Chapter 9 Managing Controller Software and Configurations

Transferring Files to and from a Controller

Using the CLI to Download Configuration Files

Using the controller CLI, follow these steps to download a configuration file to the controller.

Note The controller does not support incremental configuration downloads. The configuration file contains all

mandatory CLIs (all interface address CLIs, mgmtuser with read-write permission CLIs, and interface

port or LAG enable or disable CLIs) required to successfully complete the download. For example, if

you download only config time ntp server index server_address as part of the configuration file, the

download fails. Only the CLI commands present in the configuration file are applied to the controller,

and any configuration in the controller prior to the download is removed.

Step 1 To specify the transfer mode used to download the configuration file, enter this command:

transfer download mode {tftp | ftp}

Step 2 To specify the type of file to be downloaded, enter this command:

transfer download datatype config

Step 3 If the configuration file is encrypted, enter these commands:

• transfer encrypt enable

• transfer encrypt set-key key, where key is the encryption key used to decrypt the file

Note The key that you enter here should match the one entered during the upload process.

Step 4 To specify the IP address of the TFTP or FTP server, enter this command:

transfer download serverip server-ip-address

Step 5 To specify the directory path of the configuration file, enter this command:

transfer download path server-path-to-file

Step 6 To specify the name of the configuration file to be downloaded, enter this command:

transfer download filename filename

Step 7 If you are using a TFTP server, enter these commands:

• transfer download tftpMaxRetries retries

• transfer download tftpPktTimeout timeout

Note The default values of 10 retries and a 6-second timeout should work correctly without any

adjustment. However, you can change these values. To do so, enter the maximum number of

times that the TFTP server attempts to download the software for the retries parameter and the

amount of time (in seconds) that the TFTP server attempts to download the software for the

timeout parameter.
