OcNOS provides a software-based solution for network switches and routers, offering a flexible and open approach to networking.

Key Features of OcNOS:

OcNOS works with applications in diverse network environments, including data centers, service provider networks, enterprise networks, and cloud deployments. It provides an open, flexible environment and extensive protocol support for software-defined networking (SDN) and disaggregated networks.

OcNOS SP Release 6.5.2 introduces a new Broadcom Qumran-2C based Aggregation Router, along with several software features, and product enhancements.

IP Infusion moved to a three-digit release version number from a two-digit release version number. An integer indicates major, Minor, and Maintenance release versions. Build numbers are for internal tracking and verification of the software build process and are visible to customers as part of the software version number.

Product Name: IP Infusion Product Family

Major Version: New customer-facing functionality that represents a significant change to the code base; in other words, a significant marketing change or direction in the product.

Minor Version: Enhancements/extensions to existing features, external needs, or internal requirements might be motivated by improvements to satisfy new sales regions or marketing initiatives.

Maintenance Version: It is a collection of product bugs/hotfixes and is usually scheduled every 30 or 60 days, based on the number of hotfixes.

Higher data rate transceivers are equipped with Clock Data Recovery (CDR) to ensure the transmitted and received signals are synchronized for optimal transmission.

Some higher data rate transceivers running at a lower data rate are not supported because the clock fails to lock, causing an unstable link. To mitigate jitter generation, the CDR (Clock and Data Recovery) must be bypassed. For instance, on a 100G-LR4 transceiver that supports 4 lanes at 25Gbps, reducing the lane speed to 10Gbps results in jitters. This occurs when the clock tries to lock onto 25Gbps, while the actual data rate is 10Gbps. In these cases, the RX and TX CDR must be bypassed on both connected devices.

For more information, refer to the Interface Commands section in the OcNOS System Management Guide, Release 6.5.2.

Multiple tagged VLANs help address previous database synchronization challenges. It ensures seamless operation and reliability when adding multiple tagged VLANs, saving configurations, and reloading the device.

For more information on ZTP, refer to the Automatic Install using Zero Touch Provisioning section in the OcNOS Installation Guide, Release 6.5.2.

For more information, refer to the VPLS - Per-Peer VPLS-type Signaling section in the MPLS Guide, Release 6.5.2.

The Layer 2 switch treats the received multicast packet as unknown when there is no explicit group join request from any of the hosts for the destination group. The unknown multicast traffic is either forwarded to all ports (except the ingress port) within the VLAN or discarded.

A new command l2 unknown mcast (flood|discard) is introduced to implement this capability.

This feature enables the option to drop the unknown multicast traffic in any snooping configurations. For example, execute the command in the IGMP Snooping Configuration or MLD Snooping Configuration.

This feature is supported on Qumran platforms. It reduces the traffic at the egress node and efficiently uses the hardware resources.

For more information, refer to the l2 unknown mcast CLI command reference section in the OcNOS Multicast Configuration Guide, Release 6.5.2

The Remote Authentication server behavior is enhanced to support auto enabled privilege level mode based on the user role specified in the authentication server. A new CLI disable default auto-enable is introduced to implement it. Executing this CLI removes the default access to the privilege execute mode to any user.

For more information, refer to the Restricted Access to Privilege Mode based on User Role CLI command reference in the System Management Configuration Guide Release 6.5.2.

The remote authentication servers RADIUS or TACACS are enhanced to support the full fledged AAA solution for serial console connection using the default and management VRF. For more information refer to the AAA Configuration for Console Connection section in the OcNOS System Management Guide, Release 6.5.2.

The sFlow monitoring system is enhanced to add more collectors to receive sample data for analysis. For more information, refer to the Configure sFlow for Multiple Collectors section in the OcNOS System Management Guide, Release 6.5.2

For more information, refer to the Event Manager section in the OcNOS System Management Guide, Release 6.5.2.

OcNOS enhances streaming telemetry capabilities, including dial-out subscription method, poll mode subscriptions, once mode subscriptions, support for the OpenConfig data model, PROTO/JSON encodings, and in-band telemetry in the global and user-defined VRFs. These enhancements benefit network operators by enabling continuous data streaming, on-demand data retrieval, and the availability of additional data models for streaming telemetry.

Dial-out telemetry or persistent subscriptions ensure continuous data streaming even if the gRPC session terminates unexpectedly. This mode simplifies telemetry subscription configuration and management using standard OpenConfig and IPI data models, enhancing network monitoring and troubleshooting capabilities. Additionally, it facilitates reliable communication between the OcNOS device and collector servers, ensuring uninterrupted data flow for improved network visibility and operational efficiency.

