NCS wired MAC trace incorrectly puts MAC at uplink ports

Greetings,
I generally love the Cisco Prime NCS functionality which allows one to quickly trace a MAC address to a switch and port.  However, I'm having trouble with some MACs appearing at the uplink port of a closet switch rather than it's real access port on a different.  While it is true that this PC's MAC is in the CAM for that closet uplink port, it's there with hundreds of others.  It is also in the CAM for the port it is actually connected to, and in that case it's the ONLY MAC for that port, as expected.   Both switches are functioning within NCS, and in fact if I drill down into the switch it is connected to, the client detail shows this MAC connected to the proper port.  It's just the search trace that "incorrectly" shows it out at some uplink.   In fact, it moves around to different closet uplinks (per the MAC search history results).  It doesn't only happen with this MAC, either.   I kind of sold the customer on this functionality and it's a little embarrassing.
1. Has anyone seen it and knows of a way to get it to show correctly and/or prevent this problem?
2. What criteria does NCS use to determine where to place the item when the MAC appears in multiple places?  I would think it would at least pick a port that does not have other MAC addresses on it first, under the assumption that ports with multiple MACs are uplinks (I realize that there are cases where it COULD be on a multiple MAC port, such as an uplink to an unmonitored switch...not the case here).   I can tell you that in the cases I've noticed, the uplinks are not 802.1q, just access ports.
Thanks!

Had the same issue here.  Here is the best solution I have found so far:
Hotspot + Pepwave Max On-The-Go (w/ Load Balancing) + Airport Extreme
I have a VZW MiFi, but I believe this set-up will work with other hotspot devices.  I actually have 2 MiFi Hotspots with a monthly allowance of 20G each.  They are plugged directly into the Pepwave router (aka, tethered).  (Note:  you have to have the right cable to do this.  The one that came with my Hotspot was only for charging.)  If, for some reason, you cannot tether with your Hotspot device, you want a router that offers WiFi as WAN.  The Pepwave will do this.  The Pepwave is connected to my Airport Extreme via ethernet cable.  I have the WiFi on the MiFis and the Pepwave turned off.  So the only visible network is my Airport Extreme.  The Pepwave is essentially just functioning as a modem.
I used to have a Cradlepoint, but I did not find it very user friendly--too complex for home use.  The Pepwave Max OTG is awesome.  I got the one with Load Balancing so it allows you to connect up to 4 cellular devices.  If you only need the one Hotspot, you can just get the cheaper Pepwave Max OTG.  The Pepwave allows me to run off one of the MiFis until I hit my 20G/month allowance, then it automatically switches to the other one.  That way I never max-out on my monthly data allowance.  Additionally, it gives you a real-time, hourly, daily and monthly running tally on data usage.
The guys at the 3Gstore are excellent and can help you figure out the best solution for your situation.

  • SCCM 2012 Losing Wired Mac Address of Laptops

    When attempting to re-image a laptop I have found that SCCM replaced
    the wired MAC address in properties with the wireless MAC. This is only an issue when I go to image as it will not PXE, I get a no boot file received message.
    I have been deleting the laptops from SCCM completely and then re-importing them using the wired MAC.
    After re-adding the laptop with the wired MAC it is still holding a record of the last PXE Deployment (once deleted the
    system will PXE boot fine). 
    Is there a way to have SCCM actively hold both MAC addresses?

    I'm in the same boat as JLCARON401. Laptop devices in SCCM seem to forget the MAC address of the wired interface.
    Tim, they show up in the Hardware History section of Resource Explorer, but not in the current view. You can see the device listed, but the MAC field is empty.
    I just put this together to grab data from the database directly to confirm that the data exists.
    SELECT DISTINCT
    MACAddress00
    FROM
    [CM_PEN].[dbo].[Netcard_HIST] netcard
    INNER JOIN
    [CM_PEN].[dbo].[Computer_System_DATA] computer
    ON
    netcard.MachineID = computer.MachineID
    WHERE
    computer.Name00 like 'SMS-LIB-MD%'
    AND
    netcard.MACAddress00 IS NOT NULL
    AND
    netcard.AdapterType00 like '%802.3%'
    Not sure where to go with this next. I'm looking into it because we're having problems with laptops that charge in a cart are missing updates. I've rigged up a cart with power and a switch so each laptop can be powered up (WOL) during the night to have all
    the outstanding deployments installed.

