[Kea-users] Class selection with Option 82

[Andre Roberge]

Hi, 
I'm having some issues with classifying my client classes with the vlan out of option 82. I'm getting the interface with my vlan using Juniper Network. Is there a way not to get the interface appended to the vlan from a Juniper ?

Here is my client class selection which is working: "client-classes": [        // vlan45        {            "name": "vlan45",            "test": "substring(option[82].option[1].hex, 12,2) == 0x3435",        },
    ],
