Fault
Scope
ONU to

terminal
To facilitate fault report, save the results of the following steps.
Procedure
Step 1 On the ONU, run the display igmp user user-index command to query the multicast user status
(State).
l If State is block, the multicast user is blocked. In this case, run the undo igmp user block
l If State is offline, go to
Step 2 Order a program and check whether the user can go online.
l If the user can go online, go to
l If the user fails to go online, go to
Step 3 Enable the ONU debugging function and collect information as follows:

Judgment Criterion
The ONU does not receive
the report packet and all
users in the MVLAN fail to
go online.
The ONU does not receive
the report packet and a
single user fails to go
online.
NOTE
Faults can be located according to specific scenarios because fault scopes are different for deployment and
routine operation and maintenance.
l If the fault occurs during deployment, check initial configurations of the hardware and the software.
l If a multicast user fails to go online during O&M, check only the hardware because the software
configuration of a user is generally not modified in this scenario. Hence, if the status of a user changes
from normal to abnormal, it is generally caused by hardware failures. If a multicast link failure occurs
after a new user is added or an existing user is modified, check whether the configuration is correct.
CAUTION
command to unblock the user. Then, go to
NOTE
If you need to block a multicast user from watching programs temporarily without deleting the user (for
example, when the user owes charges), run the igmp user block command to block the user. When the
user is blocked, the ONU forces the user to go offline from the current program. In addition, the ONU
rejects the user from ordering programs until the user is unblocked.
Enable the function of multicast user monitoring.
