monitor. On my Dell it shows 2560x1600 and everything works fine when I select that.
I held down OPTION and re-clicked SCALED; all resolutions came up and I'm now good to go!

Problem w/New MacbookPro, Cinema 30, Mini DisplayPort to Dual-Link DVI Adap

Hi, I have a new MacBook Pro with Miniport connected to a Cinema 30 using the Mini DisplayPort to Dual-Link DVI Adapter. I upgraded from the previous version of the Macbook Pro w/built-in DVI and never had a problem.
From the moment I started using this new miniport adapter with the Cinema 30, I noticed intermittent graphic anomalies. Most of the time, discolored lines will start rapidly popping in and out across the screen - especially noticeable with dark backgrounds. Here are a couple of quick videos that visualize the problem.
Video 1 - http://is.gd/krM6
Video 2 - http://is.gd/krLT
I'm also experiencing issues with the cursor randomly jumping across the screen.
It's isolated to the 30 cinema and the adapter. The Macbook Pro works fine when connected tot he new 24" LED Cinema.
Any advice on what to do? Is it a faulty adapter? Is there a SW/Firmware upgrade?
Thank you!

I'm having the exact same problem. Have you called Apple and if so, what did they say? I read in a magazine that you can switch to the NVIDIA GeForce 9600M GT graphics processor some how with in our computer. I don't know how or if this may solve the problem.

MBP + Mini DisplayPort to Dual-Link DVI Adapter + 30" = blue flickering

Hi everyone,
I was wondering if anyone has found a solution to this problem? I use an Apple 30" Cinema Display and it worked fine with my Late 2007 MBP. Now I got a new Core i7 MBP and the Mini DisplayPort to Dual-Link DVI Adapter. At first all works fine, but after a while of use I get blue (and sometimes also green) flickering pixels in areas that are supposed to be black. This does usually not matter while working, but watching movies for example is completely unbearable.
I’ve read a few threads, but most seem to have different problems like 1/3 of the screen flickering or the external display going completely off for a second. That is no issue over here. It is just that the longer I use my setup the more flickering gets added. At first I thought I don’t suffer from this, because it goes from practically flicker-free to totally weird flickering when everything is in use for more than a few minutes.
I’ve set up the Computer Name screensaver. If I run it right after turning on my MBP all is fine. Running it again after 2-3 minutes of use shows the first blue pixels flickering. It does not need 30 minutes to arrive at what seems like more flickering isn’t possible anymore...
Any recommendations or solutions are really welcome!
Things I already tried:
- different USB ports for both the adapter and the Cinema Display
- other power outlets
- powering the adapter from a USB hub or via an iPod wall charger
Thanks
Björn

I would even try out crazy adapter combinations if there were any available...
At last! I’m quoting myself, because I finally found an alternative adapter which works! I have no more flickering pixels/lines. Black looks and stays completely black as it should! I can finally use dark backgrounds again and watching movies with black borders or dark areas is no longer a pain.
The adapter was very hard to get. It currently is not sold here in Germany and I got it off eBay where there was only 1 available. I’m happy, because I got it for less than 90€ which is even a little cheaper than Apple’s flicker-creator.
The adapter I now use is the Sapphire Active DisplayPort-to-(Dual-Link-)DVI adapter. It has a USB connector for power like Apple’s adapter. The only thing that’s added is the DisplayPort-to-Mini-DisplayPort cable since it is not available with Mini-DisplayPort. Here’s a picture of it:
Hope this helps others, too!

PS: This adapter seems to be normally meant for ATI’s GPUs in order to connect 3 displays which they call Eyefinity.

TS3232 I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have screen flickering issues

I have the mini DisplayPort to Dual-Link DVI Adapter firmware 1.03 and I still have massive screen flickering issues on a Mac Mini 2012.
I am using a Dell 30" monitor (it's the Samsung screen just rebranded) connected to a WD 4TB Thunderbolt drive connected to the Mac Mini.
The screen is usable for the most part when I've just started the computer (although today I started having issues after a fresh restart) but if even just the screen goes to sleep, or the computer goes to sleep and I wake it later, I start to have massive flickering to black and occasionally to snow.
The effect seems to be more likely to arise when I'm on heavy graphics-intensive websites or programs (eg, Tumblr feed with lots of GIF images or working in Adobe Premiere), but once it starts shutting down those programs has no effect, the screen keeps flickering wildly.
The problem improved after the 1.03 firmware upgrade (for a while it was flickering uncontrollably ALL the time and was virtually unusable) but it has not gone away.
Any suggestions would be very welcome, either for how to fix this issue or how to get Apple to, you know, let me TELL THEM that their adapter firmware fix has NOT solved the issue, since my phone support has expired. :/

I have a new Mini DisplayPort to Dual-Link DVI Adapter to allow my original Apple 30" Cinema Display to connect to the new Mac Pro. Shipped straight from Apple, it is firmware version 1.03. I've never had flickering issues, but the display will often go black (possibly after a screen power save) and not come back. when this happens I am still able to connect to and use the Mac via remote connection. But the only way to get the screen back is either to unplug the adapter and plug it back in to the Mac, or to shut down and power up the Mac. This may be a separate issue, so I'll also post it standalone...

