Configuring Interface Characteristics
This chapter defines the types of interfaces on the Catalyst 3750 switch and describes how to configure
them. Unless otherwise noted, the term switch refers to a standalone switch and a switch stack.
The chapter consists of these sections:
• Understanding Interface Types, page 11-1
• Using Interface Configuration Mode, page 11-10
• Configuring Ethernet Interfaces, page 11-15
• Configuring Layer 3 Interfaces, page 11-25
• Configuring the System MTU, page 11-27
• Monitoring and Maintaining the Interfaces, page 11-28
Note For complete syntax and usage information for the commands used in this chapter, see the switch
command reference for this release and the online Cisco IOS Interface Command Reference,
Release 12.2.
Understanding Interface Types
This section describes the different types of interfaces supported by the switch with references to
chapters that contain more detailed information about configuring these interface types. The rest of the
chapter describes configuration procedures for physical interface characteristics.
Note The stack ports on the rear of the switch are not Ethernet ports and cannot be configured.
These sections describe the interface types:
• Port-Based VLANs, page 11-2
• Switch Ports, page 11-2
• Routed Ports, page 11-4
• Switch Virtual Interfaces, page 11-5
• EtherChannel Port Groups, page 11-6
• 10-Gigabit Ethernet Interfaces, page 11-6
