If the If the CLI IP ping fails, the two sites do not have IP connectivity. Go
to step 5.
Use the CLI to verify that the IP address of the destination site is in the routing table
for the originating site by entering:
show router route-table ↵
If the IP address for the destination site is not in the routing table for the originating
site, there is an L3 or L2 problem.
i Verify that the appropriate protocols are enabled and operational on the two
sites.
ii Verify the administrative and operational states of the underlying L2
equipment, for example, ports and cards.
iii Implement and verify the solution for the service problem.
•
If the problem no longer exists on the service, you have completed the
troubleshooting workflow for services. Disable the OAM diagnostics to
conserve system resources. See the 5620 SAM User Guide.
•
If the service problem persists, another type of problem may exist on your
service. Go to section 4.2 and repeat the troubleshooting workflow. If the
troubleshooting workflow does not identify the problem with your service,
contact your Alcatel technical support representative. See section 1.4 for
more information.
Enable the OAM diagnostics for the service. See the 5620 SAM User Guide.
Open the Tunnel Ping configuration form and clear the results from the previous
diagnostic session, if any.
Note — You must use the Tunnel Ping diagnostic to test the service in
both directions for the connection.
Configure the parameters for the diagnostic session as follows.
•
Return Tunnel ID parameter must specify the return tunnel because the tunnels
are unidirectional
•
Forwarding Class parameter must specify the forwarding class for the service
tunnel. Make sure that the forwarding classes for the service tunnels map to the
QoS parameters configured for subscriber services, such as VLL.
•
Interval parameter must send multiple probes
Run the diagnostic. Figure 4-13 shows the diagnostic configuration associated with
a Tunnel Ping from site ID 10.1.200.51/32 to site ID 10.1.200.53/32 using the
network in Figure 4-1.
