Verifying PNNI Communications
Replace <ifNum> with the number of the interface whose connection test results you want to display.
Replace <vpi> with the VPI of the connection whose test results you want to display. Replace <VCI>
with the VCI of the connection whose test results you want to display. If you want to specify the number
of tests whose results you want to display, enter the options -num keyword, followed by the number of
consecutive connections whose test results to display. You display test results for up to 10 connections.
Note The dspchantest command displays the results of the last test run on the specified number of
connections, regardless of whether it was a tstcon or the tstdelay test.
Note If you do not specify the -num <iterations> option, the test display only the results for the last test that
was run on the specified connection.
Note Enter the dspcons command to obtain the interface number, VPI, and VCI of a connection.
In the following example, the user displays the results for the last test that was run on the connection on
port 1, VPI 101, VCI 101.

Verifying PNNI Communications
After setting up trunks or when problems occur, use the procedures in this section to determine if PNNI
is operating. The next section describes how to verify PNNI communications on a single trunk. The
following section describes how to verify PNNI communications between two nodes, which can be
separated by multiple PNNI links.
Verifying PNNI Trunk Communication
After you configure both ends of a PNNI trunk, it should be ready to support SVCs and any SPVCs or
SPVPs that are configured. To verify that the trunk is functioning, use the following procedure.
Step 1 Establish a CLI session using a user name at any access level.
If you are configuring a point-to-point (P2P) or point-to-multipoint (P2MP) connection where both ends
of the trunk are connected to Cisco MGX 8850 (PXM1E/PXM45), Cisco MGX 8950, or Cisco MGX
8830 switches, you can start the CLI session at either end of the connection.
Step 2 If you do not know the line number you are validating, you can view the port and line numbers by
entering the dsppnports command on the active PXM card.
