Managing Trunk ID range for P2MP PVCs

Chapter 7 Managing Module Hardware

Managing Trunk ID range for P2MP PVCs

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:

Command: M15-155s8:/>hardware trunkidrange

Output:	Allowed	reserved	Trunk	Id	range:	0..895
	Configured reserved Trunk				Id range:	0..0
	Current	reserved	Trunk	Id	range:	0..0

Use the hardware trunkidrange <maxTrunkId> disable command to set the Truck ID range:.

Command: M15-155s8:/>hardware trunkidrange <maxTrunkId> disable

Parameters: <maxTrunkId>	Maximum trunk ID for P2MP PVCs on all ports of the module
disable	The trunk ID reservation will be disabled after the next reboot,
	i.e., the new range will be 0..0

Note: 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.

Managing VPI range for VP switching

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:

Command:	M15-155s8:/>hardware vpcvpirange
Output:	Configured VPC VPI	VP	Switching is disabled
	range
	Current VPC VPI range	VP	Switching is disabled

To change the default VPI range for Virtual Path Connections (VPC) use the hardware vpcvpirange command:

Command: M15-155s8:/>hardware vpcvpirange <minVpcVpi>

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