ISE question on desktop switches, MAC replace, MAC move

Hi all,
few questions on authenticator NAD (example: switch) to support on these items
01. desktop switches, how we can enable other switch to plug in and extend the network? What is this deal with Network Edge Access Topology (NEAT)?
what must configure on ISE policy node, authenticator switch and the new plug in extended switch?
02. How and what need to do on authenticator switch and ISE on these:
a. MAC Replace
b. MAC Move   
Thanks
Noel

Before you consider NEAT -
If you are using a dumb switch you can enable multi-auth so that all mac  addresses forwarded up to the switch port are authenticated, dynamic  vlan assignment is not a scalable solution for this solution since you  can only assign the first authenticated mac address to the dynamic vlan,  others either inherit the vlan or error disable the port (I can't  recall), but it is documented.
NEAT is only supported on a few access or distribution switches, so make sure you follow the release notes to see if you platform supports this design.
ISE policy node - must have the av-pair of device-traffic-class=switch to be configured to dynamically convert the authenticator's port over to a trunk port. Your design depends on either MAB or dot1x to succeed for this av-pair to be triggered in your authorization policy...i.e. profiled endpoint group or a user group with the credentials mapped to a user group or both.
Authenticator switch - must allow radius authentication, authorization, and for proper license tracking an accounting.
Client switch - credentials (see reference guides and config examples), forward traffic to trigger mab if dot1x is not part of this solution.
Thanks,

  • Is it possible to run dual display monitors on a KVM switch between my mac mini and a PC desktop?

    I have two 23" monitors utilizing DVI that I currently have plugged into my PC desktop.  I'd like to purchase the mac mini and utilize the same monitors for both systems and switch back and forth between the two.  So, I'm wondering if it's possible.  The only two hangups I can anticipate is dual display capability on the mini (I expect that some adapter will be necessary), keyboard compatibility between the two systems, and finding a switch that will handle all the above.  Any help would be greatly appreciated!!!!

    I think this video could help you

    We need to get you moved. This forum is for mini-tower Macs built between 1998 and 2005 and doesn;t get as much traffic ("eyeballs on the problem") as the forums for newer Macs.
    Please do "About this Mac" from you Apple menu and tell us what that says for "processor" and Mac OS version. Looks like this:
    or this for later Mac OS versions:
    With that we can figure out which of the two iMac forums you need and get the Hosts to move your post.

  • Questions before I SWITCH to Mac...

    Few questions before I switch to Mac (hoepfully when Leopard comes out)....
    Currently I have a Dell XPS Media Center PC and a Vista laptop.
    1. TV/DVR CAPABILITIES: I love using my PC as a tv tuner & DVR. Does mac have this capability? If I run Vista on the Mac will my Media Center, TV tuner, etc... run the same?
    2. PDA SYNC: Will the Mac sync calendar & contat items with my Windows based PDA?
    3. WEB DEVELOPMENT: I am a ASP.NET developer. Can I do this on a mac easily? If I have to use Windows on the mac to do this, can anyone speak on the performace?
    4. SHARING FILES BETWEEN OS & COMPUTERS: Can I share files with other XP or Vista pcs I have in the house? Can I share files between the Mac and Vista OS on the SAME machine?
    5. DUAL MONITORS: Does the MacBook Pro or iMac support DUAL monitors?
    6. CS3 QUESTIONS: I'm thinking about purchasing Photoshop CS3, Flash CS3, etc... Can I install them onto the Mac side and the Vista side of the same machine?
    Thanks! I was a PC lover, but now I'm turning into a MAC LOVER!!!!
    Thanks everyone!!!

    1. No way to tell. You'd have to install the card and the drivers too see if they work.
    2. http://www.markspace.com/missingsync_windowsmobile.php
    3. You'd have to install Windows if you want to develop for .Net
    4. Yes and yes
    5. Yes
    6. You'd need to buy both Mac an PC versions of CS3

  • Parallels Desktop 5 or Parallels Desktop Switch to Mac ?

    I recently bought my first Mac (Macbook Pro 7,1 and plan to port some of my Windows applications into a Parallels virtual machine. The Mac specialist who sold me the package included Parallels Desktop 5 for Mac. Upon reading the installation instructions I learn that there is a different program, Parallels Desktop Switch to Mac. Would that be better for my needs? Should I exchange the one I have for a Switch to Mac?

