When the you wish to set a P2MP PVC, you need to assign trunk ID to the P2MP call 
manually. 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). Trunk IDs are defined on a 
module basis using the following commands. They are used in the PVC setup, for 
more details see Chapter 8, “Permanent Virtual Connections (PVCs and PVPs)”.
Use the 

hardware trunkidrange

 command to display the current configuration 

of Trunk ID range:

Use the 

hardware trunkidrange <maxTrunkId> | disable

 command to set 

the Truck ID range:.

Changes to the Trunk ID range applies to all ports of the module, and they 

take effect only after the next reboot of the module.

When the user wishes to configure Virtual Path (VP) switching, the VPI range has to 
be set to meet this need. By default, all VPIs are used for VC switching, therefore, 
the default configuration is:

To change the default VPI range for Virtual Path Connections (VPC) use the 

hardware vpcvpirange

 

command:

These changes take effect only after the next reboot of the module