Mini Displayport to Dual-Link DVI Issues on 30" Cinema Display

I know this problem has been around for a while, and that there are several other discussion on it, but my goal here is to point out that even in mid-2011, this issue remains.
Here's my configuration:
30" Cinema Display
Dual-link MDP to DVI adapter with 1.03 firmware (purchased August 2011 from an Apple Store)
New-ish MacBook Pro (purchased December 2010) with Mini Displayport
Symptoms:
On dark areas of the screen, DVI noise appears (horizontal flickers of light coming and going at random)
Attempted Fixes:
Unplugging the display and plugging it back in to the computer (failed)
Restarting the computer (failed)
Tightening the connections on the Dual-Link DVI adapter (failed)
Sleeping the display and awaking it (failed)
Some suggest getting a new 27" Cinema Display with native Mini Displayport/Thunderbolt support. I actually have one, but I cannot tolerate the glare on the glossy displays, so I'm "downgrading" to a 30" Cinema Display.
Is there any remaining hope for this issue?

I still cannot understand why you would return everything... Ultimately you want this computer right? Once the bugs on the adapter are fixed are you gonna go back and re-buy it?
Seems like a lot of time spent out of spite and not for good reason. Me, this is the best Mac I've ever owned (and I've owned many. no, really.) and I'm happy to wait for this adapter w/ this machine in stead of going back to my other box.
I observed a similar client of mine w/ an iPhone... after the first week, he didn't like the keyboard and a few other things, so he took it back and went back to using his Blackberry -only to dump the Blackberry again for the iPhone, because he realized that the iPhone still did more things better than the Blackberry.

Mini DisplayPort to Dual-Link DVI Adapter 1.03 - screen goes black and won't come back

I have a new Mini DisplayPort to Dual-Link DVI Adapter to allow my original Apple 30" Cinema Display to connect to the new Mac Pro. Shipped straight from Apple, it is firmware version 1.03.

Mini displayport to dual-Link DVI Adapter - flicker issue resolved

I have a late 2013 Imac 27 inch and I had a 30" Dell 3007wfp as my second monitor on the standard DVI adapter for a while at low resolution. I finally got off my behind and bought the mini displayport to dual-Link DVI Adapter... I was excited to see it in all it's glory. It immediately started flickering wildly and I thought I'd do some reading to see how I could resolve it. Pointers to making sure the adapter was version 1.03 didn't help.
http://support.apple.com/kb/ts3232
I already had it. I was getting ready to bite the bullet and just take it back when I decided to see if I had another DVI cable to swap the one I was using out "just in case". I found another one.. same length. Darn it. Then I noticed the DVI cable diameter I was using was significantly thinner than the one I found in my box of etc... What the heck? I thought.
Connected it and BOOM! Vivid colors, high resolution, no more flickers!! Issue gone. Happy days!
Thought I'd post this to possibly help the next schmoe who is in the same situation

Mini DisplayPort to Dual-Link DVI Adapter

Hi, I am using the Apple Mini DisplayPort to Dual-Link DVI adapter to connect my 30" Apple Cinema Display (Aluminum) to my MacBook Pro 13" Retina, I am passing through the Belkin Thunderbolt Dock, so I connect the Dock to the MBP via the Thunderbolt port and then I connect the Mini DisplayPort to Dual-Link DVI adapter to the Belkin Dock and then to the Apple Cinema 30".
One of the issues I am having is that with the Cinema Display I am working at 2560 x 1600 resolution, much larger than the native MBP resolution, I am also using my apps in Full Screen mode, so when I disconnect from the Cinema Display and go back to use the MBP the apps in full screen mode still are at a higher resolution than the native MBP resolution and they are off the screen. Is there a way to manage a profile with different resolution so the Mac OS will switch automatically resolutions?
Also does the Apple Mini DisplayPort to Dual-Link DVI adapter usb cable supports USB 3.0 ?
Thanks

Hey guys,
I found out an answer by myself...
The missing link : the MacBook Pro needs to be powered... as in you need to plug the charger in...
In conclusion, you simply plug everything, turn on the MacBook Pro, close the lid, and there you go !
