Chapter 9 Configuring the Switch Interfaces
Configuring Switch Interfaces
This example shows how to define an interface-range macro named enet_list to select Fast Ethernet
ports 1 to 4 and to verify the macro configuration:
Switch# configure terminal
Switch(config)# define interface-range enet_list fastethernet0/1 - 4
Switch(config)# end
Switch# show running-config | include define
define interface-range enet_list FastEthernet0/1 - 4
This example shows how to create a multiple-interface macro named macro1:
Switch# configure terminal
Switch(config)# define interface-range macro1 gigabitethernet0/1 - 2, fastethernet0/5 - 7
Switch(config)# end
Switch#
This example shows how to enter interface range configuration mode for the interface-range macro
enet_list:
Switch# configure terminal
Switch(config)# interface range macro enet_list
Switch(config-if-range)#
This example shows how to delete the interface-range macro enet_list and to verify that it has been
deleted.
Switch# configure terminal
Switch(config)# no define interface-range enet_list
Switch# show run | include define
Configuring Switch Interfaces
The switch supports these interface types:
• Physical ports—Switch ports, including access, trunk, and LRE ports
• VLANs—Switch virtual interfaces (SVIs)
• Port-channels—EtherChannel of interfaces
These sections describe the default interface configuration and the optional features that you can
configure on most physical interfaces:
• Default Ethernet Interface Configuration, page 9-10
• SFP Configuration, page 9-10
• Configuring Interface Speed and Duplex Mode, page 9-11
• Configuring Media Types for Gigabit Interfaces, page 9-14
• Configuring IEEE 802.3X Flow Control on Gigabit Ethernet Ports, page 9-14
• Adding a Description for an Interface, page 9-16
