Chapter 8 Permanent Virtual Connections (PVCs and PVPs)

To create a PVC connection, use the pvc setup pp command:

Command:

M15-155s8:/>pvc setup pp <vcl1index> <vcl2index> [<td1> [<td2>]]

Example1:

Setting up a PP PVC between 2 ports on the same module:

 

M15-155s8:/>pvc setup pp 8.1.0.1001 8.2.0.1002 6 2

Example2:

Setting up a PP PVC between 2 ports on different modules but on the

 

same switch:

 

 

M15-155s8:/>On module 8: M15-155s8:/>pvc setup pp 8.1.0.1001

 

9.1.0.1002

6

2

 

M15-155s8:/>On module 9: M15-155s9:/>pvc setup pp 9.1.0.1002

 

8.1.0.1001

2

6

Parameters:

<vcl1index>

 

The first VCL for the PVC connection in the format

 

 

 

<slot.port number.vpi.vci>.

 

<vcl2index>

 

The second VCL for the PVC connection in the format

 

 

 

<slot.port number.vpi.vci>.

 

td1

 

This refers to the transmit traffic descriptor of the first VCL and the

 

 

 

receive traffic descriptor of the second VCL on the PVC

 

 

 

connection.

 

td2

 

This refers to the receive traffic descriptor of the first VCL and the

 

 

 

transmit descriptor of the second VCL on the PVC connection.

 

 

 

Note: if td2 is omitted then it defaults to the same as td1.

Creating a Point-to-Multipoint (PMP) PVC connection

Note: Before you set up a PMP PVC you have to identify the Trunk ID range that can be used by the module that holds the root of the call. Trunk IDs are used for associating different branches of the same PMP PVC call to its root. There may be up to 895 Trunk IDs on each module that holds roots of PMP PVC calls. By default, no Trunk IDs are defined. Refer to Chapter 7, “Managing Module Hardware” for instructions on how to change that definition.

For PMP PVC calls, the optional traffic descriptor parameter indicates the traffic on the forwarding direction, i.e. from the root to the branches. The backward (reverse) direction is always zero.

To set up a PMP PVC between ports on different modules (on the same switch) you must type the command on the CLI of each module. The order of the VCLs should NOT switch places. The root VCL is the first, and the branch VCLs come second.

The command described below will setup a VCL on each <slot.port.vpi.vci> and a PMP PVC connection joins the root to its branches. The PMP PVC connection will be automatically assigned an id.
