Default Ethernet Interface Configuration
Table 9-2 shows the Ethernet interface default configuration. For more details on the VLAN parameters
listed in the table, see Chapter 10, “Configuring VLANs.” For details on controlling traffic to the port,
see Chapter 19, “Configuring Traffic Control.”
Note To configure Layer 2 parameters, if the interface is in Layer 3 mode, you must enter the switchport
interface configuration command without any parameters to put the interface into Layer 2 mode. This
shuts down the interface and then re-enables it, which might generate messages on the device to which
the interface is connected. When you put an interface that is in Layer 3 mode into Layer 2 mode, the
previous configuration information related to the affected interface might be lost, and the interface is
returned to its default configuration.
