2.1 Embedded Management (CLI/GUI)
There is a CLI provided by the DNOS-OF platform that is accessible from the serial port, telnet, and SSH.
There is currently no other management access. The CLI reference is included in an appendix at the end
of this document.
2.2 Supported Hardware
The DNOS-OF firmware is supported on the following N-Series platforms as of release 1.0:
- 3024
- 3024P
- 3048
- 3048P
The current plan is for support of all N-Series hardware in following releases.
2.3 Limitations and Product Constraints
 Dell Networking N-Series switches with the DNOS-OF firmware installed are pure OpenFlow only
switches. No legacy functions are available
 Only 1 SDN agent is supported per physical switch, no hybrid mode, and a CLI for a user interface.
 Only a single OpenFlow instance is supported, which includes all physical ports.
 The OpenFlow 1.3.4 spec is the only initial mode of compatibility supported, there is no backwards
compatibility with prior versions of the OpenFlow spec.
 DNOS-OF is quallified with the Ryu controller. This is in alignment with DNOS-9.x and their OpenFlow /
SDN mode release compatibility and testing.
 All OpenFlow 1.3.4 commands that are listed as “mandatory” in the spec are supported except for those
having to do with hybrid mode. Some OpenFlow 1.3.4 commands that are “optional” but that enhance the
product serviceability and value are supported as well.
 Stacking of DNOS-OF OpenFlow switches using standard Higig protocol is not supported.
 Basic SSH is initially provided in 1.0, with enhanced encryption and TLS in following releases.
 Packet buffering is not supported.
 Except for minimal system internal logging and output to the serial console, only remote logging being
supported so as not to impact the existing code.
