B.3.6 Deleting AU Images from the NPU Flash
The NPU flash can store a maximum of three AU images. When you download a
new AU image to the NPU flash, the oldest image (that is not mapped to any AU) is
overwritten. It is recommended that you frequently delete AU images that are no
longer required in the NPU flash.
To delete an AU image from the NPU flash, run the following command:
npu(config)# erase au image <au image name>
Syntax

required to first delete the corresponding mapping, and then delete the image from the NPU flash.

AU-to-Image Mapping” on page 708
