Configuring Logical Interfaces

Overview

Interfaces of a device are used to exchange data and interact with interfaces of other
network devices. Interfaces are classified into physical interfaces and logical interfaces.
 Physical interfaces are the ports on the front panel or rear panel of the switch.
 Logical interfaces are manually configured and do not physically exist, such as
loopback interfaces and routing interfaces.
This chapter introduces the configurations for logical interfaces. The supported types of
logical interfaces are shown as below:
