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/mask instruction and the extensibility flow table
supports Metadata/mask matching. The MAC-IP flow table can cooperate with an extensibility flow
table to perform the pipeline process of multiple tables by using Metadata/mask.
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.
