Troubleshooting:
1) IGMP Snooping is disabled.
Input the display current-configuration command to display the status of IGMP
Snooping.
If the switch disabled IGMP Snooping, check whether the IGMP Snooping is not
enabled globally or it is not enabled in the VLAN. If it is not enabled globally, first
input the igmp-snooping enable command in system view and then in VLAN
view. If it is not enabled in the VLAN, input the same command in VLAN view.
2) Multicast forwarding table set up by IGMP Snooping is wrong.
Input the display igmp-snooping group command to display if the multicast
group is the expected one.
If the multicast group created by IGMP Snooping is not correct, turn to
professional maintenance personnel for help.
Continue with diagnosis 3 if the second step is completed.
3) Multicast forwarding table set up on the bottom layer is wrong.
Enable IGMP Snooping group in user view and then input the command display
igmp-snooping group to check if MAC multicast forwarding table in the bottom
layer and that created by IGMP Snooping is consistent. You may also input the
display mac-address vlan command in any view to check if MAC multicast
forwarding table under vlanid in the bottom layer and that created by IGMP
Snooping is consistent.
If they are not consistent, please contact the maintenance personnel for help.
