Applying a New Version of an SCT to a Card or Port
The major version number of an SCT file changes when a new parameter is added to an SCT, or when
an existing parameter in deleted from an SCT. Only Cisco can warrant a major version change to an SCT
file. Major version changes are posted in Release Notes for Cisco MGX 8850 and MGX 8830 Software
Version 3 (PXM45/B and PXM1E).
To apply a new major version of an SCT file to a card or port, use the following procedures:
Step 1 Download the new SCT file to your switch, as described in the “Installing SCT Files” section in
Appendix A, “Downloading and Installing Software Upgrades.”
Step 2 Establish a CLI management session at any user access level.
Step 3 Enter the cc command to change to the appropriate card (the card on which you will apply the new SCT).
In the following example, the user will be applying a new SCT to an AXSM card:
D1.8.PXM.a > cc 2
(session redirected)
D1.2.AXSM.a >
Step 4 Enter the setsctver <sctver> command. Replace <sctver> with the new SCT major version number.
D1.2.AXSM.a > setsctver 2
Step 5 In order for the newer version of the SCT to take effect, you must reset the card. On a redundant pair,
enter the switchredcd command to reset the card. On a standalone card, enter the resetcd command.
Step 6 To verify that the new SCT version has been applied to the appropriate card, enter the dspcd command.
To verify that a new port SCT has been associated on the appropriate ports, enter the dspports command.
Displaying the SCT Checksum
To display the latest SCT checksum number, enter the dspsctchecksum command at the appropriate
AXSM card as shown in the following example:
Deleting an SCTs your Network
To delete an SCT file from the switch, use the following procedure:
Step 1 Establish a CLI management session at any user access level.
Step 2 At the PXM prompt, enter the delsct <card type> <sct type> <sctid> <major ver> command, as shown
in the following example:
D1.8.PXM.a > delsct 1 2 00103 00001
