This series provides the Microchip Sparx5 Switch Driver
The Sparx5 Carrier Ethernet and Industrial switch family delivers 64 Ethernet
ports and up to 200 Gbps of switching bandwidth.
It provides a rich set of Ethernet switching features such as hierarchical QoS,
hardware-based OAM and service activation testing, protection switching,
IEEE 1588, and Synchronous Ethernet.
Using provider bridging (Q-in-Q) and MPLS/MPLS-TP technology, it delivers MEF CE
2.0 Ethernet virtual connections (EVCs) and features advanced TCAM
classification
in both ingress and egress.
Per-EVC features include advanced L3-aware classification, a rich set of
statistics, OAM for end-to-end performance monitoring, and dual-rate policing
and shaping.
Time sensitive networking (TSN) is supported through a comprehensive set of
features including frame preemption, cut-through, frame replication and
elimination for reliability, enhanced scheduling: credit-based shaping,
time-aware shaping, cyclic queuing, and forwarding, and per-stream
policing and filtering.
Together with IEEE 1588 and IEEE 802.1AS support, this guarantees low-latency
deterministic networking for Fronthaul, Carrier, and Industrial Ethernet.
The Sparx5 switch family consists of following SKUs:
- VSC7546 Sparx5-64
up to 64 Gbps of bandwidth with the following primary port configurations:
- 6 *10G
- 16 * 2.5G + 2 * 10G
- 24 * 1G + 4 * 10G
- VSC7549 Sparx5-90
up to 90 Gbps of bandwidth with the following primary port configurations:
- 9 * 10G
- 16 * 2.5G + 4 * 10G
- 48 * 1G + 4 * 10G
- VSC7552 Sparx5-128
up to 128 Gbps of bandwidth with the following primary port configurations:
- 12 * 10G
- 16 * 2.5G + 8 * 10G
- 48 * 1G + 8 * 10G
- VSC7556 Sparx5-160
up to 160 Gbps of bandwidth with the following primary port configurations:
- 16 * 10G
- 10 * 10G + 2 * 25G
- 16 * 2.5G + 10 * 10G
- 48 * 1G + 10 * 10G
- VSC7558 Sparx5-200
up to 200 Gbps of bandwidth with the following primary port configurations:
- 20 * 10G
- 8 * 25G
In addition, the device supports one 10/100/1000/2500/5000 Mbps SGMII/SerDes
node processor interface (NPI) Ethernet port.
The Sparx5 support is developed on the PCB134 and PCB135 evaluation boards.
- PCB134 main networking features:
- 12x SFP+ front 10G module slots (connected to Sparx5 through SFI).
- 8x SFP28 front 25G module slots (connected to Sparx5 through SFI high
speed).
- Optional, one additional 10/100/1000BASE-T (RJ45) Ethernet port
(on-board VSC8211 PHY connected to Sparx5 through SGMII).
- PCB135 main networking features:
- 48x1G (10/100/1000M) RJ45 front ports using 12xVSC8514 QuadPHY’s each
connected to VSC7558 through QSGMII.
- 4x10G (1G/2.5G/5G/10G) RJ45 front ports using the AQR407 10G QuadPHY each
port connects to VSC7558 through SFI.
- 4x SFP28 25G module slots on back connected to VSC7558 through SFI high
speed.
- Optional, one additional 1G (10/100/1000M) RJ45 port using an on-board
VSC8211 PHY, which can be connected to VSC7558 NPI port through SGMII using
a loopback add-on PCB)
This series provides support for:
- SFPs and DAC cables via PHYLINK with a number of 5G, 10G and 25G devices
and media types.
- Port module configuration for 10M to 25G speeds with SGMII, QSGMII,
1000BASEX, 2500BASEX and 10GBASER as appropriate for these modes.
- SerDes configuration via the Sparx5 SerDes driver (see below).
- Host mode providing register based injection and extraction.
- Switch mode providing MAC/VLAN table learning and Layer2 switching offloaded
to the Sparx5 switch.
- STP state, VLAN support, host/bridge port mode, Forwarding DB, and
configuration and statistics via ethtool.
More support will be added at a later stage.
