Matching restrictions
VLAN matching
Table 1 describes the VLAN matching restrictions when an OpenFlow instance is associated with VLANs.
Table 1 VLAN matching
VLAN Mask Matching packets
- -
All packets in the VLANs that are associated the
OpenFlow instance.
0 -
Packets without a VLAN tag. The PVID of the ingress port
must be associated the OpenFlow instance.
0 Value Unsupported.
Valid VLAN -/value Unsupported.
0x1000 -/value(except non-0x1000) Unsupported.
0x1000 0x1000
Packets with a VLAN tag. The VLAN ID of the VLAN tag
must be associated with the OpenFlow instance.
Valid VLAN |
0x1000
-/value
Matching packets by the combination of the VLAN ID
and VLAN mask. The VLANs obtained through the
combination of the VLAN ID and VLAN mask must be
associated with the OpenFlow instance.
Other Other Unsupported.
Protocol packet matching
If protocols are enabled, protocol packets (except LLDP frames) are processed by the corresponding
protocols instead of the OpenFlow protocol.
For more information about LLDP frame matching, see "
LLDP frame matching ."
Packet-out messages restrictions
Ingress port
If a Normal, Local, In Port, or Controller reserved port is used as the output port in a Packet-out message,
the ingress port must be a physical port or logical port.
Buffer ID co-existing with packet
If a Packet-out message contains both the packet and the buffer ID referencing the packet stored in the
switch, the switch only processes the buffered packet and ignores the packet in the message.
