Chapter 5 Basic Router Configuration

Configuring WAN Interfaces

DETAILED STEPS

	Command	Purpose
Step 1
	interface type number	Enters the configuration mode for a Gigabit
	Example:	Ethernet WAN interface on the router.
	Router(config)# interface gigabitethernet 0
	Router(config-if)#
Step 2
	ip address ip-address mask	Sets the IP address and subnet mask for the
	Example:	specified Gigabit Ethernet interface.
	Router(config-if)# ip address 192.168.12.2
	255.255.255.0
	Router(config-if)#
Step 3
	no shutdown	Enables the Ethernet interface, changing its
	Example:	state from administratively down to
		administratively up.
	Router(config-if)# no shutdown
	Router(config-if)#
Step 4
	exit	Exits configuration mode for the Gigabit
	Example:	Ethernet interface and returns to global
		configuration mode.
	Router(config-if)# exit
	Router(config)#

Configuring the Cellular Wireless WAN Interface

The Cisco 819 ISRs provide a Third-Generation (3G) wireless interface for use over Global System for Mobile Communications (GSM) and code division multiple access (CDMA) networks. The interface is a 34-millimetre embedded mini express card.

Its primary application is WAN connectivity as a backup data link for critical data applications. However, the 3G wireless interface can also function as the router’s primary WAN connection.

To configure the 3G cellular wireless interface, follow these guidelines and procedures:

•Prerequisites for Configuring the 3G Wireless Interface, page 5-11
