OpenFlow 1.0 Rule Table
The OpenFlow 1.0 rule table implements many of the OpenFlow match
criteria and actions defined in the OpenFlow 1.0 standard.
The table is implemented in the Ingress Field Processor using slices
configured in the intra-slice double-wide mode. This means that the number
of rules in each IFP slice is divided in half to provide the necessary rule width.
The following sections describe the match criteria and actions supported by
the OpenFlow 1.0 table.
• OpenFlow 1.0 Match Criteria
Table 48-3 defines the OpenFlow 1.0 match criteria supported by Dell
EMC Networking OpenFlow Hybrid. The fields in the table correspond to
the fields defined in Table 3 in the OpenFlow 1.0 Switch Specification.
In summary, the Dell EMC Networking OpenFlow Hybrid switch
supports matching on all fields specified in the OpenFlow 1.0 standard
except the IP address fields in ARP frames and the ARP op-code.
If the switch is configured to operate as a router, then for IPv4 packets, the
hardware matches the packet fields only if the packet can be forwarded by
the hardware. Packets with IP header errors and packets with options in the
IP header are sent to the switch protocol stack and cannot be intercepted
by the OpenFlow controller.
If the switch is not a router and is only performing layer-2 switching, then
it ignores IPv4 header errors and applies the match rules to all IPv4
packets.
All fields in this table can be wild-carded.