For more information, refer to the Streaming Telemetry Dial-Out Mode section in the OcNOS Streaming Telemetry Guide, Release 6.5.2.

Poll mode subscriptions allow for on-demand data retrieval through a long-lived RPC. Subscribers initiate this mode by sending a Subscribe request message, followed by sending an empty Poll message to receive the desired data.

In Once mode subscription, the OcNOS device responds to a subscribe request with a one-time data retrieval, similar to a get request. Upon receiving the “Once mode” subscribe request, the device sends back the subscribe response for all subscriptions in the list and terminates the RPC.

OcNOS supports the OpenConfig data model for both Dial-In and Dial-Out operations. Users can specify the type of XPath (openconfig or ipi) in the origin field of the provided path, allowing for efficient and flexible telemetry configurations. Also, introduces new states that provide insights into the operational status and attributes of various components,

For more information, refer to Streaming Telemetry Data Models section in the OcNOS Streaming Telemetry Guide, Release 6.5.2.

Enhances streaming encoding support by adding PROTO and JSON formats for Dial-in and Dial-out subscriptions. PROTO encoding enables efficient data serialization between clients and the OcNOS device using protobuf messages. This enhancement streamlines data transmission, allowing for fast communication.

JSON encoding extends encoding support to include quoted string values and unquoted number values. JSON encoding is the default setting when the encoding type is unspecified, improving interoperability and simplifying configuration for network operators.

OcNOS enhances gNMI In-Band support to enable streaming telemetry data transmission across any one of the default, management, or user-defined VRFs using the new VRF parameter feature streaming-telemetry (vrf (NAME|management)|). If no specific VRF is configured, streaming telemetry is automatically enabled within the default VRF. This facility increases flexibility in network management by allowing telemetry data transmission across different VRFs.

The gNMI server now listens for incoming gRPC connections on the IANA-defined standard gNMI port number 9339, replacing the previous non-standard port 11162.

The source field in the dial-out gNMI response now uses the MAC address associated with the management port of the host machine or target (e.g., e8:c5:7a:fe:fd:32) instead of the constant string gnmi_target. This change ensures that each gNMI device has a unique target ID, allowing the collector to distinguish responses between different targets.

For more information, refer to the OcNOS Streaming Telemetry Guide, Release 6.5.2.

OcNOS introduces the Internet Protocol Flow Information Export (IPFIX) Exporter, which enhances network traffic analysis through real-time flow monitoring and sampling. The IPFIX Exporter enables administrators to select and export flow records containing traffic information, facilitating insights into network behavior and patterns. It streamlines network management tasks, optimizes resource utilization, and provides visibility into network traffic for improved monitoring and troubleshooting capabilities.

For more information, refer to the IP Flow Information Export section in the OcNOS System Management Guide, Release 6.5.2.

The port breakout functionality supports the division of 100GbE ports into distinct configurations, such as 4x10GbE, 4x25GbE, and 2x50GbE, using a secure and highly reliable breakout cabling solution. Networks today demand a combination of interface speeds, including 10Gb, 25Gb, 40Gb, and 100Gb Ethernet, to accommodate a diverse range of flexible connectivity options. Additionally, cost-effective cabling solutions are crucial to address connectivity needs and facilitate smooth migrations as network speeds and density requirements evolve.

The port breakout feature offers the flexibility to split a 100G port into 4X10G, 4X25G, or 2X50G ports. When performing a port breakout on the 100G port (ce1), the original port (ce1) is replaced by four 10G ports, namely ce1/1, ce1/2, ce1/3, and ce1/4. All Layer 2 (L2) and Layer 3 (L3) features applicable to normal ports can be executed on these breakout ports.

For more information, refer to the Dynamic Port Breakout (100G) on Qumran AX and MX section in the OcNOS System Management Guide, Release 6.5.2.

Signal integrity in the context of Quad Small Form Factor Pluggable Double Density (QSFP-DD) refers to the maintenance and quality of electrical signals transmitted and received by the QSFP-DD module. QSFP-DD is a high- speed, high-density interface used primarily in data center applications to interconnect switches, servers, and other networking equipment.

Maintaining signal integrity is crucial in high-speed data transmission because any degradation or distortion of the signals can lead to errors, reduced performance, or even cause a complete failure of communication between devices. In the case of QSFP-DD, which supports data rates of up to 400 Gbps per port, ensuring signal integrity is particularly challenging due to the high data rates and the compact form factor of the module.

This feature provides a way to override the default transceiver signal integrity settings in case they are not enough to achieve a stable electrical connection with the host side peer.

For more information, refer to the Signal Integrity in QSFP-DD section in the OcNOS System Management Guide, Release 6.5.2.
