User Interfaces: Command Line & Web Interface
Industry-standard command line interface (CLI). The CLI is accessed through SSH or Telnet sessions, or directly via the console serial port on the power side panel.
The CLI can be in one of several modes, and each mode makes available a certain group (or level) of commands for execution.
Web interface - WebUI that accepts inputs and provides outputs by generating webpages which can be viewed by the user using a web browser for configuration, monitoring, and troubleshooting.
The inventory in the switch system can be accessed through a SNMP MIB browser. These devices are indexed (entPhysicalIndex) using three levels: Module layer, Device layer & Sensor layer.
System Management
Management Interface
Management interfaces are used in order to provide access to switch management user interfaces (e.g. CLI, WebUI). HPE Switch Management supports out-of-band (OOB) dedicated interfaces (e.g. mgmt0, mgmt1) and in-band dedicated interfaces. In addition, HPE M-Series Switches feature a standard 115200 baud rate RJ45 serial port that provides access to the CLI.
NTP, Clock & Time Zones
Network Time Protocol (NTP) is a networking protocol for clock synchronization between computer systems over packet-switched, variable-latency data networks. NTP is intended to synchronize all participating computers to within a few milliseconds of Coordinated Universal Time (UTC) and is designed to mitigate the effects of variable network latency.
PTP
IEEE Standard for a Precision Clock Synchronization Protocol for Networked Measurement and Control Systems (standard number 1588) defines the means to achieve time synchronization in the orders of sub microseconds.
Software Management
Configuration Management
Onyx's built-in automation infrastructure reduces operational expenses and time to service by minimizing manual operations and eliminating configuration and provisioning errors. Automation tools such as Ansible, SaltStack, ZTP and Puppet enable you to automate fabric configuration and large scale deployments.
Saving, Loading & restore to factory defaults of the Configuration Files
There are two types of configuration files that can be applied on the switch, BIN files (binary) and text-based configuration files. BIN configuration files are not human readable. Additionally, these files are encrypted and contain integrity verification preventing them from being edited and used. Text configuration files are text-based and editable. It is similar in form to the output of the command "show running config expanded". Automated configuration file backup feature can be used to upload the active configuration file on every "configuration write". The switch WEBUI and CLI can be used to load a BIN or text configuration file. By default, or after a system reset, the system loads the default "initial" configuration file. Support is provided to load a different configuration file and make it the active configuration.
Logging
Logging of system events in several severity level over a configurable period of time.
Debugging
Support save sysdmp file collects configuration, status, counters, log files, What-Just-Happened, and WireShark traces for Ethernet modules to enable timely review of problems and facilitate service support. There are 31 per port packet counters and an additional 22 discard packet classification counters to help you identify why there are packet processing problems, should they occur.
What Just Happened (WJH)
As an innovative network telemetry technology, 'What Just Happened' (WJH) monitors and alerts on data plane anomalies to reduce system downtime. With built-in capabilities to inspect packets across all ports at line-rate, multi-terabit speeds, WJH avoids time-consuming data collection and manual searches for network problems. In addition, a streaming WJH telemetry application, supported by other management applications, can be installed as a Docker container.
Link Diagnostic Per Port
Enables an insight into the physical layer components - see information such as a cable status (plugged/unplugged), speed mismatch, auto-negotiation failures, signal quality failures, link training failures, forward error code mismatch, etc.
Signal Degradation Monitoring
A system can monitor the bit error rate (BER) in order to ensure a quality of the link and take an automatic action to disable offending ports.
Telemetry
Sampling (histograms) - a network administrator can enable a sampling of the port buffer occupancy, record occupancy changes over time, and provide information for different levels of buffer occupancy, and amount of time the buffer has been occupied during the observation period.
Thresholds - thresholds may be enabled per port to record the network time when port buffer occupancy crosses the defined threshold and when buffer occupancy drops below it.

Software Components, Standard, Base Models
Ethernet Switching
Interface Isolation
Group interfaces in sets where traffic from each port is isolated from other interfaces in the group.
Link Aggregation Group (LAG)
Several same speed links are combined into a single logical entity with the accumulated bandwidth of the originating ports
MLAG
Extending the implementation of the LAG to more than a single device provides yet another level of redundancy that extends from the link level to the node level.
VLANs
L2 segment of the network which defines a broadcast domain and is identified by a tag added to all Ethernet frames running within the domain
Voice VLAN
Provide QoS to voice and data traffic in a scenario where a terminal is connected to an IP phone which is in turn connected to the port on the switch
QinQ
Segregate the traffic of different customers in their infrastructure, while still giving the customer a full range of VLANs for their internal use by adding a second 802.1Q VLAN tag to an already tagged frame
Spanning Tree
Rapid Spanning Tree Protocol (RSTP) provides for rapid recovery of connectivity following the failure of a bridge/bridge port or a LAN. The following are supported: BPDU Filter, BPDU Guard, Loop Guard, Root Guard, MSTP and RPVST
Virtual routing and forwarding functions (VRFs)
Virtual routing and forwarding (VRF) is a technology included in IP (Internet Protocol) network routers that allows multiple instances of a routing table to exist in a router and work simultaneously. This increases functionality by allowing network paths to be segmented without using multiple devices. Because traffic is automatically segregated, VRF also increases network security.. Currently, OnyxTM supports 64 VRF instances.
