Verifying VC Classes
To verify successful configuration of VC classes, use the show atm vc EXEC command. Check that the
VC class properties (encapsulation) are inherited by the appropriate PVCs.
Configuring PVC Discovery
You can configure the NRP to automatically discover internal PVCs that are configured on the NSP. The
discovered PVCs and their traffic parameters are configured on the ATM main interface or on the
subinterface that you specify. The NRP Interim Local Management Interface (ILMI) receives the PVC
parameter information from the NSP.
Configuring PVC discovery on subinterfaces allows you to sort PVCs on a per-VP basis. The
subinterface PVC discovery configuration associates all VCs with non-zero VPI values with the
subinterface of the same number. For example, if the NSP reports PVC 2/123, the NRP associates that
PVC with ATM0/0/0.2, and the PVC inherits parameters applied to the subinterface.
To configure the NRP for PVC discovery, complete the following steps beginning in global
configuration mode:
Command Purpose
Step1
Router(config)# vc-class atm name
Creates or selects a map class.
Step2
Router(config-vc-class)# encapsulation aal-encap
[ppp virtual-template number]
Configures the ATM adaptation layer (AAL)
and encapsulation type. Optionally configures
a PVC to use a virtual-template as the default
PPP interface configuration.
Step3
Router(config-vc-class)# exit
Returns to global configuration mode.
Step4
Router(config)# interface atm 0/0/0
Specifies the main ATM interface.
Step5
Router(config-if)# pvc [name] 0/16 ilmi
Configures an ILMI PVC on the main ATM
interface. PVC 0/16 is reserved for the ILMI.
Step6
Router(config-if-atm-vc)# exit
Returns to configuration mode.
Step7
Router(config-if)# atm ilmi-pvc-discovery [subinterface]
Enables PVC discovery on the main interface,
and optionally specifies that discovered PVCs
will be assigned to a subinterface.
