To apply a changed SCN, i.e., to trigger sending a DSC message
to any matching CM with a service flow whose SCN-defined
QoS parameter set is out-of-date:
Note: If the MAC address is not specified, then DSC messages
are sent to all CMs using the specified SCN, updating the QoS
parameter sets of all those modems.
configure qos-sc name <service class name> apply-
update [<mac-addr>]
To show the approximate number of service flows that would
be affected by an SCN parameter change and the apply-
update command:
show cable modem qos-sc name <scn name> | include
Found
To show all the CMs using a particular SCN:
show cable modem qos-sc name <scn name>
To show the QoS parameter settings for this particular CM:
show cable modem qos-sc cm-mac <cm mac address>
To show which SCNs have service flows with updates that are
still pending:
show cable modem qos-sc update-pending [name <scn
name>]
Sample Show Commands
In the following example the modems using service class GoldDn are given a maximum sustained downstream rate of 1
