IP Address Configuration

IPv4
Switch Interfaces
Layer-3-Switch switchport access vlan
Note: First you have to disable ip routing on the switch with the no ip routing command.

L3-Switch(config)# interface <interface>
L3-Switch(config-if)# no shutdown
L3-Switch(config-if)# description <interface-description>
L3-Switch(config-if)# switchport mode access
L3-Switch(config-if)# switchport access vlan <vlan-number>



Layer-3-Switch routed port
Note: First you have to change your switchport into a routed port with the no switchport command.

L3-Switch(config)# interface <interface>
L3-Switch(config-if)# no switchport
L3-Switch(config-if)# description <interface-description>
L3-Switch(config-if)# ip address <ip-address> <subnet-mask>



Switched Virtual Interface (SVI)
Switch(config)# interface vlan <vlan-number>
Switch(config-if)# description <vlan-interface-description>
Switch(config-if)# ip address <ip-address> <subnet-mask>



Router Interfaces
Router(config)# interface <interface>
Router(config-if)# description <interface-description>
Router(config-if)# ip address <ip-address> <subnet-mask>



Loopback Interfaces
Note: An loopback interface is a stable virtual interface on which you can assign layer 3 addresses. It can be used on Cisco switches and routers.

Switch-or-Router(config)#interface Loopback <loopback-number>
Switch-or-Router(config-if)# ip address <ip-address> <subnet-mask>



IPv6
Switch Interfaces
Layer-3-Switch routed port
Note: First you have to change your switchport into a routed port with the no switchport command.

Switch(config)# interface <interface>
Switch(config-if)# no switchport
Switch(config-if)# description <interface description>
Switch(config-if)# ipv6 address <ip-address>/<subnet-mask>
Switch(config-if)# ipv6 address <link-local ip-address> link-local


Switched Virtual Interface (SVI)
Switch(config)# interface vlan <vlan-number>
Switch(config-if)# description <interface description>
Switch(config-if)# ipv6 address <ip-address>/<subnet-mask>
Switch(config-if)# ipv6 address <link-local ip-address> link-local



Router Interfaces
Router(config)# interface <interface>
Router(config-if)# description <interface-description>
Router(config-if)# ipv6 address <ip-address>/<subnet-mask>
Router(config-if)# ipv6 address <link-local-ip-address> link-local
