Configuring WAN Interfaces

Configuring a Fast Ethernet WAN Interface

To configure the Fast Ethernet interface on a Cisco 861 or 881 ISR, perform these steps, beginning in global configuration mode:

SUMMARY STEPS

1.interface type number

2.ip address ip-address mask

3.no shutdown

4.exit

	DETAILED STEPS
	Command	Purpose
Step 1	interface type number	Enters the configuration mode for a Fast
	Example:	Ethernet WAN interface on the router.
	Router(config)# interface fastethernet 4
	Router(config-if)#
Step 2	ip address ip-address mask	Sets the IP address and subnet mask for the
	Example:	specified Fast 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
		state from administratively down to
	Example:	administratively up.
	Router(config-if)# no shutdown
	Router(config-if)#
Step 4	exit	Exits configuration mode for the Fast Ethernet
		interface and returns to global configuration
	Example:	mode.
	Router(config-if)# exit
	Router(config)#

Configuring a VDSL2 WAN Interface

The VDSL2 WAN interface is used on the Cisco 887V ISR platforms. Note that the VDSL2 WAN interface uses Ethernet as the Layer 2 transport mechanism. To configure VDSL2 on the Cisco 887V ISR, perform these steps, beginning in global configuration mode.

SUMMARY STEPS

1.controller vdsl 0

2.interface type number

3.ip address ip-address mask
