CISCO在推出C2960/C3560这一时代的产品后，系统数据包都是tar归档格式了，不光包含了传统bin文件，还包含了http server的文件，功能大大加强。系统文件升级备份操作也与原来有很大的不同。
Instead of using the copy privileged EXEC command or the archive tar privileged EXEC command, we recommend using the archive download-sw and archive upload-sw privileged EXEC commands to download and upload software image files.
archive download-sw /allow-feature-upgrade privileged EXEC command to allow installation of an image with a different feature set, for example, upgrading from the IP base image to the IP services image.
升级操作：
Step3 | archive download-sw /allow-feature-upgrade /overwrite /reload tftp:[[//location]/directory]/image-name.tar | Download the image file from the TFTP server to the switch, and overwrite the current image.
The /allow-feature-upgrade option allows installation of an image with a different feature set.
The /overwrite option overwrites the software image in flash memory with the downloaded image.
The /reload option reloads the system after downloading the image unless the configuration has been changed and not been saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive. | |
Step4 | archive download-sw /leave-old-sw /reload tftp:[[//location]/directory]/image-name.tar | Download the image file from the TFTP server to the switch, and keep the current image.
The /leave-old-sw option keeps the old software version after a download.
The /reload option reloads the system after downloading the image unless the configuration has been changed and not been saved.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the image to download. Directory and image names are case sensitive. | |
备份操作：
Step3 | archive upload-sw tftp:[[//location]/directory]/image-name.tar | Upload the currently running switch image to the TFTP server.
For //location, specify the IP address of the TFTP server.
For /directory/image-name.tar, specify the directory (optional) and the name of the software image to be uploaded. Directory and image names are case sensitive. The image-name.tar is the name of the software image to be stored on the server. | |
例子：
archive tar /create tftp:// 192.168.255.100/c3560-ipbase-mz.122-55.SEB4.tar flash:/c3560-ipbase-mz.122-55.SEB4
archive upload-sw tftp://192.168.255.100/c3560-ipservicesk9-mz.122-55.SE.tar
格外注意文件路径格式。
