ccna 200 301 syllabus definition pluralisme.% IP addresses maynot be configured onL2 links.Command error,prompt :LP addresses cannot be configured on a Layer 2 interface. By default, even the port on a Layer 3 switch is a Layer 2 port, and since it is a Layer 2 port, it cannot be configured with an IP address, whereas the ports on router routing modules are Layer 3 ports by default, and can be configured directly.SWl(config-if)#intvlan 1VLAN1 (Virtual Local Area Network 1). By default, all ports on the switch are cut-through ports. The VL dias port, also known as the virtual routing port, is a Layer 3 port and can be configured with an IP address. You can manage the switch remotely through the work P address of the VL heart interface. SWl (config-if) #ip add 1.1.1.2 255.255.255.0 Configure the work P address for the VLAN interface. SWl (config-if)#no shut7Interrogate the interface to explain that it is a Layer 3 port. A good practice is to use the "no shut" command for all Layer 3 ports to activate them. And the switch on the Layer 2 ports are activated by default, do not need to use the "no shut" command to activate, buy a switch, connected to the computer can be used directly, because all the ports on the switch are open by default. The 6 on the switch is a layer 2 interface by default , you do not need to use the "n. shut" command to activate.SWl(config-if)#exit283SWl (config)#no ip routing The Layer 2 Switch is not supported for routing protocols ,use the "no ip routing^ call to turn off the routing function of the routing switch.SWl(config)#ip default-gateway1.1.1.1For a device that does not support routing protocols ,the way to configure a default route is to configure a gateway. Because the computer does not support routing protocols by default, the default gateway is configured. For a device that supports routing protocols, the default route is configured using / route 0.0.0.0 0.0.0.0^&
