Example 1 and Example 2 illustrate the effect of precedence levels when you assign the
VC class my-premium-class to an individual PVC with VCD 200, VPI 0, and VCI 200.
Example 3 illustrates how using the atm pvc command affects VC class assignment.
Finally, Example 4 illustrates how modifications to a VC class affect PVC attributes
applied through RADIUS.

Example 1: Explicitly Changing the Service Category

Explicitly specified attribute values take precedence over attribute values specified in a
VC class. As a result, the following commands cause the router to use the most recent
explicitly specified value, UBR with a PCR of 200 Kbps, as the service category for this
PVC instead of the service category specified in my-premium-class, CBR with a PCR of
200 Kbps. The router takes the values for the other attributes from the VC class
my-premium-class.
host1(config)#interface atm 2/0.200
host1(config-subif)#pvc 200 0/200
host1(config-subif-vc)#ubr 200
host1(config-subif-vc)#class-vc my-premium-class
host1(config-subif-vc)#exit
The following commands change the service category for the PVC to VBR-RT because
this is the most recent explicitly specified value for this attribute. The router takes the
values for the other attributes from the VC class my-premium-class, which is still assigned
to the PVC.
host1(config)#interface atm 2/0.200
host1(config-subif)#pvc 200 0/200
host1(config-subif-vc)#vbr-rt 200 150 200
host1(config-subif-vc)#exit
The following commands cause the router to retain the VBR-RT service category for the
PVC because it is still the most recent explicitly specified value for this attribute. The
router takes the values for the other attributes from the VC class my-premium-class.
host1(config)#interface atm 2/0.200
host1(config-subif)#pvc 200 0/200
host1(config-subif-vc)#class-vc my-premium-class
host1(config-subif-vc)#exit

Example 2: Changing the Encapsulation Method in the VC Class

The following commands change the value for the encapsulation method in the VC class
my-premium-class from aal5autoconfig to aal5snap. As a result, the router now uses
aal5snap instead of aal5autoconfig as the encapsulation method for the PVCs to which
this VC class is assigned.
host1(config)#vc-class atm my-premium-class
host1(config-vc-class)#encapsulation aal5snap
host1(config-vc-class)#exit
