Changes in Configuration Files Configuration files have three commented lines at the beginning of the file, as shown in the following example, to help you track the last time any user made a change to the file, which user made the changes, and when the file was last saved to the startup-configuration. In the running-configuration file, if there is a difference between the timestamp on the "Last configuration change," and "Startup-config last updated," you have made changes that have not been saved and will not be preserved after a system reboot. Example of the show running-config Command Dell#show running-config Current Configuration ... ! Version 1-0(0-4013) ! Last configuration change at Wed Jun 3 16:24:25 2015 by admin ! boot system rpm0 primary system: A: boot system rpm0 secondary tftp://10.16.127.35/DT-MAA-C9000-3 boot system rpm0 default system: A: boot system rpm1 primary system: A: boot system rpm1 secondary tftp://10.16.127.35/DT-MAA-C9000-3 boot system rpm1 default system: A: boot system gateway 10.16.127.148 ! service timestamps log datetime ! logging coredump ! hostname Dell ! Viewing Command History The command-history trace feature captures all commands entered by all users of the system with a time stamp and writes these messages to a dedicated trace log buffer. The system generates a trace message for each executed command. No password information is saved to the file. To view the command-history trace, use the show command-history command. Example of the show command-history Command Dell#show command-history [12/5 10:57:8]: CMD-(CLI):service password-encryption [12/5 10:57:12]: CMD-(CLI):hostname Force10 [12/5 10:57:12]: CMD-(CLI):ip telnet server enable [12/5 10:57:12]: CMD-(CLI):line console 0 [12/5 10:57:12]: CMD-(CLI):line vty 0 9 Upgrading the Dell Networking OS To upgrade the Dell Networking operating system on the switch, refer to the Release Notes for the software version you want to load.
