* Slide 1 of 1 Purpose: Emphasize: Notice that there are more commands available on the router than the Cat 1900 switch. * Slide 1 of 1 Purpose: Emphasize: Notice that there are more commands available on the router than the Cat 1900 switch. * Slide 1 of 1 Purpose: This page shows the interface configuration mode. Emphasize: The top line is the format of the command used in fixed-port routers. The type field shows the interface type, which can be Ethernet, Token Ring, or another interface. The number field is the number of the interface. For example, if the router has two Ethernet interfaces, and one is known as Ethernet0, the other will be called Ethernet1. The second command is used on the Cisco 7000 and 7200 series routers, which can accept multiple interface cards with multiple ports on each card. In this case, the first number is the number of the card, or slot number. The second number is the port on the card. For example, on the second interface card, the first Ethernet interface is specified as Ethernet 2/0. If you have Cisco 7000 and 7500 series routers with VIP cards, you define an interface in the by slot, port adapters, and port numbers. Port adapters are assigned either a 0 or 1 number. Use the exit command to leave the current configuration mode. * Slide 1 of 2 Purpose: This page shows examples of the commands used to configure a serial interface. Emphasize: Layer 1— In this example, we are configuring the serial interface from the console port. The configure terminal command puts us in global configuration mode. Once in global configuration mode, you must identify the specific interface against which you will be issuing commands. Notice after you enter the specific interface command that the prompt now indicates you are in interface configuration mode. * Slide 1 of 1 Purpose: Emphasize: Cat 1900 switch also uses the “shut” and “no shut” command. * Slide 1 of 1 Purpose: This slide shows you how to verify the changes you make to an interface
