簡介
本檔案介紹如何在Cisco 800系列路由器上升級超高位速率數位使用者線路(VDSL)韌體。
必要條件
需求
思科建議您在完成此升級過程之前檢視韌體版本的發行說明。
採用元件
本檔案中的資訊是根據Cisco 897VAB路由器。但是本檔案所述內容不限於特定軟體和硬體版本。
本文中的資訊是根據特定實驗室環境內的裝置所建立。文中使用到的所有裝置皆從已清除（預設）的組態來啟動。如果您的網路正在作用，請確保您已瞭解任何指令可能造成的影響。

確定路由器上的當前韌體版本
輸入show controller vdsl命令以確定Cisco 800系列路由器上當前韌體的版本。在此示例輸出中查詢以粗體顯示的輸出條目：

附註：預設韌體放在flash:/firmware/<filename>中。如果VDSL控制器下沒有給定韌體路徑，並且重置VDSL控制器(shut/no-shut)或重新載入路由器；vdsl控制器採用此預設韌體。請勿從flash:/firmware/<filename>中刪除基本韌體。
升級VDSL韌體
- 從Cisco.com軟體中心下載新的VDSL2韌體。
- 選擇Routers > Branch Routers > Cisco 800 Series Routers > Cisco 887V Integrated Services Router > Very High Bitrate DSL(VDSL)Firmware。
- 將韌體複製到指定位置。例如，路由器快閃記憶體或TFTP伺服器。
以下示例展示如何將VDSL2韌體從10.76.76.160上的TFTP伺服器複製到路由器快閃記憶體中：
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，您可以輸入copy ftp://usernamepassword@TFTP-Server-IPAddress flash:VDSL-Firmware-Name命令。以下輸出提供範例：
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]
- 將路由器配置為從指定位置載入新的VDSL2韌體。
Router#conf t

- 重新啟動控制器介面以使新韌體生效：
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#controller vdsl 0
Router(config-controller)#shut
Router(config-controller)#no shut
Router(config-controller)#end
