Active Port Configuration
Information
This command applies the port-configuration information that exists in
physical memory to the chips that control the I/O ports. This makes it
possible to restore the I/O ports to the state that they were in during full
physical memory restore operations (i.e., download all request).

Use this command to replace the working configuration with the
permanent configuration. This command saves the current active I/O
port-configuration information into the processor’s physical memory. It is
normally used as part of a physical upload operation where the processor
memory and configuration are to be fully saved.
The edit resource is required for this operation.
Command Parameters