    Welcome to Apple Discussions
    Parallels Desktop 5 will allow you to install a virtual machine for Windows onto your mac provided you have a copy of Windows and a serial number available. You will be starting from scratch so will have to install your applications again and move any data folders/files across to the new locations.
    If you want Tutorials on how Mac's work and some extra migration tools then Switch to Mac might suit you better (but IMHO it's not worth it)

  • I switch on my mac book pro and all i get is the apple logo and below a loading wheel , but its stuck there for like an hour !!! help??

    i switch on my mac book pro and all i get is the apple logo and below a loading wheel , but its stuck there for like an hour !!! help??

    Take each of these steps that you haven't already tried. Stop when the problem is resolved.
    Step 1
    The first step in dealing with a boot failure is to secure your data. If you want to preserve the contents of the startup drive, and you don't already have at least one current backup, you must try to back up now, before you do anything else. It may or may not be possible. If you don't care about the data that has changed since your last backup, you can skip this step.   
    There are several ways to back up a Mac that is unable to boot. You need an external hard drive to hold the backup data.
         a. Boot into the Recovery partition, or from a local Time Machine backup volume (option key at startup.) When the OS X Utilities screen appears, launch Disk Utility and follow the instructions in this support article, under “Instructions for backing up to an external hard disk via Disk Utility.”
    b. If you have access to a working Mac, and both it and the non-working Mac have FireWire or Thunderbolt ports, boot the non-working Mac in target disk mode. Use the working Mac to copy the data to another drive. This technique won't work with USB, Ethernet, Wi-Fi, or Bluetooth.
    c. If the internal drive of the non-working Mac is user-replaceable, remove it and mount it in an external enclosure or drive dock. Use another Mac to copy the data.
    Step 2
    If the startup process stops at a blank gray screen with no Apple logo or spinning "daisy wheel," then the startup volume may be full. If you had previously seen warnings of low disk space, this is almost certainly the case. The easiest way to deal with the problem is to boot from an external drive, or else to use either of the techniques in Steps 1b and 1c to mount the internal drive and delete some files. According to Apple documentation, you need at least 9 GB of available space on the startup volume (as shown in the Finder Info window) for normal operation.
    Step 3
    Sometimes a boot failure can be resolved by resetting the NVRAM.
    Step 4
    If you use a wireless keyboard, trackpad, or mouse, replace or recharge the batteries. The battery level shown in the Bluetooth menu item may not be accurate.
    Step 5
    If there's a built-in optical drive, a disc may be stuck in it. Follow these instructions to eject it.
    Step 6
    Press and hold the power button until the power shuts off. Disconnect all wired peripherals except those needed to boot, and remove all aftermarket expansion cards. Use a different keyboard and/or mouse, if those devices are wired. If you can boot now, one of the devices you disconnected, or a combination of them, is causing the problem. Finding out which one is a process of elimination.
    Step 7
    If you've booted from an external storage device, make sure that your internal boot volume is selected in the Startup Disk pane of System Preferences.
    Boot in safe mode. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Post for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including wireless networking on certain Macs.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
    When you boot in safe mode, it's normal to see a dark gray progress bar on a light gray background. If the progress bar gets stuck for more than a few minutes, or if the system shuts down automatically while the progress bar is displayed, your boot volume is corrupt and the drive is probably malfunctioning. In that case, go to Step 6.
    If you can boot and log in now, empty the Trash, and then open the Finder Info window on your boot volume ("Macintosh HD," unless you gave it a different name.) Check that you have at least 9 GB of available space, as shown in the window. If you don't, copy as many files as necessary to another volume (not another folder on the same volume) and delete the originals. Deletion isn't complete until you empty the Trash again. Do this until the available space is more than 9 GB. Then reboot as usual (i.e., not in safe mode.)
    If the boot process hangs again, the problem is likely caused by a third-party system modification that you installed. Post for further instructions.
    Step 8
    Launch Disk Utility in Recovery mode (see Step 1.) Select your startup volume, then run Repair Disk. If any problems are found, repeat until clear. If Disk Utility reports that the volume can't be repaired, the drive has malfunctioned and should be replaced. You might choose to tolerate one such malfunction in the life of the drive. In that case, erase the volume and restore from a backup. If the same thing ever happens again, replace the drive immediately.
    This is one of the rare situations in which you should also run Repair Permissions, ignoring the false warnings it may produce. Look for the line "Permissions repair complete" at the end of the output. Then reboot as usual.
    Step 9
    Reinstall the OS. If your Mac was upgraded from an older version of OS X, you’ll need the Apple ID and password you used to upgrade.
    Step 10
    Repeat Step 9, but this time erase the boot volume in Disk Utility before installing. The system should automatically reboot into the Setup Assistant. Follow the prompts to transfer your data from a Time Machine or other backup.
    Step 11
    This step applies only to models that have a logic-board ("PRAM") battery: all Mac Pro's and some others (not current models.) Both desktop and portable Macs used to have such a battery. The logic-board battery, if there is one, is separate from the main battery of a portable. A dead logic-board battery can cause a boot failure. Typically the failure will be preceded by loss of the settings for the startup disk and system clock. See the user manual for replacement instructions. You may have to take the machine to a service provider to have the battery replaced.
    Step 12
    If you get this far, you're probably dealing with a hardware fault. Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.

  • If I switch over to Mac from PC will I be able to use my Quickbooks pc version or Adobe photoshop cs?

    Will Quickbooks pc versions work on Macs or will all my software have to be replaced? Will make the switch to Apple soon and trying to anticipate process. Also have Adobe photoshop CS and Quicken. Any suggestions or advice appreciated.

    Hello Herbert258,
    Short answer: No.
    Long answer: You have to buy the Mac versions for applications, kind of like Adobe Photoshop. If you want to keep your applications (and save some $$$) you can install Windows on Mac using boot camp. There are programs out there like Parallels where you can run windows on your desktop of your future Mac. You still need a copy of Windows to install, and Parallels is about $70.
    Best of luck,

  • Help to set up network: XP Home OS desktop & mac mini (Mac OS/  XP Home OS)

    Hello!
    I’d be grateful for advice on setting up a home network.
    I’m a total newbie to MAC OS Leopard, so please excuse my lack of knowledge!
    Background:
    - Livebox (residential internet gateway)
    - XP Home OS Desktop pc (has wired connection to Livebox)
    - MAC OS Leopard Apple Mac Mini (has wireless connection to Livebox)
    - Mac Mini also has a Windows partition with XP Home OS (has Boot Camp and Fusion installed).
    I want to set up a network between the desktop pc and the Mac Mini so I can back up the two hard drives on a shared area, share files, and share the printer.
    I have successfully connected the Mac Mini wirelessly to the Livebox (and the internet) via its Airport- obviously on the MAC OS side.
    I would like to be able to log into either the Mac OS side or the XP Home side to work on files stored separately in each side. However, I also would like to share files between each side of the mac.
    Is there a way the XP Home OS side of the Mac Mini able can access files created on its other, MAC OS side, and vice versa? (would this mean sharing via the network, without physically having to switch between the two sides of the mac itself?)
    Consequently, how do I set up the network to share files etc. between the XP Home desktop pc and the Mac Mini (both stored on its XP Home OS side and its Mac OS side)?
    Would this mean I set up the network as having 3 individual connections:
    1. the XP Home desktop & 2. the XP Home side of the mac & 3. the MAC OS side of the Mac?
    If so, how do I set up this network?
    I am sure this is much simpler than I have made it sound!!! ;-(
    Any comments gratefully received.
    Thank you all in advance.

    Will i have to reinstall
    both OSX and Windows, or will Parallels run with the
    already installed Windows xp through bootcamp?
    No you can use the bootcamp partition and windows xp directly through parallels.
    Second question, i have never installed Windows on a
    Mac, so i'm not really sure what to do, so can
    someone give me some good tips on this?
    First get OSX installed. Then you can look at this for getting help and downloading the latest version of bootcamp.
    http://docs.info.apple.com/article.html?artnum=303572
    When i install the new HD, do i install OSX as i
    would normally, and then install Bootcamp, or will
    installation be different than the regular
    straight-forward install?
    Install OSX. Bootcamp is then installed into OSX and you run it from there to do the bootcamp setup.
    I'm guessing that i will have to partition the drive
    to run both OS's, but how will i go about doing that?
    And how much disk space should i give each OS? I
    have 160GB so maybe 50GB to Windows and 110GB to
    OSX?
    Bootcamp installer in OSX will partition your drive so you don't need to worry about it yet. I would suggest at least 15 GB , more if you are going to be runnin lots of windows programs.
    Btw, i'll be using superduper to make a copy of my
    current HD, but i dont know what to do with it when
    installing the new HD and OS.
    Where are you making the copy of your hard drive at? If it is an external drive you can make it bootable and then you can restore from it on the new drive. Saves a lot of time and trouble.

  • HT1533 How can I switch back to Mac OS X from Windows 7 Bootcamp?

    I'm having problem switching back to Mac OS on my Macbook Air.  It's currently running Windows 7 bootcamp without a Mac OS installed with it.  I tried booting up on Mac OSX installer disc (Snow Leopard) on the external CDROM drive but it boots to Windows instead.  I tried the Boot Camp Control Panel on Windows and Restart to Mac OS X but it could not find an OS X intalled and I tried changing the startup disc to the installation disc on the CDROM and restarted but still goes to Windows.
    Please HELP!
    Thank you.

