devices of the
OLT
Multicast streams do not reach
the upstream port of the OLT.
a. Check the user terminal
following Step 2.
b. Check the ONU following
Step 3.
c. Check the OLT following
Step 4.
d. Check the upper-layer
network and devices of the
OLT following Step 5.
Step 2 Check the user terminal.
1. Verify that the TV cable is properly connected to the STB.
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 7.
l If the user cannot watch the program, go to Step 2.4.
4. Check whether all NEs are checked according to Table 5-5.
l If all NEs are checked, go to Step 6.
l If not all NEs are checked, check the remaining NEs according to Table 5-5.
Step 3 Check the ONU.
1. On the ONU, 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 5.2.1 Failure to Go
Online of a Multicast User. Then, go to Step 7.
2. Enable the ONU debugging function and collect information as follows:
a. Enable the function of multicast user monitoring on the ONU.
huawei(config)#terminal monitor
huawei(config)#terminal debugging
huawei(config)#debugging igmp user
b. Order the program again. Then, go to Step 3.3.
