58 Configuring & Monitoring The Switch ELS100-24TXGDownloading Via TFTPTo perform a TFTP download, you must first configure the ELS100-24TXG switch. This consists of programming the switch with an IPaddress, if this has not already been done, and entering the IP address ofthe TFTP server and the name of the upgrade file. To program the switchIP address, go to the System Configuration Menu which is accessiblefrom the Main Menu screen.To download switch software via TFTP, do the following:1. Select TFTP Server IP Address from the Download Software Menu.2. Enter the TFTP server IP address and press [Enter].3. Select TFTP File Name and enter the file name to be downloadedfrom the TFTP server.4. If necessary, configure the address of an IP gateway to reach theserver from the switch using the Default Gateway field on the SystemConfiguration Menu.5. Configure the TFTP server by copying the download file to theappropriate directory and starting the server.6. Select Start TFTP Download and press [Enter].To verify that the TFTP download has been successfully completed,note the software version level displayed on the General Informationscreen accessible from the Main Menu. This number should matchthe version number of the downloaded file.Configuring Spanning Tree ParametersThe ELS100-24TXG switch supports the IEEE 802.1D Spanning TreeProtocol. This protocol allows redundant connections to be createdbetween LAN segments for purposes of fault tolerance. Two or morephysical paths between different segments can be created through theswitch, with the Spanning Tree Protocol choosing a single path at anygiven time and disabling all others.If the chosen path fails for any reason, a disabled alternative is activated,thereby maintaining the connection. See Appendix B, “Spanning TreeConcepts,” for further information on using the Spanning Tree Protocol ina network.For a TFTP download, the path to the file must be in-cluded in its name. For example, if the upgrade filename is filename.bin and it resides in the directory /usr/tftp on the TFTP server, then you must enter theTFTP file name as: “/usr/tftp/filename.bin”.
