Configuring CBX or GX Logical Ports
Setting Logical Port Attributes
Setting Logical Port Attributes
When you configure logical ports, the Add Logical Port dialog box (Figure 3-5 on
page 3-8) contains a variety of parameters that you must specify. To configure the
ATM logical port parameters, see the following tabs:
General — Displays general logical port attributes, including Admin Status,
Connection ID, Redirect PVC Delay Time, Bulk Statistics settings, Resource
Partitioning and more. See “General Attributes” on page 3-16 to set these attributes.
Administrative — Displays administrative attributes, including committed
information rate (CIR) Oversubscription, Shaping Type, Bandwidth, and Path Trace.
See “Administrative Attributes” on page 3-20 to set these attributes.
ATM — Displays the ATM attributes, including the Number of Valid Bits in VCI,
Number of Valid Bits in VPI, and ATM Protocol. You can also enable or disable the
Call Admission Control (CAC) or usage parameter control (UPC) functions from this
tab. See “ILMI/OAM Attributes” on page 3-34 to set these attributes.
ILMI/OAM — Displays the ILMI/OAM attributes, which allow you to fine-tune your
ATM service. See “ILMI/OAM Attributes” on page 3-34 to set the following
attributes:
ILMI – A Management Information Base (MIB) that provides status and
communication information to ATM UNI devices and provides for a port
keep-alive protocol. This selection also provides an option to configure the
traffic characteristics for the Interim Local Management Interface (ILMI) control
channel.
OAM – A parameter that enables the logical port to generate Operations,
Administration, and Maintenance (OAM) alarms.
CES Parameters — Displays the circuit emulation attributes, such as clock mode,
buffer size, cell jitter and loss, conditioning modes, and more. See “CES Attributes”
on page 3-37 to set these attributes.
Traffic Descriptors — Displays the Traffic Descriptors attributes, which allow you to
configure ATM traffic descriptors for the trunk logical ports. See “Traffic Descriptor
Attributes” on page 3-41 to set these attributes.
VPI Range — Displays the VPI Range attributes, which allow you to specify the
range of VPIs that can be created over an OPTimum trunk. These options work in
conjunction with IP’s label switched path (LSP), a feature that is used to switch IP
traffic through a Lucent cloud using ATM VP switching. You also use this option to
configure the OPTimum trunk to handle virtual path connections (VPCs). See
“OPTimum Trunk VPI Range Attributes” on page 3-45 to set these attributes.
ATM FCP — Displays the ATM FCP attributes, which allow you to configure logical
ports for the CBX 3500 and CBX 500 ATM Flow Control Processor (FCP). See “ATM
FCP Attributes” on page 3-49 for information about ATM FCP.
