VSC7511 Overview
VSC7511 4-Port Layer-2 Gigabit Ethernet Switch INTRODUCTION 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.
VSC7511 Key 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
- 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
