Configuring Layer 3 Interfaces Overview

Overview
Interfaces are used to exchange data and interact with interfaces of other network devices.
Interfaces are classified into Layer 2 interfaces and Layer 3 interfaces.
■ Layer 2 interfaces are the physical ports on the switch panel. They forward packets
based on MAC address table.
■ Layer 3 interfaces are used to forward IPv4 and IPv6 packets using static or dynamic
routing protocols. You can use Layer 3 interfaces for IP routing and inter-VLAN routing.
This chapter introduces the configurations for Layer 3 interfaces. The supported types of
Layer 3 interfaces are shown as below:
