HH3C-MULTICAST-SNOOPING-MIB
About this MIB
Multicast snooping runs on a Layer 2 device as a multicast constraining mechanism to improve multicast forwarding efficiency. It creates Layer 2 multicast forwarding entries from IGMP or MLD packets that are exchanged between the hosts and the Layer 3 device.
Use this MIB to manage IGMP snooping and MLD snooping.

Notification triggers
This notification is generated in the following situations:
The number of dynamic Layer 2 multicast forwarding entries exceeds the upper limit allowed by the device, and a protocol learned entry cannot be created.
The number of static Layer 2 multicast forwarding entries exceeds the upper limit allowed by the device, and a manually configured entry cannot be created.
System impact
The corresponding multicast services are unstable.
Status control
ON
CLI: Use the snmp-agent trap enable igmp-snooping global-entry-exceed command.
CLI: Use the snmp-agent trap enable mld-snooping global-entry-exceed command.

Recommended action
To resolve the issue:
1.Identify whether the number of Layer 2 multicast forwarding entries exceeds the upper limit allowed by the device.
- If yes, execute the reset igmp-snooping group or reset mld-snooping group command to clear dynamic IGMP or MLD snooping group entries; or execute the undo igmp-snooping static-group or undo mld-snooping static-group command to remove the configuration of static member ports.
- If no, go to step 2.
2.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.
