Dell Networking OpenFlow Hybrid enables the OpenFlow 1.0 Controller to add flows to different tables by making use of the most significant byte in the command field in the OFPT_FLOW_MOD message. If this byte is 0, the flow is added to the default table configured by the administrator. If the byte is not zero, the flow is added to the flow table specified in Table 48-2. The following table identifiers are mapped to the listed hardware tables. The table identifiers are not contiguous because some identifiers are reserved for future enhancements. The supported hardware table IDs, sizes, and descriptions are accessible through the switch user interface. Table 48-2. Flow Table Identifiers ID 0 1-3 4 5-23 24 25 26-31 32-255 Usage Description User-Configured table. This table ID in the OFPT_FLOW_MOD messages indicates that the rule should be added to the default table configured by the administrator. The standard OpenFlow 1.0 controllers always send 0 to the switch. Table 0 is not reported in the OFPST_TABLE message. Reserved Unused. Source MAC VLAN This table is in the VLAN Field Processor. Assignment Reserved Unused. OpenFlow 1.0 Rule IFP table containing OpenFlow 1.0 rules. Table MAC Forwarding IFP table containing multicast and unicast DA- Table MAC-based forwarding rules. Reserved Unused Unsupported The enhanced OpenFlow 1.0 protocol only supports table IDs 0 to 31. When using multiple hardware tables, it is possible to set up the hardware so that, for example, the MAC Forwarding Table and OpenFlow 1.0 Rule Table match the same packet. If the packet matches multiple slices in the IFP, the hardware performs all non-conflicting actions on the packet. For example, the OpenFlow 1.0 Rule Table may set the packet priority and the MAC Forwarding Table may direct the packet to a specific output port. OpenFlow 1649
