General Attributes
For ATMoMPLS UNI/NNI feeder logical ports, you need to configure the Trunk ID
bits field. Enter a value to set the number of bits in the header used to identify the
Trunk ID. The default value is set to 3 (corresponding to a maximum number of 8
unique trunk IDs) for ATMoMPLS UNI or 5 (corresponding to a maximum number of
32 unique trunk IDs) for ATMoMPLS NNI. The range for the trunk ID bits is 1-3 for
ATMoMPLS UNI and 1 to 5 for ATMoMPLS NNI. The General tab in the Add
Logical Port dialog box is shown in Figure 8-10.