  • Wireless and wired mac pro isue

    I recently bought a mac book air, Im trying to use my mac_pro's optical drive, but my mac pro
    is not wireless, it is wired conected to a linksys router to get the internet, when Im trying to make virtual conection with the remote disk option, nothing appear on the list...
    A step of the process on the guide says "Make sure your mac book air an the other computer and on the same wireless network", does it means that I can't use my wired mac pro 's optical drive to share?
    please somebody help me...

    I'm going to disagree with Kappy - it does work with wired computers. Instructions for Optical Drive Sharing are on Page 15 of the MacBook Air Users guide. You will need to install the Optical Drive Sharing software package on the host Mac if it is running Tiger (10.4.10 required) that's on Disc 1 of the MacBook Air System Discs.

  • AirportExtremeN sharing among wireless and wired Macs how?

    I've an AirportExtremeN base station with Airdisk that works fine wirelessly with my MacBookPro (Tiger) and a desktop PC running XP, as well as an eMac (Panther) and a Mini(Tiger) that are wired to the same AirportExtremeN base station via ethernet. All 4 machines print to the USB printer and share a DSL internet connection fine too.
    I cannot figure out
    (1) how to share the AirDisk with the wired machines, or
    (2) how to mount the wired Mac's on the MacBookPro.
    I've got the latest software versions and the AirportExtremeN firmware updated.
    Advice please

    1) On the wired machine(s), use the Go menu in the Finder to connect to your "server." It is the same IP address as your AEBS, so usually 10.0.1.1.
    2) not quite sure what you mean, but if I'm guessing correctly, it's the same procedure as file sharing over any network and is not specific to your AEBS or Airdisk. Use the same Go --> Server menu to log onto and mount any wired Mac that has file sharing turned on.

  • A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port.  WHen we plugged it into the port on the keyboard, the device works. Why?

    A barcode scanner that was connected directly to the Mac's USB port stopped working as the "USB had too much power drawn", even though it has worked for over a year in that port.  When we plugged it into the port on the keyboard, the device works. Why?  Obviously the device is operational.  Could the USB port have burned out from having too much power drawn?  If so, is it reparable?

    It can't draw "too much" power, it can only draw as much as the USB port is able to provide and no more. IIRC, the keyboard port has a lower power output than the iMac's port.
    That being said, yea, it's possible that the port has failed and it can be replaced or if another port works you can use that one. Although if it is still under warranty or covered by Apple Care, then I would take it to an Apple Store or service provider to get the port repaired.

    Thank you for your reply. So, you mean that I can do this via SNMP? What are the OIDs or the MIB? Is there any available documentation on how to do that?

  • Mac G5 firewire porting problem.

    Hello,
    I am having a problem with my G5 Powermac firewire porting.
    Everything was working fine until we physically moved the mac and peripherals to another office. Now the Firewire drive is not recognized and the Sony DSR45 cannot connect.
    Whats really wierd is if I have the Sony DSR45 turned on and I go into the view menu in FCP Studio 6, I can checkmark the "all frames" and it won't change anything. If I turn the deck off, I can change the setting and it will stay changed.
    I have tried shutting down the Mac, turning off the DSR45, wait ten minutes, turn on the DSR45, turn on the Mac, the Firewire drive is not recognized and neither is the DSR45.
    How do I get the Mac to re-port the firewire ports?
    I am using the 800 firewire connection for the Firewire drive.
    This all worked fine before moving the system to another office.
    Any help is greatly appreciated.
    Ymir

    Try resetting the PRAM. This resets the presence of all hardware devices. Start up holding the keys: command, option, P, R. Hold these keys for 3-chimes and release. Hope this helps.

  • Is there ANY way to disable internet for specific wired MACs?

