The Network Adaptation Service (NAS) handles the networking functionality. The NAS daemon listens to netlink events for Layer 2 and Layer 3 configurations, and programs the NPU.

You have two available methods for network configuration — using the SONiC Object Library APIs or Linux commands (Linux native APIs).

Using SONiC Object Library APIs

• Interfaces — Physical, link aggregation, VLAN, fanout (4x10G) using scripts
• Layer 2 Bridging — LLDP, MAC address table, STP, VLAN
• Layer 3 Routing — ECMP, IPv4, IPv6, Unicast
• Security — QoS, ACL
• Monitoring — Port monitoring, sFlow, port and VLAN statistics

Using Linux Commands (Linux Native APIs)

• Interfaces — Physical, link aggregation (bond), VLAN
• Layer 2 Bridging — LLDP, STP, VLAN
• Layer 3 Routing — ECMP, IPv4, IPv6, Unicast

Unavailable Features using Linux Commands

• Fanout interface configuration
• Layer 2 MAC address table configuration
• QoS and ACL configuration
• Port monitoring, sFlow configuration, and port and VLAN statistics
