IP Multicast Filtering
Issue 2 July 2005 145
Figure 25: IP Multicast Filtering in Action
IP Multicast Filtering configuration is associated with the setting up of three timers:
● The Router Port Pruning timer ages out Router port information if IGMP queries are not
received within the configured time.
● The Client Port Pruning time is the time after the C360 switch reset that the filtering
information is learned by the switch but not configured on the ports.
● The Group Filtering Delay time is the time that the switch waits between becoming aware
of a Multicast group on a certain VLAN and starting to filter traffic for this group.
Figure notes:
1. Network with no IP Multicast Filtering
- PC generates traffic for multicast group A
- All other PCs receive the traffic whether or nor they require it.
2. Network with IP Multicast Filtering
- Only PCs that have registered with group A receive the traffic
