Functional Descriptions
This section provides information about the functional aspects of the VSC7511 Industrial IoT Ethernet
switch device, available configurations, operational features, and testing functionality.
3.1
Port Numbering and Mappings
The switch core contains an internal port numbering domain where ports are numbered from 0 through
11. A port connects to a port module, which connects to an interface macro, which connects to I/O pins
on the device. The interface macros are SERDES6G or copper transceivers.
Some ports are internal to the device and do not connect to port modules or interface macros. For
example, internal ports are used for frame injection and extraction to the CPU queues.
The following table shows the default port numbering and how the ports map to port modules and
interface macros.
Ports 11 is an internal port used for injection and extraction of frames towards a CPU. It does not have an
associated port module and interface macro.
The following table shows the fixed mapping from interface macros to the device I/O pins.
