Creating P2MP PVCs

There are four steps in creating a P2MP PVC on the M770 ATM switch:

1Create the Traffic Descriptor (TD) that will be used for the PVC

2Set the Trunk ID range for the module

3Limit the Signaling SVC range on the vport(s)

4Create the P2MP PVC.

The next four subsections explain how to setup a P2MP PVC on the M770 ATM switch. In this example, a P2MP PVC will be setup on the M770 between ports 1.1, 2.1 and 3.1 using trunk ID 150 and VPI 0/ VCI 115.

The M770 ATM switch uses the following system to describe a VC. The number, "1.2.0.115:" indicates that there is a VC on slot 1, port 2 using VPI 0 and VCI 115.

Creating a Traffic Descriptor

A Traffic Descriptor must be defined with the service class that will be used to transport the traffic and the bandwidth that is required. The example below shows a cell rate of 4152 cells per second, appropriate for a DS1 (24 DS0s times 173 cps)

Command:

Example:

To determine which td_id is available, type td show to display all defined Traffic Descriptors.

Setting the Trunk ID range for the module

Each P2MP PVC has a manually-assigned Trunk ID. The Trunk ID is used as a unique identifier for the P2MP call on both the ingress module (on which the root of the call is connected), and on the egress modules (on which the leaves of the call are connected). The Trunk ID values that are allowed for use by the P2MP call must be defined on the module. The following example configures the Trunk ID Range for the module from 0 to 200.

Command:

M15-155s8:/>hardware

trunkidrange

<maxTrunkId> disable

Example:

M15-155s8:/>hardware

trunkidrange

200

Parameters

<maxTrunkId>

Maximum trunk ID for P2MP PVCs on all ports of the module

Limiting the Signaling SVC range for the virtual port

Before a VCI may be used for a PVC, the signaling SVC range on that vport must be limited to prevent this VCI from being used by an SVC. In this example, we are using the VCIs 114 and 115, so we will limit the signaling SVC range to VCI 100

Command: M15-155s8:/>vport set vcirange <vport id> <range>
