Configuring ATM PVCs
About the PVC Tabs
About the PVC Tabs
When you configure a PVC, the dialog box provides detailed parameters that you need
to specify for each endpoint. During this procedure, you use the following tabs on the
Add PVC dialog box (see Figure 10-3).
Administrative — Defines administrative information, such as circuit name,
administrative status, and circuit type. See “Administrative Attributes” on page 10-17.
Traffic Type — Defines the traffic descriptor (TD) settings for forward and reverse
traffic. See “Traffic Type Attributes” on page 10-22.
User Preference — Defines PVC features that deal with port congestion and traffic
policing. See “User Preference Attributes” on page 10-26.
Traffic Mgmt. — Defines UNI 4.0 signaling frame discard features for the forward
and/or backward direction. The method of achieving frame discard depends on the
implementation of early packet discard/partial packet discard (EPD/PPD) in your
network. Your equipment must support frame discard. Also defines the ATM Forum
TM 4.0 Extended QoS Parameters. This selection enables you to define cell delay
variation (CDV) and cell loss ratio (CLR) in the forward and reverse direction. See
“Traffic Management Attributes” on page 10-31.
NDC — Defines CBX 500 and GX 550 Network Data Collection (NDC) functions,
which can detect any violation of PVC service subscription parameters and establish
trends in network traffic patterns and loads. See the Switch Diagnostics User’s Guide
for CBX 3500, CBX 500, GX 550, and B-STDX 9000 for information about NDC functions.
Accounting — Use the optional Accounting tab to configure NavisXtend Accounting
Server parameters for this circuit. For more information, see the NavisXtend
Accounting Server Administrator’s Guide.
Path —The Path tab enables you to manually define a circuit path and the OSPF
algorithm’s circuit routing decisions. For more information, see “Manually Defining
the Circuit Path” on page 10-68.
FRF.5 — The FRF.5 tab enables you to define network interworking PVC
configuration parameters, including the LMI Profile ID and NNI DLCI. This tab is
applicable only for a network interworking PVC containing one Frame Relay and one
ATM endpoint.
Pwe3 — The Pwe3 tab enables you to define Pseudo Wire Edge-to-Edge Emulation
(PWE3) standards on a circuit. See “Configuring a PWE3 Circuit” on page 9-64 for
more information on the fields on this tab.
Continue with the following sections to configure these parameters.
