Assigning VC Classes to Static ATM 1483 Subinterfaces

To assign a previously configured VC class to a static ATM 1483 subinterface, you use the class-int command from Subinterface Configuration mode. Issuing this command applies the set of attributes in the specified VC class to the ATM data PVCs statically or dynamically created on this subinterface.

For example, the following commands assign the VC class named premium-subscriber-class to an ATM 1483 subinterface configured on slot 5, port 0, subinterface 100.

For those attributes that you do not explicitly specify for an ATM PVC, the router applies the values specified in the VC class. As explained in Precedence Levels, the values in a VC class assigned to an ATM 1483 subinterface take precedence over the values in a VC class assigned to an ATM major interface, but have a lower precedence than the values in a VC class assigned to an individual ATM PVC.

This means that if a VC class is assigned to a PVC configured on the subinterface, the attribute values configured in the VC class assigned to the individual PVC override the attribute values configured in the VC class assigned to the subinterface.

For examples that illustrate how precedence levels affect the assignment of VC classes, see Precedence Level Examples for Assigning VC Classes.

class-int

• Use from Subinterface Configuration mode to assign a previously configured VC class to a static ATM 1483 subinterface.
• You must issue the exit command from Subinterface Configuration mode for the VC class association to take effect.
• Example

  host1(config-subif)#class-int silver-subscriber-class

  host1(config-subif)#exit

• Use the no version to remove the VC class association with the subinterface. Issuing the no version causes the router to set the VC attributes to their systemwide default values, or to the values set in the associated VC class with the next highest order of precedence.
• See class-int.