    I have been looking for a way to restrict specific MAC addresses from routing to the internet with my AEBS. The Access tab is labeled that it allows internet access for only the MACs in the list which is incorrect, it restricts connections to the AEBS entirely (not just to the internet).

    That is correct - Access Control cannot be used to limit wireless clients from accessing just the internet. Access Control also has no influence at all on restricting access by wired clients - it only influences connections by wireless clients.
    I assume the purpose of this is to find a way for a parent to limit internet access from one of their child's computers? If so, you should instead use software on the Mac itself, like the MacOS 10.4 "parental controls" feature.

  • Trying to use ATV wirelessly with a wired Mac Pro

    I have a new Mac Pro that is connected via ethernet to an Airport Extreme via a 16 place switch. The AX controls the IP addressing. I also just purchased an ATV to hook up to my HDTV. I attached it and booted up the ATV, it went through the start-up process and I was able to stream movie previews easily. The problem is that it is not seen by the Mac Pro. The ATV has the latest update as does the Mac Pro. Failure of iTunes to see the ATV or vise versa seems to be a consistent problem.
    To complicate the problem, I have an Airport Express in another part of the house to stream audio, a Belkin wireless bridge as a print server to 2 ethernet printers, and another Belkin wireless bridge to the same Sony TV for updates.
    I am at a total loss as to why they cannot see each other. Is the fact that the Mac Pro wired to the network and the ATV wireless a problem? Everything else seems to work from wired to wireless. Any help is appreciated!

    Finally got it to show up in the devices bar last night. It would not show up at all unless I have the ATV on the sync screen. Just sitting there by the TV was not good enough for the two to recognize each other. I found this out by accident while sitting on the couch fumbling with my laptop and playing with the menus. While changing settings and menus, the ATV appeared suddenly when I went back to the sync screen. When I went to the desktop with the ATV still on the sync screen, it appeared. Now everything works well. I just wish that the internal storage drive was larger since my iTunes library is >132GB by itself. That doesn't give much extra room!! Thanks all.

  • Help:  hard wiring MAC MIni to Linksys wrt55ag wirelss router

    I hope someone can help me with this, it is driving me nuts. I have a mac mini that is hard wired to a Linksys wrt55ag wireless a and g router. To make thinks worse. I have a linksys voice over IP box.
    I can get it to work but i keep losing the connect and the phone keeps cutting in and out. It seems that the mini, even though hardwired to the wireless router, loses its conenction to the router. It is unable to find it.
    I am close to scaping the whole thing, has anyone heard of this problem? is their a solution?
    I set up using dhcp in the mini mac and ppoe in the router. Have both the mini mac and the woip router hard wired to Linksys wrt55ag.

    Since you are using PPPoE, I assume that you have the Linksys router connected, via Ethernet, to a DSL modem...correct?
    If so, if you connect the Mini directly to the modem, is the connection still unstable?

  • Wired Mac on Airport Extreme slowing down Wireless network?

    I have an Airport Extreme 802.11n and a MacBook Pro 15" (unibody). I recently added a MacMini Core 2 duo as an iTunes server, and since it didn't have 802.11n (it's an older one), I shut off the WiFi and ethernet cable'd it to my Airport Extreme. It works great; I can see the Mini in Shared devices from the MacBook Pro, share the screen, and my Apple TV syncs beautifully as well.
    Then today I noticed that the internet connection on my laptop was really slow. After some chasing I realized that the same speed tests from http://www.speakeasy.net/speedtest/ ran on the ethernet-Mini vs the WiFi-MacBook Pro were radically different. At any given time, the speed on the MacBook Pro was as low as 25% the speed on the Mini… sometimes even worse!
    I discovered that if I shut down the Mini, the MacBook Pro speed increases. Not to the same point as the Mini, but I can attribute some loss to just being on WiFi and only getting about 60% signal strength (according to iStumbler -- even though the mac WiFi signal strength shows full bars… anyway). But in the past (before the Mini was added) I've run those speedtests and seen results like I'm seeing now only on the Mini.
    So why would this tethered Mac be causing such a slowdown?
    I'm about to upgrade to the new Time Capsule with separate 802.11 b/g and n antennas but would like to understand this problem before I make that upgrade. Something else feels wrong to me.
    btw I did recently upgrade to the 7.4.1 firmware (at the same time I did the Mini addition… poor science, I know), and so I tried reverting it back to 7.3.2 to see if that made any difference, and it did not.

