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" on
page 56, 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" on page 67.

Configuring ATM VC Classes
Use the no version to remove the VC class association with the interface. Issuing
the no version causes the router to set the PVC 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.
! Assign VC class dsl-subscriber-class to ATM 1483 subinterface 5/0.100.
host1(config)#interface atm 5/0.100
host1(config-subif)#class-int premium-subscriber-class
host1(config-subif)#exit
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
