+# Running ONOS with Mellanox Spectrum/Spectrum2 Switches
+
+## Spectrum and Fabric.p4
+The Spectrum architecture supports the fabric.p4 pipeline, but using the spectrum_model.p4 instead of the v1model.p4.
+The folder location p4c-out/fabric-mlnx/spectrum/default is where the P4 compiler artifacts should be placed for 
+ONOS to properly load and configure the pipeline for the Spectrum switch. 
+These files include:
+
+* cpu_port.txt:   defines the SDN port number to be used when sending a packet to the controller
+* p4info.txt:     the P4Runtime output file, in protobuf text format, when compiling fabric.p4
+* spectrum.bin:   The "binary blob" P4 compiler output, which contains all the data necessary to reconfigure the 
+  switch pipeline (P4 device config, as described in the P4Runtime specification)
+
+Since at this time the Mellanox P4 compiler backend is under active development and is not currently open sourced,
+please contact your Mellanox representative for access to the compiler and/or the compiler artifacts described above.
+
+For the latest details, please take a look at the wiki page instructions:
+https://wiki.onosproject.org/display/ONOS/Controlling+P4Runtime-enabled+Mellanox+Spectrum+switch+with+ONOS
