This example shows how to delete the interface-range macro enet_list and to verify that it has been
deleted.

Configuring Ethernet Interfaces
The switch supports these interface types:
•Physical ports—Switch ports, including access and trunk ports
•Port channels—EtherChannel of interfaces
•VLANs
These sections describe the default interface configuration and the optional features that you can
configure on most physical interfaces:
•Default Ethernet Interface Configuration, page 7-9
•Configuring Interface Speed and Duplex Mode, page 7-10
•Adding a Description for an Interface, page 7-12

Default Ethernet Interface Configuration

Table 7 -1 shows the Ethernet interface default configuration. For more details on the VLAN parameters
listed in the table, see Chapter12, “Configuring VLANs.” For details on controlling traffic to the port,
see Chapter15, “Configuring Port-Based Traffic Control.”
