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", },
],
