Fault Scope Possible Cause
MA5612 On the MA5612, check whether the multicast user is online and then
troubleshoot the fault according to the following symptoms:
l If the multicast user is offline or is blocked, troubleshoot the fault
by referring to 4.2.1 Failure to Go Online of a Multicast User.
l If the multicast user goes online but blank screen occurs in the
multicast program, the fault is generally caused by incorrect
multicast configurations on the MA5612. In this case, enable the
MA5612 debugging function and then locate the fault according
to the debugging information displayed on the CLI. Possible
causes:
– The remaining multicast bandwidth of the user is lower than
the required bandwidth of the ordered program.
– The number of programs watched by the multicast user reaches
the upper limit so that the user cannot order a new program.
– The multicast user does not have the permission to watch the
program.
– The program ordered is not in the MVLAN to which the
multicast user belongs.
– The multicast user does not have the permission to order certain
types of programs (such as HDTV).
– The number of programs at a level watched by the multicast
user reaches the upper limit so that the user cannot order a new
program at this level.
– The rate configured in the traffic profile bound to the traffic
stream is far lower than the bandwidth of the multicast program.
– There are too many prejoined static programs, occupying too
many bandwidths.
Upper-layer
network and devices
(including the
multicast router and
multicast server) of
the MA5612
l The program is not configured on the multicast server.
l The time to live (TTL) value set for the multicast stream of the
multicast server is very small.
l The network communication fails. The network communication
failure occurs on the line between the MA5612 and multicast
router, and between the multicast router and multicast server.
CAUTION
To facilitate fault report, save the results of the following steps.
Procedure
Step 1 Order a program again and perform the following steps to determine the location where program
traffic interruption occurs.
