    Hi Created,

     

    This guide below is how to set up DACL's and how to dynamically assign a vlan to a device connecting to the network.

    What you normally would do is trigger a 'Terminate Session', where the switch will do a new authentication for the user/device and you can then return the new role/DACL as part of your policy/enforcement.

    I'm not sure if ISE support DACL for Aruba switches, but you may fallback to user roles and return a local user role.

    Hi Herman,

    Yes i have configure DACL from ISE to ARUBA switches and its working perfectly but i need to do changes of the DACL and i havent figure out how to do that.(use vsa 92 standard by the way) if you need the config just let me do a session withb the cliente to do screenshot of ise and the config of the switch(the hardest part was to send the client ip address to ISE).

    With the COA 'Terminate Session' if you have the experience with Cisco ISE could you show me how that configuration of the terminate session goes, i havent got that part i still have doubts with that configuration.

    Saludos,

    You can initially deploy user role with policy and assign different user role having different policy based on your requirement using reauthentication CoA as below

    so i can add the:

    92

    NAC-Default-ACL

    and send that information on the reauthenticate for the Aruba siwtches rigth?

    i think i gettoting so what you do on the definition of the ISE is defines de VSA that im going to send the switch rigth?

    Yes we could send NAS-Filter-Rule via CoA.

    You have to enable this CLI for radius dyn authorization 

    radius dyn-authorization enable

    radius dyn-authorization client {<IPV4> | <IPV6> | <HOSTNAME>}

    [secret-key [plaintext <PASSKEY> | ciphertext] <PASSKEY>]]

    [time-window <WIDTH>] [replay-protection {enable|disable}]
