Assigning VC Classes to ATM Major Interfaces

class-int
62
Use the no version to remove the VC class association with the data PVC.
See class-vc.
To assign a previously configured VC class to an ATM major interface, you use the class-int
command from Interface 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 interface.
For example, the following commands assign the VC class named dsl-subscriber-class
to an ATM major interface configured on slot 5, port 0.
! Assign VC class dsl-subscriber-class to ATM interface 5/0.
host1(config)#interface atm 5/0
host1(config-if)#class-int dsl-subscriber-class
host1(config-if)#exit
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 53, the
values in a VC class assigned to an ATM major interface have a lower precedence than
both of the following:
Values in a VC class assigned to an individual ATM PVC
Values in a VC class assigned to an ATM 1483 subinterface
This means that if a VC class is assigned to an individual PVC or ATM 1483 subinterface
configured on the major interface, the attribute values configured in the VC class assigned
to the PVC or subinterface override the attribute values configured in the VC class assigned
to the major interface.
For examples that illustrate how precedence levels affect the assignment of VC classes,
see "Precedence Level Examples for Assigning VC Classes" on page 64.
Use from Interface Configuration mode to assign a previously configured VC class to
an ATM major interface.
You must issue the exit command from Interface Configuration mode for the VC class
association to take effect.
Example
host1(config-if)#class-int gold-subscriber-class
host1(config-if)#exit
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.
