OpenFlow1.3 Spec describes watch_port/watch_group as follows.
/* Bucket for use in groups. */
struct ofp_bucket {
...
uint32_t watch_port; /* Port whose state affects whether this
bucket is live. Only required for fast
failover groups. */
uint32_t watch_group; /* Group whose state affects whether this
bucket is live. Only required for fast
failover groups. */
...
}
So, if the watch_port/watch_group is down, a bucket which includes
this port and/or group can NOT be a candidate for forwarding.

Currently, the curl command of ofctl_rest.py is not compatible with masked vlan
tags.
But now, we are making patches to support it.
Please wait for the patches release.

For your information, set_vlan_vid_masked() is one of old API for OFPMatch.
In new OFPMatch API, you can use it like as follows.
1) Packets with and without a VLAN tag
- Match class
match = dp.ofproto_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
match = dp.ofproto_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
match = dp.ofproto_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
match = dp.ofproto_parser.OFPMatch(vlan_vid=(0x1000 | 3))
- Packet Matching
non-VLAN-tagged x
VLAN-tagged(vlan_id=3) MATCH
VLAN-tagged(vlan_id=5) x
