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.
