Releases and Patches into the Switch
The LOADER module is responsible for loading and storing releases, patches and other files into FLASH. The LOADER module uses the Trivial File Transfer Protocol (TFTP), Hypertext Transfer Protocol (HTTP) or ZMODEM over an asynchronous port, to retrieve files from a network host. The FFS module is used to create, write and destroy release and patch files.
The loader can be configured with the command:
SET LOADER [DELAY=delayDEFAULT] [DESTINATION={FLASHDEFAULT}] [FILE=filename] [HTTPPROXY={hostnameipaddDEFAULT}] [METHOD={HTTPTFTPWEBWWWZMODEMNONEDEFAULT}] [ASYN=portDEFAULT] [PROXYPORT=1..65535DEFAULT] [SERVER={hostnameipaddDEFAULT}]
This command sets default values for the name of the file to load, the network host to load it from, and the memory location in which to store the file. These default values can be overridden when the load actually takes place. A time delay between initiating a load and the start of the load can also be configured.
The DELAY parameter specifies the delay, in seconds, between initiating the file download and the download actually starting. This feature is provided to allow reconfiguration of ports and devices after initiating the download. For example, a manager may be at a remote site with a single PC which is to act as both the access device to the switch and the TFTP server. By specifying a delay, the manager has time to reconfigure the PC from terminal emulation mode to TFTP server mode before the download starts. The DELAY parameter is optional. If DEFAULT is specified, this parameter is set to the factory default, which is no delay.
The DESTINATION parameter specifies where the file will be stored. If FLASH is specified, the file is stored in the FLASH File System (FFS) on the switch. If DEFAULT is specified, this parameter is set to the factory default, FLASH.
The FILE parameter specifies the name of the file, in the syntax of the server from which the file will be downloaded. The FILE parameter is a full path name rather than just a file name. The only restriction is that the last part of the parameter must be a valid file name for the LOADER module. When METHOD is set to TFTP, HTTP, ZMODEM or NONE, valid file names are of the form filename.ext where filename is one to eight characters in length and ext is three characters in length. The following are examples of valid file names for methods TFTP, ZMODEM or NONE:
\user\public\filename.ext ; UNIX or DOS server [network.cfg]filename.ext ; DEC VAX server
Note that, starting at the end of the file name and working backwards, the first character not valid in file names delimits a valid file name for the switch. If the slash at the beginning of the path is omitted in this command, the LOAD command adds it. The following are examples of valid file names for method HTTP:
/path/filename.ext
path/filename.ext
The HTTPPROXY parameter specifies the proxy server used to handle HTTP requests. Either the IP address or the fully qualified domain name of the proxy server may be specified. If a domain name is specified, the switch will perform a DNS lookup to resolve the name. If DEFAULT is specified, this parameter is
