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

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