Specifying the IGMP snooping version

Different versions of IGMP snooping process different versions of IGMP messages.
IGMPv2 snooping processes IGMPv1 and IGMPv2 messages, but it floods IGMPv3 messages in
•
the VLAN instead of processing them.
IGMPv3 snooping processes IGMPv1, IGMPv2, and IGMPv3 messages.
•
If you change IGMPv3 snooping to IGMPv2 snooping, the device does the following:
Clears all IGMP snooping forwarding entries that are dynamically added.
•
• Keeps static IGMPv3 snooping forwarding entries (*, G).
Clears static IGMPv3 snooping forwarding entries (S, G), which will be restored when IGMP
•
snooping is switched back to IGMPv3 snooping.
For more information about static IGMP snooping forwarding entries, see
To specify the IGMP snooping version:

2. Enter VLAN view.
3. Specify the IGMP snooping

Setting the maximum number of IGMP snooping forwarding
entries
You can modify the maximum number of IGMP snooping forwarding entries. When the number of
forwarding entries on the device reaches the upper limit, the device does not automatically remove any
existing entries or create new entries until some entries time out or are removed. In this case, HP
recommends that you manually remove the excessive entries.
To set the maximum number of IGMP snooping forwarding entries:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
