Setting The Maximum Number Of Igmp Snooping Forwarding Entries - HP MSR1002-4 Configuration Manual

•
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
You can specify the version for the specified VLANs in IGMP-snooping view or for a VLAN in VLAN
view. For a VLAN, the configuration in VLAN view has the same priority as the configuration in
IGMP-snooping view, and the most recent configuration takes effect.
To specify an IGMP snooping version for the specified VLANs:
Step
1. Enter system view.
2. Enable
globally
IGMP-snooping view.
3. Specify an IGMP snooping
version for the specified
VLANs.
To specify an IGMP snooping version for a VLAN:
Step
1. Enter system view.
2. Enter VLAN view.
3. Specify an IGMP snooping
version for the VLAN.
Setting the maximum number of IGMP snooping forwarding
entries
You can modify the maximum number of IGMP snooping forwarding entries, including dynamic
entries and static entries. When the number of forwarding entries on the device reaches the upper
limit, the device does not automatically remove any existing entries. As a best practice, manually
remove some entries to allow new entries to be created.
To set the maximum number of IGMP snooping forwarding entries:
Step
1. Enter system view.
2. Enter IGMP-snooping view.
3. Set the maximum number of
IGMP snooping forwarding
entries.
