Layer 3 Features:

• Routing Protocols: OSPF, BGP, RIP, IS-IS, and static routing.
• IPv4/IPv6: Full support for IPv4 and IPv6 unicast and multicast routing.
• VRF: Virtual Routing and Forwarding, allowing multiple routing tables to coexist on the same switch.
• ECMP: Supports 128-way Equal-Cost Multi-Path (ECMP) routing for load balancing across multiple network paths.

Advanced Features:

• VXLAN: Hardware-based VXLAN support with VTEP (VXLAN Tunnel Endpoint) for Layer 2 overlay network extension.
• Quality of Service (QoS):
  • Up to 8 egress queues per port.
  • Support for priority queuing, traffic shaping, and scheduling for enhanced QoS control.
• Security:
  • Access Control Lists (ACLs): Layer 2 to Layer 4 packet filtering.
  • MACsec (802.1AE) encryption for secure data transmission.
  • Control Plane Policing (CoPP) to protect the CPU from excessive traffic.
