Restricted Characters and System Upgrades
As part of the upgrade to SR 2.5/3.5 and SR 4.0, Cisco engineers check for restricted
characters in download file names. Should a download file name contain a restricted
character, engineers correct the file name so that only valid characters are used.
characters in download file names. Should a download file name contain a restricted
character, engineers correct the file name so that only valid characters are used.
The user interface of the DNCS does not yet filter for restricted characters. Hence,
the system operator could, theoretically, still configure a download file that is named
using a restricted character. A download file named with a restricted character is
never added to the CVT and, therefore, DHCTs never download the code.

In addition, never include a blank space (Spacebar or Tab) in a download file name.
Correcting File Names That Contain a Restricted Character
A future service pack for SR 2.5/3.5 and SR 4.0 will contain filters for the DNCS user
interface that will prevent restricted characters from being used as part of a
download file name. In the meantime, should you inadvertently name a download
file using a restricted character, follow these instructions to correct the situation.
1 Delete the associated download.
2 Delete the download file.
3 Recreate the download file using only valid characters in the file name.
4 Recreate the download.
