force static vlan

  • 1.  force static vlan

    Posted Apr 19, 2021 12:58 PM
    Hello,
    I configured a SSID with WPA2 + AES and 802.1x security on my IAP505 Aruba Acess Points
    I have to use a external (don't manage by our team) radius server to authenticate my clients.
    The problem is this radius is used by the other company to affect laptops on several Vlans
    We don't have these vlans and just want to affect to a static one.

    Question: how to force this SSID on a static vlan (and ignore the answer of the radius server) ?
    Thanks

    Pierrick

    I believe that could be dome through server rules in the authentication server group. I have not used that since before AOS8 though.

    Therie is no "server group" notion with Aruba Instant 8.7

    Sorry, I missed that this is Instant. I have not set up RADIUS authentication in Instant. RADIUS is usually used in large companies and Instant in very small ones.
    What information is returned by the RADIUs server? If it is an Aruba user-role the IAP determines the VLAN.

    if a VLAN name is returned perhaps VLAM mapping could map that name to a VLAN id.

    IAP is enough for our 3 buildings (-;
    External Radius answer is a Vlan. But as I said before we don't have such Vlans
    I tried to map any of the answers with Tunnel-private-group-id not equals to 99999 to our Vlan.
    But it didn't work anymore ...

    What exactly does it return? There is no RADIUS attribute for VLAN Id. One generic way is to use filter-id.

    Some wired switched use a different group of IETF attributes. Here for our Cisco switches we return a VLAN name





    Your Aruba SE or VAR should be able to assist.

    The "Tunnel-private-group-id" response is given by the external Radius server. The other company use it for the vlan assignement.

    Do they supply a VLAN Name or ID? As previously stated, if a name perhaps you can use VLAN mapping.

    What might be worth a try is to set a static VLAN on the network SSID..

    Of course, this was the first thing I do. But the Radius Response is stronger (-;

    Sorry ,I have not used RADIUS servers with IAP.

    The only way I can think of is to set up your own RADIUS server (FreeRADIUS perhaps?), proxy the authentication to the corporate RADIUS servers but set the authorization to the desired VLAN ID.

    I'm thinking at proxy Radius Server as a final solution.
    It's too bad that IAP can't do this directly !

    Thanks a lot for your help

    You may try if the following will work with Dynamic VLAN assignment:
    Did not try myself, but it may work. It's checking that the VLAN ID is not 9999 (which is never the case as that VLAN number does not exist).

    I tried this too. Unfortunately, it didn't work.
    Maybe it's a bug from IAP 8.7.1.3. My Aruba Partner will open a ticket about this

    Cheers
