New features – Broadcom Qumran AX platform

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

SIAD PM25 interface speed configuring auditing

This feature adds an enhancement that restricts the available options for configuring link speed for certain platform interface modules, such that incompatible NIF speeds cannot be configured on the same PM25 (ports 20-27 on the UfiSPace S9500-30XS platform).

Packet snooping in hardware

This feature adds an ad-hoc diagnostic tool that can be used to peek at the frames traversing a particular hardware interface.

This feature is not intended as a comprehensive packet mirroring (SPAN, RSPAN, ERSPAN) feature.

Route variance tracking

This feature extends show ip route variance to include L3 programming in hardware.

show ip route variance tracks deltas between the kernel, RIB, and software dataplane.

Link Aggregation (LAG) support

This feature add supports for LAG on devices using Broadcom Q-AX.

Link Aggregation (LAG) is a mechanism by which a network operator can group multiple interfaces together for the purposes of L2 forwarding for purposes such as resiliency or increased throughput performance. LAG is currently supported in the software forwarding path, but isn't supported for hardware switched/forwarded interfaces.

Q-AX DRAM reclamation

This feature allows the reclamation of external DRAM used by Q-AX which has been marked as errored.

It additionally provides data which can be used in detecting faulty DRAM within the device. ​​ ​

IEEE-1588 (PTP) support for the G.8275.2 telecom profiles

This feature adds support for G.8275.2 telecom profiles with or without assisted partial timing (APTS) support.

Monitoring No-buffer (memory exhaustion) drops

This feature allows a packet buffer monitoring threshold value to be configured by the user for monitoring, traps are generated upon exceeding the threshold.

Per-vlan support for L2 PCP and L3 DSCP

This feature adds support for adding PCP and DSCP classification at a per port or per VLAN level of granularity

QoS queue map based on ingress port

This feature adds support for setting ingress port affinity to egress QoS queue.

This enables DSCP untrusted devices to be classified based on configuration. The expression of the ingress port is configurable at the port and port+VLAN levels.
