Choose L2 Service→Create MAC Ping from the Create contextual menu. The MAC Ping (Create) form appears.
|
4 |
Clear the results from the previous diagnostic session from the Results tab, if necessary.
Note: You must use the MAC Ping and MAC Trace diagnostic to test the service in both directions for the connection.

You can target the MAC broadcast address of FF-FF-FF-FF-FF-FF in the data plane to flood the service domain and receive a response from all operational service access ports. Enter the service ID for the VPLS or VLL service between the sites, and the sites you want to ping, in this case, from site ID 10.1.200.51/32 to site IDs 10.1.200.52/32 and 10.1.200.53/32 using the network in
Figure 6-1, Sample network.
Click on the Results tab to view the list of ping responses. Double-click on a row in the list to view its details.

You can target the specific MAC address of a service site. Enter the target MAC address of the specific site in the service that you want to ping, in this case, from site ID 10.1.200.51/32 to site ID 10.1.200.52/32 using the network in
Figure 6-1, Sample network.

Review the results and assess whether the configuration meets the network requirements.
In particular, review the results in the Return Code column. The table below lists the displayed messages. Table 6-1: MAC Ping OAM diagnostic results

Displayed message |
Description |
|
notApplicable (0) |
The OAM diagnostic message does not apply to the OAM diagnostic performed. |
|
fecEgress (1) |
The replying router is an egress for the FEC.
The far-end egress point exists and is operating correctly. No action required. |
|
fecNoMap (2) |
The replying router has no mapping for the FEC. |
|
notDownstream (3) |
The replying router is not a downstream router. |
|
downstream (4) |
The replying router is a downstream router, and the mapping for this FEC on the router interface is the specified label. |
|
downstreamNotLabel (5) |
The replying router is a downstream router, and the mapping for this FEC on the router interface is not the specified label. |
|
downstreamNotMac (6) |
The replying router is a downstream router, but it does not have the specified MAC address. |
|
downstreamNotMacFlood (7) |
The replying router is a downstream router, but it does not have the specified MAC address and cannot flood the request to other routers. |
|
malformedEchoRequest (8) |
The received echo request is malformed. |
|
tlvNotUnderstood (9) |
One or more TLVs were not understood. |

Choose L2 Service→Create MAC Trace from the Create contextual menu. The MAC Trace (Create) form appears.
|
9 |
Configure the required parameters for the diagnostic session and run the diagnostic. A MAC Trace shows the path, protocol, label, destination SAP, and hop count to the location of the destination MAC. Enter the service ID for the VPLS or VLL service between the sites, and the sites you want to trace, in this case, from site ID 10.1.200.51/32 to site IDs 10.1.200.52/32 and 10.1.200.53/32 using the network in
Figure 6-1, Sample network .
Click on the Results tab to view the list of trace responses. Double-click on a row in the list to view its details.
