title: Ocelot Externally-Controlled Ethernet Switch
maintainers:
- Colin Foster <colin.foster@in-advantage.com>
description: |
The Ocelot ethernet switch family contains chips that have an internal CPU
(VSC7513, VSC7514) and chips that don't (VSC7511, VSC7512). All switches have
the option to be controlled externally via external interfaces like SPI or
PCIe.
The switch family is a multi-port networking switch that supports many
interfaces. Additionally, the device can perform pin control, MDIO buses, and
external GPIO expanders.
