简介
本文档介绍如何在Cisco 800系列路由器上升级超高比特率数字用户线路(VDSL)固件。
先决条件
要求
思科建议您在完成此升级过程之前检查固件版本的发行说明。
使用的组件
本文档中的信息基于Cisco 897VAB路由器。但是，本文档不限于特定软件和硬件版本。
本文档中的信息都是基于特定实验室环境中的设备编写的。本文档中使用的所有设备最初均采用原始（默认）配置。如果您使用的是真实网络，请确保您已经了解所有命令的潜在影响。
配置
注意：使用命令查找工具（仅限注册用户）可获取有关本部分所使用命令的详细信息。
确定路由器上的当前固件版本
输入show controller vdsl命令以确定Cisco 800系列路由器上当前的固件版本。查找此示例输出中以粗体显示的输出条目：

注意：默认固件放置在flash:/firmware/<filename>中。如果在VDSL控制器下未提供固件路径，并且VDSL控制器已重置(关闭/不关闭)或路由器已重新加载；VDSL控制器采用此默认固件。请勿从flash:/firmware/<filename>中删除基本固件。
升级VDSL固件
- 从Cisco.com软件中心下载新的VDSL2固件。
- 选择Routers > Branch Routers > Cisco 800系列路由器 > Cisco 887V集成多业务路由器 > Very High Bitrate DSL(VDSL)Firmware。
- 将固件复制到指定位置。例如，路由器闪存或TFTP服务器。
本示例显示如何将VDSL2固件从TFTP服务器10.76.76.160复制到路由器闪存：
Router#copy tftp flash:
Address or name of remote host []? 10.76.76.160 [Addres of the TFTP Server]
Source filename []? vdsl_bond.bin_39p1 [Name of the downloaded VDSL Firmware]
Destination filename [vdsl_bond.bin_39p1]? [Name of the VDSL firmware on the router flash]
或者，您可以输入copy ftp://usernamepassword@TFTP-Server-IPAddress flash:VDSL-Firmware-Name命令。此输出提供一个示例：
Router#copy ftp://test:test@10.76.76.160 flash:vdsl_bond.bin_39p1
Source filename []? vdsl_bond.bin_39p1
Destination filename [vdsl_bond.bin_39p1]?
Accessing ftp://test:test@10.76.76.160/vdsl_bond.bin_39p1...
Loading vdsl_bond.bin_39p1 !!!!!!!!!!!
[OK - 2660422/4096 bytes]
- 将路由器配置为从指定位置加载新的VDSL2固件。

Router(config)#controller vdsl 0
Router(config-controller)#shut
Router(config-controller)#no shut
