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:
Use the hardware trunkidrange <maxTrunkId> | disable command to set
the Truck ID range:.
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:
To change the default VPI range for Virtual Path Connections (VPC) use the
hardware vpcvpirange command:
Note: These changes take effect only after the next reboot of the module
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
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
Command: M15-155s8:/>hardware vpcvpirange
Output: Configured VPC VPI
range VP Switching is disabled
Current VPC VPI range VP Switching is disabled
Command: M15-155s8:/>hardware vpcvpirange <minVpcVpi>
