    hi,

     

    we have an issue while we are trying to configure cppm with cisco voip on cisco port switch,

     

    we've created mac auth service, and did all configuration on port for mab and dot1x,

     

    once we plug the voip its authenticated and authorizde but after 2 minte it keeps try to reauthenticate and reauthorized again and again ,

     

    how to stop it

    thank you

    Config looks good. Most common issue is that the phone can not talk to the pbx so it will reboot to try again. Make sure it can route correctly on the vlan.

    Then you need to enable debug on the switch and see if it is getting the correct vlan. If it's getting the default then the void vlan is not in the switch Config or you're enforcement profile is incorrect. Post a screen shot of access tracker and each of the tabs

    Under the interface do the following:
    switchport voice vlan <VOICE VLAN>

    we've already added it,

    voip getting ip address, but from default access vlan,its not redirecting to enforcment vlan

    Hi , 

     

    I understand that you are only using cisco phone to mac auth with clear pass. You mention 802.1x ..Please elaborate .

     

    Can you share me the enforcement profile  which you did in clear Pass. I want to verify that if you are sending the correct attributes COA to the cisco switch ?

    i solved  it buddy,

    authorization command was missing, and you have to delete switchport voice also, in order to send ur vlan assignment :D
