2. Check the indicator status of the STB. If the indicator of the STB Ethernet port blinks
quickly, the STB decoding may be incorrect. Reset the STB or use a functional STB.
3. Order a program to check whether the user can watch the program successfully.
l If the user can watch the program successfully, go to Step 6.
l If the user cannot watch the program, go to Step 2.4.
4. Check whether all NEs are checked according to Table 4-5.
l If all NEs are checked, go to Step 5.
l If not all NEs are checked, check the remaining NEs according to Table 4-5.
Step 3 Check the MA5612.
1. Run the display igmp user user-index command to query the multicast user status
(State).
l If State is online, go to Step 3.2.
l If State is offline or block, perform operations by referring to 4.2.1 Failure to Go
Online of a Multicast User. Then, go to Step 6.
2. Enable the MA5612 debugging function and collect information as follows:
a. Enable the function of multicast user monitoring.
huawei(config)#terminal monitor
huawei(config)#terminal debugging
huawei(config)#debugging igmp user
b. Order the program again. Then, go to Step 3.3.
NOTE
After the preceding steps are performed, run the following commands to disable the debugging
function.
huawei(config)#undo debugging igmp
huawei(config)#undo terminal debugging
huawei(config)#undo terminal monitor
3. Find the possible cause according to judgment criteria described in Table 4-6 and then
troubleshoot the fault. Then, go to Step 3.4 to check whether the fault is rectified.
