Analysis
The ACL is incorrectly configured.
•
• The multicast group filter is not correctly applied.
The function of dropping unknown multicast data is not enabled, so unknown multicast data is
•
flooded.
Solution
1. Use the display acl command to verify that the configured ACL meets the multicast group filter
requirements.
2. Use the display this command in IGMP-snooping view or in a corresponding interface view to
verify that the correct multicast group filter has been applied. If not, use the group-policy or
igmp-snooping group-policy command to apply the correct multicast group filter.
3. Use the display igmp-snooping command to verify that the function of dropping unknown multicast
data is enabled. If not, use the drop-unknown or igmp-snooping drop-unknown command to
enable the function of dropping unknown multicast data.
4. If the problem persists, contact HP Support.