OpenFlow - Support for OpenFlow 1.3
OpenFlow is a network protocol that facilitates direct communication between network systems via Ethernet. Software Defined Networks (SDN) allows a centralist management of network equipment. OpenFlow allows the SDN controller to manage SDN equipment. The OpenFlow protocol allows communication between the OpenFlow controller and OpenFlow agent.
VXLAN
VXLAN (Virtual eXtensible Local Area Network) addresses the requirements of the L2 and L3 data center network infrastructure in the presence of virtual networks in a multi-tenant environment. It runs over the existing networking infrastructure and provides a means to "stretch" a L2 broadcast domain over a layer 3 network.
IGMP Snooping
Snooping and updating tables based on the IGMP protocol used by hosts and adjacent routers on IP networks to establish multicast group memberships
Link Layer Discovery Protocol (LLDP)
A vendor-neutral Link Layer protocol in the Internet Protocol Suite used by network devices for advertising their identity, capabilities, and neighbors on a IEEE 802 LAN
Quality of Service (QoS)
QoS Classification, QoS ReWrite, Queuing and Scheduling, RED & ECN are supported
Access Control List
An Access Control List (ACL) is a list of permissions attached to an object, to filter or match switches packets. When the pattern is matched at the hardware lookup engine, a specified action (e.g. permit/deny) is applied
Other QOS features
802.3X Flow Control

Port Mirroring
Port mirroring enables data plane monitoring functionality which allows the user to send an entire traffic stream for testing.
sFlow
sFlow (ver. 5) is a procedure used for statistical monitoring of traffic in networks. MLNX-OS supports an sFlow sampling mechanism (agent), which includes collecting traffic samples and data from counters. The sFlow datagrams are then sent to a central collector.
RDMA over Converged Ethernet (RoCE)
Remote Direct Memory Access (RDMA) is the remote memory management capability that allows server to server data movement directly between application memorywithout any CPU involvement. Simplified RoCEv2 switch configuration automation supported by just one command: roce {lossy | semi-lossless | lossless}.
Priority Flow Control
Provides an enhancement to the existing pause mechanism in Ethernet. The global Ethernet pause option stops all traffic on a link. PFC creates eight separate virtual links on the physical link and allows any of these links to be paused and restarted independently, enabling the network to create a no-drop class of service for virtual links.
Shared Buffers
All successfully received packets by a switch are stored on internal memory from the time they are received until the time they are transmitted. The packet buffer is fully shared between all physical ports and is hence called a shared buffer. Buffer configuration is applied in order to provide lossless services and to ensure fairness between the ports and priorities.
Storm Control
Storm Control is a feature which can be enabled on L2 Ethernet ports and port-channels to monitor inbound traffic to prevent disruptions caused by a broadcast, multicast, or unicast traffic storm on the physical interfaces
Store-and-Forward
Store-and-Forward is used to describe a functionality where a switch receives a complete packet, stores it, and only then forwards it.
Since the switch makes forwarding decisions based on the destination address which is at the header of the packet, the switch can make the forwarding decision before receiving the complete packet. This process is called cut-through, as the switch forwards part of the packet before receiving the complete packet. Cut-through and store-and-forward modes are configurable as a switch global or per port option.
IP Routing
IP Interfaces
The following 3 types of IP interfaces are supported:
VLAN interface
Loopback interface
Router port interface
IPv6
IP version 6 (IPv6) is a routing protocol which succeeds IPv4. With the expansion of the Internet and data bases IPv6 addresses consist of 128 bits whose purpose is to allow networks to include a significantly higher number of nodes by increasing the pool of available unique IP addresses. IPv6 packets alleviate overhead and allow for future customizability.
OSPF
Open Shortest Path First (OSPF) is a link-state routing protocol for IP networks. It uses a link state routing algorithm and falls into the group of interior routing protocols, operating within a single autonomous system (AS).
BGP
Border Gateway Protocol (BGP) is an exterior gateway protocol which is designed to transfer routing information between routers. It maintains and propagates a table of routes which designates network reachability among autonomous systems (ASs).
BGP unnumbered
This BGP feature enables a user to establish a BGP session through a P2P Layer-3 link (port or port-channel) without specifying what the IP address of the remote neighbor is, nor what the neighbor's ASN number is. This feature is useful when provisioning a big data center fabric. It does not require allocation of an IP subnet on each pair of connected switches and simplifies the massive configuration and enabl
