Selecting a Port SCT
A port SCT defines queue parameters that apply to egress queues on a port. You can use the same port
SCT for multiple ports. 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.
To select an SCT for an ATM port, enter the addport command as described in the “Adding ATM Ports”
section on page 3-27.
For information on managing port SCTs on AXSM cards, refer to “Managing Card SCTs” section on
page 4-4.
For informationdownloading, installing, and registering SCTs, see the Cisco MGX 8800/8900 Series
Configuration Guide, Release 5.2.
Note A port SCT must reside in your PXM F:/SCT directory before you can select it for a port.
Note An SCT must be registered before you can select it for a card or port. The exception to this requirement
is the default SCT (SCT 0), which is permanently registered.
Changing a Port SCT
To change the SCT assigned to a port, enter the cnfport command as follows:
M8850_SF.5.AXSM.a > cnfport -if < ifNum > -sct < sctID >
Replace <ifNum> with the number of the logical interface (port) whose SCT you want to change.
Replace <sctID> with the number of a service class template (SCT) you want the port to use, in the range
from 0 through 255.
