Troubleshooting MLD snooping

This section describes common MLD snooping problems and how to troubleshoot them.

Layer 2 multicast forwarding cannot function

Symptom
Layer 2 multicast forwarding cannot function.
Analysis
MLD snooping is not enabled.
Solution
1. Use the display current-configuration command to view the running status of MLD snooping.
2. If MLD snooping is not enabled, use the mld-snooping command to enable MLD snooping globally,
and then use the mld-snooping enable command to enable MLD snooping in VLAN view.
3. If MLD snooping is disabled only for the corresponding VLAN, use the mld-snooping enable
command in VLAN view to enable MLD snooping in the corresponding VLAN.

Configured IPv6 multicast group policy fails to take effect

Symptom
Although an IPv6 multicast group policy has been configured to allow hosts to join specific IPv6 multicast
groups, the hosts can still receive IPv6 multicast data addressed to other groups.
Analysis
The IPv6 ACL rule is incorrectly configured.
•
The IPv6 multicast group policy is not correctly applied.
