Compressing Conguration Files
You can optimize and reduce the sizes of the conguration les.
You can compress the running conguration by grouping all the VLANs and the physical interfaces with the same property. Support to
store the operating conguration to the startup cong in the compressed mode and to perform an image downgrade without any
conguration loss are provided.
You can create groups of VLANs using the interface group command. This command will create nonexistent VLANs specied in a
range. On successful command execution, the CLI switches to the interface group context. The conguration 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 conguration in the compressed mode.

The compressed conguration will group all the similar looking conguration thereby reducing the size of the conguration. For this release,
the compression will be done only for interface related conguration (VLAN & physical interfaces)
The following table describes how the standard and the compressed conguration dier:
