2. Check whether a loop has formed or whether there are user attacks on the port that the user's
MAC address has drifted to. If a loop has formed, disconnect it. If the port that the MAC
address has drifted to is being attacked, deactivate the port initiating the attacks. Then,
check whether the service is restored.
l If the service is restored, go to Step 7.
l If the service is not restored, go to Step 5.
Step 5 Check whether a BRAS MAC address drift has occurred on the MA5612.
1. Run the display location mac-addr command to check multiple times (recommended: three
times) whether a BRAS MAC address has drifted away from the port that originally learned
it.
l If the BRAS MAC address has drifted, go to Step 5.2.
l If the BRAS MAC address has not drifted, go to Step 6.
NOTE
l The mac-addr parameter in the command indicates the BRAS's MAC address.
l The F/S/P parameter in the query result indicates the uplink port that learned the BRAS MAC
address. Normally, the port displayed in the query result is the uplink port on the MA5612
connected to the BRAS. If the displayed port is not the uplink port, the BRAS MAC address has
drifted.
2. Check whether a loop has formed or whether there are user attacks on the port that the user's
MAC address has drifted to. If a loop has formed, disconnect it. If the port that the MAC
address has drifted to is being attacked, deactivate the port initiating the attacks. Then,
check whether the service is restored.
l If the service is restored, go to Step 7.
l If the service is not restored, go to Step 6.
Step 6 Record the results of the preceding steps in a fault report (see Fault Report Form), fill out the
entire form, and then submit it to Huawei for technical support (see Contacting Huawei for
Assistance).
Step 7 End.

4.2 Troubleshooting the Multicast Service
This chapter describes how to troubleshoot common multicast service faults.
4.2.1 Failure to Go Online of a Multicast User
This topic describes how to troubleshoot the fault when a multicast user fails to order any
programs because the multicast user fails to go online (the queried user status is offline or
block on the MA5612). When such a fault occurs, locate the fault according to the following
procedure.
Location Method
When a multicast user is blocked, run the undo igmp user block command to unblock the user.
When a multicast user is offline, enable the MA5612 debugging function and locate the fault
according to whether the MA5612 receives the report packet from the multicast user.
