{ The controller cannot modify the table-miss flow entry through the Modify request. The
controller can only modify the table-miss flow entry through the Add request.
{ The controller can modify or delete the table-miss flow entry only through the strict version
of the Modify or Delete request. The controller cannot modify or remove the table-miss flow
entry through the non-strict version of the Modify or Delete request despite that the match
fields are wildcarded.
• Common flow entries
The controller cannot modify or remove all common flow entries through the non-strict version
of the Modify or Delete request despite that the match fields are wildcarded.
Appendix B MAC-IP flow table
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 descri
bes 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. If the controller includes this match field in
the flow entries, 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
