Why does the Undo option not receive support for modem upgrades?
A. To support the Undo option, Software Management must determine the version of software that runs and identify the image file on the device that corresponds. The image file must be present in the library or available on Cisco.com. In the case of modem upgrades, Software Management cannot precisely determine the current software version on the modems in all cases. Moreover, different modems can run different software versions, which makes the undo process difficult to support.
