3. In the LPort Type field, select ATMoMPLS Trunk from the pull-down list. This is
the only available LPort Type if an ATMoMPLS UNI or ATMoMPLS NNI feeder
logical port has been created on the physical port. All non-ATM-related
parameters are disabled.
When you configure logical ports, the Add Logical Port dialog box contains a
variety of parameters that you must specify. During this procedure, use the various
tabs in the Add Logical Port dialog box to configure General, Administrative,
QoS, and Traffic Descriptors parameters for the ATMoMPLS Trunk logical port.
For ATMoMPLS Trunk logical ports, the next available unique Trunk ID is
assigned by the NMS based on the trunk ID bits in the feeder logical port
configuration. You can configure the Trunk ID value if desired using the General
tab.
Refer to the following sections for information about the attributes:
– “ATMoMPLS Trunk Logical Port General Attributes” on page 8-35
– “ATMoMPLS Trunk Logical Port Administrative Attributes” on page 8-37
– “ATMoMPLS Trunk Logical Port QoS Attributes” on page 8-40
– “ATMoMPLS Trunk Logical Port Traffic Descriptor Attributes” on page 8-42
4. In the Add Logical Port dialog box, click OK to add the ATMoMPLS Trunk
logical port.
If bi-directional APS is enabled on the physical port, the logical port is created on both
physical ports of the APS pair.
ATMoMPLS Trunk Logical Port General Attributes
For ATMoMPLS Trunk logical ports, you must configure the Trunk ID field in the
General tab. The next available unique Trunk ID is assigned by Navis EMS-CBGX
based on the trunk ID bits in the feeder logical port configuration.
The Trunk ID bits field contains a read-only value that was configured during the
definition of the ATMoMPLS UNI or ATMoMPLS NNI feeder port.
