Compressing Configuration Files
The functionality to optimize and reduce the sizes of the configuration files is supported on the device.
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
non-existant 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.

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:
