Introduction

• CPSW operates in two modes
  • Switch Mode - packet forwarding is enabled and packets are forwarded to Host + Other MAC ports. This is the default configuration for CPSW.
  • MAC mode - packets are only given to the Host port and are not forwarded to other MAC Ports.

CPSW DUAL MAC Mode

• In this mode, both the MAC ports of AM263X are configured to be in MAC mode.
• This mode requires two Network interfaces to operate.
• It is recommended to use two separate subnets for working with DUAL MAC.
• A single implementation of network interface and shared pool is used for both the Netifs.
