18 / 324 page  Product Overview VMDS-10488 VSC7511 Datasheet Revision 4.2 3 2 Product Overview The VSC7511 Industrial IoT Ethernet switch contains four ports, each configurable as either an integrated 10/100/1000BASE-T PHY or a 1G SGMII/SerDes. In addition, there is an option for either a 1G/2.5G SGMII/SerDes Node Processor Interface (NPI) or a PCIe interface for external CPU connectivity. The NPI/PCIe can operate as a standard Ethernet port. The device provides a rich set of Industrial Ethernet switching features such as fast protection switching, 1588 precision time protocol, and synchronous Ethernet. Advanced TCAM-based VLAN and QoS processing enable delivery of differentiated services. Security is assured through frame processing using Microsemi’s TCAM-based Versatile Content Aware Processor. In addition, the device contains an 8051 CPU for simple operation of the switch. The device supports the following main port configurations. 2.1 General Features • 1.75 megabits of integrated shared packet memory • 4 x 1G SGMII or integrated copper PHY ports • Fully nonblocking wire-speed switching performance with weighted random early detection (WRED) for all frame sizes • Eight QoS classes and eight queues per port with strict or deficit weighted round robin scheduling • Dual leaky bucket policers, per QoS class and per port • Dual leaky bucket policers, flow-based through TCAM matching • DWRR and strict priority egress scheduler/shaper and 9 dual leaky bucket shapers per egress port. • TCAM-based classification entries for Quality of Service (QoS) and VLAN membership • TCAM-based host identity entries for source IP guarding • TCAM-based security enforcement entries • TCAM-based egress tagging entries • L1 Synchronous Ethernet • VeriTime™—Microsemi’s patent-pending distributed timing technology that delivers the industry’s most accurate IEEE 1588v2 timing implementation for both one-step and two-step clocks • Audio/Video bridging (AVB) with support for time-synchronized, low-latency audio and video streaming services • Energy Efficient Ethernet (IEEE 802.3az) • VCore-Ie™ CPU system with integrated 250 MHz 8051 CPU with 64 KB internal storage • PCIe and 2.5G SGMII NPI for external CPU register access • Device overheat protection • Hardware loop detection • Integrated fan controller • Internal shared memory buffer (8 queues per port) Integrated 10/100/1000BASE-T Ethernet copper transceiver (IEEE 802.3ab compliant) with the industry's only non-TDR-based VeriPHY™ cable diagnostics algorithm • Patented line driver with low EMI voltage mode architecture and integrated line-side termination resistors • Wake-on-LAN using magic packets • HP Auto-MDIX and manual MDI/MDIX support 2.1.1 Layer 2 Switching • 4,096 MAC addresses • 4,096 VLANs (IEEE 802.1Q) Table 1 • Main Port Configurations Ports 1G CuPHY/SGMII 2.5G NPI PCIe 4 + NPI 4 1 4 + PCIe 4 1 |
