View 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 are preserved after a system reboot.
Example of the show running-config Command
DellEMC#show running-config
Current Configuration ...
! Version 9.4(0.0)
! Last configuration change at Tue Mar 11 21:33:56 2014 by admin
! Startup-config last updated at Tue Mar 11 12:11:00 2014 by default

Compressing Configuration Files
You can optimize and reduce the sizes of the configuration files.
You can compress the running configuration by grouping all the VLANs and the physical interfaces with the same property.
Support to store the operating configuration to the startup config in the compressed mode and to perform an image downgrade
without any configuration loss are provided.
You can create groups of VLANs using the interface group command. This command will create nonexistent VLANs
specified in a range. On successful command execution, the CLI switches to the interface group context. The configuration
commands inside the group context will be the similar to that of the existing range command.
Two existing exec mode CLIs are enhanced to display and store the running configuration in the compressed mode.
show running-config compressed and write memory compressed
The compressed configuration will group all the similar looking configuration thereby reducing the size of the configuration. For
this release, the compression will be done only for interface related configuration (VLAN & physical interfaces)
The following table describes how the standard and the compressed configuration differ:
