• Drop—Drop the packet.
• Controller—Send the packet to the controller.
• Normal—Forward the packet to the normal pipeline.
Dynamic aware
On an OpenFlow switch that supports MAC-IP flow tables, you can configure OpenFlow to support
querying and deleting dynamic MAC address flow entries.
The controller can query and delete dynamic MAC address flow entries by specifying a VLAN, a
MAC address, or the combination of a MAC address and a VLAN.
MAC-IP flow table cooperating with extensibility flow table
Metadata/mask
The MAC-IP flow table supports the Write Metadata instruction and the extensibility flow table
supports Metadata matching. The MAC-IP flow table can cooperate with the extensibility flow table to
perform the pipeline process of multiple tables by using Metadata.
Each metadata mask bit has a different meaning. The corresponding metadata bit being set
indicates that the metadata mask bit is matched. When the corresponding metadata bit is not set, the
metadata mask bit is wildcarded.
Table 7 Metadata mask meanings
Metadata mask bit Meaning Metadata
Bit 0
Destination MAC
address
• 1—Set. Matches the destination MAC address.
• 0—Not set. Does not match the destination MAC
address.
Bit 1 Source MAC address
• 1—Set. Matches the source MAC address.
• 0—Not set. Does not match the source MAC
address.
Bit 2
Destination IP
address
• 1—Set. Matches the destination IP address.
• 0—Not set. Does not match the destination IP
address.
Others Reserved Reserved.
Matching restrictions
When the output action in an extensibility flow table is not Normal, the following rules apply:
• The MAC-IP flow table does not take effect.
• All actions are executed according to the extensibility flow table.
When the output action in an extensibility flow table is Normal, the following rules apply:
• The output action is executed according to the MAC-IP flow table.
• The other actions are executed according to the extensibility flow table.
