Precedence Levels for Static PVCs

For PVCs that are statically created, the router determines the PVC attribute values according to the following precedence levels, in order from highest precedence to lowest precedence:

1. The most recent explicitly set value for a PVC attribute always has the highest precedence and overrides any settings in the VC class. Explicitly set values for PVC attributes are those values configured with the CLI (by using the atm pvc command or commands in ATM VC Configuration mode), SNMP, or assigned by RADIUS.
2. If an attribute value is not explicitly specified, the router takes the value for that attribute from the assigned VC class, in the following order of precedence:
   1. Attribute value specified in the VC class assigned to this PVC
   2. Attribute value specified in the VC class assigned to the ATM 1483 subinterface on which this PVC is created
   3. Attribute value specified in the VC class assigned to the ATM major interface on which this PVC is created
3. If no PVC attributes are explicitly specified and no VC class assignments exist, the router applies the default values for the commands listed in Table 9. For information about the default value for each command, see the command descriptions in Configuring VC Classes.
