Use the results from the MAC Ping and MAC Trace diagnostics to choose one of the
following options:
a If the MAC Ping and MAC Trace diagnostics returned the expected results for
the configuration of your network:
i Measure the frame transmission size on all objects associated with the
service such as the service sites, access and network ports, service
tunnels, and circuits. See Procedure 4-5.
ii Review the ACL filter policies to ensure that the ACL filter for the port is
not excluding packets that you want to test. See Procedure 4-10.
iii Verify the QoS configuration.
You have completed the workflow for troubleshooting services. Contact
your Alcatel technical support representative if the problem persists. See
section 1.4 for more information.
b If the MAC Ping and MAC Trace diagnostics did not return the expected results
for the configuration of your network:
i Verify the end-to-end connectivity on the service using the Circuit Ping
diagnostic. See Procedure 4-6.
ii Verify the end-to-end connectivity on the service tunnel using the Tunnel
Ping diagnostic. See Procedure 4-7.
iii Verify the end-to-end connectivity of an MPLS LSP using the LSP Ping
diagnostic. See Procedure 4-8.
You have completed the workflow for troubleshooting services. Contact
your Alcatel technical support representative if the problem persists. See
section 1.4 for more information.
c If the MAC Ping diagnostic returned the expected results for the configuration
of your network, and the MAC Trace diagnostic did not return the expected
results for the configuration of your network:
i Verify that the correct service tunnels are used for the service.
ii Correct the service tunnel configuration, if required.
iii Verify if the service problem still exists. If the service problem no longer
exists, you have completed the workflow for troubleshooting service. If
the service problem still exits, go to step 9.c.iv.
iv Review the route for the MPLS LSP using the LSP Trace OAM diagnostic.
(For MPLS encapsulation, only.) If the LSP Trace results do not meet the
requirements of your network, review the resource availability and
configurations along the LSP expected routes. See Procedure 4-9.
You have completed the workflow for troubleshooting services. Contact
your Alcatel technical support representative if the problem persists. See
section 1.4 for more information.
