Dell Networking 如何使用 USB 下載 N 系列交換器上的韌體

簡介

本文將討論使用 USB 將韌體下載至交換器的程序。

透過 USB 下載韌體至交換器的步驟：

步驟 1

將韌體檔案 （.stk 檔案） 複製到 USB 裝置。

步驟 2

輸入以下命令以確認已偵測到裝置：

show usb device

範例輸出

Console# show usb device
Device Status.................................. Active
Manufacturer................................... xxxxxxxxx
Product Name................................... xxxxxxxxxx
Device Serial Number........................... xxxxxxxxxxxxxxxxxxx
Class Code..................................... 0x0000
Subclass Code.................................. 0x0000
Protocol....................................... 0x0000
Vendor ID...................................... xxxxxx
Product ID..................................... xxxxxx
USB Version Compliance......................... 2.0

步驟 3

將 USB 裝置的韌體檔案複製到交換器的備份分割區。

範例輸出

console# copy usb://N4000v6.5.4.3.stk backup
Transfer Mode.................................. Binary
Data Type...................................... Code
Destination Filename........................... backup
Management access will be blocked for the duration of the transfer
Are you sure you want to start? (y/n) y
File transfer in progress. Management access will be blocked for the duration of the transfer. please wait...
File contents are valid. Copying file to flash...
File transfer operation completed successfully.

步驟 4

輸入以下命令，確認檔案已成功複製到備份磁碟分割。

show version

範例輸出

Console# show version
Machine Description............... Dell Networking Switch
System Model ID................... N4032F
Machine Type...................... Dell Networking N4032F
Serial Number..................... XXXXXXXXXXXXXXXXXXXXX
Manufacturer...................... 0xbc00
Burned In MAC Address............. XXXX.XXXX.XXXX
System Object ID.................. 1.3.6.1.4.1.674.10895.3044
CPU Version....................... XLP308H-B1
SOC Version....................... BCM56842_A1
HW Version........................ 3
CPLD Version...................... 17
unit active      backup      current-active next-active
---- ----------- ----------- -------------- --------------
1    6.2.7.2     6.5.4.3     6.2.7.2        6.2.7.2

步驟 5

輸入以下命令，將備份磁碟分割設定為重新開機後的使用中磁碟分割。

boot system backup

範例輸出

Console# boot system backup
Activating image backup ...

步驟 6

再次輸入以下命令，以驗證「next-active」下是否顯示最新韌體

show version

範例輸出

Console# show version
Machine Description............... Dell Networking Switch
System Model ID................... N4032F
Machine Type...................... Dell Networking N4032F
Serial Number..................... XXXXXXXXXXXXXXXXXXX
Manufacturer...................... 0xbc00
Burned In MAC Address............. XXXX.XXXX.XXXX
System Object ID.................. 1.3.6.1.4.1.674.10895.3044

unit active      backup      current-active next-active
---- ----------- ----------- -------------- --------------
1    6.2.7.2     6.5.4.3     6.2.7.2        6.5.4.3

步驟 7

儲存目前的組態，並重新啟動交換器。交換器應會出現新的韌體代碼。

步驟 8

根據韌體需求升級開機代碼和 CPLD。
