This article explains how to modify a configuration file using the tftp command in the CLI.
Step-by-step guide
To update a configuration file using the tftp command follow the steps listed below. The syntax for the tftp command is "tftp -g -t w -f filename server_ip", where “filename” is the name of the modified configuration file and “server_ip” is the actual IP address of the tftp server.
- Open the configuration file on the modem and search for the X_SMARTRG_COM_CustomerSpecificConfig tag.
- Verify that the factory default configuration lines highlighted in red are present.
<X_SMARTRG_COM_CustomerSpecificConfig> < X_SMARTRG_COM_CustomerName>UndefinedCustomerName</X_SMARTRG_COM_CustomerName> < X_SMARTRG_COM_ConfigFileServer>192.168.1.100</X_SMARTRG_COM_ConfigFileServer> < X_SMARTRG_COM_ConfigFilePath>/path/to/SR505n/configfiles/</X_SMARTRG_COM_ConfigFilePath> < X_SMARTRG_COM_UsernameSuffix>@somedomain.com</X_SMARTRG_COM_UsernameSuffix> < X_SMARTRG_COM_ConfigFileDownloadInterval>2160</X_SMARTRG_COM_ConfigFileDownloadInterval> < X_SMARTRG_COM_ConfigFileVersion>UndefinedIdentString-00000001</X_SMARTRG_COM_ConfigFileVersion> < X_SMARTRG_COM_ActivateTftpDownload>FALSE</X_SMARTRG_COM_ActivateTftpDownload> < X_SMARTRG_COM_ActivateCustomPPPUsernamePass>FALSE</X_SMARTRG_COM_ActivateCustomPPPUsernamePass> < /X_SMARTRG_COM_CustomerSpecificConfig>
- Modify the fields as explained in the table below.
- Save and close the file.
Field | Description |
CustomerName | Replace “UndefinedCustomerName” with your vendor name. |
ConfigFileServer | Replace “192.168.1.100” with the IP address or URL of your TFTP server. |
ConfigFilePath | Replace “/path/to/SR505n/configfiles/” with the path to the config file on the TFTP server. |
UsernameSuffix | Replace “@somedomain” with the domain value for the address of tftp server. |
ConfigFileDownloadInterval | Accept the default setting of “2160” or enter your preferred time interval (in seconds) for the config file to download. |
ConfigFileVersion | Replace “UndefinedIdentString-00000001” with the name and version of the config file on the TFTP server in the following format: cfgxxxxxxxxxxxx-########.conf where xxxxxxxxxxxx is the MAC address of the modem and ######## is the version of the config file, e.g., cfg00236A4DDB42-00000009.conf. Important: For a new config file to load, the version of the new file must be greater than the version of the current file or the "Illegal file upload" error appears. |
ActivateTftpDownload | Replace “FALSE” with “TRUE”. |
