Capabilities supported by the MAC-IP flow table

The controller must include the required match fields and actions and can include the optional match fields and actions in the flow entries deployed to the MAC-IP flow table. If the controller does not include the optional match fields and actions in the flow entries, the switch adds them to the flow entries by default.

The Layer 2 flow entries are implemented by using MAC address tables. Table 3 describes the capabilities supported by Layer 2 flow entries.

Table 3: Capabilities supported by Layer 2 flow entries

Support items	Capabilities
Required match fields	The MAC-IP flow table must support the following match fields: VLAN ID. Unicast destination MAC address.
Optional match fields	N/A
Required actions	Specify the output port.
Optional actions	The MAC-IP flow table can optionally support the following instructions: Goto-Table—When the switch has multiple tables, the switch adds this instruction by default if the controller does not deploy it. Write-Metadata—When the switch has multiple tables, the switch adds this instruction by default if the controller does not deploy it.

The Layer 3 flow entries are implemented by using routing tables. Table 3 describes the capabilities supported by Layer 3 flow entries.

Table 4: Capabilities supported by Layer 3 flow entries

Support items	Capabilities
Required match fields	The MAC-IP flow table must support the following match fields: VLAN ID. Unicast destination MAC address. The destination MAC address must be the MAC address of the VLAN interface for the VLAN that is matched. Unicast destination IP address.
Optional match fields	N/A
Required actions	Specify the output port.
Optional actions	The MAC-IP flow table can optionally support the following actions: Modify source MAC address—The switch modifies the source MAC address to the MAC address of the virtual interface of the VLAN to which the output port belongs. Decrement TTL by one. Goto-Table—When the switch has multiple tables, the switch adds this instruction by default if the controller does not deploy it. Write-Metadata—When the switch has multiple tables, the switch adds this instruction by default if the controller does not deploy it.
