Introduction
This document describes WAN Mode feature on Cisco867VAE Platform and the options which enable the DSL Internet Services.
Prerequisites
Requirements
There are no specific requirements for this document.
Components Used
The information in this document is based on Cisco867VAE Platform.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.
Configure
Here is the configuration to enable WAN Modes on CISCO867VAE Platform:
Cisco867VAE(config)#wan mode ?
dsl WAN interface is DSL
ethernet WAN interface is ethernet
DSL Mode
—————
This mode allows to configure your DSL parameters on ATM or Ethernet but not on any layer 3 interface, that is Gigabitethernet 0 in this device.
Cisco867VAE#sh ip int brief
Interface IP-Address OK? Method Status Protocol
ATM0 unassigned YES NVRAM administratively down down
Ethernet0 unassigned YES NVRAM administratively down down
FastEthernet0 unassigned YES unset up up
FastEthernet1 unassigned YES unset down down
FastEthernet2 unassigned YES unset down down
FastEthernet3 unassigned YES unset down down
GigabitEthernet0 unassigned YES NVRAM down down
Vlan1 10.106.47.21 YES NVRAM up up
Here are the error messages encountered when in DSL mode:
Cisco867VAE(config)#wan mode dsl
% Ethernet WAN interface will be disabled.
Cisco867VAE(config)#

Ethernet Mode:
In Ethernet mode you won't be able to configure any DSL parameters, but you can use layer 3 Gigabitethernet interface for outside network.
Cisco867VAE#wan mode ethernet
% DSL interfaces will be disabled.

To disable WAN mode is not possible when it is in DSL mode as its the default mode in CISCO 867 platform.
But when disabled in Ethernet mode, it changes to DSL mode.
Cisco867VAE(config)#no wan mode dsl
Cisco867VAE(config)#do sh run | sec wan
wan mode dsl
Cisco867VAE(config)#do sh run | sec wan
wan mode ethernet
Cisco867VAE(config)#no wan mode ethernet
% Ethernet WAN interface will be disabled.

Verify
Use this section to confirm that your configuration works properly.
Cisco867VAE#sh run | inc wan mode
wan mode dsl
