6 Click on the MTU Ping tab button.
7 Click on the Create button. The MTU Ping (Create) form appears with the General
tab button selected. The form displays information about the service tunnel being
tested and the originating tunnel ID.
8 Configure the parameters for the diagnostic session. Click on the Test Parameters
tab button and enter the MTU value recorded in step 1 for the MTU End Size
(octets) parameter.
9 Run the diagnostic. The MTU Ping increments the datagram size until it fails to
pass through the SDP (service tunnel) data path, in this case, an MTU Ping from
site ID 10.1.200.52/32 to site ID 10.1.200.53/32 using the network in Figure 4-1.
Click on the Results tab to view the list of trace responses. Double-click on a row
in the list to view its details. The number of responses is determined by the
incremental increase in datagram size.
10 Review the diagnostic results and assess whether the configuration meets the
network requirements. Click on the Packets tab button.
a If the Status column displays Response Received for all circuits, the service
tunnel supports the configured frame transmission size for the circuit. Go to
step 9 a ii in General Procedure 4.2.
b If the Status column displays Request Timed Out for any of the circuits, the
transmission failed at that frame size. If the frame size for the failure point
is below the MTU value configured for the service, the packets are truncating
along the service route. Investigate the cause of the truncated packets.
11 If the service problem persists, another type of service problem may be present.
Perform the steps of the troubleshooting workflow in this chapter.
12 If the troubleshooting workflow does not identify the problem with your service,
contact your Alcatel-Lucent technical support representative. See section 1.4 for
more information.
Procedure 4-7 To verify the end-to-end connectivity of a service
using Service Site Ping
1 Choose Tools→Service Test Manager (STM) from the 5620 SAM main menu. The
Manage Tests form appears.
2 Click on the Create button.
Note — You must use the MTU Ping diagnostic to test the service in
both directions for the connection.
