Configuring ATM Over MPLS Trunks
Configuring Feeder Logical Ports
Administrative Attributes
For ATMoMPLS UNI/NNI feeder logical ports, you need to assign a minimal amount 
of bandwidth to the feeder logical port for control data. This is done by completing the 
Bandwidth (Kbps) Allocated field in the Administrative tab of the Add Logical Port 
dialog box (Figure 8-11). 
Network Overflow Specifies how SVC traffic originating from this logical port is 
managed during trunk overflow or failure conditions. This 
feature is used with VNN VPN. 
Public – (default) Routes SVCs originating from this port over 
dedicated VNN VPN trunks. However, in the event of failure, 
the customer’s traffic is allowed to run over common trunks 
(shared by a variety of different customers).
Restricted – Uses SVCs originating from this port only for 
dedicated VNN VPN trunks. A customer using this mode must 
purchase redundancy trunks to be used in the event of outages 
or other trunk failures.
Template Select the check box to save these settings as a template to 
configure another logical port with similar options. 
Clear the box (default) if you do not wish to save the settings as 
a template.