    So I started poking around a bit more this morning, and ended up doing a slew of tests. A LOT of tests. I tested two different portables and the Mini, tested with the Mini off and on, and tested with Safari 3 or 4 (depending on what was on each system) and Firefox 3. I then tested the portable plugged directly into the wire.
    I ran each test three times and averaged them.
    There are some very interesting results.
    Tests with Mini on vs. Min off makes a negligible difference on average on Safari. However Firefox performance consistently went down with the Mini off.
    But here's the big shocker – performance of any wired computer was between three and TEN (!!!!) times that of the wireless! This is unbelievable.
    Worth noting I was sure to disable all other wifi devices on the network, even the other portable, when performing the tests. Apple TV and iPhones were all powered down during these tests.
    All my test results are visible here on iWork.com here: http://bit.ly/KYGTj (I think anyone can log in using an apple ID, if not then email me or post your email address here and I'll add you to the list)

  • How do I connect my aiport express to my wired mac mini?

    Hi. I have a Airport Express Base Station and I would like to connect it to my Mac Mini via ethernet cord. My Mac Mini is wired only however, no airport installed. I do however have a wireless router.
    Mac Mini   Mac OS X (10.4.8)  

    Macman07, Welcome to the discussion area!
    If your wireless router is not an Apple AirPort Extreme base station (AEBS) or AirPort Express (AX), the chances of you succeeding are nearly zero.
    The AX's Ethernet port is ONLY active when the AX wirelessly joins a network using WDS. Very, very, very few non-Apple devices support Apple's WDS.

  • Ping a wired Mac to stop Airport dropout

    All my wireless Macs at home are experiencing the horrid intermittent Airport dropouts that seem to be caused by a recent Apple update.
    I've found that pinging a wired computer on the network magically restores the Airport connection on the wireless ones... for a little while.
    The only reliable way I've been able to keep the connection active is:
    1. open two terminal windows and in one type ping -i 2 nameofwiredmachine.local. This will ping that computer every two seconds.
    2. In the second window type ping -i 3 nameofwiredmachine.local. Wait until a half-second or so after the first window responds with a successful ping before hitting enter.
    Between these two windows, you should be able to keep your connection active as long as your Airport card deigns to acknowledge that there is, in fact, a signal being received.
    If your Airport card goes into signal denial, then you're stuck waiting until it comes back. Note that one window does not reliably keep your connection active. The dropout will frequently happen in-between pings and stall a single ping process.
    Every once in a while, a stall will happen while both ping windows are waiting for a response. In that case, you can focus on one of the ping windows, type ctrl-c, then hit the up key and press enter. That ping process will kick-start the other one.
    your pal,
    - kevin

    Turn on the wireless card in the older Mac if it has one. However, it should not make any difference on a local network. You should be able to communicate even though one is wireless. So, I would look at your Sharing setup.

  • Block Wired MAC addresses?

    WRT54g Version 5.0
    Firmware 1.02.8
    I have been able to figure out how to block Wireless MAC addresses, and that has been VERY helpful.
    ( Wireless Tab -> Wireless MAC filter -> Permit Only -> and so on.... )
    But I am cannot find out how to block certain wired based MAC addresses.  Is this possible?
    Solved!
    Go to Solution.

    Yes. With access restrictions.
    Of course, as MAC addresses are easily changed, cloned and detected on wireless connections (as MAC addresses are always transferred unencrypted) the wireless mac filter is useless for wireless security. On the wireless, use WPA2 Personal with AES and a strong passphrase. The wireless MAC filter won't make a difference in regard to your WPA2 protected wireless network.
    Same applies to wired devices and access restrictions. Of course, the difference with wired connections is that you have better control over you can plug into your router and who not...
