Assign more than one Tagged VLAN on a Switch Port

  • 1.  Assign more than one Tagged VLAN on a Switch Port

    Posted Nov 21, 2016 12:50 PM

    Hi all,

     

    I was just running in a problem, but so far I'm not sure if it is a bug in ClearPass, a configuration error or a limitation.

     

    What I try to achieve:

    I have an HPE AP which is configured for local bridging. So so static portconfig looks like: VL7 (untagged / management), VL 10-12 (tagged /SSID traffic)

     

    Now I want to assign all VLANs dynamically. So on Clearpass I created one Enforcement Profile per VLAN and bound them on my Enforcement Policy. After successfully authenticating my AP the switchport only gets two VLAN IDs assigned: VL7 untagged and VL10 tagged. The other two VLANs are missing.

    In the AccessTracker output I can see that only the two VLANs are forwarded to the switch.

     

    As I read the RFC on the FreeRadius page (http://wiki.freeradius.org/vendor/HP#procurve-port-authentication-special-features_dynamic-vlan-assignment_rfc-4675-multiple-tagged-untagged-vlan-assignment) the egress-VLANID attribut can assigned more than one time.

    "Times used = 1-*"

     

    Can anyone help me on this beahvior?

     

    thanks i advance folks!

    Not sure how you configured it, however when I try, I see the native VLAN and the tagged vlans assigned:

    And this is how my response shows in Access Tracker:2016-11-22 16_40_03-ClearPass Policy Manager - Aruba Networks.png

     

    What I did do, and might be a difference is that I have a single enforcement profile for the tagged ports, HP-Tagged-VLANs with the two VLANs in my lab inside. So two profiles in total.
