Configuring Basic Igmp Snooping Features; Enabling Igmp Snooping; Specifying An Igmp Snooping Version - HP MSR1002-4 Configuration Manual

The IGMP snooping configurations made on Layer 2 aggregate interfaces do not interfere with the
configurations made on member ports. In addition, the configurations made on Layer 2 aggregate
interfaces do not take part in aggregation calculations. The configuration made on a member port of
the aggregate group takes effect after the port leaves the aggregate group.

Configuring basic IGMP snooping features

Before you configure basic IGMP snooping features, complete the following tasks:
•
Configure VLANs.
•
Determine the IGMP snooping version.
•
Determine the maximum number of IGMP snooping forwarding entries.
•
Determine the IGMP last member query interval.

Enabling IGMP snooping

When you enable IGMP snooping, follow these restrictions and guidelines:
•
You must enable IGMP snooping globally before you enable it for a VLAN.
•
IGMP snooping configuration made in VLAN view takes effect only on the member ports in that
VLAN.
•
You can enable IGMP snooping 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 enable IGMP snooping for the specified VLANs:
Step
1. Enter system view.
2. Enable
globally
IGMP-snooping view.
3. Enable IGMP snooping for
the specified VLANs.
To enable IGMP snooping for a VLAN:
Step
4. Enter system view.
5. Enable
globally
IGMP-snooping view.
6. Return to system view.
7. Enter VLAN view.
8. Enable IGMP snooping for
the VLAN.