    The MBA did not ship with an OS on DVD because they don't have an optical drive. There are two kinds of OS disks - commercial release, which for Snow Leopard is 10.6.3 I believe, and machine specific. If your SL disk is gray it isn't going to boot your MBA because it isn't made for the MBA. If your SL disk has a cat on it look at what specific version it is. As I said, I think it is 10.6.3 and while I wasn't able to find out what specific OS version your MBA shipped with, I'm pretty sure it was a version later than 10.6.3 and if I'm right your disk isn't going to boot the computer. You'll need to either contact Apple for a valid replacement installer or find someone with a Mac who can make a valid installer on a USB drive or DVD.

  • Workflow Question - Recently moved from PC to Mac

    So, let me say that I'm a die hard Windows user -- in fact, in my "day job" I own a software development company and we're a "Microsoft shop". But, my side business is Photography and I'm making the switch to the Mac & Aperture. So, what I'm hoping to get from this post is a "yes, you can do that" or a "no, you can't do that" with Aperture. I'm happy to figure out how -- I just need someone to tell me if it's possible.
    Here's my current workflow (coming from the PC - which required several applications to accomplish these steps):
    1) Import images and rename "IMG_1234.CR2" to "1234.CR2" -- essentially dropping the "IMG_" from the name. Is this possible w/ Aperture?
    2) Do all of the processing on the images (No questions here yet -- got that pretty well figured out in Aperture).
    3) Create a black & white version of each image. Currently doing this by making a duplicate version in Aperture. But, I would like it to be named "1234-BW.CR2" rather than just have "version 2" tacked on the end. Is this possible in Aperture?
    4) "Develop" the pics into jpg's. Again, the final image names should be "1234.jpg" and "1234-BW.jpg" respectively. Again, the question has to do with renaming the original & duplicate version of the image.
    5) Choose all of the color versions of the photos and then selectively pick some of the b/w versions and export them to a "Web" size along w/ Thumbnail versions that will be posted on my web site. (Again, this should be easy if I can name things like I want them to be named in question 3 & 4.)
    So, right now I'm the biggest thing that I'm having a problem with in naming the images -- how flexible is Aperture with this? I've tried to customize the naming but can't see to figure out how to simply remove the "IMG_" when importing and then how to tack on "-BW" when creating a duplicate version.
    So far I really like Aperture -- it will ultimately save me from having to use 5 different applications on the PC and thus greatly improve the efficiency of my workflow. There are some things I've noticed that would be nice -- for example, on the PC I used a program called Bibble Pro to "develop" my Canon RAW files. Bibble is a little smoother (read faster) when making some adjustments. For example, when I'm in full screen mode and adjust the exposure, contrast or sharpening Aperture is not as smooth and "real-time" as Bibble. (And, the Mac I have is the top of the line iMac made today w/ 2GB of RAM. So, I would assume that processor speed is not an issue.)
    Anyway, if you have any insight into this post please let me know. Thanks in advance for any help you can provide... If you want to see my web site to understand what I'm doing the URL is http://www.level3photography.com/proofs.aspx
    Thanks again!

    would assume that processor speed is not an issue...
    Many folks from other disciplines think that applications should, well, just run on any computer. Not so with graphics apps. Photoshop, for instance, slows if not provided a second physical hard drive for scratch disk; Aperture craves GPU hardware; both gobble RAM; etc. Existing PSCS2 Photoshop performance improves up to 8 GB RAM, and we have not yet empirically determined the max amount of RAM Aperture will benefit from but it certainly is more than 2 GB.
    iMacs are consumer machines, not pro graphics boxes, even though many folks successfully use them as such. And, "top of the line iMac made today" would include not the 7300 GT graphics but the 7600 GT graphics card and 3 GB of RAM rather than 2 GB.
    All that said, your iMac should run Aperture well if you keep the box well maintained. Just don't be surprised if you do see some hardware imposed limitations.

  • I'm a Pc user wanting to switch to a Mac. . .

