However, if you do change the setting to p2p, you will see this setting when you enter the show running config command. Use the switchport command to convert a Layer 3 interface into a Layer 2 interface. Command switchport Example: switch(config-if)# switchport Purpose Configures the interface as a Layer 2 interface and deletes any configuration specific to Layer 3 on this interface. This example shows how to configure a routed interface: switch# configure terminal switch(config)# interface ethernet 2/1 switch(config-if)# no switchport switch(config-if)# ip address 192.0.2.1/8 switch(config-if)# copy running-config startup-config The default setting for interfaces is routed. If you want to configure an 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. Configuring a Subinterface You can configure one or more subinterfaces on a routed interface or on a port channel made from routed interfaces. BEFORE YOU BEGIN Configure the parent interface as a routed interface. See the "Configuring a Routed Interface" section on page 4-6. Create the port-channel interface if you want to create a subinterface on that port channel. Ensure that you are in the correct VDC (or use the switchto vdc command).

Configuring Layer 3 Interfaces
Configuring Layer 3 Interfaces
Note
The default setting is
broadcast
, and this setting does not appear in any of the
show
commands.
However, if you do change the setting to
p2p
, you will see this setting when you enter the
show running
config
command.
Use the
switchport
command to convert a Layer 3 interface into a Layer 2 interface.
This example shows how to configure a routed interface:
switch#
configure terminal
switch(config)# i
nterface ethernet 2/1
switch(config-if)#
no switchport
switch(config-if)#
ip address 192.0.2.1/8
switch(config-if)#
copy running-config startup-config
The default setting for interfaces is routed. If you want to configure an 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.
Configuring a Subinterface
You can configure one or more subinterfaces on a routed interface or on a port channel made from routed
interfaces.
BEFORE YOU BEGIN
Configure the parent interface as a routed interface.
See the
“Configuring a Routed Interface” section on page 4-6
.
Create the port-channel interface if you want to create a subinterface on that port channel.
Ensure that you are in the correct VDC (or use the
switchto vdc
command).
SUMMARY STEPS
1.
configure terminal
2.
interface ethernet
slot/port.number
3.
ip address
ip-address/length
or
ipv6 address
ipv6-address/length
4.
encapsulation dot1q
vlan-id
5.
(Optional) show interfaces
6.
(Optional) copy running-config startup-config
Command
Purpose
switchport
Example:
switch(config-if)#
switchport
Configures the interface as a Layer 2 interface and
deletes any configuration specific to Layer 3 on
this interface.
