Managing SCTs
Downloading SCT Files to the Switch
When you want to download a new or modified SCT file, you can download the file using CWM or by
using an FTP program. If you have used CWM to create or modify an SCT or if you are using CWM to
manage your SCTs, it is best to use CWM to download and to register the file. For more information,
refer to the Cisco WAN Manager User’s Guide, Release 15.1.
When using an FTP program, copy the files to the C:SCT/TEMP directory on the switch. For the latest
information on Cisco provided SCTs, refer to the following release note documents:
• Release Notes for Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, and Cisco MGX 8830
Switches, Release 5.1.00
• Release Notes for the Cisco MGX 8880 Media Gateway, Release 5.0.02
For more information on transferring files to the switch, see the “Copying Software Files to the Switch”
section in Appendix A, “Downloading and Installing Software Upgrades.”
After you download a file to a switch, you must register the SCT on the switch if it has not been
registered before, or you must update a preregistered SCT. The next two sections describe how to
register SCT files and how to update previously registered SCT files.
Registering SCT Files
SCT files must be registered on a switch before they can be used to configure card and port
communications. The registration process checks for version conflicts and registers SCTs with CWM
when CWM is used for network management.
The primary goal of SCT registration is to prevent the confusion that can result when two SCT files with
the same name contain different configurations. Registration on a switch ensures that no two registered
SCT files have the same name. When CWM is used to manage SCTs on a network, CWM can be used
to prevent different configurations for the same file name within the network, and CWM can be used to
distribute and register SCTs to multiple switches simultaneously. To learn how to manage SCT files with
CWM, refer to the Cisco WAN Manager User’s Guide, Release 15.1.
There are three types of registration:
• Auto registration during an upgrade
• Registration directed by CWM
• Manual registration initiated in the CLI
Autoregistration is used during upgrades from releases that did not support registered SCT files. Auto
registration registers SCT files that were in use before the upgrade.
When an SCT is autoregistered or registered through CWM, there is no need to manually register the
SCT. To view registered SCTs, use the dspscts command as described in “Displaying all Registered
Card and Port SCTs on a Switch,” which appears later in this chapter.
If the dspscts command display does not show the SCT you want to use, you can manually FTP an SCT
file to the switch and then manually register that SCT. If the upgrade files are copied to the switch as
described in the “Copying Software Files to the Switch” section in Appendix A, “Downloading and
Installing Software Upgrades,” you can manually register the SCT using the procedure described later
in this section.
When you manually register an SCT, the SCT is moved from a temporary directory to the directory
where registered SCTs are stored. You cannot use SCTs that are stored in the temporary directory. Once
an SCT is registered, it is removed from the temporary directory so that it cannot be registered again.
