What is necessary for collaboration PC+IP phone at the same time.
Thanks for your help.


Correct Answer by Nicholas Poole about 4 years 3 weeks ago

Multi domain means that one device is in the DATA domain and the other, the IP Phone is in the VOICE domain.  Is your ISE box sending the correct authorization to the IP Phone to be in the VOICE domain?


Without this working you will just have 2 devices contending within the same data domain whcih isnt what you want.

Good afternoon. Thanks for Your advice. The problem was the following: forgot to add the command

aaa authorization network default group radius

Now everything is working.

Fa0/2      001b.bafb.7c1c  mab      VOICE    Authz Success  0A32FF15000000B6500A0895

Fa0/2      001a.4b7b.0394  dot1x    DATA     Authz Success  0A32FF15000000C353ADA437

Thanks to all.

I would like to verify that in my case, I did not authorize the phone for the voice domain in an authorization rule as the root of this same problem I was facing.


To fix this, I created an authorization result that simply had the "voice domain permission" checked and used that in an authorization rule to authorize profiled IP-Phones. I did not use dynamic vlan assignment since we are in the very early stages and have the voice vlan already on the switchports.
