Operation Manual – Multicast ProtocolH3C S3610&S5510 Series Ethernet Switches Chapter 3 MLD Snooping Configuration3-9z Configure the corresponding port groupsBefore configuring MLD Snooping port functions, prepare the following data:z Aging time of router portsz Aging timer of member portsz IPv6 multicast group and IPv6 multicast source addresses3.4.2 Configuring Aging Timers for Dynamic PortsIf the switch receives no MLD general queries or IPv6 PIM hello messages on adynamic router port, the switch removes the port from the router port list when the agingtimer of the port expires.If the switch receives no MLD reports for an IPv6 multicast group on a dynamic memberport, the switch removes the port from the outgoing port list of the forwarding table entryfor that IPv6 multicast group when the aging timer of the port for that group expires.If IPv6 multicast group memberships change frequently, you can set a relatively smallvalue for the member port aging timer, and vice versa.I.
