Changes in Conguration Files
Conguration les have three commented lines at the beginning of the le, as shown in the following example, to help you track the last
time any user made a change to the le, which user made the changes, and when the le was last saved to the startup-conguration.
In the running-conguration le, if there is a dierence between the timestamp on the “Last conguration change,” and “Startup-cong
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

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 buer.
The system generates a trace message for each executed command. No password information is saved to the le.
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 10:57:12]: CMD-(CLI):hostname Force10

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.
NOTE
: If VLT is already congured in a device loaded with Dell Networking OS version 9.9(0.0), you must rst remove the VLT
conguration to upgrade to the Dell Networking OS version 9.10(0.0) or later. After removing the VLT conguration, upgrade
each VLT node and its corresponding single-homed PE individually and then reload both nodes as well as PEs. After the CBs and
PEs come up with Dell Networking OS version 9.10(0.0) or later, congure VLT again. When you congure VLT, the PEs rst go
down and then come up.
