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 the 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 |
|
Bit 1 | Source MAC address |
|
Bit 2 | 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.