    Hi, I currently am sharing a PC with my brother. We both use it a lot and one computer isn't big enough for the two of us. So i was hoping to buy a Mac Mini. Only problem is, I don't have that much money to spend. Because I also need the money for a keyboard, mouse and monitor.(I know everything is expensive and I didn't expect to pay $200, I do know the value of a dollar.) So I can probably only afford the 1.5GHz Intel Core Solo. And I'm not a genius when it comes to some things and I'm new to Mac's so I have some questions.
    1. 1.5GHz Intel Core Solo processor vs. 1.66GHz Intel Core Duo processor?
    2. Can I get a 1.66GHz Intel Core Duo processor installed later on if I start out with the 1.5 Solo?
    3. If so, how much $$$ will it cost me?
    4. Combo drive (DVD-ROM/CD-RW) vs. Double-layer SuperDrive (DVD+R DL/DVD±RW/CD-RW)?
    5. 512MB memory (667MHz DDR2 SDRAM): how much $$$ to upgrade to 1GB memory?
    I hope for a reply as soon as you read this.

    hey, its fantastic your switching to a mac!
    to answer your questions
    1. 1.5GHz Intel Core Solo processor vs. 1.66GHz Intel Core Duo processor?
    In terms of performance the extra .16 GHZ power would not be worth it unless you are running professional programs (in which case dont look at a mac mini)
    2. Can I get a 1.66GHz Intel Core Duo processor installed later on if I start out with the 1.5 Solo?
    THe processor is soldered directly to the motherboard (or as mac call them "logic board") so an upgrade will be nearly impossible
    3. If so, how much $$$ will it cost me?
    sometimes you can find a new logic board at a spares supplier, unless you are a good electro-head i would stay clear, a lot of hassle changing one
    4. Combo drive (DVD-ROM/CD-RW) vs. Double-layer SuperDrive (DVD+R DL/DVD±RW/CD-RW)?
    do the same job but the superdrive will burn your dvds, if you copy dvd films then you will be disappointed coz theres no software to do this.
    if you burn data to dvds then i would go for it, external dvd drives arent good for macs, external hard drives are fine.
    5. 512MB memory (667MHz DDR2 SDRAM): how much $$$ to upgrade to 1GB memory?
    apple will charge you a fortune for this, probably about $100. if you are farmiliar with the inside working of a pc, it is cheaper to buy some on ebay, DDR2 is the stuff you want. But if you cant fit it your self and you dont know anyone who can, best to get it from apple
    any other questions, just holla
    Peace y'all

  • Will this version of XP Home work for Parallels Desktop 3.0 for Mac?

    For Christmas, I received Parallels Desktop 3.0 for Mac because I need Windows XP for certain reasons. First, I have several neat programs that only run on DOS and second, I miss MS Paint (I hate Seashore or Piantbrush) and Finally, I like MS Movie Maker better then iMovie. When I opened it, I got furious because found out that XP Home doesn't come with it, so I must purchase it online. I really need XP Home with SP2, and not XP Pro. I looked in the manuel and it says I cannot use OEM copies, but I looked at another discussion that said OEM copies were OK. Now I'm very confused, so I decided to make this post hoping that I can get a good final answer. Here is another problem, I only have $100 to spend because I'm saving up for a bigger gift that has nothing to do with computers. I want to know which copy will work.
    Copy No.1

    If you know a better copy under $100.00 that will be even more compatible with Parallels, tell me.
    Thank You and I hope you can answer my questions.

    You have an intel based mac. that is one particular Original Equiptment Manufacturer. Now, what parallels does is build a vitual machine inside your mac to make it OEM compatible inside the mac Operating System to make Windows XP Home to work within the mac environment. Once it is fully installed, you can use mac and windows XP home together at the same time. You can also install XP home in mac boot and use it separate from mac as well to do your work separate of being on mac ss well. carefully read the instructions and the key part again is putting in P.T, for it to work properly.

  • Palm Desktop 4.1 for Mac OS & iQue 3600?

    I also have the exact same problem with my early 2008 Mac Pro.  Last spring, the video card that came with the unit burned out.  I brought it in to the Apple Store in my area, but they were unable to really help me out.  I ended up replacing the card, but about two or three weeks ago I started having the same exact issue that you do - the Mac would suddenly die occasionally, and then would take quite a few tries to come back up.  It seems that resetting the PRAM helps temporarily with me.  It has been up since about 3 PM so far, and it is behaving.
    My main issue is that replacement parts are expensive for this machine.  If I were to replace the power supply and the logic board, Apple would charge me about a thousand bucks!  That's simply too much money to drop on a 4 year old computer.
    My solution is that I will run it for a while longer, and replace it with the Mac Mini with the ATI GPU.  The Mini is about 85% as powerful according to Geekbench, and if it dies I will not be out more than a few hundred bucks.
    I will be migrating all my OpenCL code to FreeBSD as well, because replacing a power supply or motherboard in a generic DIY PC is only a hundred or two dollars at the most.
