Special Network Interworking PVC Configuration Parameters
You configure a network interworking PVC (FRF.5) the same way as a service 
interworking PVC (FRF.8). The only difference is that you select an LMI profile and 
specify a NNI DLCI for the network interworking PVC.
The following list summarizes the special configuration parameters that are required 
for network interworking PVCs: 
LMI Profile ID — This field, on the FRF.5 tab of the Add PVC dialog box, allows 
you to enable the selected LMI profile. Selecting zero (0), the default value, disables 
FRF.5.
You enable the LMI profile on a per PVC basis instead of on a logical port basis. The 
LMI profile is a temporary instance of LMI that runs across the ATM network 
interworking PVC, and it defines the LMI state for the circuit. The LMI profile is 
required in addition to the LMIs that are defined for the Frame Relay UNI DCE 
logical port endpoints (see “Configuring Link Management for the Frame Relay 
Logical Port” on page 10-41).
Note  – This release supports one predefined LMI profile, which does not contain any 
user-configurable parameters.
