Three Devices with Same MAC

I have three new SiriusXM devices that were giving me trouble a couple weeks ago. Turns out the root of the problem is that all three have the same MAC address. Amazing, but true. 76c2.5e30.1599.
I have a feeling I've given their engineering/manufacturing staff a big headache by discovering this, as they likely have a warehouse full of these things, all with the same MAC. Not my problem, but it would be fun to watch them discover what's going on. haha
But I digress...I don't think they have a solution yet, but I'd like to use the devices anyway, if possible. They are Internet-based XMSirius radios. They all worked when I connected them to the same switch, but the log was getting flushed several times a day with MAC flapping errors every few seconds. We tried separate vlans, but that doesn't work.
Any ideas on how to do something that we shouldn't need to do? :)

Hi John,
Is your question how to do away with the mac flap notifications. The switch is giving you its best possible help by telling you that there is a problem. But if you still want to get rid of it, you may try the following
(config)#no mac address-table notification mac-move
But again as a best practice i don't recommed to continue use these devices since it can some time cause issues in your network, since it keeps the cpu busy.
Hope this helps and rate my post if it is found to be useful.
Thanks,
Madhu.

Log file shows all devices with same MAC on EA6500

Just thought it was rather odd. I'm running firmware version 1.1.28.14856 on EA6500 series.
Thanks

The 6500 has numerous issues that is one of them, cisco knows of the issues but really has done nothing to fix them. I would stay far far away from the 6500 it really is broke right out of the box. If you search the forums here and other reviews on the web of the 6500 it's not pretty. The router was rushed to market without the propper testing and cisco decided to make you the customer test it for them. Good Luck with the 6500. And if the moderators in here dont like me telling the truth than simply delete my account here dont matter none to me. Cisco knows im right and so do many others.

HT201272 How can I recover a purchased app on one itouch (which has since died) and put it on my new itouch device if I haven't syncronised my old device with my mac/itunes account before it died?

It is easy to download items you have purchased from iTunes again; this article will walk you through it: http://support.apple.com/kb/HT2519
You want the "Apps on iOS" section.

Two Switches with same MAC+Priority running STP

Hi
what will happen if two switch with same MAC-ADDRESS and same STP priority will run STP , how will elect to the root bridge ???? how the STP process will handle this situation?
thanx

Well, first off, no two switches (or switchports) will have the same MAC (if they do, you're buying switches from the wrong, very bad place).
Every port of the switch will have (at least) one MAC of it's own.
Given the same priority for all switches/bridges on the LAN, the lowest switch/bridge MAC on the LAN will win as the root.
VLANS take on the MAC of the administrative interface ("CPU"): i.e., xxxx.xxxx.5000, the first port (i.e., fa0/1) is xxxx.xxxx.5001, the second (fa0/2) is xxx.xxxx.5002, and so on
If you do a "show interface", the MAC / bia is displayed in the second line.
Good Luck
Scott

EA6500 has numerous "network devices" with no MAC

I have noticed from time to time I get many (15-20) "network devices" in the Device List with no MAC address. I notice this mainly when managing Parental Controls. I go and clean up the Device List and days later they reappear.
Another interesting thing is that the computer I am writing this with (through the router) does not show up in the Device List and I have an IP address from the router.
I have the latest firmware 1.1.28.146856.
Does anyone else see this on their EA6500?

There are a lot of people who reported similar or related cases that you have right now. From what I have read, they reset their routers back to factory settings. There is one who got to a work around by adding all of his devices to the DHCP Reservation List and the router is working fine after that.

How could I sync an Android device with a Mac mini?

There does not seem to be any obvious way to sync contacts, or, indeed, much of anything. 'Accounts & Sync', in 'Settings' on the device doesn't acknolwdge that the Mac exists by direct USB connection, Bluetooth, or 802.11 wireless. The device doesn't show in the Finder when connected by USB or 802.11 wireless. (It does _charge_ when connected by USB, and it does show a network connection via 802.11 and its IP shows up on the network, it just won't connect to sync anything.) It's a T-Mobile device; T-Mobile doesn't seem to have any tools to make the connection, or at least I can't find any, and there aren't any apps in the App Store which seem able to do this, or again I can't find any. It's trivial to connect an iOS device; surely _someone_ has a way to connect an Android. Surely?

Help. Created new account with same .mac acct. Now all old questions gone.

Can someone at apple help me get my questions back into my account - I had to recreate it and now all my old posts are gone. Can they merge it back in? I recreated the account during the outage with my same .mac email.

I don't think that's possible... But who am I to say.
Try this: Go to this page but don't fill out the form. Instead, click on the "Forget your Apple ID?" link and fill out the form on the next page with the relevant information. It should be able to give you any Apple IDs you have set up in the past.
Hopefully you'll find that, under the .Mac address you're using, you actually had a separate +Apple ID+ that you can use to log into your previous Discussions account. (Note that your Apple ID is not the same thing as your forum alias and is not necessarily your email address.)

