Hi, how can change the mac-address in ephone? My problem is that, I can not change a mac-address in ephone because CME say that the ephone had also mac-address associated.
Do not connect the new phone set to the CME before you had modified the mac-address of the ephone-dn.
Otherwise, you will have the error as you modify the mac-address in the system.
I've had this problem before - if you can put up with a reboot it's better to modify your config using a text editor then tftp it to routers startup-config and reboot - it seems to be pretty flaky when modifying MAC addresses 'live' if the phones have registered, even if you remove the MAC from the ephone.
I hit this when needing to swap phones/models and keep same extension numbers.
Yes my problem is this, I have to do the same (modify start-confg, put it with tftp and then reboot) to change the mac address associated to a ephone.
But is not possible to reboot the CME everytime that I change phone/model in my network! There are not a command to clear the list of phone registered (which you see with "sh ephone"), that it seem clear only when reboot?
Hello Peter ,
You can Only configure a New Mac Address when you first remove the Old One. This can be done by using the following command :
Router(conf)#no ephone mac-address xxx.xxx.xxx.xxx
This will remove the undesired Mac Address , Then you can add again the New One.
Sorry, you also have to
no mac-address 3037.a616.6280 = wrong
no mac-address 3037.A616.6280 = correct
then you can enter a new mac address.
you have to make sure all letters are capitalized.
Say if you have 2 phones on your network and one is broken , and you move one from one desk to the other you will need to do the following.
mac -address 1111.1111.1111
mac-address ( the one from ephone 17)
This is how I fixed the issue.
I already tried like what you said, all letters are capitalized. But still, the problem still happen. It said that
ephone slot is already registered with 70d4.ab74.0000.
Cannot change MAC address.
I already tried many ways to remove/replace the old mac-addresses with the new one. But it always said like the notification above. Do you have another way to solve this problem ?
Thanks for responding my question. I've already done that too, but the result still the same. When I executed the 'reset' command, it says
Jun 10 08:01:40.647:%IPPHONE-6-UNREGISTER_NORMAL: eogibe-7:AN270D4AB740000 IP:10.1.10.2 Socket:19 DeviceType:Phone has unregistered normally.
Jun 10 08:01:41.655:%IPPHONE-6REGISTER_NEW: ephone-7:AN270D4AB740000 IP:10.1.10.2 Socket:1 DeviceType:Phone has registered.
Besides that, I also already deleted the mac-address via CME, but when I added a new one, it only detected the previous mac-addresses (no other else).
Just execute the two commands in short sequence.
Note if you are trying to connect FXS ports in SCCP mode, you should not fight MAc, just leave as they are.
If you havn't fixed your issue as yet, please provide me an example of the issue. I would like to see the portion of the config you are trying to remove and how you are trying to remove the mac.
Right now, the phone has been run normally. I can't delete the mac-address previous day because the ip phone still plugged to the network (my mistake), that's why there is always a notification said that mac-address x.x.x.x is associated with ephonexx.
Remove the IP Phone from network, do not add new phone to netwok.
Delete ephone with old mac, no ephone xx ( Copy all the config to notepad for that ephone)
Add new phone to network if auto registration is enable that will register, apply all the copied config to to new ephone.
