配置檔案恢復

當需要備份中恢復交換機配置時，可以通過configdownload命令將博科交換機的配置從遠端伺服器恢復到交換機。博科交換機支援將舊版本的配置檔案匯入新版本韌體的交換機，例如將v6.2.0的配置檔案匯入v6.3.0韌體版本的交換機，或者將v6.4.1 配置檔案匯入 v7.0.0 版本的交換機。

如果將配置檔案匯入到不相容的韌體版本交換機，可能導致交換機故障。建議經常儲存配置檔案，確保備份的配置檔案與交換機韌體版本相同。

韌體v6.1.0及以後的版本，恢復配置檔案時不需要disableswitch。某些特殊情況下，恢復配置檔案以後會提示你重啟交換機。

*** CAUTION ***
This command is used to download a backed-up configuration
for a specific switch. If using a file from a different
switch, this file's configuration settings will override
any current switch settings. Downloading a configuration
file, which was uploaded from a different type of switch,
may cause this switch to fail. A switch reboot might be
required for some parameter changes to take effect.
configDownload operation may take several minutes
to complete for large files.

韌體升級

升級韌體前，檢視一下根分割槽的磁碟容量，如果使用率超過60%，建議聯絡Brodecade技術支援處理。

FCSwitch:root> df
Filesystem           1k-blocks      Used Available Use% Mounted on
/dev/root               495016    165432    304032  35% /
/dev/hda1               494984    165712    303724  35% /mnt

檢視交換機當前韌體版本：

升級過程一般需要10到30分鐘，你可以使用firmwareDownloadStatus 命令來檢視升級狀態。

FCSwitch:root> firmwareDownloadStatus
[1]: Tue Feb 14 06:29:33 2012
Firmware is being downloaded to the switch. This step may take up to 30 minutes.

[2]: Tue Feb 14 06:33:27 2012
Firmware has been downloaded to the secondary partition of the switch.

[3]: Tue Feb 14 06:35:49 2012
