5.2 Troubleshooting Multicast Service
This section describes how to troubleshoot common faults in the multicast service
Prerequisites
The ONU and the OLT must communicate with each other normally. If a fault occurs in
communication between the ONU and the OLT, all the services of the ONU are interrupted.

NOTE
l The mac-addr parameter in the command indicates the user's MAC address. For modem dialup,
the user's MAC address is the MAC address of the modem. For PC dialup, the user's MAC address
is the MAC address of the PC.
l The F/S/P parameter in the query result indicates the service port that learned the user's MAC
address. Normally, the port displayed in the query result is the service port of the user. If the
displayed port is not the service port of the user, the user's MAC address has drifted.
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
l If the service is not restored, go to
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
l If the BRAS MAC address has not drifted, go to
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 ONU connected
to the BRAS. If the displayed port is not the uplink port, the BRAS MAC address has drifted.
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
