Chapter 7 Switch Operating Procedures
Configuring VPI and VCI Ranges for SVCs and SPVCs
The Cisco MGX 8850 and Cisco MGX 8950 switches allow you to define the minimum and maximum
values for the following connections:
• 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 Use the following command to bring down the PNNI port you want to configure:
popeye2.7.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 7-1 describes these
parameters.
Step 4 To configure the port range, enter the following command:
popeye2.7.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 7-35 lists and describes the options
and parameters for this command.
