Usage Guidelines

You can configure any Ethernet port as a routed interface. When you configure an interface as a Layer 3 interface, any configuration specific to Layer 2 on this interface is deleted.

If you want to configure a Layer 3 interface for Layer 2, enter the switchport command. Then, if you change a Layer 2 interface to a routed interface, enter the no switchport command.

Examples

This example shows how to enable an interface as a Layer 3 routed interface: 


switch(config)# interface ethernet 1/5
switch(config-if)# no switchport
switch(config-if)#

This example shows how to configure a Layer 3 interface as a Layer 2 interface: 


switch(config)# interface ethernet 1/5
switch(config-if)# switchport
switch(config-if)#
