Cisco MGX 8800/8900 Series Software Configuration Guide
Release 5.1, Part Number OL-6482-01, Rev. A0, January 25, 2005
Chapter 9 Switch Operating Procedures
Managing Path and Connection Traces
Step 5 Enter the following command to bring up the PNNI port you just configured:
mgx8830a.1.PXM.a > uppnport <portid>
Replace <portid> using the format slot:bay.line:ifNum. Table 9-1 describes these parameters.
Step 6 To display the PNNI port range for a port, enter the following command:
mgx8830a.1.PXM.a > dsppnportrange <portid>
After you enter this command, the switch displays a report similar to the following example:
mgx8830a.1.PXM.a > dsppnportrange 1:2.1:2
minSvccVpi: 0 maxSvccVpi: 4095
minSvccVci: 35 maxSvccVci: 65535
minSvpcVpi: 1 maxSvpcVpi: 4095
Managing Path and Connection Traces
Cisco MGX switches support the following traces:
• path traces — the trace occurs only during call setup. Therefore, tracing is enabled before call set
up then actually occurs while PNNI routes the connection. The applicable connections are SPVCs,
SPVPs, SVCs, or SVPs.
• connection traces — the trace occurs for a call that has already been routed. You can trace the route
of existing SPVCs and SVCs.
For more information about enabling path and connection traces, refer to the Cisco MGX 8800/8900
Series Command Reference, Release 5.1.
Displaying Path and Connection Traces
There are several commands that allow you to display trace information about a connection. By entering
these commands at the slave end of the connection, you can determine the path taken by a connection.
Table 9-26 describes these commands.
max-svcc-vci Maximum VCI value for SVCC.
Range: 32 to 65535.
Default = 65535.
min-svpc-vpi Minimum VPI value for SVPC.
Range: 1to4095.
Default = 1.
max-svpc-vpi Maximum VPI value for SVPC.
Range: 1to4095.
Default = 4095.
