New features – Broadcom Qumran AX platform

New CLI commands associated with the new features can be found in the configuration section.

Hardware switch integration (Qumran AX)

This release builds on previous releases and continues to extend the hardware capabilities of the Qumran AX based whitebox platform.

Control Plane policing (Qumran AX)

This feature helps protect the Control Plane by using a QoS filter to manage the flow of Control Plane packets destined to it.

This feature provides rate limiting on a selection of protocols and other selection criteria, and for each selection criteria, the maximum number of packets allowed per-second (pps) or kilobits per-second (kbps) to be sent to the Control Plane are configurable.

Layer 3 ACL support (Qumran AX)

This feature provides, stateless IP Packet filter support in hardware.

This feature adds the ability to block outbound locally sourced traffic, inbound locally destined traffic and transit traffic. The filter support is only provided for non-reassembled packets and only affects L3 packets which are L3 processed, for example an L3 packet which is L2 forwarded between links in a VLAN would not be affected.

Layer 3 GRE support (Qumran AX)

This feature provides support for L3 Generic Routed Encapsulation (GRE) tunnel termination over IPv4 & IPv6 in the hardware packet processing pipeline.

Initially, some limitations exist and these include no support for GRE keys, L2 GRE or mGRE tunnels.

IPv4/IPv6 Multicast support (Qumran AX)

This feature provides Multicast packet replication and forwarding for IPV4 and IPv6 packets in the hardware forwarding path.

This will cover the following PIM protocol modes:
  • PIM Dense mode (DM)
  • PIM Sparse Mode (SM)
  • PIM Source specific Multicast (SSM)
The support will also cover receipt from, and replication to the following interface types:
  • Ethernet
  • Ethernet vif
  • Switch Vif
  • GRE Tunnel
Existing Qumran AX based QoS shaping will be supported for Multicast traffic.

IEEE-1588 Precision Time Protocol (PTP) MIB support (RFC8173)

This feature provides support for the PTP MIB as defined in RFC8173.

L1/L2 optical interface breakout support (Qumran AX)

The interface breakout feature allows high-bandwidth ports to be 'broken out' into multiple ports of lower bandwidth.

This feature provides a mechanism to increase the port density on an existing platform and the ability to connect to other network equipment operating at lower speeds.

The common breakout modes supported are:
  • 100G to 4 x 25G
  • 40G to 4 x 10G
