    Posted Mar 06, 2019 05:56 AM

    Hello,

     

    I have a problem with the clearpass when I send a Radius Coa to the switch. It always gives me the same error: 

    0000:00:25:52.77 RAD tRadiusR:DISCONNECT REQUEST id: 7 from 10.253.27.12
    DROPPED, Invalid packet authenticator.

    I have no problem in the validation user through 802.1x. It works well and in Clearpass validates, however when I send an RCoa the switch does not respond and makes a drop of the package.

    This is what I have configured in the switch:

     

    radius-server host 10.253.27.12 encrypted-key "encripted_key"
    radius-server host 10.253.27.12 dyn-authorization
    radius-server host 10.253.27.12 time-window 0

     

    SW(config)# sh radius

    Status and Counters - General RADIUS Information

    Deadtime (minutes) : 0
    Timeout (seconds) : 5
    Retransmit Attempts : 3
    Global Encryption Key :

    Source IPv6 Selection : Outgoing Interface

    Can you help me?

     

    TY

    check whether below setting configured properly

    • RFC server IP configuration and shared secret
    • Port 3799 is allowed
    • What type of Radius CoA template you are using?

    Hi,

     

    • RFC server IP configuration and shared secret --> Yes, i can do 802.1x.
    • Port 3799 is allowed--> Yes, i receive in switch radius coa
    • What type of Radius CoA template you are using? --> [ArubaOS - Terminate Session]
    • Another one--> Same NTP Server

    I try with differents templates for Radius_Coa and ever i receive same error --> Invalid Packet Authenticator.

    Looks like you want a Disconnect, not a CoA. Use the [ArubaOS Switching – Terminate Session] profile.

    If you’re trying to Disconnect the user, it’s a Disconnect, not a CoA. [ArubaOS Switching - Terminate Session] is the correct enforcement profile.
