The NAS L2 provides the interface to enable core L2 functionality and related protocols. The following lists the NAS L2 features:

  • Handles the MAC address table
  • MAC learning limit
  • VLAN
  • LAG (link aggregation)
  • Layer 2 mirroring

The NAS L2 exposes the northbound CPS API to enable various applications on the top of this module. To program various L2 functions, the NDI L2 translates the NPU/port to the corresponding SAI instance. As southbound interface, the NDI L2 calls the SAI API which calls the vendor-specific NPU function.
