OpenFlow 1703
Although the OpenFlow IFP slices are lower priority than IFP slices used by
other Dell EMC Networking OpenFlow Hybrid components, the IFP itself is
positioned in the ingress pipeline after the forwarding database and the
routing tables. This means that IFP rules inserted by the OpenFlow feature
can affect switching and routing decisions.
VFP-based flows also may affect switching decisions and alter switching
protocols behavior by changing MAC addresses or/and VLAN IDs.
To avoid interfering with non-OpenFlow traffic, the rules should be qualified
with a VLAN ID reserved for the OpenFlow traffic. The Dell EMC
Networking OpenFlow Hybrid switch does not enforce any specific VLAN
IDs and also accepts wildcard VLAN IDs, so it is up to the OpenFlow
Controller to configure the switch correctly.
Refer to "Limitations, Restrictions, and Assumptions" on page 1739 for the
list of known interferences.
