Downloading The Software Version Automatically - Zte ZXR10 2900E series Configuration Manual

ZXR10 2900E Series Configuration Guide
To prevent damage to the configuration data, back up the configuration data by using the
tftp command.
Run the following commands to upload the configuration file in the Flash memory to the
back-end TFTP server:
zte(cfg-tffs)#cd cfg
zte(cfg-tffs)#tftp 192.168.1.102 upload startrun.dat
zte(cfg-tffs)#cd ..
Recovering the Configuration File
Run the following commands to download the configuration file in the back-end TFTP
server to the Flash memory:
zte(cfg-tffs)#cd cfg
zte(cfg-tffs)#tftp 192.168.1.102 download startrun.dat
zte(cfg-tffs)#cd ..
Backing Up the Version File
Similar to the configuration file, you can use the tftp command to upload the front-end
version file to the back-end TFTP server. For example:
zte(cfg-tffs)#cd img
zte(cfg-tffs)#tftp 192.168.1.102 upload zImage
zte(cfg-tffs)#cd ..
Recovering the Version File
Version file recovery is used to retransmit the back-end backup version file to the front
end through TFTP. Recovery is very important in the case of upgrade failure. The version
recovery operation is basically the same as the version upgrade procedure.

4.6 Downloading the Software Version Automatically

The automatic software version download function is used for an un-deployed device.
When the switch is powered on for the first time, it identifies that the automatic download
flag is set (factory default setting) in the NVRAM and no configuration file exists, so
automatic download is triggered.
The switch obtains the version file name and/or the configuration file name by interacting
with a DHCP server, and downloads the files by interacting with a TFTP server. If the
download succeeds (even if one file is downloaded successfully), the automatic download
flag in the NVRAM is cleared and the switch is restarted.
For the relation between the file names transferred by the DHCP server and the triggered
download operations, refer to the table below:
