Configuring Ethernet Interfaces
This example shows how to define an interface-range named enet_list to include ports 1 and 2 on
switch 1 and to verify the macro configuration:
Switch# configure terminal
Switch(config)# define interface-range enet_list gigabitethernet1/0/1 - 2
Switch(config)# end
Switch# show running-config | include define
define interface-range enet_list GigabitEthernet1/0/1 - 2
This example shows how to create a multiple-interface macro named macro1:
Switch# configure terminal
Switch(config)# define interface-range macro1 fastethernet1/0/1 - 2, gigabitethernet1/0/1
- 2
Switch(config)# end
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 was deleted.
Switch# configure terminal
Switch(config)# no define interface-range enet_list
Switch(config)# end
Switch# show run | include define
Switch#

Default Ethernet Interface Configuration
Table 11-2 shows the Ethernet interface default configuration, including some features that apply only
to Layer 2 interfaces. For more details on the VLAN parameters listed in the table, see Chapter 13,
“Configuring VLANs.” For details on controlling traffic to the port, see Chapter 25, “Configuring
Port-Based Traffic Control.”
