If an IP address or VRRP group is assigned to the interface, you cannot use the
switchport command on the interface. To use the switchport command on an
interface, only the no ip address and no shutdown statements must be
listed in the
show config output.
When you enter the switchport command, the interface is automatically added
to the default VLAN.
To use the switchport backup interface command on a port, first enter the
switchport command. For more information, see the “Configuring Redundant
Links” section in the “Layer 2” chapter of the
