Hi,
Specifying "dl_vlan": 0 means you are going to match a VLAN-tagged packet
with VLAN ID=0, and you should first push a VLAN tag to a non-VLAN-tagged
packet before setting vlan_vid for it.
Since there's no way to specify an exact match of VLAN-untagged flows for
ofctl_rest at present, I suggest you lower the priority of the second flow
entry.
curl -X POST -d '{"dpid":"0000000000000001",
"priority":"32763","match":{"in_port":1},"actions":[{"type":"PUSH_VLAN","ethertype":33024},
{"type":"SET_FIELD","field":"vlan_vid","value":4102},{"type":"OUTPUT","port":2}]}'
