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 value 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.
• 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.
