Creating PVPs

 

 

The next three subsections explain how to setup a PVP on the M770 ATM switch.

Define a VPI range for VP switching

By default, all VPIs on a module are used for VC switching and VP switching is disabled. The following command defines the range of VPIs that will be used for Virtual Path (VP) switching for all ports on the module. The command must be executed on all modules that will perform VP switching. For our examples, we need to configure the VPI range 5 - 7 for VP switching .

Command:

M15-155s1:/>hardware vpcvpirange <minVpcVpi>

Example 1:

Module 1

M15-155s1:/>hardware vpcvpirange 5

Example 2

Module 1

M15-155s1:/>hardware vpcvpirange 5

 

Module 2

M15-155s2:/>hardware vpcvpirange 5

Parameters

<minVpcVpi>

Minimum number for Vpc Vpi for all ports on the module.

 

 

Maximum Vpc Vpi is set to maximum Vpi according to

 

 

vpivcibits set in the command "hardware vpivcibits"

Note: You must reset each module in order for the change to take place.

After resetting the module, you can verify that the VPIs have been reserved for VP switching by typing in the command, vport show vpivciranges.

Define the VPI range to be used for Signaled VPs

In step 1, all of the VPIs reserved for VPs are automatically reserved for Signaled VPs. Before a VPI may be used for a PVP, the signaling VP range on that vport must be limited to prevent this VPI from being used by a Signaled VP.

There are some rules to remember in defining the range for Signaled VPs:

1At least one of the VPIs defined in Step 1 MUST be reserved for Signaling VPs.

2In defining the range for Signaled VPs, the lower bound MUST be the minimum VPI defined in the Step 1.

In this example, we are using VPIs 6 and 7, so we will limit the signaling VPIs to just VPI 5. This meets the criteria defined above.

Command:

M15-155s1:/>vp set sigvpcvpirange <root vport id> [<range>]

Example 1:

Module 1

M15-155s1:/>vport disable

1.1.0

 

 

M15-155s1:/>vport

disable

1.2.0

 

 

M15-155s1:/>vport

set sigvpcvpirange 1.1.0 [5..5]

M15-155s1:/>vport set sigvpcvpirange 1.2.0 [5..5]

M15-155s1:/>vport enable 1.1.0

M15-155s1:/>vport enable 1.2.0
