Clearpass Dual Stack authentication ipv4,ipv6

    Hi,

    I have a question about Dual-Stack for authentication on ClearPass (v.6.9).
    When the clients have both ipv4 and ipv6 then it requires twice on each.
    It looks like 2 addresses on their computer.
    How can I configure to only one-time authentication?
    Please advice.

    What type of authentication?
    Is your ask about dual-stack on the ClearPass? Or Dual-Stacked clients?

    Most authentication is on L2, which means per client MAC. The client MAC is the same for IPv4 and all of its IPv6 IP addresses.

    Hi Herman,

    Captive portal for client authentication.
    Dual-stacked on clients but I'm not sure I'm correct or not.
    Currently, the clients browse to the ipv4  destination they will stick at captive portal however it also happens for ipv6 destination.

    Please advice.

    That is not what I expect for most switches. If you do a captive portal authentication, the client MAC address is authorized, not the Client IP.

    What is your setup with the captive portal? Switch? AP? Workflow?

    Or open a support case to have TAC look at it. It is not expected to have reauthentication per client IP (IPv4 and separate for IPv6), as the network infrastructure in most cases is unaware of the higher-level protocols above L2.
