Note Users do not have write access to the F:SCT /<card_type> directory. The only way to download SCT
files to the F: directory is to download them to your C:/SCT/Temp directory first. For instructions on
downloading and installing SCT files to your switch, see the “Installing SCT Files” section in
Appendix A, “Downloading and Installing Software Upgrades.”
Before you can assign an SCT to a card or port, you must first download the latest SCT files onto your
switch. To find the location of the latest SCT files and verify that you need to update them, see the
Release Notes for Cisco MGX 8850 and MGX 8830 Software Version 3 (PXM45/B and PXM1E). SCT
files can be manually downloaded onto each node in your network through the CLI, or you can also use
Cisco WAN Manager (CWM). The preferable way of downloading a SCT is by using CWM. To create
additional SCT files or change the configuration of existing SCT files, you need to use (CWM).
You can not create or modify SCT files using the CLI.
Note Port SCTs can be changed with connections provisioned on the port. However, the port needs to be
administratively downed to effect this change. Hence this is service affecting.
After you create a SCT file with CWM, you must use FTP to transfer that file to the switch before you
can use it. For guidelines on transferring files to the switch, see the “Copying Software Files to the
Switch” section in Appendix A, “Downloading and Installing Software Upgrades.” Be sure to copy SCT

The following sections describe how to select SCTs for cards and ports.
Selecting a Card SCT
A card SCT defines the queue parameters for the destination slot based cell queues towards the backplane.
The same card SCT may be used for multiple cards of the same card type.
Note An SCT must reside in your switch F:/SCT directory before you can select it for a card or port. For
instructions on manually downloading and installing SCTs to your switch, see “Installing SCT Files” in
Appendix A, “Downloading and Installing Software Upgrades.”
To select an SCT for a card, use the following procedure.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 Enter the cc command to change to an active AXSM card for which you will select an SCT.
M8850_LA.8.PXM.a > cc 1
(session redirected)
M8850_LA.2.AXSM.a >
Note In a redundant pair, you must specify the SCT on the active card.
