The Configured version of the Service Class Template(SCT)
file. This version applies to both the card SCT and the port
SCT files in a service module.
The port SCT files are specified while provisioning a port using
the caviFileId field in the CISCO-WAN-VIRTUAL-IF-MIB.my MIB.
The card SCT file is specifed in this MIB using the
cwmIngressSCTFileName object.
The configured version of the SCT does not take effect until
the service module is rebooted. However, graceful invocation
of a new SCT version can be achieved by using redundant service
modules. The configured SCT version is first applied on a standby
service module by rebooting it. When the standby reboots, it
comes up with the configured SCT version. Thereafter a switchover
can be performed, making the standby SM take over as active.
