To test the configuration

1.Start a telnet session between the client and server.

2.Check the statistics on Nokia Platform A and Nokia Platform B

a.Click Interfaces under Configuration > Interface Configuration in the tree view.

b.Click on the link for ser-s3p1 in the Physical column.

c.Click on the Interface Statistics link.

d.Scroll down to view statistics for Queue Class wan_1_ef.

You should see values other than zero on both Nokia Platform A and Nokia Platform B for the Packets Passed and Bytes Passed counters in the Expedited Forwarding row.

3.Use the telnet session to generate traffic, and then check each Nokia Platform’s interface statistics.

a.Click Interfaces under Configuration > Interface Configuration in the tree view.

b.Click on the link for ser-s3p1 in the Physical column.

c.Click on the Interface Statistics link.

d.Examine the statistics for input and output traffic and compare them to the statistics for Expedited Forwarding traffic.

4.Start an ftp session to create heavy (non-telnet) background traffic over the WAN. Note that the telnet session remains responsive. Use a text editor to examine a file.

5.Save the QoS routing configuration (See Step 1 in the instructions for how to configure this example), and restore the non-QoS configuration. Compare the difference in responsiveness when there is heavy WAN traffic both with and without QoS routing.
