Compressing Configuration Files - Dell S4048T Configuration Manual

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:
