{{Short description|Operating system for network equipment}}

'''DNOS''' or '''Dell Networking Operating System''' is a [[network operating system]] running on [[network switchesswitch|switches]] from [[Dell Networking]]. It is derived from either the [[Dell PowerConnect|PowerConnect]] OS (DNOS 6.x) or Force10 OS/[[FTOS]] (DNOS 9.x) and will be made available for the 10G and faster Dell Networking S-series switches, the Z-series 40G core switches and DNOS6 is available for the N-series switches.

==Two version families==

The DNOS [[network operating system]] family comes in a few main versions:

Line 9:

===DNOS6===

* DNOS 6.x: This is the operating system running on the Dell Networking N-series (campus) networking switches. It is the latest version of the 'PowerConnect' operating system, running on a Linux Kernel. It is available as upgrade for the PowerConnect 8100 series switches (which then become a [[Dell Networking#N4000: 10Gbit multi-layer switches|Dell Networking N40xx switch]]) and it also is installed on all DN N1000, N2000 and N3000 series switches. It has a full web-based GUI together with a full CLI ([[Command-line interface|command line interface]]) and the CLI will be very similar to the original PowerConnect CLI, though with a range of new features like PVSTP (per VLAN spanning tree), Policy Based Routing and [[MLAG]].

===DNOS9===

* DNOS 9.x: This is the operating system running on Dell Networking S- and Z- series switches and is a further development of the [[FTOS]] or Force10 Operating System. Standard DNOS 9.x (and FTOS) only offers a CLI and no GUI, although with the automation toolset it is possible to create your own webGUI on DNOS9 / FTOS switches. DNOS 9.x is running on [[NetBSD]].

* DNOS 9.x: TeUTg on [[NetBSD]].

Only the PowerConnect 8100 will be able to run on DNOS 6.x: all other PowerConnect ethernetEthernet switches will continue to run its own PowerConnect OS (on top of VxWorks) while the PowerConnect W-series run on a Dell specific version of ArubaOS.

The Dell Networking S- xxxx and Z9x00 series will run on DNOS where the other Dell Networking switches will continue to run FTOS 8.x firmware.

Line 29:

==Capabilities==

All DNOS 9.x based switches offer a wide range of layer2 and layer3 protocols. All features are available on all switches: some switch models (in the S-series) offer an additional license for layer3 or routing: this additional license is NOT required to use that protocol, but only required to get support from the Dell Networking support department on using these features. All interfaces on DNOS 9.x running switches are configured as a layer3 interface and by default shutdown. To use such an interface as an ethernetEthernet switchport you need to configure it as such (with the command "switchport") and then enable that port using "no shutdown".

Unlike DNOS 6.x (which provide web and CLI - with extensive API control via undocumented "dedug console" and "dev help" commands), DNOS 9.x only offers a documented command line interface (CLI) to configure and monitor the switch directly, though it is possible with the "Automation Tools" to create your own webGui on DNOS 9.x switches.

===Layer2 capabilities===

All standardized ethernetEthernet standards are supported by switches running FTOS including: [[Spanning Tree Protocol]] and [[Spanning Tree Protocol#Rapid Spanning Tree Protocol|RSTP]], [[Virtual LAN|VLAN]] and the [[IEEE 802.1Q]] standards, QinQ or [[IEEE 802.1ad]], [[Link Layer Discovery Protocol]] and LLDP MED.

The S-series switches ending with a '''V''' and some of the E-series line-cards support [[Power over Ethernet]] or PoE with the standards for this protocol.

===Layer3 capabilities===

As mentioned above, by default an interface on a switch running DNOS 9.x are configured as a layer3 port. All these switches are thus routers with many interfaces that can (and most often are) reconfigured into a layer2 ethernetEthernet switch.

All DNOS 9 switches run at least the following routing protocols: [[Routing Information Protocol]] and [[Routing Information Protocol#RIP version 2|RIP version 2]], [[Open Shortest Path First|OSPF]], [[IS-IS]] and [[Border Gateway Protocol]] version 4.

==Open Automation==

Under the name OpenAutomation 2.0 Dell Networking switches running DNOS 9.x offers a number of features under this name. These features include:<ref name="oa2">[https://archive.today/20130629011335/http://www.dell.com/learn/us/en/555/solutions/force10-open-automation?c=us&l=en&s=biz Dell Force10 Open Automation 2.0]{{dead link|date=September 2017 |bot=InternetArchiveBot |fix-attempted=yes }}, visited 29 May 2013</ref>

===Smart Scripting===

Line 59:

On some models Dell Networking switches (currently the S3048-ON, S4048-ON, S4810-ON, S6000-ON and Z9100) it is possible to run an alternative network OS: [[Cumulus Networks#Cumulus Linux|Cumulus Linux]]. This will run instead of DNOS on top of NetBSD. Cumulus Linux is a complete Linux distribution which uses the full TCP/IP stack of Linux.<ref>IT Online: [http://it-online.co.za/2014/02/07/dell-decouples-hardware-and-software/ Dell decouples hardware and software], 7 February 2014. visited: 28 April 2014</ref>