Use multiple Macs with same .Mac account to edit different sites

Last year our school purchased a .Mac account to host our school website. All of the teachers had been using the same .Mac account and using iWeb to publish their own sites. Because all the sites had different names, there were no publishing problems. That changed with iWeb 2. We experimented with the new iWeb 2 on a couple workstations and discovered that publishing to the same .Mac account on different Macs resulted in sites being overwritten by the computer that was published the most recently. What's confusing to me is the that sites were being overwritten even though the sites had different names. In other words, teacher "Jones" publishes their web named "jones" to .Mac. Teacher "Smith" then publishes their web named "smith". The result... the Jones web gets deleted and overwritten by Smith. In iWeb 1x, all the sites had their own named folders organized nice and neatly, now, no matter what we do, we still get the same overwritting issue. I can understand this happening if the sites all had the same name, but this is not the case.
This had been a great way for our teachers to easily publish their own pages, unfortunately they won't be able to take advantage of the new features in iWeb 2, if this isssue isn't resolved. Any help would be very much appreciated.

You've got a mess on your hands with only one iDisk being used and dozens of versions of the Domain.sites2 (made by iWeb) in use.
If all used the same version of the Domain.sites2 package things would work. That would mean sharing that same file each time anyone edited it between all users.
You could do that but eventually someone will make a change and fail to move to all users and the Site could get messed up at publishing.
If all of the teachers used the same machine and user account they could also upload to one iDisk.
Last would be to publish to folder and upload using the Finder for each user. Those pages would not include some .Mac specific features.

Set up family on several devices with same apple id

I have successfully started Family from my iphone and got my kids and wife connected. But when trying to add my ipad with same id as I use on my iphone I cannot succeed. It states that an account can only be connected to one family at a time. How is the procedure for this?

I could have solved it by inviting myself.

Cannot facetime or message with three devices on same Apple ID.

I have the I phone. My son has a I pod touch. We just purchased a I pod touch for my wife. My son and I are using the same ID and have not experienced any trouble with face time or sending messages. Now that my wife is on our account the messages go to both I pods from my phone and the face time does not work. Do we need to have separate accounts, if so how do we share the app's that we have purchased?

Each iPod should have its own unique email address that is associated with the same Apple ID you are already using. On each device head to Settings -> FaceTime and click Add Another Email.

EA6300 5g Problems and Devices with no MAC

Problem 1
I have been on the phone with Support about 5g connection problems;
sometime it connects, sometimes it does not,
When I reboot the router in my device connects, after awhile it starts to degrade and drop.
Yes I have separate ssid, Yes I have been working with support,
So I had to go back to version 1.1.39
Problem 2
Devices where showing up, with MAC address as 00;000;00
Sorry to Say I settled for my Asus RT-AC66u in the meantime.
Chris

Hi! You mentioned about 1.1.39, is that your current firmware? Did you try to update the firmware to Ver.1.1.40 (build 153731) and experienced the same issue? Did you also try changing the channel settings on the 5Ghz network?

How do I stop my texts and pictures from going to other devices with same Apple ID

I share my Apple ID with my son on his Ipad and I phone. how do I stop my photos and messages from automatically going to his devices.

It should be iMessages which are going from device to device, you can turn this off in recipient device. The same sort of thing for Photos, however on your phone/ipad you can turn off 'Photo Stream" which will stop the sending to other devices. You can do this under Settings>Photos & Camera.
Regards,
Steve

Can u sync three devices with two different apple ids my husband has a different Apple ID than I do?

I'm trying to sync my iphone 4 with my husbands iphone 4 and to my iPad Minni my iphone and iPad have the same Apple ID is there any way to synce his iphone to my devices?

I have no clue what you're talking about. Perhaps you can rephrase with correct spelling and real sentences that include initial caps and periods and other grammatical niceties.

IOS 8 double tap allows other device with same Apple login to see who other is messaging

I have two iPhones with the same AppleID account. The iMessaging for each device is set to only send or receive message and FaceTime from the phone number for each device to keep them separate. If device A is in a text message and the home button on device B is double tapped a notification will be visible to show device A is in a text message. Device B can then tap this notification and the person being text in Device A becomes available and a new message to that person is then opened. Not acceptable. I have tried to unlink the two devices in any way I now how. No luck. The screenshot below is what Device B sees if Device A is composing a message.

That's just the way it works, since you're using the same Apple ID on both. If you have a problem with that, go to http://apple.com/feedback/iphone.html.

Trouble using facetime on another device with same apple id

Hi
I am having trouble using facetime with my wife. I have an iPad 2 and she has an IPhone 4S. When we try to facetime, we are able to connect for a few seconds and then it drops off. We are then unable to reconnect. We both have the same apple Id and e-mail address although I am trying to contact her via her mobile number. Any suggestions would be grateful received.
