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

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:

In Ethernet mode you won't be able to configure any DSL parameters, but you can use layer 3 Gigabitethernet interface for outside network.

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.
