Chapter 9 Switch Operating Procedures
Configuring VPI and VCI Ranges for SVCs and SPVCs
Configuring VPI and VCI Ranges for SVCs and SPVCs
When you add a partition to a port, you define the minimum and maximum VPIs and VCIs for that port.
These VPIs and VCIs become available for all services unless you make additional configuration
changes. If this configuration is acceptable for your installation, you can skip this section. You are not
required to configure VPI and VCI ranges for SVCs and SPVCs.
The Cisco MGX switches allow you to define the minimum and maximum values for the following
parameters:
• SVCC VPIs
• SVCC VCIs
• SPVC VPIs
To configure VPI and VCI usage for connections on a specific port, use the following procedure.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 To display a list of PNNI ports, enter the dsppnports command.
Step 3 Enter the following command to bring down the PNNI port you want to configure:
mgx8830a.1.PXM.a > dnpnport <portid>
A PNNI port is automatically brought up when you add it. You must bring down the port before you can
change the port range. Replace <portid> using the format slot:bay.line:ifNum. Table 9-1 describes these
parameters.
Step 4 Enter configure the port range, enter the following command:
mgx8830a.1.PXM.a > cnfpnportrange <portid> [-minsvccvpi <min-svcc-vpi>]
[-maxsvccvpi <max-svcc-vpi>] [-minsvccvci <min-svcc-vci>] [-maxsvccvci <max-svcc-vci>]
[-minsvpcvpi <min-svpc-vpi>] [-maxsvpcvpi <max-svpc-vpi>]
The only required parameter for this command is the <portid> parameter, but the command serves no
purpose if you enter it without options. If you include some options with the command and omit others,
the omitted options remain set to the last configured values. Table 9-25 lists and describes the options
and parameters for this command.
