在 Cisco 897 上配置 VDSL？它不会拨号！

我是 Cisco 产品的新手，一直在遵循一些在线指南，其中详细说明了要求设置的步骤，但我陷入了一些陈规。据我所知，我相信所有正确的接口都已配置并配置了拨号程序。任何人都可以发现任何明显的错误并帮助兄弟吗？非常感谢您！

请问有人可以帮忙吗？我显然错过了一些非常明显的东西！

您的 DSL 未使用 ATM。如果它应该是 ADSL/ATM，那么您需要设置 VDSL 控制器以明确使用它。自动检测正在查找 VDSL2/PTM。

如果 PTM 是正确的，那么一切都会通过Ethernet0。正如@jonathanjo 指出的那样，可能有 VLAN 标记以及 PPPoE，或者它可能像 Et0 上的 DHCP 一样简单。（或者它可能需要 dot1x，而 897 无法做到。）

我不知道您何时必须配置ATM0以及何时使用ethernet0.101（如果您知道，请发表评论！），但是带有 VDSL 的 Cisco 867VAE（在英国）在其配置中包含以下内容：

wan mode dsl
controller VDSL 0
!
interface ATM0
 no ip address
 shutdown
 no atm ilmi-keepalive
!
interface Ethernet0
 no ip address
 no cdp enable

interface Ethernet0.101
 encapsulation dot1Q 101
 pppoe-client dial-pool-number 1

interface Dialer1
 ip address negotiated
 ip nat outside
 ip virtual-reassembly in

 ip tcp adjust-mss 1400
