Changes in Conguration Files
Conguration 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-conguration.
In the running-conguration le, if there is a dierence between the timestamp on the “Last conguration change,” and “Startup-cong
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 buer.
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 10:57:8]: CMD-(CLI):service password-encryption
[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 congured in a device loaded with Dell Networking OS version 9.9(0.0), you must rst remove the VLT
conguration to upgrade to the Dell Networking OS version 9.10(0.0) or later. After removing the VLT conguration, 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, congure VLT again. When you congure VLT, the PEs rst go
down and then come up.
