Filtering IGMP Traffic Chapter 15 Configuring Multicast Services Configuring Port IP Multicast Filtering IP multicast group profiles consist of one or more ranges of IP multicast addresses that are associated with a filtering and monitoring action and are configured on a per-switch-port basis. Given a particular profile that is associated with a switch port, you can configure the filter action. • If the filter action is to permit, the matching IGMP packet is forwarded for normal processing. • If the filter action is to deny, the matching IGMP packet is dropped, discontinuing normal processing. The following sections provide switch port IP multicast filtering configurations. Adding and Listing an IGMP Multicast Filter Profile To add a multicast address or a range of addresses to an IGMP multicast filter profile, perform this task in privileged mode: Step 1 Step 2 Task Add a multicast IP address or a range of IP addresses to an IGMP multicast filter profile.
