Chapter 3 Basic Router Configuration
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
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 |
|
|
| |
|
|
|
Step 2 | ip address | Sets the IP address and subnet mask for the |
| Example: | specified Fast Ethernet interface. |
|
| |
|
| |
| 255.255.255.0 |
|
|
| |
|
|
|
Step 3 | no shutdown | Enables the Ethernet interface, changing its |
|
| state from administratively down to |
| Example: | administratively up. |
|
| |
|
| |
|
|
|
Step 4 | exit | Exits configuration mode for the Fast Ethernet |
|
| interface and returns to global configuration |
| Example: | mode. |
|
| |
| 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
