13 Configuring Layer3 Interfaces
13.1 Overview
3 types of Layer3 interface are supported:
• VLAN interfaces: You should configure VLAN interfaces for any VLANs for which
you want to route traffic. VLAN interfaces are created when you enter a VLAN Id
following the interface vlan global configuration command. To delete a VLAN
interface, use the no interface vlan global configuration command.
• Routed Ports: Ports are physical ports configured to be in Layer 3 mode by using
the no switchport interface configuration command.
• Layer 3 Link Aggregation Ports: Link Aggregation interfaces made up of routed
ports.
A Layer 3 switch can have an IP address assigned to each routed port and VLAN
interface. All Layer 3 interfaces require an IP address to route traffic. This procedure
shows how to configure an interface as a Layer 3 interface and how to assign an IP
address to an interface.
13.2 Configuring routed port
This chapter describes configuring routed port and using them. All physical interfaces
can be configured as routed port by using the no switchport interface configuration
command. Follow these steps to configure a routed port.
13.2.1 Configurations
DUT1#configure terminal
Enter the Configure mode.
DUT1(config)#interface eth-0-1
Specify the interface (eth-0-1)to be configured and enter the
Interface mode.
DUT1(config-if)#no switchport
Configure on physical port only, change this port to Layer3
interface.
DUT1(config-if)#no shutdown
Enable this interface.
DUT1(config-if)#ip address 1.1.1.1/24
Configure IP address to 1.1.1.1/24.
DUT1(config-if)#end
Return to privileged EXEC mode.
DUT1#show ip interface brief
Verify the configuration.
13.2.2 Validation
Commands
DUT1#show ip interface brief
Interface IP-Address Status Protocol
eth-0-1 1.1.1.1 up up
DUT1#show ip interface
