set_vlan_vid(vlan) method is one of old API for OFPMatch and
OFPMatch(vlan_vid=vlan) is new API.
If you need to set masked VLAN ID,
I recommend you to use new API like as follows.
1) Packets with and without a VLAN tag
- Match class
ofproto_v1_3_parser.OFPMatch()
- Packet Matching
non-VLAN-tagged MATCH
VLAN-tagged(vlan_id=3) MATCH
VLAN-tagged(vlan_id=5) MATCH
2) Only packets without a VLAN tag
- Match class
ofproto_v1_3_parser.OFPMatch(vlan_vid=0x0000)
- Packet Matching
non-VLAN-tagged MATCH
VLAN-tagged(vlan_id=3) x
VLAN-tagged(vlan_id=5) x
3) Only packets with a VLAN tag regardless of its value
- Match class
ofproto_v1_3_parser.OFPMatch(vlan_vid=(0x1000, 0x1000))
- Packet Matching
non-VLAN-tagged x
VLAN-tagged(vlan_id=3) MATCH
VLAN-tagged(vlan_id=5) MATCH
4) Only packets with VLAN tag and VID equal
- Match class
ofproto_v1_3_parser.OFPMatch(vlan_vid=(0x1000 | 3))
- Packet Matching
non-VLAN-tagged x
VLAN-tagged(vlan_id=3) MATCH
VLAN-tagged(vlan_id=5) x
