Configuring IGMP snooping port features

Before you configure IGMP snooping port features, complete the following tasks:
•
Enable IGMP snooping for the VLAN.
•
Determine the aging timer for dynamic router ports.
•
Determine the aging timer for dynamic member ports.
•
Determine the addresses of the multicast group and multicast source.
Setting aging timers for dynamic ports
When you set aging timers for dynamic ports, follow these guidelines:
•
If the memberships of multicast groups frequently change, you can set a relatively small value
for the aging timer of the dynamic member ports. If the memberships of multicast groups rarely
change, you can set a relatively large value.
•
If a dynamic router port receives a PIMv2 hello message, the aging timer for the port is specified
by the hello message. In this case, the router-aging-time or igmp-snooping
router-aging-time command does not take effect on the port.
•
IGMP group-specific queries originated by the Layer 2 device trigger the adjustment of aging
timers for dynamic member ports. If a dynamic member port receives such a query, its aging
timer is set to twice the IGMP last member query interval. For more information about setting
the IGMP last member query interval on the Layer 2 device, see
query interval."
•
You can set the timers globally for all VLANs in IGMP-snooping view or for a VLAN in VLAN
view. For a VLAN, the VLAN-specific configuration takes priority over the global configuration.
