Troubleshooting MLD Snooping

Switch Fails in Layer 2 Multicast Forwarding

Symptom
A switch fails to implement Layer 2 multicast forwarding.
Analysis
MLD snooping is not enabled.
Solution
1) Enter 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 mld-snooping enable command to enable MLD snooping in VLAN view.
3) If MLD snooping is disabled only for the corresponding VLAN, just use the mld-snooping enable
command in VLAN view to enable MLD snooping in the corresponding VLAN.
